In December, we did an experiment on transparent, translucent and opaque materials.
What you need:
- Torch
- Mini whiteboard
- Lots of different materials
What to do:
1. Turn on torch and point it at the board.
2. Put a piece of material about half way between the torch and the mini whiteboard.
3. Check if any light comes through the material.
What should happen:
- If the light can’t go through the material, it is opaque.
- If a little bit of light goes through the material, it is translucent.
- If all the light goes through the material, it is transparent.
Normal results:
1. Tissue paper (Translucent)
2. Bubble wrap (Transparent)
3. Cardboard (Opaque)
4. Cling film (Transparent)
5.Tim foil (Opaque)
6. Baking paper (Translucent)
