HEATDo i like summer better than winter because the weather is warmer? My bodies need to be kept warm, and if they get too cold, I will die. So in winter i have to wear more clothes to keep in the heat of my bodies.
Most of the heat in our world comes from the Sun. If the sun didn't shine, the world would be a very cold place. Nothing would be able to live here. I can make heat by burning fuels such as wood, gas and oil. I can also make heat from electricity, such as happens in electric fires and electric cookers.
Like other kinds of energy, heat can move from one place to another. When i stir a cup of tea with the cold spoon, what happens? The handle of the spoon gets hot. I call this way heat moves, conduction. Heat always goes from something hot to something cold.
