Sort pictures of plants and animals– either criteria given by teacher or their own criteria.
Collect minibeasts (from leaf litter, ponds?). Sort into sets.
Sort leaves according to shape? colour?
Look at plants around school – identify similarities and differences.
Discuss features of different animals e.g. wings, tails, shells etc.
Make a collection of animals (include fish, birds, insects)
Pass a picture of an animal round and ask each child to make a comment about it. Then
pass 2 pictures round and get them to identify a similarity or difference.
Make “What am I?” cards to get children to identify animal e.g. I have two legs, two wings,
a beak, feathers, webbed feet etc.

Survey the school grounds/park and record what is found there.
Look at pictures of farm, park, field etc and talk about what is found there.
Draw pictures of what they would expect in a pond, under a log, on a tree? etc.
Shake branches onto a white sheet. Use a paintbrush to collect minibeasts.
Go on a scavenger hunt to find for example – something soft, crunchy, prickly, shiny?
Set up mini-environment in the classroom e.g. wormery, brine shrimps
Make a collage of all the different places plants live.
Blindfold children to make friends with a tree – using sense of touch.
Study two contrasting environments – look at the plants and animals found there.
Look at different types of birds’ feet/beaks – link to lifestyle.

Give a series of clues to guess the plant or animal e.g. animal has smooth skin, lives in a
pond and lives on land, jumps etc.
Hang different coloured wool, pieces of material outside which the children have to find.
Discuss which were the easiest to find.
Match a description to a particular plant or animal.
Play ‘the odd one out’ – child picks 3 plant/animal pictures and others have to say why it is
the odd one out.
Find out how many legs minibeasts have.
Use simple keys with pictures and animals in simple groups e.g. no legs, with wings,
without wings, so that children can pick on an obvious characteristic.
Use pictures of minibeasts and group in different ways.
Use simple computer programmes e.g. “Pond Life”
Go pond dipping and identify “beasties”.
Go on a flower hunt or leaf hunt e.g. find a tree flower, grass flower, pink flower, flower on
ground etc.
Use keys devised by children the year before.
Play “What am I?” – give information but no picture and use a simple key to name.
Play ‘animal opposites’ – name an animal that is very different to the one give – include a
wide range of animals on the list.
Play ‘plant opposites’ – use trees, vegetables, ferns, mosses, bushes, water plants, wild
and garden plants.
Give children plants and animals to sort according to named groups e.g. 4
legs, 2 legs, no legs or a type of group

Look at/research adaptations of animals e.g. birds feet and beaks, arctic and desert
animals.
Look at/research adaptations of plants e.g. in desert, in water.
Discuss camouflage. Design plants and animals to blend in to different backgrounds.
Take a particular plant/animal. Ask children to draw/write what it needs to live and where
those things come from. Discuss
Discuss some different foods animals eat, where the food comes from and if they eat other
things and why.
Is possible use first-hand observation when studying a habitat or look for evidence of
“eating” and discuss with children.
Discuss what would happen if something in a food chain died out for some reason.
Sort animals by skin type; leg type; habitat; size.
Sort plant by leaf type; habitat; size.
Play 20 Questions – to which the answer can only be “Yes” or “No”.
Use commercial keys to identify plants and animals
Make a key to identify the class.
Let children construct simple branching keys – limit the number of specimens until
confident with idea.
Construct simple “Go to” keys from a simple branching key.
Identify plants and animals from different habitats but also record the features of where it
was found. Link features to habitat.
Find out how animals can protect themselves, e.g. camouflage, warning markings, smells,
rolling into a ball, changing coat colour in winter.
Classify animals into vertebrates and invertebrates
Use pictures of plants and animals to devise food chains. Pupils could be labelled and act
out different organisms in a food chain.
Construct simple food web using pupils (labelled as organisms) and lengths of string.
Construct simple food web using pictures and lengths of string.
Discuss the interdependence of plants and animals in food chains and food webs.
Look at how animals adapt to seasonal and daily changes in their environment e.g.
hibernation, migration, nocturnal animals, moulting and colour changes.

What food do snails or woodlice prefer?
Do all insects have 6 legs?
Are all leaves green?
Do all spiders have 8 legs?
Are all wood lice the same?
Do birds prefer brown or white bread?
Are all soils the same e.g. appearance, holding water, texture?
Are all rocks the same e.g. hardness, permeability?
Where are most minibeasts found e.g. on leaves, bark, under stones, in soil
Are the same minibeasts (or plants) found in ponds or streams?
What do woodlice like to eat e.g. wood bark, paper – any particular type, bread, fruit, leaves etc?
Which leaves do caterpillars like?
How much does a caterpillar eat?
Do all snail have rings or bands on their shells? Is there a link to colour of shell, habitat, the way the shell coils etc?
