Investigating nappies experiment

This afternoon Year 5 Kestrels investigated nappies!

They looked at what happened when liquid was added to the grains in a nappy.

Some of the predictions…

The children then cut open a nappy, took out the tiny grains and collected them in a bowl. Once the grains were sieved to remove any cotton wool the children noted how much they had left.

They then added water to the grains, 10ml at a time, and recorded their findings.

They could see that each time they added water the grains got bigger and bigger, but remained dry.

Finally, they added salt and observed the grains. The grains became wet!
