2015 BSAA Plant Science – Photosynthesis (Floating Leaf Discs)

Students in the BSAA Plant Science class conduct an experiment demonstrating how oxygen is produced during photosynthesis causing a leaf disc to float. Initially the air is drawn out of the leaf disc using carbon dioxide water (baking soda) in a vacuum created inside a plastic disposable syringe (no needle).
