The rain maker experiment

Denise and Zara brought along a shared experiment... Denise brought along her science book,  ice in a chilly bag, a baking tin and oven gloves and  mitts. Mrs Maw provided the oven and the pot in the staffroom.

Their hypothesis was that when water heats up it turns into a gas called... steam. If steam hits something cold ( like a tray filled with ice) it will cool down and turn back into water and rain off the bottom of the tray. This is how condensation works.

They did the experiment and proved their hypothesis.

Thank you girls.

        Can you see the drops on the bottom of the tray?
