Rated 4 out of 5 by from good, simple product; okay price I bought the radiometer to augment my 6th grade science unit on solar energy. It's a great, simple demonstration of the principle of black absorbing heat, and white reflecting heat. I have used the demonstration showing that a fan (or cool hair dryer) won't make a difference, but a heat lamp will. There's not much else to the radiometer than that. It does make a nice classroom display on the window sill, though -- especially on a hot, sunny day!

Rated 5 out of 5 by from Super way to explore solar energy I have eight of these so my students can work in small groups and observe them close up. I like how they work on the atomic level. They work great indoors under normal light and fantastic outdoors in the sun.
