Activity! Try to pull the sheet of paper out from under a stack of Dominoes without having them fall. –How does this activity demonstrate Newton’s First Law of Motion? Answer: The Dominoes are at rest and will remain at rest. The paper was yanked quickly (Motion) and stayed in motion. The Dominoes did not fall because of Inertia and Newton’s First Law of Motion.

Activity Demonstration! Blast-Off –Safety Goggles Required. –Teacher breaks Alka-Seltzer into four pieces. –Teacher fills film canister ½ with water. –Teacher quickly drops in the Alka-Seltzer. tablet and snaps on film canister cap. –Teacher quickly places upside down on floor so all can see. Stand Back!

256
How did this demonstration relate to Newton’s 3 rd Law of Motion?

257
Action – Gases build in the canister until the pressure blasts the cap off. Action – Gases build in the canister until the pressure blasts the cap off.

Video! Slip n’ Fly –http://www.youtube.com/watch?v=3wAjpMP5eyohttp://www.youtube.com/watch?v=3wAjpMP5eyo –Disprove the validity of this stunt using Newtons Third Law

264
Answer: This stunt is fake because when he hits the pool the water goes up instead of in the opposite direction from the force.
