May Be The Force Be With You ?
The 3rd law says that for every action (force) there is an equal and opposite reaction(force). Forces are found in pairs. This law I found to be the most interesting. Upon further research after watching the video,I found some other examples that I feel would work well in a classroom setting. #1 Sitting in a chair. Your body exerts a force downward and that chair needs to exert an equal force upward or the chair will collapse. This is ideal for students who sit at their desks in the classroom! An easy concept for them to grasp. #2 Shooting a cannonball. When the cannonball is fired through the air(by the explosion) , the cannon is pushed backward. This example works excellent when incorporating science with social studies.I also feel that Title will be a great hook to get the children excited about learning all 3 of Newton's Laws.

Newton's 2nd Law
The 2nd law says that the acceleration of an object produced by a net(total) applied force is directly related to the magnitude of the force, the same direction as the force and inversely related to the mass of the object.!!! This law I find to be confusing especially when you see the formula F=ma A=f/m. However,as I watched the videos that showed the spaceshiips,soccer balls, balloons and cars I remembered working on some of these activities during the 2009 PISA Institute workshop with Carol Sheilds(and Augusto).Doing those activities DID make it much easier to understand. Therefore, I have confidence that my students will feel the same.

Furst Law Force and Motion
The first law says that an object at rest tends to stay at rest,and an object in motion tends to stay in motion,with the same direction and speed.A good example of this idea was the astronauts. You noticed that the tools float.They can just place them in space and they stay in one place. There is no interfering force to cause this situation to change. Showing the students this video, as well as the coin trick and dishes video, will encourage the childrern to use hands on experiments to further understand Newton's First Law. I know I enjoyed doing these myself and they certainly improved my knowledge.
