10 How did you get on? One way of grouping them would be into: animals which breathe with lungselephant, frog, red kiteandanimals which do not breathe with lungsearthworm, wasp and clown fish(The sea anenome in the photo is an animal which does not use lungs for breathing either!)
11 The Big Idea Many people get confused between breathing and respirationTHEY ARE NOT THE SAME THING!
12 For example:In ‘Artificial Respiration’ (also known as ‘The Kiss of Life’)you can help save someone’s life by helping them tobreathe, but you can’t do their respiration for them.
13 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.
14 So to find out what you understand about this topic already here’s a Quick Quiz ... There are only 3 questions!Q1 In which part(s) of your body does breathing take place?Q2 In which part(s) of your body does respiration take place?Q3 Which is a chemical process? Breathing? Respiration? or both?
15 Quick Quiz answers:Q1 Breathing happens in your lungs, and your muscles in your chest help with this. Your lungs are part of the respiratory system.Q2 Respiration happens in every cell in your body (and in fact every living cell in plants and animals!)Q3 Respiration is a chemical process.(Breathing is a physical process)

17 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!The second link on this slide will only work in schools in Wales or those schools that have a current subscription with Echalk.Now click here to this drag and drop activity on the Respiratory System
18 Here’s a list of what you will need to do in your group... Now it’s your go! Your task is to make a working model of your respiratory systemHere’s a list of what you will need to do in your group...Set your success criteria (activity on next screen)Build your working modelDraw and demonstrate your model explaining how it worksDiscuss and record similarities and differences between the model and the real thingReflect on your success criteria
19 Setting your success criteria What would a good model of the respiratory system be like?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!)Place them face down on the tableAs a group turn over all the cards to read the different success criteria and discuss them in your group (some may be the same!)Place them in rank order with the ‘best’ at the topWrite down your group’s four ‘best’ success criteriaNow to make your model......
20 Building your modelYou can use: a balloon, a filter funnel and a plastic bottleCan 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
21 Your model may look something like this Can you describe and explain what is happening in the two photos?
22 How is your model similar to and different from the real human respiratory system? Fill in the chart to show similarities and differencesModel human respiratory systemReal life human respiratory system
23 Reflecting on Success Criteria Use this chart to think about your Success Criteria for the model making activityOur 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?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?

27 Information about respiration This is a chemical processIt happens all the time in every cell in all animals and plantsIt happens so cells can get the energy they needThe most active cells do the most respirationSome of the millions of cells in the lining of the human gutgutIndividual human cellsSome of the millions of cells in a stem of a plantBy euthmanBy GreenRonBy euthman
28 What chemicals does respiration need? Basically ... a type of fuel and a gas to “burn” it withCarbohydrate (actually glucose, a type of sugar) is the fuel our body usesOxygen is the gas used to “burn” itThey react together inside cells to release the energy they need
29 Which chemicals are formed during respiration? They are the same chemicals formed when wood or other fuels are burned, so that’s...Carbon dioxideWaterThe word equation for the reaction is:oxygen + glucose carbon + water +dioxideIn the next few slides you will be able to compare the amount of energy released when different foods are burned.energy
30 EnquiryIn 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?
31 EnquiryIn 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 foodmass of foodvolume of water in the tube
32 Enquiry Thinking about the variables in your enquiry... Independent variableDependent variableKeep the same for fair test
33 Think about how you will record your results EnquiryThink about how you will record your resultsRemember 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!
35 Follow up from the Burning Food experiment 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!This slide goes immediately after the Burning Food animation. Slide 35 in my version.
