Animal movement
A closer look at suitable test animals can reveal fascinating patterns in their behaviour. Simple behaviour such as movement can help us understand what influences or controls animal behaviour. Experiments

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 in plants
Follow the movement of coloured water through plants – from root to stem to leaves – and establish the path of movement in preparation for investigating the tissues involved. Experiments

Diffusion
of molecules in vapour and in solution. It is a core concept in science – including the physics of random molecular movements, the chemistry that results from random collisions, and the movement of essential molecules in biological systems, including...

Transpiration in plants
Accurate quantification of the movement of water into plants is possible with a potometer. Assessing the impact of changing humidity and air movement on plant uptake of water provides essential experience for understanding plant adaptations. Some...

Animal reactions
This topic includes examples of behaviours in response to different stimuli. They may involve some movement, but not movement of the whole body from place to place. Experiments
