Balloon Inquiry: What Will Happen And Why?

This was originally posted at the High Hopes Project web site.

Note the 4 party balloons that all started out the same size before they were inflated, on their way to 30,500 meters (100,000 feet ) from a balloon flight last year. On our upcoming flight we will inflate 4 of the same size balloons – the first balloon will be inflated to about 1/4 of its capacity (like the yellow balloon in the photo), the second balloon to about 1/2 of its capacity (see the green balloon above), the third to about 3/4 its capacity (Note the orange balloon), and the fourth balloon will be inflated close to full (Note the red balloon above). What will happen to them during the flight? What are the characteristics of the atmosphere that may effect them and what, if any, will that effect be? Explain your conclusion.

When we launch the “High Hopes” high altitude weather balloon we will include this experiment. We will have a camera recording what happens to the balloons and share those images with you after the flight in late April or early May 2015. So do your research about our atmosphere, discuss with your collaborators, do some heavy thinking, then write what you think will happen. You could even leave your written thoughts here as a comment if you’d like.

Now You Can Submit High Hopes For The World With Twitter!

NOTE: This post was originally posted on the High Hopes Project Blog:

When we launch our balloons to 100,000 feet (30,000+ meters) this spring, the world’s high hopes will go with them. Now we’ve made it even easier to submit a “High Hope” using Twitter. Just “Tweet” your “High Hope” for the world, include the hashtag #hhpstem – and we’ll get it and include it in a payload that will take it to near space and then release it to spread around the world. So your “High Hope” will really go high!

We suggest however that having your students write their “High Hopes” for their school, community and the world might need more than 140 characters so then, as we shared in our last post:

“When we first designed the “High Hopes Project” years ago, we went about making sure it stressed not just the powerful content writing experiences about the science and engineering, but the creative writing we knew it would motivate students to engage in. We’ll share more of those along the way, but having students brainstorm, discuss, and share what their “high hopes” are for their school, community and the world turned out to be gold. Most students (maybe adults too) just don’t think about what can and could be.

Originally we had our students write those three “hopes” … school, community … world. We posted general steps, but we have no strict rules about how you submit your “Hopes.” They can be just be one “hope” per student … a “class” hope that the class develops … it is up to you. “Hopes” could also be written as a poem or short story. Once done, you submit them here.”

Either way is fine, you decide. But you just might want to send your own “High Hope” to us quickly through Twitter … and now you can! Remember the hashtag #HHPSTEM  – you can even send more than one!

Making and Taking Flight

When experienced using a truly integrated approach, STEM learning is, I believe, the most powerful language arts program there is. The reason so many still struggle with STEM is that they approach it as an “add-on” … something else they have to make time for instead of embracing it as a culture. Yes, it takes time to cultivate that culture where students have learned to work together to solve problems and make things. It also means changing how you run your classroom and you have to give up, at least some of the time, the siloing of subjects and your daily schedule.

Unfortunately, demonstrating and providing experiences for teachers that include even a smattering of the possibilities during a 75 – 90 minute presentation is quite possibly impossible. But we keep trying to do so because we keep being asked to. My boss wants me to set up some 16 hour classes next school year (I’m already overbooked for this year) that will provide more time to experience what that is like from the student point-of-view, so that is definitely on my radar for next year.

Yesterday we were asked again to do our best to make that connection between ELA and STEM at the local Reading Conference for teachers. Here is how we went about it:

We believe it is key to have teachers learn their ABC’s. Not as in the alphabet, but as in Activity Before Content. So we began with an activity. The science reading our students (actually the teachers in our session) would take on was about flight and specifically dealt with lift, drag, thrust and gravity. We did not front load the vocabulary as is common practice, instead we used the activity to give them schema.

We passed out a balsa wood prop plane to each group of 3 to 4 teachers and instructed them to put them together. We gave no other instructions.

We noted that every group actually read, discussed and followed the directions on the package! 🙂

Once finished, teachers were asked to discuss and write about the construction experience, then what ways their plane could be “adjusted” to achieve the longest flight possible. We had them share a few of their answers but made no comments on whether their ideas would truly make a difference. Then we found an empty hallway for the 50+ participants to fly the 18 planes we had passed out. We also gave them a 10 meter measuring tape and had then bring the science notebooks we had them make along, but again, did not tell them what to do with them if anything.

The groups staked out spots to fly and we observed intently.

Most groups decided to throw their planes after winding the propeller rubber band what seemed to be the “right number” of spins. One group launched their plane from the ground because they felt that throwing it wasn’t consistent and could skew the data they were collecting. Then we started to see groups were counting the number of turns of the propeller so that their data would be “more comparable.” Next some were making tweaks to the wing position and so on to achieve a straighter flight and more. So they were discovering things about flight and how their planes functioned through experience, NOT because we took class time to lecture and demonstrate the “right” way.

It was a 75 minute presentation, so that was all the time we had for flying. We returned to class and had them journal about their experience for 3 minutes or so and then did a quick debrief. During our discussion it was noted that these planes are not a perfect way to do inquiry science/engineering because there is no way to control all the variables. Even if you wind the propeller the same number of turns each time the way the rubber band winds up is different and could effect the flight. releasing the plane if you give it a toss is problematic because you can’t be sure you gave it the exact same toss and released it at the exact same angle. When it lands (usually crashes) the wings and tail get moved … did you put them back exactly where they were the last time? Launching from the ground is easier to control overall, but did you let go of the propeller and the plane at the same time and way each time …. and more … you get the idea. So this is a great and motivating way to teach the steps of doing inquiry, but just realize the data produced is slightly unreliable at best.

Note that if you did this activity in your classroom, what we did during the presentation would be how you would introduce the activity. You are just letting students have time to become familiar with how these things work. Next you would get into why this isn’t a perfect inquiry piece but ask them for ways to control the variables as best as possible so we can learn how to get the longest, straightest (or whatever you and they decide to learn about – maybe all of these and more). Perhaps you would agree to launch from the ground behind a line. Do you measure to where the plane ended up, or mark where it first hit the ground? All these decisions lead students to understand how inquiry is done … let them figure it out as much as possible with you playing the role of “reluctant guide” – only helping with advice or opinions when you judge you just have to to move things along. HAVE students take photos, video clips, take notes … even though they will balk at that to keep making flight after flight …. solid science and engineering require descriptive note taking and data collection.

 

Next we handed out some leveled science readers that had the same article about flight, with the same illustrations and charts, just written at different reading levels. Teachers were then instructed to read the article closest to their grade level (K-1, 2-3, 4-6, 6-9 or so) and take notes on the connections between their activity and what they learned from the reading. When they shared out teachers mentioned how the vocabulary was more interesting and meaningful to learn about because they had experienced them during the activity ( lift, drag, thrust and gravity). In addition because the article was about a flight around the world in a propeller powered plane they understood more of the issues the main character had experienced … and they were just more motivated to read it period because they had assembled and flown their own plane.


We quickly made the point that what they had just experienced in 40 minutes would easily be 1 to 2 weeks in the classroom with all the flights, data collection, journaling, creative writing possibilities, analyzing the data in math, re-enginnering to achieve longer or straighter or finding out what the “best” number of turns to put on the rubber band is and on and on. Imagine connecting with another class anywhere in the world doing the same inquiry and sharing data and discussing results and stories of the good, bad and ugly of what happened during all the flights. How could you bring art in? History? Guest speakers?

We next shared some of the connections to the Next generation Science Standards and shared some other resources and our time was up.

Next Design Challenges For Students

Originally posted at the High Hopes Project Blog

Lots has happened since we last checked in with students at Sparks High School that are designing and engineering several of the payloads we will send up to 100,000 feet (33,000 meters). The students finished one design for releasing the world’s High Hopes. The plan is to solicit the world’s “Hopes” – (you can add your students’  “Hopes” here) print them out on small strips of paper that will biodegrade rapidly, release them at 100,000 feet or higher and then have them spread out over the world and become one with the Earth. The challenge is to make that happen under the severe conditions the payload will experience.

Above is the simple, lightweight design that includes a framework inside to mount a camera that will record the release of the “High Hopes,” as well as a latch to hold it closed. Next we will turn the payload over to Sparks Middle School students to design a way to open the payload at just the right time. The high school students are also working on a second release payload that will release some of the “Hopes” at a lower altitude – local elementary students are designing some of the “Hopes” so they will glide or helicopter down … but that has to happen at a different altitude for reasons we will leave to you and your students to figure out. 🙂

Next we shared the other engineering design problems the high school students will take on. One of our launches will be from Lake Tahoe. We were working out how to do that last year when we had this failure and this success, Now we plan to drop cameras over 100 feet deep in the lake and part of that camera package will include a water pressure gauge the students have to design and build (they will also need to become familiar with Noble Gas Law). One of the cameras will track the gauge to record the water pressure from it’s deepest point to the surface of the lake. An air pressure gauge will also be deployed on the payloads above the surface. We will share the data from those and other readings … your students can inquire to figure out what will happen to those readings during the flight as well as temperature and other readings.

In addition, they have to reel the 100+ feet (33+ meters) of line the cameras and gauge are attached to back up to the other payloads so they aren’t dangling, possibly causing instability. So after they break the surface of the lake, those need to be retracted.

As a model STEM project, one of our goals is to set up collaborations not only between students at various schools, but also between students and engineers. The Mechanical Engineering and Materials Science departments at the University of Nevada, Reno, are experts in high altitude ballooning, and they have agreed to mentor our student participants. So on this visit we brought along Sierra Adibi,  a junior in the mechanical engineering department. Her minor is in unmanned autonomous systems … so we felt she just might be a good fit. 🙂

Above: Sierra answered their questions and gave them some background and ideas on how they might utilize the Noble Gas Law in their water pressure gauge design. She also noted materials they were utilizing and asked questions about what they needed to consider for the conditions their designs have to deal with. Such a great opportunity to have students connect with people really working in the field … to see what others are doing. We’re planning to have Sierra come back to talk to the students more about the note-taking and writing pieces required for this kind of work. Their teacher, Mr.Walsh mentioned that students were struggling somewhat with those skills and Sierra offered to return soon with examples.

Finally we also gave them a problem to start on we will share at a later date. However it does tie-in nicely with the paper airplane design project Mr. Walsh already has planned in the coming month. Needless to say, by the end of the discussion it was hard to tell who was more excited, the students or us! With all the challenges the high school students are given, they are turning over some of the design and building over to the middle school and elementary students as needed. The whole world can join in by learning about the characteristics of our atmosphere and water, drawing informed conclusions and then using the data and media we will share after our launches to see if their conclusions were correct.  We’ll share more about how anyone can be part of this project in future posts.

What are your “High Hopes!?”

Next we meet with the middle school and elementary students to inform them of their challenges.

Learning is messy!

High Hopes Project 1st Design Meeting

I posted this over on our “High Hopes Project” blog  and decided it fit well here too:

We refer to The High Hopes Project as a “model” STEM project. One aspect of that modeling is that we’ve designed it to include as many ways to participate as possible. To do so we have set up (so far) a project web site, this  blog, a Twitter account, a Flickr account, a YouTube Channel, a Wiki and a Gmail account so we have access to tools like Google Forms for archiving and analyzing data.

In addition, any class or person can participate in the experiments we will send up by researching and theorizing based on what should happen, and then analyzing the data we gather and share about the atmosphere including temperature and pressure and in sending up the world’s “High Hopes” – including yours (more explanation about those aspects will be shared along the way – we don’t launch balloons until April and May) .

However another characteristic of this project is we chose 3 local schools to participate in certain engineering designs for the project to act as surrogates for all of us (an elementary, middle and high school). We contemplated opening up the major engineering design portion of this project to the world, but realized quickly that receiving design ideas from potentially tens if not hundreds of classes from around the world would be beyond our time constraints and abilities to judge and implement.

Doug Taylor who co-designed this project looks on as a student explains the mock-up of the High Hopes payload and release mechanism the class is engineering and building.

 

The first one of the engineering challenges the students in Mr. Walsh’s physics class at Sparks High School are tackling is how to release the “High Hopes” the world submits so they can be spread around the world – more than likely they will be printed on small strips of paper – the paper we use breaks down in the environment in a matter of weeks BTW, so our High Hopes will become one with the Earth. One batch of the High Hopes will be designed to helicopter or glide in the air (to be designed by the elementary students) and have to be released at a lower altitude, but the bulk of the High Hopes will be released as high as possible (around 100,000 feet or 33,000 meters). So that requires 2 payloads.

The students informed us a week ago that they had done some initial designing and had some mock-ups to show us, but more importantly had questions about requirements and conditions to deal with. We set up a time to meet with them and included Andy Smith who is a mechanical engineering graduate student at the University of Nevada, Reno. Andy is close to receiving his doctorate degree in engineering and has launched over 50 balloons himself, as well as designing payloads and the communications devices required to track them so they can be recovered. He has agreed to consult with students throughout the project.

IMG_2800The students showed us 2 designs – one basically a pyramid shape they envision being a bit more aerodynamic and stable, and another shaped more like a rectangular prism. The rectangle design also had a rudimentary release mechanism built in. They had chosen styrofoam sheets,  as the material … oh and the ever ubiquitous duct-tape.

One question they had was about payload size. They had no idea just how many “High Hopes” they had to transport, but they assumed about a ream of paper worth (500 sheets). In fact they had placed a ream of paper inside their initial designs and dropped them from their school building as an initial test and both survived intact. We explained we really had no firm idea just how many we might receive over the months before we launch, but that their test seemed like a good start.

 

Andy answered their questions about release mechanisms and how to release the High Hopes at the right moment. They discussed the possibility of using arduinos they could build and program, perhaps based on altitude readings. Andy also made them aware of some of the other design issues they would have to overcome including temperature, high and very low humidity, and high winds …  and that some glues and other materials don’t do well under certain conditions.

Learning is Messy!!

Close Reading? OK, How About Close Doing?

Reading

 

 

 

 

 

 “Reading” Sebastien Wiertz

Close reading is one of the “strategies du jour”.

From the Common Core State Standards in ELA:

1. Read closely to determine what the text says explicitly and to make logical inferences from it; cite specific textual evidence when writing or speaking to support conclusions drawn from the text.

In addition from the Harvard Writing Center:

The second step is interpreting your observations. What we’re basically talking about here is inductive reasoning: moving from the observation of particular facts and details to a conclusion, or interpretation, based on those observations. And, as with inductive reasoning, close reading requires careful gathering of data (your observations) and careful thinking about what these data add up to.

In pretty much all trainings and presentations I deliver about STEM learning, I stress how STEM is language intense. I go so far as to state that it is one of the most powerful language arts interventions available. But that is only true if you take advantage of the language learning (and loads of other learning possibilities) that STEM provides.

STEM learning is somewhat its own enemy because often the activity or experience involved is so interesting, intriguing or engaging (or all 3) that the students get excited and talk about it excitedly (and often parents voice how excited their child was when they came home) and teachers assume everything (or enough) important was learned. What is probably more often the case is that the lesson/learning experience was just about the STEM learning and integrating the language arts either isn’t part of the plan, the time to integrate isn’t perceived as important, or the usual issue of not feeling there is time rears its head.

This is a powerful learning opportunity missed. Really opportunities missed. Let’s focus on just one. Instead of “close reading,” we’ll refer to it for lack of a better name as “close doing” (but we could call it “close making” or “close observing” or other possibilities).

I point out repeatedly how too often field trips or major hands-on activities (doing or making activities) are planned to be experienced  as either stand alone experiences or end of unit experiences with little to no emphasis on how they tie to the overall learning plan. Will the learning be integrated into all subjects or are those connections just assumed to be made? What if instead these experiences were provided early on in the unit? Example: Students are learning about animals- adaptations, habitats, and so forth. After a bit of learning about what adaptations and habitats are, we take a trip to a zoo or wildlife park to observe and learn about animals. Students are required to take notes and ask questions about the animals habitats and adaptations and take digital photos and video clips of animals, but also information displays and more.

Trips like these are usually exciting for students and even lead them to wonder and wanting to learn more. But often (as stated above) this also marks the end of the unit; “That was fun kids, next week we start learning about the planets!” Here’s where I propose “close doing” comes in. Using students memories, notes and photos (which I always archive somewhere like Flickr (free) so students, families and collaborators have access to them) we make close observations about each animal – what were some of the characteristics of each animal that helped them adapt (claws, fur, shells, eye size, … ) – colors, but more – not just white, but creamy white and white like a cloud or milk – even emphasize really what color white was it, cloud white? Pearl white? Cream white? Which is the best descriptive color, or texture, or simile to something man-made for example.

All the senses should come to bear: What did animals, their parts, their habitats, etc. look like, feel like (or look like they feel like if you couldn’t really touch them)) smell like, sound like … go deep! This takes time AND should probably happen during your language block, not just a science period (but could be both) because this is language study as much as it is science. Students should be taught and challenged to be close observers and inferrers. Just as close as they have to be when they are close reading.

The same is true for the hands-on activities- the doing and making experiences the students have. What did you observe during that experiment or construction/engineering piece? What were all the happenings, colors, actions, reactions and so on that you saw and explain what each one had to do or didn’t have to do with the overall result?  Thinking “close” about how you observe and do and problem solve and more, about any of these aspects of a project or unit. (NOTE: You wouldn’t do the super intense “close doing/observing” with every part of the project – that’s as stifling as overdoing close reading – I’m saying consider picking some part of the learning or doing and do it every once in a while – a couple/three times a year maybe – then you have built and practiced those essential skills and have those “close doing” schema experiences to relate to in other subjects as well).

Just like it takes many readings and lots of probing questions to facilitate “close reading” skills and thinking, the same is true of observing and noting all of what was observed and/or done in “close doing.” Getting students to note all the meaning is the goal here too.

The vocabulary that comes from these experiences is amazing … and because it is based on schema all the students build together, and have in common, it becomes a valuable reading instruction resource later; “Remember when we saw that bear at the zoo and he seemed both scary and cuddly at the same time? How does this character remind you of that? Or how is this character different than that?” OR “Remember how we noted that the bear’s fur was brown like the bark on a redwood tree?” Why do you think this author chooses the colors she uses to describe the buildings and streets in this chapter?”

Then, because students have thought and taken notes about not only facts, but color, texture, actions, behaviors, and much more, they are scaffolded to write incredible descriptive poetry, stories, captions for the photos they took, narrations for videos that share and assess their learning and so much more.

“The second step is interpreting your observations. What we’re basically talking about here is inductive reasoning: moving from the observation of particular facts and details to a conclusion, or interpretation, based on those observations. And, as with inductive reasoning, close reading requires careful gathering of data (your observations) and careful thinking about what these data add up to.”

Remember this quote about close reading above? Re-read it and note how it fits with STEM learning. Ingesting  that motivating, hands-on learning and taking the time to “interpret” it – then sharing through text or video, or podcast, or any number of other publishing portals … and preferably shared online to promote and obtain the benefits of connected and collaborative learning as well – emphasizing that “close” idea, just not only with text.

Let’s change out some of the words from the definition of close reading from above:

Think about and do closely to determine what the research, experience, investigation and inquiry says explicitly and to make logical inferences from it; cite specific _ evidence when writing or speaking to support conclusions drawn from the research, observation, collaboration, inquiry and experience.”

So what I am saying is, is that STEM or inquiry learning is just as important and valuable a language arts learning opportunity as reading text, if the vocabulary and writing and research are emphasized and connected to close thinking and inferencing skills. And it provides another avenue or method to connect students struggling to interpret text to thinking about and explaining meaning and learning. Not saying it takes the place of reading text, just that it is as important to do because students are just as weak at interpreting, citing and inferring from other inputs, and articulating from them is just as important.

And if you build students “close doing” skills, the next time you are doing “close reading” – you have built schema for being successful at that as well: “Remember how long it took us to come up with “redwood bark” as a great description of the bear’s fur? How frustrated we were for awhile? But then when we came up with that and saw how near perfect it was as a description … how excited and motivated we were? That’s what we have to do now as we think about this text passage.”

Also note – if you are trying to jam STEM learning into a crowded schedule (STEM is a culture, not a time of day or day of the week), here is your valid reason and method to truly integrate it.

Nevada Tahoe Teacher STEM Institute

3 weeks ago we participated in the Nevada Tahoe Teacher STEM Institute. Over 50 K – 9 teachers from all over Nevada came to the Tahoe Environmental Research Center (TERC) at Sierra Nevada College in Incline Village, Lake Tahoe, for a week of STEM learning. The funding was based on a Math/ Science Partnership Grant we wrote and received through the Nevada Department of Education. The event was put on by the Nevada’s Northwest Regional Professional Development Program, Washoe County School District, TERC, along with help and support from others mentioned in this post. BELOW: We started off with a group photo.

Besides the more than 40 hours of training, participating teachers each received lessons, supplies and other resources to take back to their classrooms and students so they can use what they learned right away. In addition teachers will have monthly follow-up sessions to share their progress, ask questions, share resources they have developed and make connections through the classroom blogs, wikis and Flickr accounts they set-up. It was an intense and rewarding week of learning and sharing in one of the most beautiful locations on Earth!

Why should education leaders embrace digital technologies in their schools?

Why should education leaders embrace digital technologies in their schools? leadershipday2014_01-300x240

1) If you are in a state that adopted the “Common Core State Standards” (CCSS) you really don’t have a choice. There are many (yes many) English Language Arts standards alone that require students as young as kindergarten to use technology to read, produce and publish digital content and to collaborate in doing so. Just a few examples from the CCSS:

K – 12 – Use technology, including the Internet, to produce and publish writing and to interact and collaborate with others.

K-12 – With guidance and support from adults, explore a variety of digital tools to produce and publish writing, including in collaboration with peers.

6th grade – (NOTE: by 6th grade the “… guidance and support from adults …” is gone. 6th graders are to master this standard on their own) Use technology, including the Internet, to produce and publish writing as well as to interact and collaborate with others; demonstrate sufficient command of keyboarding skills to type a minimum of three pages in a single sitting.

5th grade –  Analyze how visual and multimedia elements contribute to the meaning, tone, or beauty of a text (e.g., graphic novel, multimedia presentation of fiction, folktale, myth, poem).

I’m not sure how we get our students to the mastery of these standards, and many others without ubiquitous access to and utilization of the technologies required.

2) Collaboration – This was already stated in the standards above, but those were specifically language arts standards. Communication and collaboration are already key to being educated, but also in getting a job. Learning to collaborate with the student next to you in class or in your group is great, but technology makes it easy (yes, easy) to collaborate globally. Will it be “good enough” if students just learn to collaborate in class? Will that foster solid collaboration skills with today’s (and tomorrow’s) technologies? Not that getting a job is the only reason to learn solid collaboration skills, but getting a job without having those skills is not getting easier. Mastering all the ways collaboration is leveraged personally and using technology is vital.

3) Programming and design – 3D printing (did you know they are printing whole houses, food and blood vessels already?), also –  software development, engineering, graphics, architecture, transportation, art, medicine,  and much more all rely on programming and design skills … this is what is happening now in fields with good paying jobs.

4) Inventing (often referred to as “making” these days) – This is hands on and motivating and requires the skills developed through pedagogy that includes all of the above.

5) Problem solving – (See above)

So you think children are already mastering these skills and technologies on their own by using their smart phones and other technology 24/7? Ok, let’s see how that works out with your students.

I don’t pretend that I’ve included all the reasons that leaders should consider (please add your own in the comments). But these are not easy or cheap changes that have to happen. We’re not going to provide the technology and professional development and commitment to change on the cheap. Only real leadership will get us there.

Messy Balloon Launch – Failure is a Teacher

I’ve been “Tweeting” out from time to time lately about our latest “High Hopes” balloon launch. This balloon launch is different from launches we’ve done in the past in that students are not directly involved … but this flight is really all about getting students to be involved.

We have big plans for a project next year that will involve students, but we need to try out a few new twists and some new technology and that is complicated. In addition, one of our ulterior motives is to try things that won’t necessarily work or go well …  and so we’ll turn our ideas, results, and  problems over to students for them to engineer and re-engineer. It’s all part of that engineering design process.

In fact, some of what we are attempting is so complicated we experienced a failed launch yesterday. Part of the failure was trying to figure out the procedures required to launch a balloon from and in the water. This involves having divers in the water and has not been tried before so we were working it out. Our failure mostly resulted however, from trying to launch when the wind was just too gusty and unpredictable. Here is the video of the second balloon that popped on the ground:

This video was actually shot by a camera that was laying on its side waiting to be dropped into the lake … I rotated the image so it is easier to watch. The balloon is blown right into the kayak paddle … and that was that. We are monitoring the wind and will make a new attempt to launch next week when all members of the team have time and it isn’t a windy day … AT ALL … so watch for the results … if things go as planned we should get back some great photos and videos.

A more important reason for this post however is that if school was still in session I would be sharing this story with students and teachers … and I plan to in the future. I would also share this video of a NASA balloon launch gone astray that almost killed people and caused millions of dollars in damage. I have shown this commercial of Michael Jordan explaining the power of failure as well. (How many examples can you think of right now to add here? I bet a bunch.)

Students have to understand that adults and even “experts” have things, “not go as planned,” and that how we process and handle that is vital. This is the crux of “messy learning.” That the process should not purposely involve careless, especially dangerous mistakes born of disregard, but that analyzing and learning from mistakes is how learning evolves. We should be teaching this through the experiences happening in and out of our classrooms.

That takes time … learning and doing  that are important involve dealing with complexity and the complications that can only be realized by attempting complicated things. That kind of learning and doing can’t always be put on a tight schedule, nor should it. It also can’t always be planned or experienced the same across 2 or more classrooms on the same grade level when teachers are meeting in PLCs. Complexity and learning happen beyond what we can plan and we must embrace that more in our schools. To be fair I think most believe that, where we fall down is in not REALLY embracing it and allowing it to happen … even sometimes.

This messy learning is a big part of what STEM is about. Beyond the learning being messy, the planning, administration, scheduling and implementation are messy as well. And somehow it has to be OK that they are messy.

Sharing our failures and our thinking, planning and implementation after failure is one important aspect we don’t often give the respect it deserves in our schools.

Learning is messy!

Story of a 3D Printed Whistle

Pavel Solin is an associate professor in the Applied Mathematics Department at the University of Nevada, Reno, and the founder of NCLab, an open public cloud computing platform that provides free web browser access to open source software related to computer modeling and scientific computing. I teamed up with him earlier this year to teach a coding class for teachers ….  well he taught it, I set the class up and took attendance basically.

Pavel contacted me this week with a story about elementary students engineering a whistle that might actually work – I’ve cut and pasted his blog post about it below. I am adding video clips of trying the printed out designs. One aspect that amazes me is that the printer prints out the ball inside the whistle … inside the whistle!

I’ve seen many examples of figures printed out on a 3D printer … and they are impressive. Students have to figure out and problem solve coding the design to get it just right. But this is different in that students aren’t just printing out a figure that looks like a whistle, they are using the engineering design process to make a whistle that actually works … hopefully.

Understand that in this instance students were scaffolded along the way by their teacher. I was thrilled when Pavel gave me the 3 whistles to use as examples. I’m really looking forward to trying projects like this once the 3D printer I am building from a kit is finished (2 days from now is the goal!).

 Pavel’s post with my addition of video clips:

Story of a Whistle

Few days ago, kids from the Schurz Elementary School in Mineral County School District, supervised by Jeremy Elsmore, designed a whistle. I was amazed by the idea of creating something that works. So far, all 3D models I saw were just for display. Here it is. The ball inside the chamber is cool. Once printed, it will remain trapped there forever.

Naturally, the students were anxious to see whether the 3D print would produce sound. Me too.
01b

Click the video link below to see if this whistle design works!

 

But unfortunately, it did not. The symmetry cutplane reveals that all the air blown into the whistle leaves through the large opening before entering the chamber, and even before hitting the opposite edge.

Second Design

Kids sometimes tend to give up when something does not work. This example can be used to show them that when something does not work, that’s not the end at all. On the contrary – it’s the beginning. To force the air into the chamber, the design was changed:
02a

To better see how the whistle is arranged inside, here is the symmetry cutplane again:
02c

And, this is the 3D print:
02b

Click the video link below to see if the second “re-engineered” design works.

 

 

Nice, right? Do you think that it worked? Nope. Argh!

 

Third Design

The whistle is not a simple thing at all. We googled for schematics of whistles but those we found were not very useful. We also watched several YouTube videos showing how to create a whistle. But all of them were using a different design, without the ball and chamber, based just on a short straight piece of wood. Nevertheless, in all of them, the edge that is hit by the streaming air was sharp. That’s what we did in the third design:
03a

Again, here is the symmetry cutplane that reveals the internals:
03c

And finally, this is the 3D print:
03b

Will the third try be the charm? Click the video to find out:


So what else could be designed and printed that actually is a working product? I already thought up designing a whirlybird design that flies on its own. What else?
