Grade 1 Science Games
These 24 free science games for grade 1 let kids predict what will happen, watch it play out and see why. They cover light, sound, earth & space, life science, human body, weather, ecosystems, plant science, health & the body, environment & climate, animal kingdom and run in the browser with no sign-up and no ads.
Each game shows the grade band it is written for, so you can pick the ones that fit your child.
Light
- ShadowsGrades 1–3Predict what a shadow does — move the lamp closer and it grows, because light travels straight.
- Can You See It?Grades 1–3Predict whether you can see in the dark — you only see when light bounces off a thing into your eyes.
- See Through It?Grades 1–3Predict whether light passes through — clear, blurry or blocked — and what shadow it casts.
Sound
Earth & Space
Life Science
Human Body
- The Five SensesGrades 1–3Predict which body part senses what — eyes see, ears hear, nose smells, tongue tastes, skin feels.
- TeethGrades 1–4Predict which tooth does which job — sharp incisors cut, pointy canines tear, flat molars grind.
- The SkeletonGrades 1–4Predict what bones do — they hold you up and shield soft organs: the skull guards the brain, ribs the heart.
Weather
Ecosystems
- Animal HabitatsGrades 1–4Predict where an animal belongs — each lives where its needs for food, water and shelter are met.
- Food Chain CrossingGrades 1–3Play Frogger as a rabbit, caterpillar, mouse or fox — hop across lanes of animals only when the one in your path doesn't eat you, because who is dangerous depends on where you sit in the food chain.
Plant Science
Health & the Body
- Food GroupsGrades 1–4Predict a balanced plate — fruits, veggies, grains, protein and dairy each do a job.
- Germs & HygieneGrades 1–4Predict how germs spread and what stops them — washing hands with soap breaks the chain.
- Exercise & FitnessGrades 1–4Predict what exercise does — a faster heart, harder breathing, and stronger muscles.
- Why We SleepGrades 1–4Predict what sleep does — the brain sorts memories and the body grows and repairs overnight.
Environment & Climate
Animal Kingdom
Common Questions
What science do kids learn in grade 1?
These 24 grade 1 science games cover Light, Sound, Earth & Space, Life Science, Human Body, Weather, Ecosystems, Plant Science, Health & the Body, Environment & Climate and Animal Kingdom. Each game isolates one big idea, such as why a heavy and a light object fall together or what makes a circuit light a bulb.
How do the predict-observe-explain games work?
The child first predicts what will happen, then watches the real thing play out, then reads a short explanation of why. Checking a guess against the result is what corrects common misconceptions, and it takes only a minute or two per round.
Are these grade 1 science games free?
Yes. Every game is free with no ads, no in-app purchases and no sign-up, and runs in any browser on a phone, tablet or computer.
How long should my child play each day?
Ten to fifteen minutes is plenty. One or two games per sitting, ideally followed by a quick chat about what surprised them or a real-life experiment at home, helps the idea stick.
