Investigating Factors Affecting Photosynthesis Using Leaf Discs

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. An enjoyable and reliable practical activity allowing students to compare factors affecting photosynthesis. Possible investigations could include the rate of photosynthesis in sun and shade plants, and at different light intensities. Students punch out small discs from leaves, and float them in a syringe of sodium hydrogen carbonate solution. Once gas is evolved by photosynthesis, the leaf discs rise and fall.

The resource is suitable for use at Key Stage Three, GCSE and A level.
