The Ice Pop Challenge

     On Friday, we completed our PLTW unit on matter with "The Ice Pop Challenge". The kids were to use what they've learned to design and build something to keep their ice pop from melting. After working with a small group to finalize an idea, they began building. The pops were then placed in the design and put under the heat lamp for 30 minutes. We then took them out and measured how much of their pop had melted. We came to the conclusion that surrounding the pop with packing peanuts ( or nuts as second graders call them) worked pretty well. Here are some fun pictures of the process.
