Properties of Sound Waves

Lab Brief #3

🎯 Your mission

Learn the rule. Then catch nature using it.

⚡ The twist

Nature loves to surprise the careful watcher.

What you'll learn

Sound waves have properties including amplitude (loudness), frequency (pitch), and wavelength. Higher frequency means higher pitch. Greater amplitude means louder sound.

Key words

wavelength
The distance from one wave crest to the next.
frequency
How many waves or vibrations happen each second.
amplitude
How tall a wave is, measured from its middle to its top.

Make a hypothesis first

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

Say your guess out loud — then find out if you were right.

Step 1 of 3 · Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 of 3 · Observe

Note any unexpected results and think about why they happened.

Step 3 of 3 · Record

Share your findings with the class or a partner and discuss what you learned.

Mind = blown

🔬 The more you look, the more nature shows you.

Nice work!

You got 0 of 3 right.
