Biology games for kids: plants, animals and the human body
These biology games for kids explore the living world, from a single leaf to the inside of the lungs. Many questions are asked on pictures based on real scientific illustrations: children find the parts of a flower, a cell, a tooth or the skeleton on the picture itself.
Topics include the parts of plants and flowers, animal groups, life cycles and the water cycle, plant and animal cells, the heart and the eye, food chains and food webs, teeth and digestion, the skeleton, joints and muscles, and how breathing works. The games are made for ages 7 to 12, and most levels start with a short explanation before the questions.
The games, one by one
Verdant Trail
Ages 7–12 · 10 levels
A trail through the living world: the parts of a plant and of a flower, sorting animals into their groups, putting life cycles in order, the water cycle, what is inside plant and animal cells, and how the human heart and eye are built.
Sunthread Run
Ages 8–12 · 16 levels
Follow the Sun's energy from a leaf through food chains and into the body. Children sort producers and consumers, build food chains, learn the types of teeth and what is inside one, follow food through the digestive system and predict what happens when a food web changes.
Windspine Citadel
Ages 8–12 · 18 levels
Bring a giant citadel back to life by learning how the body moves and breathes: the bones of the skeleton and the organs they protect, joints, tendons and muscle pairs, then the path of air through the nose, windpipe and lungs to the tiny air sacs where oxygen enters the blood.
How levels work, and what is free
Every game is a trail of levels that get harder as they go. Each level has its own guardian, and every right answer wears it down. Fast answers earn bonus points, but only accuracy counts for the rest: up to three stars show how many answers were right, and the next level opens once at least 60% of the answers in the one before it were right.
Levels 1 and 2 of every game can be played straight away, with no account. Levels 3 and 4 need a free account. From level 5 on, levels are part of the subscription. The games run in the browser on phones, tablets and computers, with nothing to install.
Questions parents ask
Which biology game is best for younger children?
Verdant Trail starts at age 7 and begins with the parts of a plant. Sunthread Run and Windspine Citadel start at age 8 and spend more time on the human body: digestion and teeth, then bones, muscles and breathing.
What pictures do the games use?
Labelled pictures based on real scientific illustrations of plants, cells and the human body. In a picture level, children tap the part that is named; some picture levels first let them explore the picture with every label shown.
Are the biology games free?
Levels 1 and 2 of every biology game are free without an account, and levels 3 and 4 are free with an account. From level 5 on, levels are part of the subscription.
What does my child do in a level?
Each level uses one kind of challenge: finding parts on a picture, sorting cards into groups, putting steps in order, matching pairs, filling gaps in sentences or choosing the right answer. Right answers wear down the level's guardian.
