Year 8 Nutrition Assessment

Nutrition

You should know:

a) about the need for a balanced diet containing carbohydrates, proteins, fats, minerals, vitamins, fibre and water, and about foods that are sources of these

b) the principles of digestion, including the role of enzymes in breaking down large molecules into smaller ones

c) that the products of digestion are absorbed into the bloodstream and transported throughout the body, and that waste material is egested

d) that food is used as a fuel during respiration to maintain the body's activity and as a raw material for growth and repair

To demonstrate b, c and d you need to produce a poster or leaflet etc.

You must

· Include a labelled diagram showing the major organs of the digestive system (level 4) (include the organs which the food doesn’t actually travel through, like the pancreas)

· Describe the route of food through the digestive system (level 4/5)

· describe the basic function of each of the organs above (can be on the diagram)(level 5)

You should

· explain what enzymes do in detail, including at least the names of the main enzymes, the type of food molecule they act on and the type of molecule produced (could be a table) (level 7)

· describe what happens to the molecules produced and the material left behind (level 5/6)

· describe what the molecules produced by the enzymes are used for in the body, using correct scientific terms (could be a table) (level 6)

You could

· explain how some organs are adapted to their function – e.g. how is absorption made efficient in the intestine or how does the stomach cope with the acid it contains (level 8)
