In these activities, students use mirrors to discover how light reflects and how images form. How we see certain objects depends on how the surrounding light rays interact with them. Light can be reflected, refracted or absorbed. We can use mirrors to explain the properties of reflected light and the resulting images.
How are rainbows made? What makes grass green and jeans blue? How do sunglasses work? In this series of demonstrations and activities, students will explore how colours are created and understood by our brain.
Black Light? Sounds like an oxymoron, doesn’t it? Light is a wave of energy and not all wavelengths are visible to the human eye. Black light emits very little visible light, but has an interesting effect of making certain colours glow, or fluoresce. In this unit, students investigate black lights and explore the difference between fluorescent and phosphorescent items.
