Brightness vs. Distance lab part 1
After seeing some demonstrations and explanations of inverse square relationships,
we will design a lab experiment to measure the brightness of a small light source as a function of distance. You will get information about the inverse square law, which teaches us that the brightness of light is inversely proportional to the square of the distance to the source. After designing the lab we will look for equipment to set up the measurement.

If the earth's magnetic field flips, lots of wierd things would happen. See the sidebar on this article for some speculation on this idea.

Leap seconds; Rocks
Leap seconds;
Basic introduction to the types of rocks. Igneous, Sedimentary, and Metamorphic. The rock cycle.
After we take some notes, we're going to do an investigation on the channels cut into the hillside at the athletic field due to the recent heavy rains. We will measure angle of incline, depth and width of channels, and take pictures and make sketches of the channels.

Stream table experiments... we may do some of these. We have stream tables, and sand left over from our cratering labs.
