Your child came home with a review sheet today for our test on Tuesday. If your child misplaced it, I have added the information below:
- When light is reflected the light hits the object and it bounces off.
- To make a shadow you need: a light source, an object, and a blocked path.
- The shadow is shortest at noon.
- Light travels in straight lines and some waves.
- When light travels from air to water it slows down and looks like it bends (think about pencil experiment).
- When a light source is blocked a shadow forms.
- Man-made light: light bulb, lantern, lamp, flashlight
- Natural light: sun, stars, firefly
- Opaque: No light passes through (examples: rock, people, wood)
- Translucent: Some light passes through (examples: tissue paper, waxed paper)
- Transparent: Light passes through (examples: glass, overhead, glasses)
- When light passes through a prism, it separates into colors.
- Think about the best color shirt to wear on a hot day and why.
