The Year 11 students are working towards their GCSE Entry Level Science. Our recent work has focussed on photosynthesis.
The pupils were asked to set up an experiment to see the ideal conditions for photosynthesis to take place. Our plan needed to show each stage of the experiment and how we would record the results.
Our method involved placing some pond weed into a funnel. Water was added into a test tube, leaving a small gap at the top for oxygen.
A light bulb was placed next to the apparatus. We counted the number of oxygen bubbles that were created. This process was then repeated with the bulb 30cm away.
The Year 11 students were able to conclude that more oxygen is created with the light source closer. The results were recorded in a graph.
