1. There are several good activities that you could try here.

You could draw around the shadows of a couple of children in the playground using chalk. Don’t forget to draw around their feet too, so that they can stand in exactly the same place when you return an hour or so later. Notice how the shadows have changed - moved and lengthened or shortened. Note the position of the Sun when you first go out and check again when you return. How is this related to your shadow?

Worksheet C9 (G) can be used to record the children’s observations.

Stick measured lengths of paper on the classroom window and measure the shadow on the floor - you may need to put down a large sheet of white paper to see it clearly. Measure the shadow and compare with the length of the original.

If using a lamp source, investigate where you get the best shadow image on the screen - how far away from the lamp or screen?
