This week in science we continued our work with materials. We were set another task by Professor Pole! He wanted us to choose the most suitable material he could use for his umbrella. He told us it must be waterproof and not absorbent. 
 
We discussed the idea of a fair test – a test where’s only one variable is changed while all the other variables are kept the same. We established the thing that would change in our experiments would be our materials.
 
We tested fabric (felt), tissue paper, paper towels, cardboard and a plastic bag. We made our predictions first just by feeling the materials that might be the most suitable for an umbrella. 
 
We worked in our table groups and tested all the materials using water. At the end of the experiment we came back together to discuss what we found out. We found out that the best material Professor Pole could use would be the plastic bag because it is waterproof and all the other materials were absorbent… pointless for an umbrella!
