4th Grade in the STEM Lab: Problem Solving with Simple Machines

Blog by Mr. Misch:

The fourth grade students face a big problem this month: they need to construct a factory sub-system consisting of three simple machines. The sub-system needs to move a bag of potatoes off of a potato chip factory floor to the assembly line with as little force as possible. To help solve the problem, the fourth graders have been busy studying the simple machines they can use. Good luck fourth graders!
