More expansive version of the types of light energies and the "invisible colors" on the light spectrum that we cannot see and how our brain creates them. Read complete article and then do experiment labeled "The Black Sheep In The Grey Area: The Chimerical Colors"

This link explains how a kaleidoscope works. You can use the link below labeled Light reflection to make your own kaleidoscope and then explain the science behind it using this link.

Make a kaleidoscope as a fun activity and to talk about how light reflects. This is a link to a how to page. I am also posting another link that explains the science of a kaleidoscope.

This is a Mystery Doug Video lesson that is similar to activity 2 in the curriculum. What my son liked is it includes a video about rainbows and walks the child through the investigation. You can set up a free account and access this video.

Ellen McHenry has free printable Bentham disks to use for the spinning disk project. Her handout includes a little info on the way eyes see color as well.

We followed up the experiments on materials that absorb, reflect, and transmit light by asking what happens to materials that absorb light. We put out two sheets of paper in the sun, one white and one black. We put a thermometer on each, and saw that the black sheet had a higher temperature after several minutes.

I had my son used what he had learned to design a solar oven using a pizza box, but instead of giving him instructions, I walked him through designing it himself. I asked him to come up with materials to absorb light (for the inside of the box), reflect light (for the top flap), and transmit light and then trap it and convert it into heat energy inside the oven. It was very successful. I suggest adding a cheap oven thermometer so you can see the temperature the oven gets up to. We made s'mores.

We struggled to get our color wheel spinning fast enough until we attached it to a drill with a paper clip. The white really showed through when we got the drill to high speeds.
