How Your Ears Hear (Part 5)

๐ŸงชLab Brief #83

Information Processing.

๐ŸŽฏ Your mission

Predict it first. Then prove yourself right (or wrong).

โšก The twist

Nature loves to surprise the careful watcher.

๐Ÿคฏ

Mind = Blown

๐Ÿ”ฌ The more you look, the more nature shows you.

๐Ÿ”ฎ

Make a hypothesis first

Before you start: write down what you think will happen, and why.

What You'll Learn

Ears detect sound waves that vibrate the eardrum. Tiny bones in the middle ear amplify vibrations, and the cochlea in the inner ear converts them into nerve signals.

Key Words

  • skeleton
  • muscle
  • nerve

Materials Needed

  • different scented items
  • textured objects
  • timer

Safety First

  • Be careful with scissors โ€” ask an adult for help if needed.
  • Do not look directly at the sun or bright lights.
