Yesterday we did some science skills to make a hat for Roo the kangaroo. We used lots of materials
We used different materials and tested them with water. We made Roo a waterproof hat.
Mrs Hall made a really bad paper hat, so first we made a prediction. Next, we planned what we were going to do. Then we did an experiment to see if the materials were waterproof.
We had a problem, since Mrs Hall made a rubbish rain hat from paper. Mrs Hall had her friend Roo, who had come all the way from Australia. We did an experiment to find out which material was best. The best material was plastic. Roo did have a good rain hat in the end. We got our material and put it over a pot. Then we got a pipette and squeezed some water. If the material was wet and the water went in the pot, the material was not waterproof.
Mrs Hall did not do a very good hat because it was made out of paper and rain goes through paper. We tried the foil. It was waterproof but it was too noisy so we tried the plastic instead. It worked! The plastic hat was waterproof .
We had to test the materials. Nineteen people thought that the best material was tin foil. Ten people thought that plastic would be the best. In the end we chose plastic, because it was waterproof but the noise level was fine. The tin foil was too noisy.
In science, we were experimenting with materials to see if they were waterproof. We tried foil, paper, cling film and newspaper.
Yesterday in science we tested materials by having a pot and putting the materials on the pot. Then we got a pipette, getting the same amount of water, and putting it on the materials. If the water goes through, it is not waterproof.
We had to make a hat for Roo. Mrs Hall tried but it wasn’t too good.
Yesterday Year 2 found lots of ways to see if some material is waterproof. We did that because Roo was so wet, we had to make him a hat. Now Roo is nice and dry and warm in his new hat made by Year 2. We made it out of plastic.
