Level 3 · Science S3.9

Light, colour and sound

Light bounces, bends and splits into colours, and sound is a wave that needs something to travel through.

Draw rays bouncing off a mirror, see why a coin appears in a cup of water, find how the eye and glasses make an image, split light into colours, predict the colour of things in coloured light, and follow sound as a wave: how fast it goes, what makes it high or loud, and how to protect your hearing.

For parents and teachers

For learners who can read a page alone and do sums with the four operations. In many schools this fits children of about 11 to 13, and older learners can use it too. Activities use a small mirror, a cup and water, a jar, a dish, paper, a pencil and a ruler, string, and a row of people. Nothing needs the Sun except one sunlight activity by a window, and nobody ever looks at the Sun or points a mirror at a face. A learner can work alone: every exercise has its answer and the reason for it.
