Sprinkler Experiment by Grace

Here we are warming up our brains playing challenging games against people from other rooms. 

Grace brought along a water bottle fitted with a straw for her Sprinkler Experiment.

She had cold water inside the bottle and then sat that bottle inside a jug of boiling water.

Grace hypothesised that as the pressure inside the bottle heats up as the water gets warmer... the water will come out the top of the straw like a sprinkler.

When she first did the experiment nothing happened but Aliyah told us all to have some patience. As we waited the cold water inside the bottle slowly heated up and the water started to drip out of the top of the straw. 

We kept waiting and watching... it didn't actually start to spray out like a sprinkler but the longer we waited the more the drips speed up.

We think the heat acted like a catalyst to speed up the drips. The hotter the water in the jug the faster it would heat the cold water in the bottle.

Thanks Grace. Mrs Maw has been so impressed with the way everyone has self managed this activity.

The only person we are waiting for now is Blake. He will bring his experiment ( or a video of it) with him to TAG in Term 4.
