This demo from Science and Plants for Schools demonstrates a quick and easy plant practical for your biology lab.
Charles Darwin called the Venus' Fly Trap 'one of the most wonderful plants in the world'. In this activity, students investigate what causes a Venus' Fly Trap to shut its trap. These experiments are related to a series of investigations that Darwin carried out as part of his work on evolution and adaptation.
This can easily be built up into a broader investigation, or used as a quick practical to introduce the topics of plant defences, adaptations and osmosis.
