🌊 DepthQuest

Dive from the sunlit surface to the crushing dark of the deepest trenches. Learn how pressure, light, and temperature change with depth — and how amazing creatures are built to survive each ocean zone.

Predict, dive & practice

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

Depth Dive Pilot a submarine down the water column. Before each descent, PREDICT what happens to the pressure, light, and temperature — or read the gauges and predict which ocean zone you are in — then check. Making the prediction first is the best way to really learn. Predict · Pressure / light / zones Adaptation Match Meet a deep-sea creature and its special adaptation — huge eyes, a glowing lure, pressure-proof proteins, chemosynthesis. PREDICT which ocean zone it is built to survive in, then find out why the trait fits that depth. Predict · Deep-sea adaptations Concept Kits 16 quiz kits — 400 questions across ocean zones, marine life, currents & tides, coral reefs, the deep sea, ocean chemistry, food webs, technology, and conservation — with a hint after a first miss and an explanation every time.

Play together

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

Depth 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 duel a friend on another device. Explorer's Dive — follow the current → A path through all 16 kits. Clear each stop, then move on — see how far you've descended.

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. 🌊 DepthQuest Sprint — a calm speed round → Once you’ve mastered a few kits, race your OWN best on what you already know. Timer optional, no penalty for a miss.
