This resource from Science & Plants for Schools (SAPS) describes the work of Charles Darwin on carnivorous plants to determine what causes the leaves to curl up when stimulated.
Darwin’s experiments are very easy to repeat. These teachers' notes describe several investigations which students could carry out, such as varying the foodstuff or chemical to be used, the size of the stimulating food material or the concentration of a chemical.
The presentation that accompanies the teaching ideas shows a range of carnivorous plants and their habitats.
Curriculum links include: evolution, plant responses, habitats, natural selection, adaptation.
