The Brown Bag STEM Challenge II- Lily Pad Leap

In this challenge, students are asked to work with a partner to design a mechanism that will hold a lily pad and help a “frog” leap up to his lily pad.

Students work in pairs to construct a mechanism that will launch their frog to a specific height.  One difficulty that students encounter is that frogs must land on (and stay on) their lily pads, making this challenge um, well, challenging.  Most students design a sort of see-saw/catapult contraption, but the items provided by the teacher may frame the challenge differently.

The Brown Bag STEM Challenge design challenges focus on some key STEM concepts like critical thinking and problem solving, all while being low-cost to implement  This sequel series contains all of the same elements (design briefs, NGSS alignment, Interactive STEM Notebook pages, etc.) as the original, but with new challenges!
