Loud and quiet sounds, near and far

Light, sound and waves

CCSS NGSS.1-PS4-1England: KS2 Y4 Sound

Objective and success criteria

Students will: Loud and quiet sounds, near and far.

  • 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 · 6 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.
  1. What vibrates to make the sound of a recorder or flute? (the air inside the tube / the strings / your vocal cords in your throat / the cone at the front) → the air inside the tubePrompt: Which part moves back and forth when the sound is made?
  2. You pluck a guitar string and then touch it to stop it moving. What happens to the sound? (It gets louder. / Nothing changes. / It stops. / It gets higher.) → It stops.Prompt: What makes the sound in the first place?
  3. True or false? A loudspeaker makes sound by moving back and forth. (True / False) → TruePrompt: What is happening to the object when a sound is made?

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: Loud and quiet sounds, near and far. 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: Which of these sounds is the LOUDEST?
  • Step 1: From quietest to loudest:
  • Step 2: people talking < a marching drum close by < a jet plane taking off nearby
  • Step 3: So the answer is: a jet plane taking off nearby
  • Answer: a jet plane taking off nearby
  • 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.
  1. Which of these sounds is the QUIETEST? (a jet plane taking off nearby / a marching drum close by / a dog barking nearby) → a dog barking nearbyPrompt: Imagine hearing each one. Which would make you cover your ears, and which could you hardly hear?
  2. Why do teachers ask the class to stand closer during a quiet story? (Sounds travel faster to the back. / Stories are only heard by people at the front. / It makes the book bigger. / Sounds are louder when you are nearer the source.) → Sounds are louder when you are nearer the source.Prompt: How does distance change loudness?

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 8 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.
  1. True or false? Sounds get louder the further away you are. (True / False) → FalsePrompt: Think about vibration size and distance.
  2. Which of these sounds is the LOUDEST? (a dog barking nearby / people talking / a jet plane taking off nearby) → a jet plane taking off nearbyPrompt: Imagine hearing each one. Which would make you cover your ears, and which could you hardly hear?

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.
