LESSON OUTLINE

5min Students complete the Do Now by selecting the best design.

5min Designs are reviewed for completion. If not complete, students must finish before continuing.

10min Students gather materials and construct Egg extractor.

5min Students test Egg extractor. If not successful, students must redesign before attempting again.

5min Clean up. Wrap up.

AIM: Students will build an egg extractor using common inexpensive materials by first asking questions, imagining solutions and problems, planning their design, constructing their device, and refining their design for improved results.
