Design an Emergency Signal

Pick light, sound, or both, and test it.

Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.

What children learn in Level 42

Let's design an emergency signal! First, name the problem: who needs to know, and how far away are they?
Next, choose. Light works in noisy places. Sound works when people can't see you, like around a corner or in fog. Or use both!
Build it, then test it! Have a friend stand far away. Can they notice your signal quickly?
If they can't, make it better: louder, brighter, or flashing. Then test again.
Your turn! Put the design steps in order.
