MATERIALS: • 100m heavy string • 9 pieces of heavy cardboard • scissors • permanent marker INSTRUCTIONS: 1. Learners are divided up into 8 groups and each group is assigned a planet. 2. Each group must cut apiece of string to represent the distance of their planet from the sun, using the lengths indicated in the table below. The actual distance of the planets from the Sun is given in kilometers (km) and the length of the string is in meters (m). 1 kilometer is 1000 meters. Planet Actual distance from Sun (km) Mercury 58 0.4 Venus 108 0.7 Earth 150 1.0 Mars 228 1.5 Jupiter 779 5.2 Saturn 1 434 9.6 Uranus 2 873 19.2 Neptune 4 495 30.0 Length of string (m) 3. Each group must cut acircle out of the cardboard and write the name of their planet and the actual distance from the Sun on it. 80 Earth and Beyond
4. Make a hole at one edge of the cardboard and tie the length of string to it. 5. Now it is time to go outside to a big open space, like the school field! 6. Your teacher will be the Sun in the centre. She does not move as the Sun does not move. 7. One member from each group must hand the "Sun" the end of their length of string and then stretch out their length of string. 8. Do this one at a time starting from Mercury and going out to Neptune. You do not all need to be in a straight line but can directions. 10. Walk around so that you can all see the scale model of the solar system. Teacher's Note Explain to learners that on this scale, the nearest star (other than the Sun), would still be 2 748 km away! 11. Now comes the tricky part – making the planets orbit the Sun. 12. Select one learner from each group to be the planet. 13. He/she must pick up the planet and walk in a circle around your teacher, all going in the same direction. Try and walk at the same speed. Teacher's Note Hold all the ends of the strings in one hand above your head so that you are like a maypole and the learners will revolve around you. 14. Swop with other learners in your group so that you each have a turn to be a planet orbiting the Sun. Chapter 1. Planet Earth 81
