Chemical Reactions and Engineering Design

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach the proper temperature range, additional reactions to inflate a bag and cushion the egg, and how to design a carrier for moving the egg to a conservation center. Lesson is the 11th in a 12-part series.
