To explain all of what happened today I would have to take you through all the things we have learned so far. There have been experiments and radiometers and thermometers and lots of discussion about heat. So today when we pulled a Solar Bag out to try on the basketball court, no one but Grade 3 was ready for what it would show us.
Our question: What will happen to the long black plastic bag if we unravel it, put air inside it, and gather the sun’s energy?
The answer lies in the results- but another question remains: Why? While you ponder, check out these real life results!
