Ocean Gyres and Plastic Pollution Solutions

Designing an NGSS aligned STEM inquiry for 5th grade

Plastic pollution in an ocean gyre. Some floats on the surface, but more floats beneath the surface.

I’m currently involved in designing a 5th grade inquiry experience aligned to NGSS – I’m actually part of a team of 3. I volunteered (or was volunteered, not sure) to design a Plastic Gyre that 5th grade students will then design a system to collect the plastic from. These gyres full of plastic debris actually exist in the ocean, and as I recently noted even in mountain lakes like Lake Tahoe.

 

NGSS Standards: 5-ESS3 Earth and Human Activity 5-ESS3-1. Obtain and combine information about ways individual communities use science ideas to protect the Earth’s resources and environment.

Supports: 3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
3-5-ETS1-2. Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

Here’s a video that will explain why we decided this was a good problem to address:

I’ll share more about what we’re up to in future posts, but here is a photo of what I’m working on now:

 

 

It’s a 17 inch round tray you put under a flower pot so it doesn’t leak when you water your plant. It’s about the cheapest thing I could find since we have to have 6 of these set ups for each of about 20 classrooms. I’ve cut up plastic grocery bags (a common plastic found in the ocean), water bottles, rubber bands (which I found don’t float), nylon string, straws, shredded plastic file folder, glitter, and more looking for the right analog of trash.

Next I’m working on what materials to have available for students to use to design and build their collection systems (we’ll encourage them to bring in their own materials too). I plan to share more about this later when we have things planned out and firmed up more. Any ideas that might help us are always welcome!

Our Annual High Altitude Balloon Project Is Coming Together

We'll launch your "High Hopes" for the world!

NOTE: If you’d like to be part of this project you and your students can send us their “High Hopes” for their school, community and the world and we will launch them up high to 100,000 feet where they will be released to slowly drift down to the ground and become one with the Earth. We’ll print your hopes on biodegradable paper designed to compost. Send your “High Hopes” here or you can tweet them to us by using the hashtag #hhpSTEM. 

We had planned on launching May 17, 2018, but somewhat unusual spring rains have made the high desert dirt roads we rely on a bit sloppy for recovery. Our current launch date is June 1, 2018, weather permitting.

This year Virginia City High School students are designing the engineering and science payloads that will reach altitudes of 80,000 to more than 100,000 feet.

Every “high hopes” launch includes payloads to carry and release the world’s high hopes that are printed out on biodegradable paper. Past designs have attempted to be mechanical in nature using a timer or altimeter to trigger a motor to spring a latch and release the “hopes.” However no group has successfully completed that kind of design, usually because of class time constraints, so they end up with a payload that relies on the chaos that ensues post balloon burst as the payloads plummet to the ground (before the parachute gets enough atmosphere to slow things down) to open flaps on the sides and release the “hopes” … which works well, but engineering motors, Arduinos, pulleys and all is intriguing, so we’ll see what happens.

Engineering payload motor driven latch release for world’s “high hopes.”

Another group is looking into gluing seeds to some of the high hopes in order to spread some flowers around the desert. They are researching what seeds they can distribute that way (don’t want to plant invasive species) and have contacted the local authorities about their idea. They are developing a water soluble glue that also might provide some nutrition for the seeds as well.

Mixing a trial batch of bio-degradable glue.

 

 

 

 

 

 

A payload designed to see how sound is effected by the thin atmosphere at high altitudes is taking on a Star Wars theme. The plan is to play the theme music from Star Wars while a camera records the image, but more importantly the sound during flight through a speaker that is insulated from vibrating the payload, so the sound must travel via the air. Does the thin air effect the sound? 

 

 

 

 

 

 

 

 

This should be an interesting payload to fly!

 

 

 

Yet another group wants to test a design to protect plants from the freezing, dry conditions they’ll encounter during the flight (actually very much like conditions on Mars). They’ve set up a group of plants to launch and a identical set to stay on the ground to compare with. They are trying several different ways to insulate the seedlings and seeds they will launch.

 

 

 

 

 

 

 

 

 

 

 

Students have also set up a social media campaign including Twitter and Instagram to ask for others to submit their high hopes. Please send us your high hopes and we will launch them high into the stratosphere!

High Hopes Launch 11/28/2017

High altitude ballooning, science and STEM

We finally managed to launch a balloon this fall. It’s been in the works for well over a month, maybe two. Weather and scheduling finally came together and we launched on Tuesday, November 28, 2017, from Virginia City High School‘s football field (in Nevada). Virginia City is best known for being home to Mark Twain, who lived, worked and wrote here in the 1860’s, the Comstock Lode gold and silver rush, as being one of the settings for the old Bonanza TV show and a rich history.

We launched about 8:30AM – it was hovering around the freezing mark and the sun was just high enough to start warming us a bit. Teacher Sarah Richardson had the honors to release the balloon after a quick countdown. Besides  3 of our GoPro cameras and various data loggers and communications gear, Sarah’s students had designed a payload to release the “high hopes” of the world we’d collected … including their own (over 700 high hopes were included in their payload) so they were intrigued to see how this whole launch thing works. The “outlooking camera” recorded this:

And the “downlooking camera” recorded this:

This launch was mostly about giving Sarah and her students some experience in how this works. The plan is now for them to design various payloads to carry out science and engineering investigations this spring … that will give them plenty of time to prepare. They designed the payload we launched by breaking into groups that each built a payload to release the high hopes which are printed out on small strips of paper. They then had trials that led to choosing the one we launched. They’ll use what they learned about payload construction and I will be visiting class to facilitate them through the process some, but most of that will fall to Sarah. Here is what the balloon burst looked like at 26,000 meters (85,000 feet) a bit less than 2 hours after launch:

In Quicktime you can play the video frame by frame which is awesome! You miss a lot in real time … besides the hunks of balloon that float by you can see high hopes fluttering through the air and one comes right at the camera and you can read it – “people everywhere” … because it is handwritten it must be one from Sarah’s class (the others were printed out) – I’m hoping we find out which student wrote it.

Folded “High Hope” with the words, “people everywhere” clearly visible – hope to find out what the rest said. About 85,000 feet, that’s Pyramid Lake in the middle of the screen shot.

I’ll be uploading some of the photos we took to Flickr when I get the chance and I’ll add a link to them.

UPDATE: Here is a link to a Flickr set of launch and recovery photos

Da Vinci Mechanics Exhibit – Machines, Engineering, “Making” and More

Inspiration for "making" in your classroom

Da Vinci A few years ago (2015) my wife and I were in Christchurch, New Zealand, and we came upon this hands-on Da Vinci Mechanics Exhibit at the Canterbury Museum.  I’d meant to share a post about it when we returned and I was reminded of that when I came across the Flickr album I had set up just the other day.

NOTE: Click on any photo in this post to enlarge it. Then you and your students can read the descriptions and see the drawings in more detail.

From the museum web site: “He studied the workings of nature’s devices and sought to recreate these as practical machines: machines for moving water, for war, for excavating, for drilling and, perhaps most famously, for flight. Exhibition highlights include the tank, the spring powered car, the hang glider, the air screw (the precursor of the helicopter) and a robotic drummer.”

What intrigued me were not only the devices themselves, but Da Vinci’s drawings that accompanied them (careful drawings of plans easily turn a STEM activity into STEAM). The fact that this was a hands-on exhibit multiplied the engagement exponentially.Da Vinci

 

Da Vinci’s designs and devices are a great model for a class engineering/making STEAM experience. What devices and the drawings and explanations that go with them could your students design? Then share them online through Flickr or a blog or wiki or video-conference or … too many ideas to list. Many more photos here.

Da Vinci

Da VinciI noted online that this is a traveling exhibit so maybe see if it is scheduled to be coming to a museum near you. And I bet students could find just a bit more about Da Vinci if they search even a bit. Please share other ideas and links to any “Da Vinci inspired” devices your students “make.”

An Eclipse by Any Other Name is an Occultation

Neptune's Moon Triton will cast shadow on Earth traveling 37,000 MPH, SOFIA plans to catch it!

 

 

I’ve been posting lately about NASA’s SOFIA flying telescope (Stratospheric Observatory For Infrared Astronomy) and its upcoming mission to catch the occultation of Neptune’s moon, Triton. NASA has posted more information about the upcoming event and I’m sharing that here including a link to resources I put together to help others understand more about why scientists are excited about this occurrence.

From NASA:

“On Oct. 5, as Triton passes in front of a faraway star it will block the star’s light in an eclipse-like event called an occultation. During the celestial alignment, the team aboard the specially equipped Boeing 747SP aircraft will make observations of the distant star’s light as it passes through Triton’s atmosphere.

Triton has not passed in front of bright stars for many years, making occultation observations difficult. Now, as Triton passes in front of a bright star, the data collected by SOFIA’s 100-inch (2.5-meter) on board telescope and three powerful instruments will enable researchers to better study and characterize the moon’s atmosphere, including its temperature, pressure and density.” 

SOFIA is a modified Boeing 747SP. Note the large opening in the side that contains a 2.5 meter (100 inch) wide reflecting telescope.

And:

“Catching Triton’s shadow as it races across Earth’s surface at more than 37,000 mph (17 km/s) while the aircraft is traveling at Mach 0.85 (approximately 652 mph), is no small feat. To ensure that they are in the right place at the right time, researchers have made advanced observations of Triton and the star with multiple telescopes to determine the location of their shadow. From these precise calculations, SOFIA’s flight planners have designed a flight plan that will put the flying observatory in the center of the shadow for approximately two minutes as Triton aligns in front of the star.”

I put together a wiki page of resources that explain the where’s and whys of this event.

SOFIA will have to fly perpendicular through the shadow (so its telescope is pointing at Triton) that is moving at 37,000 MPH while it is flying at over 600 MPH … apparently some math is involved in figuring out just where to be and when to be there to make this work!

2017 Math & Science Institute – for teachers

In New Orleans ... and it's FREE!

Earlier this year I agreed to lead two grant funded STEM professional development courses for teachers sponsored by Metairie Park Country Day School, June 7th, 8th and 9th, 2017. The courses will be held at Tulane University in New Orleans as part of the 2017 Math & Science Institute. AND NOTE THIS – You just have to get there – tuition is FREE! (note the flyer to the right for more information). Note: private school teachers have to pay $149 per course.

Each course is about 6 hours long spread over the 3 days (2 hours per day, per course). Here’s a page with all the course descriptions.

I’ll be teaching 2 courses: “Powerful, Connected, Collaborative and Global STEM Learning” and “STEM: Hands-on, Minds-on, Creativity-on” –

From the online course description:

STEM: Hands-On, Minds-On, Creativity-On is a six-hour course designed to help teachers integrate powerful STEM learning with a focus on engaging, hands-on engineering lessons. Participants will not only experience the lessons firsthand, but also how to collect and analyze the rich data the lessons produce. Strong connections to science, language arts, technology, art, the Next Generation Science Standards and three dimensional learning will be included. Most lesson activities utilize easily obtained materials.

Powerful, Connected, Collaborative, Global, STEM Learning is a six-hour course designed to allow you to see how the power of STEM inquiry projects are leveraged when students are connected and collaborate globally.

There are several Common Core State Standards that require students to utilize technology to collaborate starting in elementary school. This course will provide hands-on engineering lessons and phenomena – coupled with free or cheap collaborative online tools that promote sharing and analyzing data, explanations, global awareness and much more. Participants and their students will learn to collaborate and share through powerful writing, oral language, photography, math, art and other media. Online safety and ethics will be featured.

Check out the 2017 Math & Science Institute home page to see all the courses being offered.

Hope to see you there!

WyTECC Keynote

STEM Is A Culture, Not a Time of Day or Day of the Week

So much going on right now so my plans to blog more often have taken another hit. One of the things going on that I’m really looking forward to is my participation in the Wyoming Technology Engagement Curriculum Connection (WyTECC) in Rock Springs, Wyoming in early May. May 6th to be exact.

 

I’ll be providing the keynote and 2 to 3 breakout sessions. They asked for a “STEM-ish” theme so I’m redesigning my “STEM Is A Culture, Not a Time of Day or Day of the Week” presentation and plan to build in more STEM experiences. My sessions will focus on STEM inquiry and the important parts that get left out too often because the activity is engaging, the students get excited, time runs short and we skip the parts that really make STEM learning powerful.

Hope to see you there!

Underwater and Aerial Vehicles – Pyramid Lake Edition

It was a crisp and glorious day at Pyramid Lake...

Above: Panorama of Pyramid Lake including the Tufa formations “Stone Mother” and the Pyramid that gives the lake it’s name. Note the people on the beach between the formations for a scale of size.

Between a busy work and holiday schedule, and a bout of aggressive bronchitis, I’m late with some posts – this is one of them … and it’s an experience worth sharing! First I want to thank the Pyramid Lake Paiute Tribe for giving us special permission to visit this special and sacred part of the Pyramid Lake shore to “test drive” our OpenROV 2.8’s and fly Phantom 3 Professional aerial robots as well.

Back in October we were supposed to put the underwater robots the teachers had painstakingly assembled into the crystal clear water of Lake Tahoe to further test them and learn piloting skills. However, that day got “weathered out” by rain and high winds. The next time we could schedule a meet-up was December 3rd. It was a crisp and glorious day at Pyramid Lake. We met at the turn-off from the highway to the dirt road that leads out to the spot in the photo above. Besides the teachers having this opportunity, Trevor Galvin a math teacher at Pyramid Lake Middle and High School is part of our class and he brought along some current and past students and a few others’ students showed up as well.

Here’s how a local TV report explained the day:

The OpenROV’s have a built-in camera and the water was much clearer than we expected: 

 

 

 

Algae covered tufa formations and lake bottom.

 

 

 

 

 

 

 

 

 

 

In the bright sunlight the computer screens were hard to see, so when one of the students reported that he could see something floating in the water straight ahead we told him to take pictures  so we could see it later. Turns out it was a large sacred Cui-ui fish:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

And next another student piloted 2.8 caught a Lahontan Cutthroat Trout:

 

 

 

 

 

 

 

In the meantime Kirk Ellern was flying the Phantom 3 Professional drones the teachers had been trained in (and so were teachers and students) with the goal of photo/video archiving the experience and the area in aerial video. Kirk produced this video of the day, but more to come:


I’ll be posting more about classroom visits I’m making with the teachers in the grant from their classrooms.

Here’s a link to a Flickr album from the day.

This Low-Cost Robot Can Help You Explore the Ocean – Nat Geo Live

One of the resources we shared with teachers in the Nevada STEM Underwater and Aerial Vehicle Computer Science Institute this past weekend was this video explaining how OpenROV got its start by David Lang. It’s a “TED Talk-like” video produced by National Geographic. I especially appreciate his references to “citizen science” projects.

From the description of the video on YouTube:

“Originally interested in building an underwater robot to explore a cave rumored to have gold and treasure, 2016 National Geographic explorer David Lang and a friend had no idea where their curiosity and drive for exploration would lead them. They turned to the Internet for help building their underwater robot, and a community of people emerged to assist. With the ability to descend to a maximum depth of a hundred meters, their low-cost underwater robot, called OpenROV, is redefining ocean exploration. Hear Lang talk about the journey to build OpenROV, how it is inspiring people to explore and engage in citizen science projects, and how the latest technology is creating a wave of low-cost, do-it-yourself products that are making new forms of exploration accessible to people all over the globe.”

The video runs about 8 minutes. Enjoy!

Building our 6 OpenROV underwater robots

Teachers being messy - learning "Making" skills

The Nevada STEM Underwater and Aerial Vehicle Computer Science Institute (NSUAVCSI) was designed to provide professional development for 6th through 12th grade teachers in not only computer programming, aerial vehicles and underwater robots, but to more importantly then make those resources available to their students. My last several posts have been about our progress so far in the computer programming and aerial vehicle aspects. Now we have begun the underwater robot section of the institute.

I chose to purchase 7 OpenROV 2.8 underwater robots partly because they would have to be assembled. Many teachers have limited “making skills,” and assembly of these vehicles requires soldering, wiring, acrylic welding, gluing with epoxy, super glue, other adhesives and more. Dr. Alex Forrest from the University of California, Davis,  the lead instructor for this portion of the class, received one of the 2.8s weeks ago so he could assemble one to prepare to guide the teachers through the process. There are excellent directions online provided by OpenROV on how to build the robots, but having an experienced builder there able to share their “messy” mistakes and learning during the build has been invaluable to say the least.

Friday the 18 teachers in the institute met at the Tahoe Science Center home of the Tahoe Environmental Research Center (which is affiliated with UCD, hence Alex’s connection) to learn the science and engineering behind UAV’s, but also to begin assembling the 6 vehicles they’ll be able to check out for use with their students.

First steps involved acrylic welding the parts of the housing making sure everything was lined up and turned the correct way before making the weld … a bit nerve wracking.

After much of the welding and gluing was done and parts started to take shape it was time to begin wiring and installing circuit boards and other electronics.

Lots of gluing and wiring, but below, lots of soldering too.

This is where we left it at the end of the day Saturday. We meet next Friday and Saturday to finish building and perhaps even give them a tryout in the public swimming pool. A day at Lake Tahoe will come in October.
