Discovery Science – Step 1 – Snake Spiral

To complete this activity, the children cut out the spiral and decorated it to look like a snake. The children then cut along the spiral and attached a piece of thread to the snake’s head. They hung the snakes over a hot radiator. The snake spun as the warm air rose.

The children learned that warm air is lighter than cold air. Warm air rises and cold air comes in to take its place. This causes air currents – both indoor and outdoor. These are called convection currents.
