science

Part A - choose three tasks

1 - Make a simple switch. Show how it could be used to control a light bulb powered by a
battery.

2 - Show how electrical currents produce magnetic, chemical and heating effects, and explain
what happens.

3 - Show that hot air rises.

4 - Make an artificial rainbow by splitting up a beam of white light.

5 - Make a pin-hole camera and understand the principles of operation.

6 - Keep simple weather records over a month, e.g. rainfall, temperature, cloud cover, wind
direction.

7 - Make a simple compass and show the effects of metallic and magnetic materials upon it.

8 - Make a simple periscope.

9 - Show how to recover dissolved substances from a water solution.

10 - Recognise three different constellations.

11 - Make a model to show how the Earth orbits the Sun

Part B - choose three tasks

1 - Make some yoghurt and find out how living organisms are involved in the process.

2 - Grow cress (or a similar plant) and investigate what happens when light and water are
excluded from it.

3 - Use a net and jar to find out how many different creatures live in the water and mud at the
edge of a pond.

4 - Set up a wormery or ant colony and record the activity over a few weeks.

5 - Grow a bean or pea. When the root and shoot are visible investigate what happens when the
seed is turned upside down and left to continue growing.

6 - Collect seeds from various plants and discover how these are protected and dispersed.

7 - Grow crystals or make crystal shapes from paper

8 - Investigate what happens to their pulse rate before during and after exercise.
