Keeping Simon dry in Class 4.

Date: 2nd Jul 2021 @ 10:54pm

Class 4 have been investigating materials in science this week. We wanted to find a material that is waterproof and could be used to make a rain coat for our class teddy Simon.

We experimented with wool, cotton and a plastic sheet. Before we tested the materials we made a prediction, where we tried to guess which material would actually be waterproof.  We made sure that our test was fair by using the same amount of water for the same amount of time with each material.

We had a great time putting the materials on Simon and testing them out.

By the end of the experiment, we found out that if Simon’s coat was made of cotton or wool, he would get very wet. The material that was best at keeping Simon dry was the plastic sheet. So this material would be good to make a raincoat.
