Or why I teach it!
This experiment touches on the G word that Sir Isaac Newton wrote about during the bubonic plague, GRAVITY. This is a great hypothesis-observation-test-conclusion activity. The website has clear instruction and touches upon some outstanding science facts.
I wish there was more visual aids on the resource like videos or pictures. That being said, this is a classic experiment that will take about ten minutes to create and discuss. I’d recommend this activity for anyone who wants to use the force; no not that one!
