Light
By Lisa in FL

Hi Jennie,

I'm doing a unit on Light and Sound for 4th grade next month. We aren't getting into heat much. Here are some of the things that I'm doing for light:

*using prisms and a white sheet of paper to discover how
white light breaks up into colors.(outside, & you need a sunny day) I'm trying to get one prism for each group of 4.
*shining light from a flashlight through different filters (colored cellophane in layers workds) onto colored construction paper to find out what colors it makes
*using rope to demonstrate a light wave's motion (energy waves are in our 4th grade state expectations,

it's probably a little advanced for 3rd)

*learning translucent, transparent, and opaque using wax paper, plastic wrap, and aluminum foil

*experimenting with curved mirrors-- I have a little bendable one that came with a science kit to see how light reflects in different directions

*finding out uses for lenses -- I'm taking in a pair of glasses, a microscope, a picture of a telescope, a magnifying glass, a camera, and other things that use lenses for the kids to look at, look through, etc. We're not going into convex or concave, I'm leaving that for their middle school science teacher.

If you have a local teacher store, go ask the person there. I have a TON of books w/ really good stuff. I could spend months on this!

Check the directory on this site, and also www.askeric.org, for lesson plans.

Hope this helps! E-mail me if you'd like the titles of the books I have (I don't have them with me right now)
