Light helps us see! Try these experiments:
| Object | Light goes through? (Yes/Some/No) | You can see through it? |
|---|---|---|
| Window glass | ||
| Wax paper | ||
| Cardboard | ||
| Plastic wrap | ||
| Aluminum foil | ||
| A hand |

Compare light and sound:
| Light | Sound | |
|---|---|---|
| Can you see it? | ||
| Can you hear it? | ||
| Does it travel? | ||
| Can you block it? |
