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.

Instructional Ideas

• Invite a herpetologist to speak to the class
• Be sure to research the size of the expected eggs when designing the container in the last section

Classroom Considerations

• Requires knowledge from each of the previous lessons in the series
• Lesson is the 11th in a 12-part series

Pros

• Employs an engineering design process
• Relies on higher-level thinking skills
• Challenging and engaging activities hold scholars' interest for multiple days

Cons

• None
