Investigating Gravitropism Using Seedlings
One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. An intriguing way to demonstrate gravitropism in action over the course of a lesson. Using black film canisters, a freshly cut seedling stalk (hypocotyl) is attached to the lid, the lid replaced, and the resulting direction of growth of the seedling assessed after approximately one hour. The stalk will grow towards the vertical, demonstrating gravitropism.
The resource is suitable for use at Key Stage Three and GCSE.
