[|**Intro to Electricity and Magnetism**] This interactive activity from ExploreScience covers topics such as static electricity, current, resistance, conductors, circuits, magnetism, the relationship between electricity and magnetism, and how generators work.

[|**The Electricity Book: Part 2**] This interactive lesson teaches all about how electricity moves through a circuit to light a bulb. Great animations and explanations make the information clear.

What about our galaxy in relation to other galaxies? This impressive flash animation helps put the size of the universe into perspective. Using the powers of 10, this animation, based on the book "The Powers of Ten," allows you to see how large our universe really is. The beginning frame also offers an excellent discussion of exponents.

=== [|Distance and Displacement] ===  Check out this **video** for a review of scalars and vectors (distance, displacement, speed and velocity): [|__http://www.khanacademy.org/video/introduction-to-vectors-and-scalars?playlist=Physics__]

For example, the distance from WHS to Cold Stone Creamery is 1.8 miles but the magnitude of the displacement is only 1.3 miles! Yum!
 * Activity**: Go to the following website ( [|__http://www.usatf.org/routes/map/__] ) and figure out the distance and the magnitude of displacement from Westerly High School to your home or your favorite place in Westerly!


 * Remember**:
 * Distance** is the length of the path between two points.
 * Displacement** is the direction from the starting point and the length of a straight line from the starting point to the ending point.
