The Keas have been learning to write explanations. We have also been learning about the water cycle. This week we did an experiment to find out about evaporation. We placed a wet hand print onto a paper towel then drew around it with a felt pen then hung it on a line in the classroom. After this we made some predictions about what would happen to our handprint.
Logan – The hand print might get bigger and take over the whole page.
Mya – The hand print might change colour and get smaller.
Eli – The hand print will get hard.
Alexander – Water might dry out and the print will stay there.
Jacob – It will stay soggy. If it’s a windy day the water will drop on the floor.
Blake – Water will come out of the hand print. Water will go on the floor even though it is not dripping.
Seth – It would dry up.
Jak – It would stay soggy.
Emma – The colour would change shape after using the pen.
Alex F – It would dry up.
Brandon – It would spread out more.
We then wrote some explanations about our experiment and what we found out.
Here are three for you to read.
We had a paper towel. We had to put our hand in the bucket and we put out hand on to the paper towel. We had to write out name on the paper towel. I drew around my hand and the paper towel dried. Heat made my hand dry. The hands are dried now. The water has evaporated. By Emma
On Tuesday morning I made a hand print on a paper towel. Next I put my name on the paper towel. Thirdly, I put my hand into a cold bucket of water which felt as cold as an ice cube. Then I put my sub-zero hand on the paper towel. It looked like bulls horns. Finally the water evaporated into the warm invisible air. It became a gas. By Jacob
