Reflection: Checks for Understanding Energy Transfer: Engineering Catapults - Section 8: Closure: Connecting Catapults to Kinetic and Potential Energy


It can be easy in the business of the class period to "skip out" on the closure of a lesson.  I know for me there are times that I just want to give the students those last 5 - 10 minutes to build and test.  However, without stopping to check for understanding, you cannot be sure students are actually connecting to the ideas you want them to.  As adults and scientists, the connection between potential and kinetic energy and energy conservation are clear in this activity, but without stopping to ask the students can make those same connections, man of them simply won't.  Over the course of the course of these days of designing and launching, take time to stop to check for understanding of the science content this lesson is designed to address.

Energy Transfer: Engineering Catapults

Unit 5: Energy
Lesson 3 of 11

Objective: The student will be able to describe and model situations in which different amounts of potential energy are stored in a system and support the claim that when the kinetic energy of an object changes, that energy has been transferred to or from the objects in the system.

Big Idea: Students use their understanding of kinetic and potential energy to design catapults using easily accessible materials that launch marshmallows!
