🔍 Part 1: Observation and Investigation

1. Pencil in Water Experiment - What did you observe?

Draw what you saw when the pencil was placed in the glass of water:

2. Describe in your own words what happened to the pencil's appearance:

3. Why do you think this happened? (Hint: Think about light travelling from water to air)

🪞 Part 2: Mirror Reflection

4. When light hits a mirror, what happens to it?

It disappears

It bounces back (reflects)

It goes through the mirror

It changes colour

5. Draw a ray diagram showing light reflecting off a mirror. Include the incoming light ray and the reflected light ray:

6. Complete this important rule about reflection:

The angle of incidence _________ the angle of reflection.

7. What did you notice about the angles when you shone the torch at the mirror?

8. Match the scientific terms to their meanings:

Refraction

Reflection

Angle of incidence

Light bouncing off a surface

Light bending when it moves between materials

The angle at which light hits a surface

9. Give one real-life example where you might see refraction:

10. Give one real-life example where you might see reflection:

11. As a confident young scientist, explain to a mate how light behaves differently in water compared to air:
