NGf L CYMRU GCa D Breathing and Respiration

NGf. L CYMRU GCa. D Breathing and Respiration. . . the same or different? www. ngfl-cymru. org. uk

Getting started NGf. L CYMRU GCa. D Look at the animals in the next 6 slides Think of ways in which you could put them into two groups with 3 animals in each group www. ngfl-cymru. org. uk

Choose your Groups! NGf. L CYMRU GCa. D Show your two groups of animals by clicking on the images to change the colour of the frames. Then, explain in the text box below why you chose these two groups. 1 2 3 4 5 6 Reset Thinking images! www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D How did you get on? One way of grouping them would be into: animals which breathe with lungs elephant, frog, red kite and animals which do not breathe with lungs earthworm, wasp and clown fish (The sea anenome in the photo is an animal which does not use lungs for breathing either!) www. ngfl-cymru. org. uk

The Big Idea NGf. L CYMRU GCa. D Many people get confused between breathing. . . and. . . respiration THEY ARE NOT THE SAME THING! www. ngfl-cymru. org. uk

For example: NGf. L CYMRU GCa. D In ‘Artificial Respiration’ (also known as ‘The Kiss of Life’) you can help save someone’s life by helping them to breathe, but you can’t do their respiration for them. www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D Also in a dusty or dangerous atmosphere you might use a respirator to help you to breathe more easily, but it doesn’t do your respiration for you. www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D So to find out what you understand about this topic already here’s a Quick Quiz. . . There are only 3 questions! Q 1 In which part(s) of your body does breathing take place? Q 2 In which part(s) of your body does respiration take place? Q 3 Which is a chemical process? Breathing? Respiration? or both? www. ngfl-cymru. org. uk

Quick Quiz answers: NGf. L CYMRU GCa. D Q 1 Breathing happens in your lungs, and your muscles in your chest help with this. Your lungs are part of the respiratory system. Q 2 Respiration happens in every cell in your body (and in fact every living cell in plants and animals!) Q 3 Respiration is a chemical process. (Breathing is a physical process) www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D Can you remember how all the parts of the respiratory system fit together? To play a game where you try to connect all the parts of the respiratory system in the correct order. . . click here www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D Structure of the respiratory system Click here for a tutorial about the structure of the respiratory system. Watch and listen carefully as it ends with a quick quiz! Now click here to this drag and drop activity on the Respiratory System www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D Now it’s your go! Your task is to make a working model of your respiratory system Here’s a list of what you will need to do in your group. . . • Set your success criteria (activity on next screen) • Build your working model • Draw and demonstrate your model explaining how it works • Discuss and record similarities and differences between the model and the real thing • Reflect on your success criteria www. ngfl-cymru. org. uk

Setting your success criteria NGf. L CYMRU GCa. D What would a good model of the respiratory system be like? Ø Each person in your group thinks of two success criteria and writes them down on separate sheets/cards (don’t let any one else see them yet!) Ø Place them face down on the table Ø As a group turn over all the cards to read the different success criteria and discuss them in your group (some may be the same!) Ø Place them in rank order with the ‘best’ at the top Ø Write down your group’s four ‘best’ success criteria Now to make your model. . . www. ngfl-cymru. org. uk

Building your model NGf. L CYMRU GCa. D You can use: a balloon, a filter funnel and a plastic bottle • Can you get your model respiratory system to breathe? • Draw your model and label it to show which parts represent the different parts of the respiratory system www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D Your model may look something like this Can you describe and explain what is happening in the two photos? www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D How is your model similar to and different from the real human respiratory system? Fill in the chart to show similarities and differences Model human respiratory system Real life human respiratory system www. ngfl-cymru. org. uk

Reflecting on Success Criteria NGf. L CYMRU GCa. D Use this chart to think about your Success Criteria for the model making activity Our Success Criteria were. . . How far did we meet the Success Criteria? Why do we think that? How would we refine our Success Criteria if we made the model again? www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D How does the respiratory system work? How breathing happens is quite complicated! It’s all to do with pressure changes in the chest. Click here for an animation to see and hear how it happens www. ngfl-cymru. org. uk

Information about respiration NGf. L CYMRU GCa. D • This is a chemical process • It happens all the time in every cell in all animals and plants • It happens so cells can get the energy they need • The most active cells do the most respiration Individual human cells By euthman Some of the millions of cells in the lining of the human gutgut By euthman Some of the millions of cells in a stem of a plant By Green. Ron www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D What chemicals does respiration need? Basically. . . a type of fuel and a gas to “burn” it with • Carbohydrate (actually glucose, a type of sugar) is the fuel our body uses • Oxygen is the gas used to “burn” it • They react together inside cells to release the energy they need www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D Which chemicals are formed during respiration? They are the same chemicals formed when wood or other fuels are burned, so that’s. . . • Carbon dioxide • Water The word equation for the reaction is: oxygen + glucose carbon + water + dioxide energy In the next few slides you will be able to compare the amount of energy released when different foods are burned. www. ngfl-cymru. org. uk

Enquiry NGf. L CYMRU GCa. D In this enquiry you will be burning some snack foods to compare how much energy they release. What could we measure to get an idea of how much energy is in the food? www. ngfl-cymru. org. uk

Enquiry NGf. L CYMRU GCa. D In this enquiry you will be able to collect the heat energy from the burning food in a tube of water, and then work out the temperature rise of the water. The equipment will be set up like this. You will be able to change the: • type of food • mass of food • volume of water in the tube www. ngfl-cymru. org. uk

Enquiry NGf. L CYMRU GCa. D Thinking about the variables in your enquiry. . . Independent variable Dependent variable Keep the same for fair test www. ngfl-cymru. org. uk

Enquiry NGf. L CYMRU GCa. D Think about how you will record your results Remember you are investigating which snack food contains most energy. There will be three foods to investigate: Biscuits, Frazzles and Hula Hoops. You will need to design a chart to record your results! Make sure you carry out fair tests! www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D Click on the image of the experiment to run the animation on line. If you have downloaded and extracted the zip file containing the animation then place this Power. Point and the extracted folder (breathing-eng) side by side in a new folder and click on this image. www. ngfl-cymru. org. uk

Follow up from the Burning Food experiment NGf. L CYMRU GCa. D The Burning Food experiment gives an idea of what is happening in our cells during respiration. • What have you learned from your results? • Draw one or more graphs to show your results. ***** • How do our bodies use the energy from respiration? • What could happen if we eat too much snack food and don’t use up the energy ? ***** Maybe you will get the chance to do the experiment for real! www. ngfl-cymru. org. uk

Reflection triangle NGf. L CYMRU GCa. D Reflection Triangle to help you think about your work - Start at the base of the triangle and add in your ideas When might you use these strategies again? What strategies did you use? Did you work on your own or in a group? How will they help you investigate and learn in new situations? How did they help you with your learning? Why? Explain why this was (or was not!) a good idea www. ngfl-cymru. org. uk

NGf. L CYMRU GCa. D Thinking more about breathing. . . In what situations might we need help with our breathing? in sports? in hospitals? Choose one of these situations (or think of another of your own) Research and explain how science has helped us to breathe in these situations in workplaces? www. ngfl-cymru. org. uk
