Science in Years 5 and 6 – Photosynthesis

The children have been learning about the important process of photosynthesis, which is the means by which green plants use sunlight to convert carbon dioxide from the air and water from the soil into sugar to feed the plants.  Photosynthesis is necessary for life on Earth, as without it there would be no green plants, and without green plants there would be no animals. Years 5 and 6 began this topic by watching a video to understand this process. Then they carried out a simple experiment using an ‘active’ leaf, which is one just removed from a tree or plant, and a bowl of water to observe the oxygen released during photosynthesis. This gave the impression of the leaves ‘breathing’!
