Week 01 · Monday: Feel the Sound (Science Launch G1)

Monday: Can sound shake things?

Rocket taps a pot lid with a spoon. Bong!

Raven asks, "What do you notice?"

Nova hovers close. "Touch the lid," she says. "Can you feel it?"

Tap a pot lid, and the lid shakes.

The shake is very small and very fast.

Shaking back and forth very fast is called vibrating.

The lid vibrates, and it pushes on the air.

The air shakes too, all the way to your ears.

Inside each ear is a thin part called the eardrum.

Shaking air comes into your ear.

The shaking air makes your eardrum vibrate.

Then you hear the sound!

So sound can make things vibrate, like your eardrum.

SOUND AND SHAKING

What does a pot lid do when you tap it?

What part inside your ear shakes when sound comes in?

What does vibrate mean?

Sentence	True or false?
Sound can make your eardrum vibrate.	?
A tapped pot lid stays very still.	?
Shaking air can travel to your ears.	?

WHY THIS EXERCISESound is shaking, and sound makes things vibrate.

Try it

Ask a grown-up to tap a pot lid gently.
Touch the lid with one finger.
Can you feel a tiny buzz?

FOLLOW THE SHAKE

The lid vibrates. What does it push on next?

Where does the shaking air go?

Is the shake of a lid big and slow?

What did Nova tell Rocket to do?

Sentence	True or false?
The eardrum is a thin part inside your ear.	?
You hear when your eardrum vibrates.	?
The shake of a tapped lid is slow and huge.	?
A vibrating lid pushes on the air.	?

WHY THIS EXERCISESound travels as shaking from the lid to your ear.

Draw a pot lid, wavy air and an ear.

Here are new sight words.

Look at each word. Say it. Spell it.
