Sound can make things vibrate
Light, sound and waves
CCSS NGSS.1-PS4-1England: KS2 Y4 Sound
Objective and success criteria
Students will: Sound can make things vibrate.
- I can answer questions on today's skill on my own, without help.
- I can explain each step and say why it works.
- I can check my answer and spot a mistake.
Before and after
Needs first: Find the part that vibrates to make the sound
Leads to: the next skill in this area.
Materials: Slinky or rope, Mirrors and torches, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 5 min
- Quick retrieval from earlier learning (Find the part that vibrates to make the sound). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- What vibrates to make the sound of a voice? (the metal triangle / the strings / your vocal cords in your throat / the stretched skin on top) → your vocal cords in your throatPrompt: Which part moves back and forth when the sound is made?
- You pluck a guitar string and then touch it to stop it moving. What happens to the sound? (It gets louder. / It gets higher. / It stops. / Nothing changes.) → It stops.Prompt: What makes the sound in the first place?
- True or false? A drum makes sound even when nothing hits it. (True / False) → FalsePrompt: What is happening to the object when a sound is made?
Hook · 5 min
- Ask the class to make a wave with a rope or slinky and describe what moves and what doesn't.
- Share the objective: Sound can make things vibrate. Read the success criteria together.
I do: model it · 10 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: A tuning fork is struck and then dipped into a bowl of water. What do you see?
- Step 1: The vibrating fork shakes the water, showing that sound is vibration.
- Step 2: So the answer is: The water splashes and ripples.
- Answer: The water splashes and ripples.
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 10 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- When a very loud lorry (truck) goes past, the windows rattle. Why? (The lorry touches the windows. / The windows are making the noise first. / The loud sound makes the glass vibrate. / The windows are scared.) → The loud sound makes the glass vibrate.Prompt: Sound carries vibrations from the lorry to the house.
- True or false? We hear because sound makes parts inside our ears vibrate. (True / False) → TruePrompt: How does sound get from one place to another?
You do: independent practice · 10 min
- Students work on the student sheet. Circulate and check the first two answers of every student early.
- Students who finish: write a question of their own for a partner, with the answer.
The 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 5 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Sound and vibration: which statement is true? (Rice on a drum jumps because of the light in the room. / A string telephone works because vibrations travel along the string. / Sound can only travel through air. / A string telephone works best with the string loose and floppy.) → A string telephone works because vibrations travel along the string.Prompt: Sound is a shaking that passes from thing to thing.
- True or false? Only things you touch can be made to vibrate. (True / False) → FalsePrompt: How does sound get from one place to another?
Watch out for
- Everyday meanings of words getting in the way of the science meaning: define key words explicitly.
- Remembering facts without the reason: ask "why?" and "what is the evidence?"
Support and stretch
Support
- Review first: Find the part that vibrates to make the sound.
- Use concrete materials: slinky or rope.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Explain a common mistake in writing and how to fix it.
- Write a word problem that uses today's skill, then solve a partner's.
