Light & Seeing in the Dark
Science · Waves, Light & Sound · conceptual
Observe that objects in darkness can be seen only when illuminated by a light source
What mastery looks like
- Explain that we need light to see objects — without any light source, it is completely dark
- Describe an observation showing objects become visible only when light reaches them
- Distinguish between light sources (sun, torch, lamp) and objects that just reflect light
Check your understanding
If you go into a completely dark room with Light & Seeing in the Dark, can they explain why they can't see anything until a torch is switched on?
