Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations. Also, learners design and build their lander within a pre-determined budget to help reinforce a real-world design scenario. Materials list can be expanded to include a great variety of items as desired.
