Light and Sound Exploration
Forces, Motion, Light, and Sound — Investigating how light and sound work
๐Ÿ“ Directions: Do experiments to discover how light travels through objects and how sound is made!
Part A: Light Exploration

Light helps us see! Try these experiments:

ObjectLight goes through?
(Yes/Some/No)
You can see through it?
Window glass
Wax paper
Cardboard
Plastic wrap
Aluminum foil
A hand

What I learned: Light goes through some things but not others because

Part B: Sound Exploration

Sounds are made when things vibrate (shake very fast)! Try these:

  1. Put your hand on your throat and hum. What do you feel? _______________
  2. Pluck a rubber band. What do you see? What do you hear?
  3. Tap a desk softly, then hard. How does the sound change?
  4. Cover your ears. Is the sound louder or softer? _______________
Part C: Sound vs. Light

Compare light and sound:

LightSound
Can you see it?
Can you hear it?
Does it travel?
Can you block it?
