6. 5D Changing State Melting Evaporation Solid Liquid Gas  Freezing Condensing Evaporation When a liquid warms up and starts to turn into a gas. Condensation When water vapour cools and turns to liquid. Melting When a solid warms up and turns into a liquid. The water cycle in nature, is an excellent example of the processes of evaporation and condensation. Freezing When a liquid gets cold enough to turn into a solid. Water turns into snow or ice when it gets verycold. When it warmsup it turns back to water Lava is molten rock, but it has to be very hot to melt rock! Chocolate goes soft and gooey if you heat it.

9. 5E Earth Sun and Moon The earth spins or rotates on its own axis. It takes 24 hours for the Earth to spin once on its axis. As the Earth spins, some parts are facing towards the sun and some parts face away from the sun. This causes day and night. The earth spins from west to east. This means the sun always rises in the east and sets in the west. The sun moves across the sky in an arc and is at its highest point at midday. During the winter, the sun is much lower in the sky and the number of daylight hours is much less. DAY & NIGHT Year 5 Revision booklet
