Force and Motion

Great review for Newton's laws!

If you've read the book from the Stop Faking It Series "Force and Motion," you can tell Dr. Robertson had a hand in developing this SciPack. The information is both accessible and at times quite funny. I appreciate how the SciPack gets at the points of Force and Motion without getting lost in minutiae and come away from this experience with a solid understanding of Newton's laws. Highly recommended for any teacher looking at teaching this subject (which I believe can be taught at any grade level). Nicely done!

Didn't know that...

I had wondered about the answer to the question before, but never took the time to research the nuts and bolts on my own. Robertson does a great job of making the concept of frequency, as it relates to radio and cell phone signal, understandable. I liked the hands on experiment as well. I now will be able to demonstrate and explain the reasoning of this concept to my family as we drive long distances. I'm sure they can't wait!
