Turn on a light and watch what happens! Tap the clues and open all four locks to learn about light and shadows.
We need light to see. When something blocks the light, it makes a dark shadow. Tap each clue, then open all four locks!
Tap each clue to see it. You can open them again anytime.
Use the clues to open each lock.
You learned that we need light to see, and that blocking light makes a shadow. Now go make some shadows of your own!
