I am an inclusion teacher and the best way to explain Newton's Third Law according to me is "If you push something it will push back".

5 Making Newton's Second Law more understandable
NSTA used a tutorial of 3 space ships to show F=ma. The spaceships had different masses and forces. Our challenge was to make all the spaceships move at the same speed. In order to make the spaceships move at the same speed, the force and mass had to be equal. I would use the ping pong ball and golf ball activity suggested to explain the concept easily to my students, since I don’t have the spaceships available.

5 Tug of War
I loved the way the NSTA tutorial explained net force/unbalanced force. If two people are pulling on a rope with the same amount of force, or pushing an object with the same amount of force it will not move. The NSTA explained it in a way that I will be able to model it, so my students will understand the concept.
