Science Thread

Learn science by playing. Science Thread is a free, Duolingo-style game built around discovery and wonder. Every explorer starts in the Method Lab — observation, questions, hypotheses, fair tests, data, and honest conclusions — then roams freely through the Science District.

The worlds

Scientific Methods (the Method Lab), Biology (the Living Gardens), Zoology (the Wild Reserve), Chemistry (the Elemental Workshop), Physics (the Frontier Station), Astronomy (the Observatory), Earth & Weather, the Human Body Clinic, the Ocean Deep, the Invention Workshop, the Microbe Lab, the Dinosaur Dig, and the Energy Plant.

Short, juicy 2–4 minute lessons with instant feedback. Boss battles. Hearts, streaks, levels and badges. Chat with AI recreations of great discoverers — Galileo, Newton, Curie, Mendel, Carver and more. Earn Spark Tokens ⚡ with your lab-rat guide, Discover. Works offline and installs to your home screen.
