A Year 11 module from the Salters’ Key Stage Four double award science course. The context for this module is the use of scientific ideas to explain human performance. Students discuss what is meant by being ‘fit’. They compare different uses of the word 'work' and are given a formal definition. Calculations of work done and rate of working lead to measurements of their own power and fitness.

Respiration is introduced as a mechanism for transferring energy in tissues. Aerobic and anaerobic respiration are compared. The function of the lungs and the circulatory system in transporting materials around the body is studied.

Ideas about levers are revised. Tests with a model arm show the function of bones and muscle pairs in producing movement. Work on turning moments leads to ideas about balance and centre of mass. These ideas are applied to a comparison of different high jump techniques.
Ideas about potential and kinetic energy are reviewed. Students measure the energy transferred in a variety of simple tasks. Pole vaulting and free fall parachuting are used as contexts for analysis of energy conversions, leading to the concept of conservation of energy.

Section 3: A living machine!
Ideas about levers are revised. Tests with a model arm show the function of bones and muscle pairs in producing movement. Work on turning moments leads to ideas about balance and centre of mass. These ideas are applied to a comparison of different high jump techniques.

Section 4: Faster and higher
Ideas about potential and kinetic energy are reviewed. Students measure the energy transferred in a variety of simple tasks. Pole vaulting and free fall parachuting are used a contexts for analysis of energy conversions, leading to the concept of conservation of energy.

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
