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

Getting started
NGfL CYMRU GCaD
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

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
NGfL CYMRU GCaD
Many people get confused between
breathing ..... and ..... respiration
THEY ARE NOT THE SAME THING!
www.ngfl-cymru.org.uk
For example:
NGfL CYMRU GCaD
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
NGfL CYMRU GCaD
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
NGfL CYMRU GCaD
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?
Type your answer here.
Q2
In which part(s) of your body does respiration take
place?
Type your answer here.
Q3 Which is a chemical process? Breathing?
Respiration? or both?
Type your answer here.
www.ngfl-cymru.org.uk
Quick Quiz answers:
NGfL CYMRU GCaD
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)

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

the parts of the respiratory system in the

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
NGfL CYMRU GCaD
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
NGfL CYMRU GCaD
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......
www.ngfl-cymru.org.uk
Building your model
NGfL CYMRU GCaD
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
NGfL CYMRU GCaD
Your model may look something like this
Can you describe and explain what is happening in
the two photos?
www.ngfl-cymru.org.uk
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 system Real life human respiratory
system

Reflecting on Success Criteria
NGfL CYMRU GCaD
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 does the respiratory system work?
How breathing happens is quite
complicated!
It’s all to do with pressure changes in the
chest.

Information about respiration
NGfL CYMRU GCaD
• 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

lining of the human gutgut

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
www.ngfl-cymru.org.uk
NGfL CYMRU GCaD
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
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?
www.ngfl-cymru.org.uk
Enquiry
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

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!

Follow up from the Burning Food experiment NGfL CYMRU GCaD
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!

you use?
Did you
work on

Why?

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)

us to breathe in these situations
in
workplaces?
