Activities - Pitfall traps
Observe the structural adaptations of the plant. Draw and label a scientific diagram of its pitfall trap. Label its features and outline the function of each.
Construct a 3D model of the plant, replicating the plant’s structural adaptations such as colours and surfaces. Use a model of an invertebrate to demonstrate the plant’s trapping mechanisms.
3. Make a pitfall trap
Pitfall traps are used by scientists to catch and study crawling ground-dwelling invertebrates. Use the structural features of the pitcher plant’s trap to construct a pitfall trap to collect invertebrates. Insert it into a garden bed at ground level and leave it overnight. Next day, extract the trapped invertebrates. Use magnifiers to examine their features and infer their structural adaptations.
