The Year 8’s had an exciting Science lesson today experimenting on plants for their current topic: photosynthesis. Their task was to check if the plants contained starch, a substance produced during the process. They did this by boiling the plants in alcohol, breaking down the chlorophyll and covering them with iodine. Iodine is an indicator that turned the plants black in the presence of starch! It was exciting to watch the plants change in colour!
