Water before freezing
You need: A freezer-safe unbreakable container, water, paper and pencilWith you beside them, your child watches you tip a little water inside the container: it flows. Draw it together. Put the container in the freezer yourself, leaving room for expansion. Without a freezer, draw water and the ice it could become.

Look at the frozen water
You need: The container on a tray, paper and pencilWhen frozen, an adult brings out the container and gently tips it to show that the solid ice keeps its shape. Observe without touching or tasting. Draw what changed. Leave it safely on a tray at room temperature to watch it melt; wipe spills.

Could we change it back?
You need: The drawings and a pencilCompare the melted water with your first drawing. Order pictures of water, ice and water again. Explain that an adult could freeze this water again. Retell the sequence using freeze and melt. Empty the container afterwards; the activity water is not for drinking.
