Today we started a lab where the kids investigate the effects of radiant energy. They get to use radiometers and they clearly think they are pretty cool. They started out by observing how the radiometers behaved in different types of light and at different distances from those lights.

| Once the radiometers start spinning, apparently it becomes mesmerizing. . .almost hypnotic |

| So. . .how does the distance from the clamp lamp to the radiometer affect the amount of time the radiometer vane spins? Your thoughts? |
