Falling Objects Inquiry | Force & Motion 5E + Engineering Design
Engage your students in an exciting exploration of physics and engineering with this hands-on, inquiry-based activity all about the science of falling objects! Designed to introduce the concepts of gravity, motion, and air resistance, this 5E STEM lesson scaffolds the learning of engineering science concepts that are then applied to an engineering design challenge.
Note that this is a 5E science inquiry version of our popular Space Lander Design Challenge that dives more deeply into the science concepts behind the design challenge.
Engage: Class discusses the driving question: "If I drop two objects, will they land at the same time?"
Explore: Conduct an experiment to answer the driving question. Graph results, share with classmates, and compare data.
Explain: Connect findings to science concepts, including learning the history of human understanding of falling objects
Elaborate: Extend understanding with a Space Lander Engineering Design Challenge and STEM Career Connection.
Evaluate: Check for understanding with discussion, reflection, peer review, and a final Exit Ticket.
