Sound comes from vibrations
Light, sound and waves
CCSS NGSS.1-PS4-1England: KS2 Y4 Sound
Objective and success criteria
Students will: Sound comes from vibrations.
- 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: no earlier skill in the map; start from what students know.
Leads to: Pitch and loudness; Speed of sound and echoes; Find the part that vibrates to make the sound
Materials: Slinky or rope, Mirrors and torches, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 6 min
- Quick retrieval: three short questions students should already manage. Answers on mini whiteboards.
- Show answers together and note who needs support in the main task.
- When you speak, what vibrates to make the sound? (your vocal cords in your throat / your eyes / your hair / your teeth) → your vocal cords in your throatPrompt: Put your fingers on your throat and hum.
- Sound: which statement is true? (Sound cannot travel through water. / Sounds are made by vibrations. / Sound travels through space between planets. / Loud sounds do not involve vibrations.) → Sounds are made by vibrations.Prompt: Can sound travel where there is nothing at all?
- Sound: which statement is NOT true? (Sound cannot travel through empty space (a vacuum). / Sounds are made by vibrations. / Sound can travel through solids, liquids and gases. / Sound travels through space between planets.) → Sound travels through space between planets.Prompt: Can sound travel where there is nothing at all?
Hook · 6 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 comes from vibrations. Read the success criteria together.
I do: model it · 12 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: How does sound reach your ears?
- Step 1: Vibrations pass from particle to particle through the air to your eardrum.
- Step 2: So the answer is: Vibrations travel through the air to your ears
- Answer: Vibrations travel through the air to your ears
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 12 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- How does sound reach your ears? (It does not need to travel / Your ears pull the sound in / Vibrations travel through the air to your ears / Sound travels as light) → Vibrations travel through the air to your earsPrompt: Sound needs something to travel through.
- Sound: which statement is true? (Sound cannot travel through empty space (a vacuum). / Sound cannot travel through water. / Sound travels through space between planets. / Loud sounds do not involve vibrations.) → Sound cannot travel through empty space (a vacuum).Prompt: Can sound travel where there is nothing at all?
You do: independent practice · 17 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 6 questions are on the student sheet below, with answers in the key.
Exit ticket · 7 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Sound: which statement is true? (Sound travels through space between planets. / Sound cannot travel through water. / Loud sounds do not involve vibrations. / Sounds get fainter as you move further from the source.) → Sounds get fainter as you move further from the source.Prompt: Can sound travel where there is nothing at all?
- Rice grains on a drum jump when the drum is hit. What does this show? (The drum is magnetic / The rice is alive / Sound is made of rice / The drum skin is vibrating) → The drum skin is vibratingPrompt: What makes the rice move?
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
- 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
- Move on to: Pitch and loudness; Speed of sound and echoes; Find the part that vibrates to make the sound.
- 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.
