HS, Astronomy Std 37: Define Radio Astronomy and explain how radio telescopes work.

Lesson Plans: See inside a closed box Radar is a kind of light energy, but we can't see it. It also acts like sound, because it bounces off surfaces making "echoes," which are "heard" by the radar antenna. This activity shows how radiowaves can be used to get a picture. Solar Storms and You Students will calculate the ending percentage of radio wave strength at the receiving station. Distance Measures This exercise demonstrates three of the major distance measuring techniques: radar, parallax, and "standard candles" (both linear size and luminosity).
