In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

Learners build simple catapults and use them to launch cotton balls.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.
