- Animals and plants are

- Plants can survive the
winter as seeds.
- Some trees lose their
leaves in winter.
- Some animals survive the
winter by hibernating.
- Some birds escape winter
by flying to warmer countries.
- Green plants make their
own food by photosynthesis and are called producers.
- Herbivores are plant
eaters. Carnivores are meat eaters. Omnivores eat plants and meat.
- Food chains show what
animal eats and how energy is passed on.
- A food web is made of
many food chains.
- Microbes are tiny and are
found in air, soil and water.
- Microbes cause food to go

- Microbes include
bacteria, fungi and viruses.
- Microbes will grow in
nutrient broth and on agar jelly in petri dishes.
- Microbes will not grow in
sterile conditions.
- Ways to stop foods from
going bad.
- Microbes make dead things
rot and decompose.
- Microbes need air, water
and warmth to grow well.
- Things that rot are

What you should be able to do.
- Use a hand lens to
observe small animals.
- Find out how small
animals are adapted to their habitat.
- Avoid damaging animals
that you observe and return them to their habitat.
- Find out the name of some
small animals.
- Plan an investigation to
find out how well seeds survive frost.
- Write down some food
chains showing the direction in which the energy flows.
- Investigate the animals
found in leaf litter.
- Suggest some food chains
based on the animals collected.
- Make a slide of some
bread mould.
- Look at the bread mould
under a microscope.
- Investigate the growth of
microbes in sterile and non-sterile conditions.
- Plan an investigation to
find out what affects how quickly bread goes bad.
- Explain how plant
material is rotted down to form compost.
- Carry out an
investigation to find out which microbes rot grass.
