Today was one of those great days when I get to work in classrooms … 3 fourth grade classes … 2 of them in the same school I visited, and 1 class 2,000 miles away. First I helped set up a “Mystery Skype” call with a class in Illinois so they could basically play the 20 questions game to figure out where each class was. Maps and questioning techniques came into play and new friends were made.
After the Skype call I stuck around and another 4th grade class joined us so we could continue their study of the atmosphere. Both classes were recently involved in the PongSat program that sends experiments to near space in ping pong balls with weather balloons. We crushed a few soda cans, which was a review for them … although they had never had an explanation as to why the cans crush … they have only been thinking and writing their ideas about what is going on.
So today to give them something else to think about – we did this:
Next students shared their thinking about the science behind what happened, and then I led a discussion using their ideas to get them to a better understanding. Then the teachers had me show them a video of a high altitude balloon bursting from the air pressure and asked them to explain how that was related. All in all a great experience.
Learning is messy!
