Newton's Third Law
This tutorial was a bit easier to follow than the second. Newton's Third Law might be easier to teach to third graders than the second law although some of the concepts will not be easy to get through to them. I liked a lot of the activities that I can do to show them that for every action, there is an equal and opposite reaction. They would definitely have the misconceptions about the more mass of an object, the amount of force exerted on another object, and the reactions. Doing the actual physical activities to explain this law would be fun for them but also help with the explanation of the concept. It surely did for me!

Newton's Second Law
This tutorial was a little more difficult to follow that the first. The concept will be harder to teach third graders, but using some of the activities will definitely help. A good activity to start with would be the ping pong ball force/acceleration activity. Simple and to the point. I would like to try this with different size balls and applying different forces. I will have students name objects with different masses so they understand this concept. The balloon rocket activity is a neat thing to do to show acceleration. They will actually be learning something while they are having fun!

Newton's First Law
Physical Science is definitely not my strong point, but this tutorial definitely helped me better understand Newton's First Law. The activities are simple and easy to use in my third grade classroom. I especially like the curved track and marble activity. I would hope that my students would eventually understand Newton's Law when doing this activity. The friction activity is another one that is great for young students to do to understand how an unbalanced force affects the motion of an object. Using these activities will make me more comfortable in teaching this concept!
