WonderLab: free elementary science across space, animals, and more
WonderLab is a friendly tour of elementary science and nature. Kids explore eight big topics — space, animals, the human body, weather, plants, physics, rocks, and food webs — by quizzing, sorting, and putting things in order. It's free, with no ads and no tracking of your kids.

What kids learn
- Space: the planets and their order, day and night, moon phases, and seasons
- Animals: vertebrates and invertebrates, animal groups, and life cycles
- The human body: the heart, lungs, brain, organ systems, and digestion
- Plants and ecology: parts of a plant, photosynthesis, and food-chain roles
- Physical science: states of matter, floating and sinking, and pushes and pulls
- Earth science: the rock cycle, clouds, the water cycle, and storm safety
How it works
From a topic menu, kids pick a set and play one of three ways: a quiz, a Classify It sorting round, or a Put It In Order sequence. Every answer gets instant green-or-coral feedback and auto-advances. Each set scores correct answers for up to 3 stars.
A grown-up signs in once and adds a player for each kid, so WonderLab's stars and progress save to your account and follow you to any device.
