1. Breathing and Respiration...
...the same or different?

2. 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

10. 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. The Big Idea Many people get confused between
breathing and respiration
THEY 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 to
breathe, 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)

16. Can you remember how all the parts of the respiratory system fit together?

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 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

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 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 group’s four ‘best’ success criteria
Now to make your model......

20. 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. 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 differences
Model human respiratory system
Real life human respiratory system

23. 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?

How would we refine our Success Criteria if we made the model again?

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

25. 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!
Breathing in

27. 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
Some of the millions of cells in the lining of the human gutgut
Individual human cells
Some of the millions of cells in a stem of a plant

28. 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. 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
In the next few slides you will be able to compare the amount of energy released when different foods are burned.
energy

30. Enquiry
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?

31. Enquiry
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

32. Enquiry Thinking about the variables in your enquiry...
Independent variable
Dependent variable
Keep the same for fair test

33. Think about how you will record your results
Enquiry
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!

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.

36. Here’s a quick reminder of the chemical reaction happening in respiration Click on the chemicals and drag them to the correct places
carbon dioxide

water
oxygen

37. Here’s a quick reminder of the chemical reaction happening in respiration

38. 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 glucose
Happens 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
In the next activity you will use a Venn diagram to help sort the statements into the different groups
(Statements also available as word doc. so cards can be made for learners to arrange on paper version of Venn diagram )

39. Check your understanding by dragging the words and statements into the correct parts of the Venn diagram

40. Reflection triangle
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?
How will they help you investigate and learn in new situations?
What strategies did you use?
How did they help you with your learning?
Why?
Explain why this was (or was not!) a good idea
Did you work on your own or in a group?

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