- Ask pupils about 'high energy' drinks, who uses them and what they contain, and provide pupils with secondary sources of information. Establish that glucose is a major constituent of such drinks/foods and ask pupils to relate this to what they learnt about digestion of carbohydrates (starches) in unit 8A 'Food and digestion'. Use secondary sources,
eg video clips, software simulations, to show how small molecules,
eg glucose, are transported in the blood to other parts of the body,
eg muscles, brain.
