🔬 LabSmith

Be the scientist: make a prediction, run the experiment, and find out why. Real physics you can reason about — motion, pendulums, and circuits — plus a big bank of science questions.

Level 1

Mixed practice

Mixed practice — revisit what you've learned A short round that shuffles questions from the kits you've played, brought back when they're ready to review. Great for making it stick.

Play together

Go head-to-head with a friend — same device or an online room.

LabSmith Duel (pass-and-play) 2–4 players take turns on one device — same questions, highest first-try score wins. Or open an online room to play a friend on another device. LabSmith Journey — follow the map → A path through every kit. Clear each stop, then move on — see how far you’ve come.

Predict, run & explain

Three hands-on labs where you make a prediction BEFORE the experiment runs — the single best way to really learn — plus the concept quiz. Everything runs on your device; nothing is sent anywhere.

Projectile Lab Two launches leave at different angles and speeds. PREDICT which one lands farther before the arcs are drawn — then watch the model draw both. Learn why 45° flies farthest and why 30° and 60° tie. Predict · Motion Pendulum Lab Two pendulums differ in length, weight, or swing size. PREDICT which one swings slower before the reveal. Discover that only LENGTH changes the timing — a heavier bob and a bigger swing do not. Predict · Isolate the variable Circuit Lab Two circuits wire the same bulbs in series or parallel. PREDICT which one makes each bulb glow brighter — then see the power per bulb. Learn why parallel bulbs stay bright and series bulbs dim as you add more. Predict · Electricity Concept Kits 16 quiz kits — 400 questions across forces & motion, energy, simple machines, matter, chemical reactions, light & sound, electricity & magnetism, and the scientific method — with a hint after a first miss and an explanation every time.
