1 NGfL CYMRU GCaD Breathing and Respiration......the same or different?

2 NGfL CYMRU GCaD Getting started 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

9 NGfL CYMRU GCaD Thinking images! Show your two groups of animals by clicking on the images to change the colour of the frames. Then, explain in the green box below why you chose these two groups. Reset Thinking images!

10 NGfL CYMRU GCaD 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!)

11 NGfL CYMRU GCaD The Big Idea Many people get confused between breathing..... and..... respiration THEY ARE NOT THE SAME THING!

12 NGfL CYMRU GCaD For example: In Artificial Respiration (also known as The Kiss of Life) you can help save someones life by helping them to breathe, but you cant do their respiration for them.

13 NGfL CYMRU GCaD Also in a dusty or dangerous atmosphere you might use a respirator to help you to breathe more easily, but it doesnt do your respiration for you.

14 NGfL CYMRU GCaD So to find out what you understand about this topic already heres a Quick Quiz... There are only 3 questions! Q1In which part(s) of your body does breathing take place? Q2In which part(s) of your body does respiration take place? Q3 Which is a chemical process? Breathing? Respiration? or both?

15 NGfL CYMRU GCaD 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)

16 NGfL CYMRU GCaD 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 hereclick here

17 NGfL CYMRU GCaD Structure of the respiratory system Click here 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 Systemclick here

18 NGfL CYMRU GCaD Now its your go! Your task is to make a working model of your respiratory system Heres 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

19 NGfL CYMRU GCaD 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 (dont let any one else see them yet!) Place them face down on the table 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!) Place them in rank order with the best at the top Write down your groups four best success criteria Now to make your model......

20 NGfL CYMRU GCaD Building your model 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

21 NGfL CYMRU GCaD Your model may look something like this Can you describe and explain what is happening in the two photos?

22 NGfL CYMRU GCaD 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 systemReal life human respiratory system

23 NGfL CYMRU GCaD 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? Reflecting on Success Criteria 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?

24 NGfL CYMRU GCaD How does the respiratory system work? How breathing happens is quite complicated! Its all to do with pressure changes in the chest. Click hereClick here for an animation to see and hear how it happens

25 NGfL CYMRU GCaD Show solution In what order does everything happen? chest volume increases Intercostal muscles contract Pressure inside chest decreases chest moves up and out Air rushes into lungs Diaphragm muscle contracts 1 chest volume increases Intercostal muscles contract Pressure inside chest decreases chest moves up and out Air rushes into lungs Diaphragm muscle contracts 2 chest volume increases Intercostal muscles contract Pressure inside chest decreases chest moves up and out Air rushes into lungs Diaphragm muscle contracts 3 chest volume increases Intercostal muscles contract Pressure inside chest decreases chest moves up and out Air rushes into lungs Diaphragm muscle contracts 4 chest volume increases Intercostal muscles contract Pressure inside chest decreases chest moves up and out Air rushes into lungs Diaphragm muscle contracts 5 chest volume increases Intercostal muscles contract Pressure inside chest decreases chest moves up and out Air rushes into lungs Diaphragm muscle contracts 6 Intercostal muscles relax Air rushes out of lungs Chest volume decreases Diaphragm muscle relaxes Pressure in chest increases Chest moves down and in 1 Intercostal muscles relax Air rushes out of lungs Chest volume decreases Diaphragm muscle relaxes Pressure in chest increases Chest moves down and in 2 Intercostal muscles relax Air rushes out of lungs Chest volume decreases Diaphragm muscle relaxes Pressure in chest increases Chest moves down and in 3 Intercostal muscles relax Air rushes out of lungs Chest volume decreases Diaphragm muscle relaxes Pressure in chest increases Chest moves down and in 4 Intercostal muscles relax Air rushes out of lungs Chest volume decreases Diaphragm muscle relaxes Pressure in chest increases Chest moves down and in 5 Intercostal muscles relax Air rushes out of lungs Chest volume decreases Diaphragm muscle relaxes Pressure in chest increases Chest moves down and in 6 Hide solution Show solution Hide solution Click on each box to until you sort the correct order of events in Breathing in and Breathing out!

26 NGfL CYMRU GCaD In what order does everything happen? Click on each box to until you sort the correct order of events in Breathing in and Breathing out! Diaphragm muscle contracts Intercostal muscles contract Chest moves up and out Chest volume increases Pressure inside chest decreases Air rushes into lungs Diaphragm muscle relaxes Intercostal muscles relax Chest moves down and in Chest volume decreases Pressure in chest increases Air rushes out of lungs

27 NGfL CYMRU GCaD Information about respiration 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 By euthman Some of the millions of cells in the lining of the human gutgut Individual human cellsSome of the millions of cells in a stem of a plant By GreenRon

28 NGfL CYMRU GCaD 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

29 NGfL CYMRU GCaD Which chemicals are formed during respiration? They are the same chemicals formed when wood or other fuels are burned, so thats... Carbon dioxide Water The word equation for the reaction is: oxygen + glucose carbon + water + dioxide In the next few slides you will be able to compare the amount of energy released when different foods are burned. energy

30 NGfL CYMRU GCaD 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? Enquiry

31 NGfL CYMRU GCaD 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 Enquiry

32 NGfL CYMRU GCaD Thinking about the variables in your enquiry... Independent variableDependent variableKeep the same for fair test Enquiry

33 NGfL CYMRU GCaD 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! Enquiry

34 NGfL CYMRU GCaD

35 NGfL CYMRU GCaD 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 dont use up the energy ? ********* Maybe you will get the chance to do the experiment for real!

36 NGfL CYMRU GCaD Heres a quick reminder of the chemical reaction happening in respiration Click on the chemicals and drag them to the correct places + + glucose carbon dioxide energy oxygen water

37 NGfL CYMRU GCaD Heres a quick reminder of the chemical reaction happening in respiration energy oxygen water glucose carbon dioxide

38 NGfL CYMRU GCaD Look at these words and statements carefully. Some are about breathing, some are about respiration and some are about both Happens 24/7 in our bodies Uses up glucoseHappens in oak trees Happens in fish Is a type of burning Produces carbon dioxide Happens in every cell Energy is released Is a chemical process Happens because muscles contract and relax Is a physical process We have lungs to do this (Statements also available as word doc. so cards can be made for learners to arrange on paper version of Venn diagram ) In the next activity you will use a Venn diagram to help sort the statements into the different groups

39 NGfL CYMRU GCaD Check your understanding by dragging the words and statements into the correct parts of the Venn diagram Is a type of burning Happens because muscles contract and relax Happens because muscles contract and relax We have lungs to do this We have lungs to do this Happens 24/7i n our body Happens 24/7i n our body Energy is released Energy is released Is a chemical process Happens in fish Happens in oak trees Produces carbon dioxide Produces carbon dioxide Uses up glucose Is a physical process

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

41 NGfL CYMRU GCaD Thinking more about breathing... In what situations might we need help with our breathing? in sports? in workplaces? 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
