- Doppler radar is a key forecasting tool - Find out how the doppler effect is used to read the weather, and how it can be used in short term weather prediction.
www.usatoday.com/weather/wdoppler.htm
- How Ultrasound Works - Learn about how waves are reflected as they travel through various objects, and how these reflections are used to produce images for medical use.
www.explorescience.com/activities/Activity_page.cfm?ActivityID=43
- Investigating Sound - Explains what is sound, how we hear it, and shows the features of a sound wave graph.
