We were learning about heat today in science. We talked all about hot and cold weather, hot and cold food, what we do if we feel too hot or cold and also hot and cold water. Then we did an experiment to see what happens if you put hot and cold water into a big tub of water.
1. First we filled the tub with room temperature water.
2. Then we put red food colouring in the hot water and blue food colouring in the cold water.
3. When they were ready, we put the two jars into the big tub. The coloured water started to move out of the jars.
5. After a while, all the red water had moved to the top of the tub and the blue water had moved to the bottom.
From watching this, we learned that hot things (liquid and air) go up and blue things go down!
It was great fun!
