  1. LO: explain that plants and animals respire Compare and contract combustion and respiration Respiratory System Ventilation ( breathing) Recap questions, discuss with your partner How you know something is alive? Why do we breathe? Make a list of things we need energy for? 4. Can you write the word equation for combustion Fuel + ______ 5. Can you write the word equation for respiration Glucose + __________

  2. Asian fish market Which of these organisms respire? A B C ALL OF THEM! E F D

  3. Releasing energy from food • This is called RESPIRATION Glucose + oxygen  carbon dioxide + water + ENERGY This reaction occurs in all living organisms

  4. combustion Carbon Dioxide FUEL + OXYGEN + Water + DEMO: screaming jelly baby ENERGY How is combustion similar to respiration and how is it different?

  5. Breathe in, breath out • So how is breathing different to respiration. Glucose + oxygen  carbon dioxide + water + ENERGY

  6. Ribs- protect the chest Windpipe- carries air to the chest Bronchioles- contain alveoli Diaphragm- muscular sheet Ventilation (breathing) occurs in the lungs it allows useful gases to diffuse into blood and waste gases to be removed Windpipe- carries air to the chest Rib muscles – to raise and lower the ribs Left Lung Right lung Left bronchus Bronchioles- contain air sacs called alveoli Ribs Heart Ribs –protect the chest Diaphragm- muscular sheet

  7. Are breathing and respiration the same thing??? Breathing is the movementof air in and out of the lungs. You can see people breathing and it’s one of the first things a doctor looks for to see if someone is alive. Respiration is a chemical reaction going on inside all living cells. It releases energy from glucose to keep the body alive.

  8. Demonstrating respiration and breathing. Red blood cells Lungs Oxygen diffuses into red blood cells Right hand side of heart Left hand side of heart Pushes along Pushes along Gives out carbon dioxide Takes in oxygen Cells

  9. “Double Loop” System BREATHING Head When the lungs takes in oxygen that is needed for respiration and takes out carbon dioxide gas Lungs RESPIRATION Oxygen is taken in by the cells of the body and the head and is combined with glucose to transfer energy to something useful for the body e.g. movement Right side - Heart - Left side Cells of the body

  10. Role play questions • What does the blood carry from the lungs to the cells? • What does the blood carry from the cells to the lungs? • Where does breathing occur in this roleplay? • Where does respiration occur?

  11. Fish Head Video Explain with reasons whether the fish is dead or alive Are the gills moving? If the fish is not breathing, why is it still moving? When would you determine when a person/animal is dead?

  12. Breathing Respiration Not sure AMBER GREEN RED • This occurs in both plants and animals? • The lungs are the organs used for this?

  13. Breathing Respiration Not sure AMBER GREEN RED • When you exercise this will be increased? • The amount of glucose available in the body controls the rate of which process?

  14. Breathing Respiration Not sure AMBER GREEN RED • This process brings oxygen into the body? • This is the process where oxygen is used to produce energy?

  15. Breathing Respiration Not sure AMBER GREEN RED • The amount of glucose available in the body controls the rate of which process? • Which of these two processes is a form of excretion for the body?

  16. Breathing Respiration Not sure AMBER GREEN RED • This is the process where oxygen is used to produce energy? • During which process is carbon dioxide produced?

  17. 8B Respiration – the truth, and quite few lies True or false? 1.Respiration means breathing. 2.Respiration occurs in all body cells. 3.Respiration gives out oxygen. 4.Carbon dioxide is used up by respiration. 5.Respiration is a chemical process that releases energy. 6. Plants do not respire. FALSE TRUE FALSE FALSE TRUE FALSE

  18. 8B Respiration – the truth, and quite few lies True or false? 1.Respiration releases energy from glucose. 2.Oxygen is needed for respiration in humans. 3.We die without oxygen because we cannot respire. 4.Respiration is a bit like burning. 5.People do not respire while they are asleep. 6. The more energy we need, the less we respire. TRUE TRUE TRUE TRUE FALSE FALSE

  19. 8B Respiration and combustion Respiration and combustion - same thing? Or not? Are these statements... …only true about respiration? (R) …only true about combustion? (C) …true about respiration and combustion (R & C) Needs a high temperature (C) Gives out light (C) Happens at room temperature (R) Gives out heat (R & C) Needs enzymes to work properly (R) Uses oxygen (R & C) Gives out carbon dioxide (R & C)
