Grade 4 Science · World 6: Light Lab · Level 40
Mirrors and Reflection
Predict where light goes after it bounces off a mirror at different angles.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 40
- When light hits a smooth, shiny mirror, it bounces off. That bounce is called reflection.
- Look at the angles. The beam comes in slanted and leaves slanted by the same amount, like a ball bouncing off the floor.
- Change the angle, and the bounce changes too. A steeper beam leaves steeper.
- Shine straight at a mirror, and the light comes straight back.
- Tilt a mirror, and you can send light around a corner! Try it with a grown-up, using a flashlight and a small mirror. Never aim the light at anyone's eyes.
Georgia Standards of Excellence in Science:
- S4P1.b — Plan and carry out investigations to describe the path light travels from a light source to a mirror and how it is reflected by the mirror using different angles.
