Second Law Review
As I read the tutorial I noticed that the second law of motion is a bit more complicated than the first law of motion. F=ma is not easily understood no matter how it is explained. Finding the acceleration is confusing to me. The interactive simulations did help me to understand easier. I liked the link at the end of classroom resources. This will definitely come in handy for me with my students. My students would especially enjoy the balloon and aluminum can activity. I plan to demonstrate this to my class. I may go back and read the tutorial again for a better understanding. The author couldn't have put it in simpler terms, therefore; a second read would be beneficial to me!

Third Law Explained
The information presented in the article, Force and Motion: Newton's Third Law was very thorough. Everything you wanted to know about the science theory is presented with easy to read informational text and pop up simulations. One aspect of the article that is helpful is the subheading: common misconceptions. In particular, the author advises rephrasing of the words in the third law to emphasize that the forces applied are equal. The examples provided helped further explain the concept.

First Law Explained
If you asked me what Newton's First Law was I would be able to recite what I think most people would say..."An object at rest..."however, my understanding of the scientific theory behind the law was limited to rote memorization. Reading the informative article, Force and Motion: Newton's First Law, I was able to connect the theory to real life examples. The hands on activities were excellent for students and the accessible lesson plans make incorporating these activities that much easier.
