Light Properties Investigation

Help the science team investigate what light does when it meets different materials. Use a torch in a dim room; never shine it into anyone’s eyes. Record what you observe, then explain your conclusions.

Make a Prediction

Before testing, think about how light behaves. Choose the best answer for each question.

1.In a clear space, the beam from a torch travels mostly in which way?

In straight lines
In circles
In zigzags

2.The science team points a torch at a mirror. What is the name for light bouncing off a surface?

3.Which test material is most likely to let light pass through clearly: a piece of clear plastic, thick card or a mirror?

Clear plastic
Thick card
A mirror

Test the Materials

Shine the torch at each material in turn, with white paper behind it. Keep the torch the same distance away each time. Look at how much light reaches the paper. Use the table to record your results.

Material

What I saw on the paper

Light passed through?

Clear plastic

Mirror

Thick card

4.Complete the results table. For each material, describe what you see on the paper and decide whether light passes through it.

5.The mirror sends the torch beam in a new direction. What has happened to the light?

6.A beam bends as it travels from air into clear plastic. What is this change in direction called?

Absorption
Refraction
Reflection

Explain the Evidence

Use the words reflection, refraction and absorption in your explanations where they fit.

7.The card blocks the beam and does not let light through. Some of the light is taken in by the material. What is this process called?

8.Imogen says, “The mirror absorbs all the torch light because the paper behind it stays dark.” Explain why Imogen’s conclusion is not correct.

9.Dark clothing can feel warmer than pale clothing in sunshine. Explain how absorption of light can cause this.

10.Plan a fair test to find out whether black or white paper gets warmer under a lamp. Name what you would change, what you would measure, and one thing you would keep the same.
