Support and movement
Our musculoskeletal system supports and protects our body as well as making it possible for us to move about. Plants have a kind of skeletal system, too – a framework of tough fibres that support the whole plant and also form part of the plant’s transport network.
Observing earthworm locomotion
Collect earthworms and observe how they move on different surfaces. Listen to the worms moving on paper.
Structure of synovial joint with tendons and ligaments
Dissect a pig’s trotter to explore the structures around a synovial joint.
Extracting fibres from plants
Extract fibres from plant material. Assess their strength and stiffness. Consider commercial usefulness of fibres from plants.
