We also did electrical circuits:
- closed and open
The coolest parallel circuit was very bright. If one bulb got unscrewed the other stayed lit.
Another thing we did in science was spinner art using a little motor and 3x5 cards. We observed what blocks of colors looked like when they were spun together. Red, yellow and blue made a light pink like a kind of medicine. Red and blue made a magenta. Pink, green, and orange made orange with a purple outline. Light blue on the edges looked clear almost when it spun.
