Snake Spiral #scienceweek

Today’s Science lesson was an investigation into how air moves when heated and cooled.

We started the lesson by making snake spirals. We drew a spiral and decorated it with snake patterns.

We cut out the snakes and attached string.

We discovered that when we held our snakes over the radiator, the snakes began to rotate.

This was due to the hot air rising from the radiator. We did some research and learned that hot air is lighter than cold air. So hot air rises and cold air comes in to take its place. This causes air currents called convection currents.

The air above the radiator is warm air which rises to make the snake swirl.

Now we know why Mr Charlton’s and Miss Moore’s rooms upstairs are always warmer than ours!
