Grade 4 Science · World 6: Light Lab · Level 38
Opaque, Transparent, Translucent
Classify materials by how much light passes through.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 38
- Welcome to the Light Lab! Scientists sort materials by how much light gets through them. Let's shine a flashlight at a few.
- Transparent materials let almost all the light through. You can see clearly through clear glass.
- Translucent materials let some light through, but it scatters. Wax paper glows, and things behind it look blurry.
- Opaque materials let no light through. Cardboard blocks the beam and makes a dark shadow.
- Try it with a grown-up: in a dark room, shine a flashlight at different materials. Keep the flashlight and the wall in the same spots, so your test is fair. Never shine it into anyone's eyes.
Georgia Standards of Excellence in Science:
- S4P1.a — Plan and carry out investigations to observe and record how light interacts with various materials to classify them as opaque, transparent, or translucent.
