Can play help children understand science?

Watch a child play for ten minutes and you'll see a scientist at work.

She drops a stone into water and it sinks. She drops a leaf and it floats. She tries a bottle cap — it floats. She fills the bottle cap with sand — it sinks. She frowns, thinks, tries again. Without knowing the word "density," she's running an experiment.

Adults sometimes see play as the opposite of learning: "Stop playing and go study!" But decades of research suggest the opposite. For children, play is often how learning happens.

Can play really help children understand science — and how can parents and teachers use it without turning every game into a boring lesson?

What scientists say about play

Scientists who study how children learn — developmental psychologists — have found that young children naturally test ideas, much like scientists. Psychologist Alison Gopnik of the University of California, Berkeley, famously described babies and young children as "scientists in the crib." They form ideas about how the world works, test them through play and change their minds when the results surprise them.

The LEGO Foundation, together with researchers at Harvard and elsewhere, has described five features of "learning through play." Playful learning is:

• Joyful
• Meaningful (connected to real life)
• Actively engaging (hands and mind)
• Iterative (try, fail, try again)
• Socially interactive (with others)

Look at that list again. It also describes good science.

Guided play — where adults set up a playful activity with a learning goal — can help children learn as well as, or better than, direct instruction for some skills. (Skene et al., "Can Guidance During Play Enhance Children's Learning and Development?", Child Development, 2022 meta-analysis)

Why play works for science

Science is not a list of facts. It's a way of thinking: ask a question, make a guess, test it, observe, explain. Play trains exactly these habits.

• Curiosity. Play starts with "What happens if…?" That's a scientific question.
• Experimenting. Children repeat actions to see if they get the same result — that's replication.
• Failure without fear. In a game, failure is part of the fun. In science, failure is data.
• Explaining. Children love to explain their discoveries: "Look! If you roll the ball on the smooth floor, it goes further!" That's describing friction.
• Collaboration. Playing together means sharing ideas and arguing about results — just like scientists.

Joke break: A child asked her father why the sky is blue. He explained light scattering for ten minutes. She listened politely, then asked, "OK, but why is Grandma's car blue?" Science: 1. Dad: 0.

Examples: science hidden in everyday games

African childhood is full of games that teach science without a textbook:

• Ampe (Ghana) and similar jumping and clapping games: rhythm, patterns and quick counting.
• Awalé / Oware / Adji (played across West Africa, including Benin): a seed-sowing board game that trains counting, strategy and prediction. Mathematicians have studied the game's strategies. It's basically maths with seeds.
• Spinning tops and homemade wheels: balance, rotation, friction.
• Kites made of plastic bags and sticks: wind, lift, balance.
• Homemade wire cars (common across Africa): design, engineering and mechanics. Children plan, bend, adjust and test until the car rolls straight.
• Clay modelling: materials, water, drying and heat.

Every one of these is a science lesson waiting for a good question.

The role of adults: guide, don't take over

Research shows that pure free play is valuable, but "guided play" often works best for specific learning goals. In guided play, an adult sets up an environment or challenge, then lets children explore, asking questions along the way.

Good guiding questions:

• "What do you think will happen?"
• "Why do you think that happened?"
• "What could we change?"
• "How could we find out?"
• "Is there another way?"

What to avoid:

• Giving the answer too quickly.
• Correcting every "wrong" idea immediately. Let children test it.
• Turning the game into a test.

Educational games and toys made in Africa

A new generation of African creators is designing games that teach. In Benin, Glim designs educational games for children and families with the motto "Jouer pour se cultiver" (play to learn about your culture). Their work shows how games can teach history, culture and thinking skills while being fun. Read more in What Practical Learning Looks Like: Glim Education and the Power of Play.

Across the continent, others create board games, card games, puzzles and apps based on African history, geography and science. When children see their own world in a game, learning becomes more meaningful. For more on cultural stories, read What stories should African children grow up hearing?.

7 playful science activities you can do today

No lab needed. Most materials are already at home or school.

Materials: a basin of water, 10 small objects. Play: Guess, test, sort into two piles. Then try to make a floating object sink (and vice versa). Science: density and buoyancy.

• Sink or float

Materials: sunlight or a torch, hands and objects. Play: Make animal shadows. Move closer and further from the light. Science: light travels in straight lines; distance changes shadow size.

• Shadow game

Materials: a board or book, small toy cars, bottle caps, balls. Play: Race objects down a ramp. Change the height. Add cloth or sand. Science: gravity, friction, speed.

• Ramp race

Materials: a balloon, string, a straw, tape. Play: Thread the string through the straw, tape the balloon, let it go. Science: action and reaction (Newton's third law).

• Balloon rocket

Materials: purple cabbage or hibiscus (bissap) water, lemon, soap, baking soda. Play: Add different liquids and watch colours change. Science: acids and bases. Bissap is a great local indicator.

• Colour-changing juice

Materials: beans, cotton or tissue, cups, water. Play: Grow beans in different places — dark, light, dry, wet. Science: what plants need to grow.

• Seed detectives

Play a game, then ask: "Can you predict where the last seed will land?" Science and maths: counting, prediction, strategy.

• Awalé counting challenge

Play in the classroom (even with 60 students)

Teachers often say: "Play is nice, but I have a big class and a big syllabus." Here are ways to include play without losing time:

• Start with a 5-minute playful demonstration, then connect it to the lesson.
• Use group challenges: "Build the tallest paper tower in 10 minutes."
• Turn revision into games: quizzes, card matching, riddles.
• Let students design games about the topic.
• Use role-play: students act as planets, molecules or parts of a cell.

What about screens and video games?

Some digital games can support science learning — for example, simulations where children change variables and see results, or building games that involve planning and design. Coding games also teach logic (see What a first coding lesson can teach a child).

But screens shouldn't replace hands-on play. The World Health Organization recommends limiting sedentary screen time for young children and encouraging active play. A good balance: some screen games with a learning goal, and plenty of physical, messy, real-world experiments.

A note for parents: messy is good

Many parents worry about mess. Water on the floor. Sand in the house. Seeds everywhere. But mess is often a sign of learning. A few tips:

• Choose a "science corner" outside or on a mat where mess is allowed.
• Keep a box of free materials: bottles, caps, cardboard, string, straws, old spoons, plastic containers.
• Give children a small notebook to draw what they discover.
• Let them clean up too — that's responsibility training.
• Show interest. Children play longer and think deeper when an adult asks, "Tell me what you found."

Joke break: One mother said her son wanted to test whether the family's cat floats. The answer: no experiments on animals — and no experiments on little brothers either. Science has rules.

How to know if play is working

How do you know whether children are actually learning while they play? Watch for these signs:

• They ask more "why" and "what if" questions.
• They make predictions before testing.
• They use new words: "heavier," "faster," "floats," "melts."
• They repeat experiments to check.
• They explain their thinking to others.
• They connect games to real life: "That's like when the canoe floats!"

Teachers can use a simple checklist with these signs to track progress, instead of only paper tests. If you want to measure progress more formally, read How to measure whether an initiative helped.

Play for older children too

Play isn't only for toddlers. Teenagers learn through play as well — in different forms: strategy games, building challenges, escape-room puzzles, science competitions and robotics tournaments. A group of 15-year-olds trying to build the strongest paper bridge is playing. So is a robotics team testing a robot at midnight before a competition (see What happens inside a robotics team before a competition).

The answer: yes — with a little help

Can play help children understand science? Yes. Research, experience and common sense agree. Play builds curiosity, experimenting, persistence and explanation — the heart of science.

The trick is not to choose between play and learning, but to combine them. Give children materials, time, freedom and good questions. They will do the rest.

Next time you see a child dropping stones in water or building a wire car, don't say "Stop playing." Ask, "What did you discover?"
