Each game shows the grade band it is written for, so you can pick the ones that fit your child.
Matter
- States of MatterGrades 2–4Predict what happens when you heat ice or cool water — solid, liquid and gas, transformed.
- Can You Undo It?Grades 2–4Predict whether a change can be reversed — melting can; burning makes something new.
- DissolvingGrades 2–5Predict what makes sugar dissolve faster — and that it does not vanish, just spreads out.
Magnets
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
- What Plants NeedGrades 1–3Predict what happens — with light and water a plant thrives; take one away and it wilts.
- Life CyclesGrades 2–4Predict the next stage — a caterpillar becomes a chrysalis, then a butterfly.
- CamouflageGrades 2–4Predict which animal is hidden — colors and patterns that match the surroundings help animals hide.
- Living or NotGrades K–2Things pop out of holes like Whac-A-Mole — bonk only the living ones (plants too!), and anything that can't eat or grow tells you why.
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.
- BreathingGrades 2–5Predict what breathing does — take in oxygen, breathe out carbon dioxide; the lungs puff up and shrink.
Weather
- Cloud TypesGrades 2–5Predict the cloud and its weather — puffy, flat, wispy or towering, each signals fair or stormy skies.
- Rain, Snow & HailGrades 2–5Predict what falls — the temperature of the air decides rain, snow, sleet or hail.
- Reading a ThermometerGrades 1–4Predict warmer or cooler — read the thermometer and tell what to expect or wear.
Ecosystems
- Animal HabitatsGrades 1–4Predict where an animal belongs — each lives where its needs for food, water and shelter are met.
- PollinationGrades 2–5Predict the pollinator’s work — carrying pollen flower to flower so plants can make seeds and fruit.
- 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
- Plant PartsGrades 1–4Predict each part’s job — roots drink, the stem carries, leaves catch sunlight, the flower makes seeds.
- Plant Parts We EatGrades 2–5Predict which part you eat — a carrot is a root, celery a stem, broccoli a flower, an apple a fruit.
- Seed DispersalGrades 2–5Predict how a seed travels — on the wind, by water, hitching on an animal, or popping out.
- GerminationGrades 1–4Predict what a seed needs to sprout — water and warmth; the root heads down, the shoot up.
- Roots & WaterGrades 2–5Predict which way water moves — up from the roots, through the stem, out to the leaves.
Geology
Cells & Microbiology
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.
- Vitamins & MineralsGrades 2–5Predict the nutrient — vitamin A for eyes, C to fight colds, calcium for bones, iron for blood.
- White CellGrades 2–4Steer a white blood cell through a blood vessel and engulf the germs and virus-infected cells before they multiply, while leaving your own red cells, platelets and healthy cells alone.
Environment & Climate
- RecyclingGrades 1–4Predict the right bin — recycle, compost or trash — and what a recycled item becomes.
- PollutionGrades 2–5Predict the type — air, water or land — and how to clean it up and keep it clean.
- ConservationGrades 2–5Predict waste or save — small actions save water, energy and materials we can’t replace.
- Reduce, Reuse, RecycleGrades 1–4Predict the best R — reducing and reusing beat recycling; put the three in order.
- Recycling RushGrades 2–4Hop between four conveyor belts and slide each item to the bin for what it is made of — paper, plastic, metal, glass or compost — before it reaches the landfill.
Oceans & Marine Life
Extreme Weather & Sky
Space Exploration
Genetics & Heredity
Making Electricity
Motion & Forces
Animal Kingdom
- Insect MetamorphosisGrades 2–5Predict the stage — egg to caterpillar to chrysalis to butterfly, a full-body change.
- Animal MigrationGrades 2–5Predict the journey — animals travel with the seasons to find food, warmth and a place to raise young.
- HibernationGrades 1–4Predict the big sleep — some animals slow right down through winter to survive the cold.
- Animal SensesGrades 2–5Predict the super-sense — a dog’s nose, an eagle’s eyes, a bat’s echolocation.
- Nocturnal AnimalsGrades 1–4Predict day or night — owls and bats work the night shift with big eyes and sharp hearing.

Common Questions
What science do kids learn in grade 2?
These 62 grade 2 science games cover Matter, Magnets, Light, Sound, Earth & Space, Life Science, Human Body, Weather, Ecosystems, Plant Science, Geology, Cells & Microbiology, Health & the Body, Environment & Climate, Oceans & Marine Life, Extreme Weather & Sky, Space Exploration, Genetics & Heredity, Making Electricity, Motion & Forces, Animal Kingdom, Light & Optics, Body Systems and Science Skills. 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 2 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.
