'What does sound look like?' is a clip that teachers can shown students. The middle section is extremely technical and teachers may want to fast forward through it. It is, in my opinion, well worth viewing.
2. Sound Waves - a brief explanation.
Go to the website and complete 'Do you hear what I hear?'
Sound waves hit the eardrum and rattle little bones. The bones push fluid onto ear hairs that decipher the sound into electrical pulses that our brains can interpret.
When the vibrations are fast, you hear a high note. When the vibrations are slow, it creates a low note.
Hitting hard with a hammer makes a very high, sharp sound that compresses the air molecules and makes a very tight, jagged wave.
Banging a tuning fork makes a low, soft sound that that compresses the air molecules loosely and makes an even, softer wave than the hammer.

3. Sound Stories
A sound story uses only sound effects to tell a story. Each of these short stories have told their tale using only 5 sounds.
Listen to the three sound stories.
Tell a friend who has finished what you think eact story is about.
Bonus for early finishers: Using scrap paper, can you make a list of the sounds you heard in each one.
