Fair Test

We used the experiments we have done so far this term to make predictions about what would be the best material to use as an umbrella for our class teddy, Freddie. We made sure that all the parts of the experiment were fair. This meant we kept everything the same: the amount of water, the height from which we dripped the water, the container and the time we waited to see the result. We only changed the material to be tested each time. We wrote up our experiments in our books.
