Organs
• Can you name some organs found in our
body?
• You have 2 minutes in your groups to
write the names on your whiteboards.
What is an Organ?
• An organ is something which does a
particular job in the body.
• An organ is made up from different types
of tissues.
How is the body organised?
Groups of organs form
organ systems.
For example, the human digestive
system is made up of several organs
including the mouth, gullet, stomach
and small intestine.
The different organs in a system are
linked together by tubes or vessels.
What other human body systems can
you think of?
Do plants
have organs
too?
Do plants
have organs
too?
YES!! You’re right!!!
Organs
• Get yourselves into pairs and organise
yourselves so one person is the body the
other the artist decide now 1 min
• If you’re the body you must wear the
bin bag if you’re the artist get your
whiteboard pen ready
• You will be given different organs to
draw on your body decide the position
and write the name and draw what you
think it looks like!!
• Get ready!!!
Organs

Stomach
Skin
Lungs
Kidneys
Brain
Liver
• What organ systems do you know??
Remember a
system is two or
more organs
working together!
Building a body
• Using your body parts can you construct
a full working body
Start at the back
with the spine
and work your
way forwards
• Hint; look at the numbers on the tabs
Match up
• Can you match the name of the organ to
its picture and function in the body?
• Look carefully at the pictures…they may
not look as you expect!

Designing a model cell
• Draw your cell in your book – at least half
a page and in pencil
• Label the parts – level 4,5,6,
• Label the job that each part does – level
5,6
• Label what materials you are going to use
for each part and why

Explaining Cells
Learning objective: To be able to use success
criteria to help write an explanation.
Success Criteria:•Explain what level a piece of work should be
using criteria
•Use success criteria to level a piece of work
•Generate success criteria for an explanation
Explanation 1
The cell I modelled is a nerve cell. It is an animal cell
that is used to send messages through the body like if
you touched something hot and you moved your hand
away.
It still has all the normal parts of an animal cell
because it has a cell membrane, jelly-like stuff in the
middle and a nucleus. It is very long so that it is good
at its job because it could send a message from your
brain to your hand.
Explanation 2
I have made a model of a root hair cell. This is a specialised
plant cell that is found in the roots of the plant. A root hair
cell has the job of absorbing water and minerals from the soil
for the plant to use.
The cell is mainly like a normal plant cell but it does not have
any chloroplasts. Chloroplasts are used to absorb the suns
energy so because the root hair cell is under the ground it will
not see sunlight so does not need to have chloroplasts. The cell
also has an extended part to the cell which increases the
surface area. This makes the cell specialised because the
increased surface area means that it can absorb more water
and minerals for the plant.
The root hair cell also still has a cell membrane, cell wall,
cytoplasm, nucleus and a vacuole

Cell Division
Who’s the fastest?!
• Using plasticine, you are to start with 1
big cell and demonstrate cell division to
make 16 identical cells from it.
• You can’t just tear the 1 piece in to 16,
you have to do it properly i.e. half the
big one, then half each again and so on
until you have 16.
• Who can get 16 identical cells, made
properly in the fastest time?
What have you remembered?
• Have a go at completing the sheet you
have been given.
