Y8 Diet, Health and Fitness Learning Objectives All Pupils should be able to: 1. know the three main food types: proteins, fats and carbohydrates 2. know that different foods supply different types of food and what the best sources for each type of food are 3. know the main function of carbohydrates in the diet is to supply energy 4. know the main constituents of carbohydrates and what deficiency diseases are caused when they are lacking in the diet 5. know the main function of proteins is they are the material used to build cells during growth and tissue repair 6. identify the main constituents of proteins and the deficiency diseases caused when they are lacking in the diet 7. understand that proteins are made from amino acids joined together in long chains and that amino acids must be supplied ready-made in the diet 8. recall the main function of fats in the diet is to supply and store energy in the body 9. recall the main constituents of fats: fatty acids and glycerol, and what the diseases are when too much fat is consumed in the diet or fat is deficient in the diet 10. know the functions of the different minerals and vitamins in the diet 11. know how to calculate how much energy a food supplies 12. know how the calorimeter works and why it is an improvement on just burning a peanut from a bunsen 13. identify that different people need different amounts of energy from their diet and the reasons why 14. produce a histogram of the constituents of their diet for a 24 hour period 15. recall that tissues are specialised for function 16. name the main bones of the skeleton 17. describe skeletal function 18. name the main parts of the synovial joint 19. name 4 types of joint – ball and socket, hinge, gliding and swivel 20. know that muscles contract and pull but don’t push 21. know that muscles work in antagonistic pairs – example biceps and triceps 22. know that muscles attach to bones by inelastic tendons 23. know that Ligaments join bones reducing the chance of dislocation 24. know that energy from respiration is needed for muscle contraction 25. know that muscles also come in smooth types e.g. in the gut and cardiac in the heart 26. know the structure and main names of heart areas 27. know the main role of red blood cells, white blood cells, plasma and platelets.
