Explain day, month and year in terms of the relative motion of the Sun, the Earth and the Moon |
| 1 | Establish the difference between the 24 hour rotation and 365 (approx.) days orbit of the Earth. The Earth spins once every 24 hours from west to east. As the Earth spins the sun shines on one side only at a time - daylight on that side. Earth orbits the Sun in an elliptical (oval) path - one year. |
| 2 | Through practical activity show how the tilt of the Earth causes seasonal changes (a datalogger could be used to collect data about temperature and light using a tilted globe). |
| 3 | The Moon (our nearest neighbour) travels round the Earth taking about 28 days to do so. Record changes in the shape of the Moon over a calendar month and illustrate as a diagram. |
