Light and Sound Mad Science:  This class is all about waves! We compare the properties of visible light to the properties of other types of electromagnetic radiation. We explore the relationship between frequency and colour (in light) and frequency and pitch (in sound). Tying this all together, students will get a chance to "see" the vibrations made by their own voices.  For grades 3 to 6. Registration is required. Saturday August 5th @ 2:30-3:30
