Today the whole school carried out science experiments. In Elm Class we investigated how leaves create oxygen. This links nicely to our topic and allows us to appreciate how important rainforests are for human life.
We decided to pick two identical leaves and place them in identical amounts of water. One glass with the leaf was placed in a sunny spot and the other in a darkened room. We left them for an hour and then observed what had happened. We found that the leaf left in the sunshine released lots of bubbles of oxygen whereas the leaf in the dark released very few. Most of us predicted this would happen.
We have all written up our scientific investigations and thought about the variables we used and how we made the experiment a fair test.
