Force and Energy

Second grade physicists investigated Isaac Newton’s laws of motion with a high energy lab!

What will happen to the ball if I knock the side of the pie plate? Why?

How is it possible to pull the tablecloth off the table without the dishes falling on the floor? Try this at home! Click here to learn more.











We moved to the lab tables and applied our knowledge of the laws of motion to knock the pennies in the cup (Click here.) and the hex nut inside the bottle without touching either.





















Second grade experienced the cobra weave as an introduction to potential and kinetic energy.

They further explored potential and kinetic energy with cyclone flyers, boinks and dropper poppers. I introduced the concept that there are different kinds of potential energy: elastic, gravitational, and chemical.
