KS1 Scientific Enquiry Outdoor Learning Activities
Looking for simple KS1 scientific enquiry activities you can take outside? Outdoor science is one of the easiest ways to help children ask questions, observe closely, test ideas, compare, sort, measure, record and explain what they notice. Are you new to outdoor learning explore this article to learn more : What is Outdoor Learning?
Scientific enquiry in KS1 does not need to feel complicated. Children do not need a full science lab or lots of equipment. The school grounds, playground, field, garden, trees, puddles, soil, sticks, stones, leaves, shadows, water and weather can all become powerful starting points for enquiry.
At The Muddy Puddle Teacher®, we believe science should feel practical, curious and meaningful. Young children are natural scientists. They wonder why puddles disappear, why leaves change colour, which material is strongest, where worms live, how shadows move and what plants need to grow. Outdoor learning gives children real things to investigate. Download this resource and 1000’s more – take a 60-day free trial.

If scientific enquiry feels overwhelming, start with one question.
You do not need to plan a huge investigation. Choose something children can observe, compare or test outside. You might ask which surface is warmest, which material is waterproof, where do we find the most minibeasts, which object rolls furthest, which plant has the biggest leaves or how do shadows change during the day?
In KS1, scientific enquiry is about helping children think like scientists. They need to ask simple questions, look carefully, use equipment where appropriate, make observations, compare what they find and talk about their results.
The key is to keep it simple and practical. Children learn science best when they can see it, touch it, test it and talk about it.

Which Surface Holds the Most Water?
Take children outside after rain or use small amounts of water safely. Ask them to compare different outdoor surfaces, such as grass, soil, paving, tarmac, wood, leaves or fabric. Children can predict which surface will hold water, which will absorb it and which will let it run away.
Time: 20–30 minutes
Prep: Low
Resources: Small cups of water, clipboards, chalk, natural surfaces and adult supervision
Learning: Observation, prediction, materials, comparing, recording and explaining
As children investigate, ask questions such as, what do you think will happen, where did the water go, which surface stayed wet, which surface absorbed the water, which surface was waterproof, how do you know?
This gives children a quick KS1 scientific enquiry success and helps them understand that science is about asking questions and noticing what happens. Find more ideas in the KS1 Outdoor Learning Hub.
What Is Scientific Enquiry in KS1?
Scientific enquiry in KS1 means helping children learn how to work scientifically. Children ask questions, observe, compare, sort, group, measure, test, record and talk about what they find out.
At this age, scientific enquiry should be practical and accessible. Children might not always write a full method or conclusion, but they can still think scientifically. They can predict, notice patterns, compare results and explain their ideas using simple language.
Outdoor learning is perfect for KS1 scientific enquiry because it gives children a real-world context. They are not just talking about plants, weather, materials, animals or light. They are seeing those things in front of them.
Outdoor Scientific Enquiry Questions for KS1
A good enquiry question is simple, practical and possible to explore outdoors.
You might ask which material makes the best shelter, where do plants grow best, which object rolls furthest, what happens to ice outside, which area has the most minibeasts, how does a shadow change, which surface is safest after rain, what do seeds need to grow, which natural object is heaviest, how does water move across the playground?
These questions encourage children to predict, test, observe and explain. They also help children understand that science starts with curiosity.
Try to use questions that children can investigate for themselves, not questions where the adult simply tells them the answer.
KS1 Scientific Enquiry and Plants
Plants are one of the best topics for outdoor scientific enquiry.
Children can observe plants, compare leaves, look for roots, stems and flowers, measure growth, record changes over time, identify where plants grow best and investigate what plants need.
They might compare plants growing in the shade and sun, count flowers in different areas, observe how a seedling changes each week or compare leaf shapes.
Ask questions such as, where are the plants growing well, which plant has the biggest leaves, what do plants need to stay healthy, how has this plant changed, why do you think this plant is growing here?
This helps children build observation skills and understand living things in a real setting.
KS1 Scientific Enquiry and Materials
Outdoor spaces are full of materials children can investigate.
Children can compare natural and man-made materials, test whether objects are waterproof, explore which materials are strong, flexible, rough, smooth, heavy or light, and decide which materials would be best for a particular purpose.
They might test which material would make the best roof for a toy shelter, which object floats or sinks, which surface is slippiest after rain or which material keeps something dry.
This makes materials learning purposeful. Children are not just naming properties. They are using those properties to solve problems.
KS1 Scientific Enquiry and Weather
Weather is a brilliant starting point for KS1 enquiry because it changes all the time.
Children can observe rain, wind, sun, clouds, shadows, puddles, temperature and seasonal changes. They can keep a simple weather diary, compare shady and sunny areas, observe how puddles change, make wind streamers or investigate where the playground feels warmest.
Ask questions such as, where is the windiest place, which puddle will disappear first, how do shadows change, which area feels coolest, what happens to the ground after rain?
Weather enquiry helps children understand the world around them and connect science to everyday life.
KS1 Scientific Enquiry and Minibeasts
Minibeasts create wonderful opportunities for careful observation and enquiry.
Children can look for minibeasts in different habitats, compare where they are found, observe how they move and discuss what they need to survive. They might investigate whether more minibeasts are found under logs, near leaves, in soil, on plants or in damp areas.
It is important to teach children to be gentle and respectful. Minibeasts should be observed carefully and returned to where they were found.
Questions might include, where did we find the most minibeasts, why do woodlice like damp places, how does a worm move, what do minibeasts need, how can we make a safe habitat?
This supports science, empathy and care for nature.
KS1 Scientific Enquiry and Forces
Forces can be explored outdoors through movement, ramps, rolling, pushing, pulling, sliding and balancing.
Children can investigate which object rolls furthest, which surface makes a toy car go faster, whether a steeper ramp changes the distance travelled or which objects are easiest to push or pull.
You might use planks, crates, toy cars, balls, hoops, sticks, cones and chalk marks.
Ask questions such as, which ramp made the car travel furthest, what happened when the ramp was higher, which surface slowed the object down, did the heavier object travel further, how can we make it fair?
This helps children begin to understand fair testing in a practical way. Find more ideas in the KS1 Outdoor Learning Hub.
How to Record Scientific Enquiry Outdoors
Recording in KS1 does not always need to mean long writing.
Children can record by drawing, taking photographs, making tally marks, using simple tables, placing objects in groups, making chalk marks, using stickers, talking to an adult or creating a class chart.
For example, if children are investigating minibeasts, they might make a tally of what they find. If they are comparing materials, they might sort them into waterproof and not waterproof. If they are observing plants, they might draw the same plant each week.
The aim is to help children show what they noticed and begin to explain what they found out. Download this resource and 1000’s more – take a 60-day free trial.

Scientific Vocabulary for KS1
Outdoor enquiry gives children a real reason to use scientific vocabulary.
Useful words include observe, question, predict, test, compare, sort, group, measure, record, result, change, same, different, fair, material, waterproof, absorb, living, habitat, plant, root, stem, leaf, flower, seed, shadow, temperature, force, push, pull, float and sink.
Adults can model vocabulary naturally during the enquiry. For example, let’s observe carefully, what do you predict will happen, how can we make this test fair, what did you notice, how could we record our results?
This helps children begin to speak like scientists.
Scientific Enquiry for Children Who Need More Support
Some children may find scientific enquiry challenging because it involves language, attention, prediction, recording or waiting for results.
Outdoor enquiry can help because it is practical, visual and active. Children can point, sort, move, touch, draw, choose, match and talk rather than relying only on writing.
Keep instructions short. Focus on one question at a time. Use visuals, real objects and repeated routines. Children might follow a simple pattern such as predict, test, notice, talk.
For some children, being outside reduces pressure and makes science feel more engaging.
Scientific Enquiry for Greater Challenge
For children who are ready for more challenge, encourage them to plan parts of the enquiry themselves.
They might choose what to test, decide how to record results, think about how to make the test fair, compare results between groups or explain why something happened.
You could ask questions such as, how could we make this investigation more accurate, what would you change next time, did anything surprise you, can you explain your result using scientific vocabulary, what new question do you have now?
This helps children move from doing activities to thinking more deeply as scientists. Looking for more Outdoor Science Ideas try Food Chains KS1 Lesson Ideas Outdoors.
