1. INTRO TO LIGHT

2. Learning Scale 4 – Design an experiment to show how waves move at different speeds through different materials. 3 – Explain why waves move at different speeds through different materials. 2 – Recall the terms: reflection, refraction, crest, trough, amplitude, wavelength, & frequency 1 - Identify types of waves.

3. What is light? Light is an electromagnetic wave which means that it can travel through empty space.

4. Light & Matter Opaque – material through which no light passes Translucent – a material that allows most light to pass through and form a blurry image. Transparent – a material that allows almost all the light to pass through and form a clear image.

5. Light & Color Pigments Primary Secondary Magenta Blue Yellow Green Cyan Red Combined = black Light Primary Secondary Green Magenta Blue Yellow Red Cyan Combined = white

6. Reflection The bouncing of a wave off a surface.

7. Refraction

8. Transmission

9. Absorption

10. Diffraction

11. Knowledge Check Describe 3 things that can happen when light strikes an object. Compare and contrast an opaque and transparent object.
