Light sources and seeing
Light, sound and waves
CCSS NGSS.1-PS4-2CCSS NGSS.4-PS4-2England: KS2 Y3 Light
Objective and success criteria
Students will: Light sources and seeing.
- 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: Shadows and transparent, translucent and opaque materials; Reflection of light; Why we need light to see things
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.
- Is lightning a light source? (light source / not a light source (reflects light)) → light sourcePrompt: Does it make its own light, or does light bounce off it?
- In which direction does light travel from a source? (in straight lines / only upwards / in zigzags / in circles) → in straight linesPrompt: Think of a torch beam in a dusty room.
- Light: which statement is NOT true? (Light travels in straight lines. / The Sun is a light source. / The Moon is a light source. / The Moon shines by reflecting sunlight.) → The Moon is a light source.Prompt: Does the Moon make its own light?
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: Light sources and seeing. 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: Is a cat's eyes at night a light source?
- Step 1: These do not make light; we see them because light bounces off them.
- Step 2: So the answer is: not a light source (reflects light)
- Answer: not a light source (reflects light)
- 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.
- Is the Moon a light source? (light source / not a light source (reflects light)) → not a light source (reflects light)Prompt: Does it make its own light, or does light bounce off it?
- In which direction does light travel from a source? (only upwards / in zigzags / in straight lines / in circles) → in straight linesPrompt: Think of a torch beam in a dusty room.
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.
- Light: which statement is NOT true? (We see objects when light reflects off them into our eyes. / The Moon shines by reflecting sunlight. / The Sun is a light source. / A mirror is a light source.) → A mirror is a light source.Prompt: Does the Moon make its own light?
- Is the Sun a light source? (light source / not a light source (reflects light)) → light sourcePrompt: Does it make its own light, or does light bounce off it?
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: Shadows and transparent, translucent and opaque materials; Reflection of light; Why we need light to see things.
- 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.
