KS1 Science — Animals, Plants, Materials & Seasons

KS1 science should mostly happen outdoors, or with real things in your hands. A five-year-old learns what a leaf is by holding one — nothing here needs a worksheet, and most of it needs no equipment at all. Working scientifically, animals, the human body, plants, habitats, materials and the seasons, with questions a child can answer by talking, drawing or pointing.

What a child will be able to do

Working scientifically

Living things

Materials and seasons

All the teaching and questions below are free to read and print. The answer key, the common-mistakes guide and the teaching notes are PawSteps Premium.

Part 1 — Working scientifically

Science at this age is noticing.

The five things scientists do

WhatHow it sounds
Ask"I wonder why…"
Look carefully"What can you see?"
Sort"Which ones go together?"
Notice patterns"It always happens when…"
Say what you found"We found out that…"
💡 The most valuable question — "How do you know?"

Not to catch a child out — to make them point at the evidence. "It's a mammal.""How do you know?""It's got fur." That second answer is science. The first is just a label.

Sorting

Sorting is the main scientific skill of KS1. Give a child a pile of things and ask them to put them into groups. Then ask why those groups. There is often no single right answer, and that's the point. Animals could be sorted by:

All of these are valid. The skill is choosing a rule and sticking to it.

Recording without writing

Small children shouldn't have to write to do science.

Instead of writingDo this
A results tableSort real objects into hoops or trays
A written conclusionSay it out loud, and the adult writes it down
A labelled diagramDraw and point, adult adds the words
A tally chartStick a sticker or a cube in a column

Part 2 — Animals

Sorting animals into groups

GroupWhat they haveExamples
MammalsFur or hair, drink milk as babiesHedgehog, guinea pig, rabbit, dog, human
BirdsFeathers, beak, wings, lay eggsParrot, robin, chicken
ReptilesDry scaly skin, lay eggsBearded dragon, tortoise, snake
AmphibiansWet skin, live in water and on landFrog, toad, newt
FishLive in water, scales, finsGoldfish, shark
MinibeastsSmall, no bones insideSpider, snail, worm, beetle
Sorting the animals you know
AnimalGroupHow you can tell
HedgehogMammalIt has fur — spines are special hairs
ParrotBirdFeathers and a beak
TortoiseReptileDry scaly skin and a shell
FrogAmphibianWet skin, lives in and out of water
GoldfishFishLives in water, has fins
SpiderMinibeastEight legs, no bones inside

What animals eat

TypeEatsExamples
HerbivorePlants onlyRabbit, tortoise, guinea pig
CarnivoreMeat onlyCat, snake, owl
OmnivorePlants and meatHuman, hedgehog, fox
A memory hook

Herbivore — herbs are plants. Carnivore — carnival, carnage… meat. Omni means "all".

What animals need to stay alive

Four things. Every animal. Always.

Food · Water · Air · A safe place to live

Activity: look at any animal and find all four. "Where's his water? Where does he sleep? What does he eat?"

Babies and grown-ups

Baby animals grow into adults, and many have their own name.

AdultBaby
HedgehogHoglet
RabbitKitten
Guinea pigPup
CatKitten
DogPuppy
FrogTadpole
ButterflyCaterpillar
BirdChick

Some babies look like their parents. Some don't at all. A hoglet looks like a small hedgehog. A tadpole looks nothing like a frog. That change is called metamorphosis, and it is genuinely worth knowing at six.

Part 3 — The human body

Parts of the body

Head · neck · shoulders · arms · elbows · hands · fingers · chest · tummy · back · legs · knees · feet · toes

On the face: eyes, ears, nose, mouth, hair, eyebrows, chin, cheeks

The five senses

SenseBody partWhat it does
SightEyesSee
HearingEarsHear
SmellNoseSmell
TasteTongueTaste
TouchSkinFeel
Investigations for each sense

Touch: feely bag. Reach in without looking. Describe before you pull it out.
Hearing: close your eyes. What can you hear? Rustling, chewing, a wheel turning.
Smell: sniff jars — hay, lemon, mint. Which is which?
Sight: spot the difference between two pictures.
Taste: sweet, salty, sour — but check for allergies first, every time.

Animal senses are different from ours

AnimalBest senseWhy
HedgehogSmell and hearingComes out at night, can't see well in the dark
ParrotSightFlies, and needs to see food and danger from far away
SnakeSmell — with its tongueTastes the air to find prey
BatHearingUses sound to find its way in the dark
The question to ask — "Why does a hedgehog need such a good nose?"

Because it's dark when it's awake, so eyes are not much use. That is a six-year-old reasoning about adaptation, and it's the same thinking as GCSE.

Staying healthy

What we needWhy
Different kinds of foodDifferent foods do different jobs
ExerciseKeeps the body strong
SleepLets the body rest and grow
WashingStops germs spreading
⚠️ Wash your hands after touching any animal

Every time. Before eating especially.

Part 4 — Plants

Parts of a plant

PartJob
RootsHold the plant in the ground and drink up water
StemHolds the plant up and carries water
LeavesMake food for the plant using sunlight
FlowerMakes seeds so new plants can grow

What plants need

Light · Water · Air · Somewhere to grow (soil) · Warmth

The investigation to do

Four pots. Four seeds. Same soil, same start.

PotWhat it gets
1Everything — light, water, warmth
2No light — in a cupboard
3No water
4Kept cold

Look every day for two weeks. Draw what you see.

Why this one matters

It's a fair test — one thing changed for each pot, everything else the same. That's the whole method of science, and a five-year-old can do it with cress seeds and yoghurt pots. Also: the plant in the cupboard usually grows pale and floppy rather than dying, which surprises children and is worth talking about.

Trees

TypeWhat happens
DeciduousLoses its leaves in autumn — oak, beech, horse chestnut
EvergreenKeeps its leaves all year — pine, holly, fir

Wild plants and garden plants

Wild plants grow on their own — daisy, dandelion, buttercup, nettle. Garden plants are planted by people — rose, sunflower, tulip.

Go outside and find three.

Draw them. Name them if you can. Notice the differences.

Part 5 — Habitats

A habitat is the place where an animal or plant lives.

HabitatWho lives there
WoodlandSquirrel, owl, hedgehog, beetle
PondFrog, fish, dragonfly, pond snail
SeashoreCrab, seagull, limpet
GardenWorm, robin, snail, hedgehog
DesertCamel, lizard, scorpion
ArcticPolar bear, penguin, seal

Why animals live where they live

Because everything they need is there. A frog lives near a pond because it needs water for its skin and to lay its eggs. A hedgehog lives in a garden or hedgerow because there are insects to eat and leaves to hide in.

Microhabitats

A microhabitat is a very small habitat inside a bigger one.

The best activity in this whole unit — lift a log or a stone in a garden and look underneath

Woodlice, worms, beetles, centipedes, spiders. A whole world under one stone. Put it back exactly as you found it. That's their home.

Food chains

A food chain shows who eats what.

leaf → caterpillar → bird grass → rabbit → fox plant → slug → hedgehog

The arrow means "is eaten by." It always points towards the eater — that's the direction the energy goes.

⚠️ The mistake to head off early

Children draw the arrow the wrong way round because they think it means "eats." It means "is eaten by." Say it out loud when you draw it: "The leaf is eaten by the caterpillar."

Part 6 — Materials

Everyday materials

MaterialWhat it's likeMade into
WoodHard, strong, from treesTable, pencil, hutch
PlasticLight, waterproof, bendy or hardBowl, toy, bottle
MetalHard, shiny, coldSpoon, coin, key
GlassHard, see-through, breaksWindow, jar
FabricSoft, bendyClothes, blanket
PaperLight, tears, soaks up waterBook, bedding
RubberBendy, stretchy, grippyBoots, tyre, band

Describing materials

hard / soft · rough / smooth · bendy / stiff · shiny / dull · see-through / not · heavy / light · waterproof / soaks up water

Activity — the sorting tray

Collect ten objects. Sort them by material. Then sort them again a different way — by whether they're hard, or waterproof, or shiny. Same objects, different rule. That's classification.

Choosing the right material

Things are made of what they're made of for a reason.

ObjectMaterialWhy
WindowGlassYou can see through it
WelliesRubberWaterproof
SpoonMetalHard and easy to clean
BlanketFabricSoft and warm
Water bowlMetal or potteryHeavy so it can't be tipped over
The question — "Why isn't a window made of wood?"

Because you couldn't see through it. Children find this obvious and then realise they've just explained a property.

Changing materials

Some materials can be changed by squashing, bending, twisting or stretching.

MaterialWhat you can do
PlaydoughSquash, roll, twist
Elastic bandStretch
PaperBend, fold, tear
Metal spoonNothing — it's too stiff

Some changes can be undone — a bent piece of paper can be flattened. Some can't — a torn piece of paper cannot be untorn.

Part 7 — Seasons

SeasonWeatherWhat you see
SpringGetting warmer, showersBuds, blossom, baby animals, birds nesting
SummerWarm, sunny, long daysGreen leaves, flowers, insects everywhere
AutumnCooler, windy, rainLeaves change colour and fall, berries, conkers
WinterCold, frost, short daysBare trees, no insects, some animals sleeping

Day length

Summer days are long. Winter days are short. In winter it is dark when you get up and dark when you come home. In summer it is still light at bedtime.

What animals do in winter

WhatMeaningWho
HibernateSleep through the winterHedgehog, dormouse, bat
MigrateFly somewhere warmerSwallow, swift, cuckoo
StayCarry on, find what food they canRobin, fox, squirrel
⚠️ About hibernation — wild hedgehogs hibernate, African pygmy hedgehogs must not

Pet hedgehogs come from a hot country and never evolved to hibernate. If they get too cold they will try to, and it can kill them. This is why they need a heater on all winter. It's the single most important thing about keeping one, and it's a seasonal science fact that a six-year-old can understand.

Keeping a weather diary

Every day for a week: is it sunny, cloudy, rainy or windy? Hot or cold? Draw a symbol. Then count them up at the end.

That's data collection

And it's the beginning of everything.

Answers

Animals

1. Any three: hedgehog, rabbit, guinea pig, cat, dog, mouse, fox. 2. A bird — it has feathers, a beak and wings. 3. Food, water, air, a safe place to live. 4. A hoglet. 5. Herbivore — it only eats plants. 6. Any: frog, fish, dragonfly, pond snail, newt.

The human body

7. Sight, hearing, smell, taste, touch. 8. Your nose. 9. Because it comes out at night when it is dark, so its eyes are not much use — it finds food by smell. 10. Any three: eating different foods, exercise, sleep, washing hands, brushing teeth.

Plants

11. Roots, stem, leaves, flower. 12. Light, water, air, soil, warmth. 13. It grows pale and floppy, or does not grow well (accept: it dies). 14. Any: oak, beech, horse chestnut, sycamore.

Habitats

15. The place where an animal or plant lives. 16. Any two: squirrel, owl, hedgehog, beetle, deer, fox. 17. Under a log or a stone — somewhere dark and damp. 18. Any correct chain with arrows pointing towards the eater, e.g. leaf → caterpillar → bird.

Materials

19. Any three: spoon, key, coin, tin, fork, nail. 20. Because you can see through it — glass is transparent. 21. Any: wellington boots, a raincoat, plastic, an umbrella. 22. No — that change cannot be undone.

Seasons

23. Spring, summer, autumn, winter. 24. Autumn. 25. To sleep through the winter. 26. Because it comes from a hot country and never learned to hibernate — if it gets cold it will try to, and that can make it very ill.

The mistakes to watch for

Saying an animal is a mammal without saying how you know. Always follow with "how do you know?"

Food chain arrows the wrong way. The arrow means "is eaten by," so it points at the eater.

Thinking spines mean a hedgehog isn't a mammal. Spines are special hairs. It has fur, so it's a mammal.

Saying a plant in the dark will die. It usually grows pale and weak first, which is more interesting and more accurate.

Thinking all pets hibernate. Wild hedgehogs do. Pet African pygmy hedgehogs must not, and it matters.

Sorting without a rule. Ask what the rule was. "These ones" is not a rule.

Teaching notes

Do it outside. Habitats, plants, seasons and minibeasts are all outside. Twenty minutes in a garden beats an hour of pictures.

"How do you know?" is the whole of KS1 science. It turns a label into evidence, and it's the same question a GCSE examiner is asking in a more complicated way.

Sorting is the main skill, and there's rarely one right answer. Let children choose their own rule and then explain it. That's more scientific than filling in a pre-made table.

Don't make them write. A five-year-old who has to write down what they found spends all their effort on the writing and none on the science. Let them talk, draw, sort real objects, and have an adult scribe.

The log-lifting activity is the best thing in this unit. Woodlice, worms, centipedes, a whole world under one stone. Put it back carefully afterwards — that's a lesson too.

The hedgehog hibernation point is genuinely important, not just interesting. Any family keeping an African pygmy hedgehog needs to know it, and a child who understands why is more likely to notice if the heating fails.

Fair tests can start now. The four-pot plant investigation is a proper controlled experiment and a five-year-old can run it. Everything in KS2, KS3 and GCSE science builds on that one idea.
