A - MOST CHILDREN WILL …•Recognise that there are many very small organisms which can cause illness or decay, or can be used in food production •Recognise that micro-organisms feed, grow and reproduce like other organisms

B - SOME CHILDREN WILL…•Recognise that very small living things can cause illness

C - SOME CHILDREN WILL … •Describe evidence that yeast is living•Explain how micro-organisms can move from one food source to another and how this can cause food-poisoning

In 1796 Edward JENNER

discovered how to make a vaccine to

treat a disease called

smallpox.He used a micro-organism called a

virus.

Vaccines and vaccination help us

to treat people.

Healthy people are given a tiny, but safe, dose of a usually harmful

germ.

This causes the body to produce

ANTIBODIES against a disease.

This is known as IMMUNISATION

Page 6: A - MOST CHILDREN WILL … Recognise that there are many very small organisms which can cause illness or decay, or can be used in food production Recognise.

In France in the 1800’s a scientist

called

Louis Pasteur

explored diseases caused

by

micro-organisms.

Some micro-organisms help us and some

harm us.

The banana is peeled. The peel is yellow and it looks white inside. It is

ripe and ready to eat!

Page 11: A - MOST CHILDREN WILL … Recognise that there are many very small organisms which can cause illness or decay, or can be used in food production Recognise.

The peel has gone darker, the inside is going yellow and it is starting to rot.

Page 12: A - MOST CHILDREN WILL … Recognise that there are many very small organisms which can cause illness or decay, or can be used in food production Recognise.

The peel has gone brown and now the inside is going brown too. It is really looking

bad and you wouldn’t want to eat it!

Page 13: A - MOST CHILDREN WILL … Recognise that there are many very small organisms which can cause illness or decay, or can be used in food production Recognise.

Now the peel has gone black and curled up, it is much smaller and drier. The inside is going darker and mushy.

The banana is attracting flies and you really wouldn’t eat it now!!!

Page 14: A - MOST CHILDREN WILL … Recognise that there are many very small organisms which can cause illness or decay, or can be used in food production Recognise.

Now the peel has really shrivelled up, the

inside is dry and wrinkly and it smells!

It is almost all black and it is much smaller than 2 weeks ago.

How long does it take for vegetable and plant waste to become soil?

When a living thing dies, it DECAYS

Micro-organisms, such as bacteria and fungi, help to rot dead plants

and animals.

When the bread is

baked the yeast is killed by the heat.

… and the bread rises

The carbon dioxide expands

How can micro-organisms help to

make bread?

Page 38: A - MOST CHILDREN WILL … Recognise that there are many very small organisms which can cause illness or decay, or can be used in food production Recognise.

YEAST is a micro-organism we use to

make bread.

It starts growing when it has sugar to feed on.

It gives off a gas when it grows.
