🎒 Ages 9–14 · Grades 4–8
HarvestForge
Ages 10–13 · Gr 5–8 Level 3
Run a farm from seed to shelf — predict how a crop will do before you plant it in the Crop-Rotation Lab, trace a loaf of bread back through every pair of hands that grew and carried it in the Supply-Chain Trace, and learn the science of soil, water, food systems, and food justice across 16 kits. The animated farm and real-weather sim stay in the app; here you build the knowledge.

WeatherForge
Ages 9–11 · Gr 4–6 Level 2
Step into the weather lab: read a synoptic panel of pressure, humidity, and fronts to forecast tomorrow, give a percent-chance of rain and see how well-calibrated your confidence is, assemble the conditions that spawn a hurricane or tornado, and learn what every weather instrument measures — then practice meteorology across 16 kits. On-device; works with the sound off.

ClimateQuest
Ages 10–13 · Gr 5–8 Level 3
Slide the CO₂ level and watch a real (simplified) climate model respond — greenhouse forcing, warming, sea level, and sea ice. Predict the warming before the model reveals it, read climate datasets, build the four feedback loops that drive Earth's climate, and practice the carbon cycle, greenhouse effect, ocean systems, and climate solutions across 16 kits. Hope-forward and on-device; works with the sound off.

StarForge
Ages 9–12 · Gr 4–7 Level 3
Pilot the solar system: tap a planet on the orbit map for real NASA data, take a mission challenge, predict a moon phase before the reveal, and practice astronomy across 16 kits.
Play StarForge →
CosmosForge
Ages 11–13 · Gr 6–8 Level 4
Watch a star live and die in the Stellar Evolution lab, peer inside a black hole and feel gravity stretch time, climb the Cosmic Distance Ladder, and practice astronomy & astrophysics across 16 kits.

HorizonQuest
Ages 10–13 · Gr 5–8 Level 3
The real-sky companion that gets the family OUTSIDE: see tonight’s real Moon phase, pick your part of the world on a map, and learn the naked-eye stars, planets, and asterisms to look for — with five little sky guides. On-device — no location, no camera, no account, no AI.

RiverForge
Ages 9–13 · Gr 4–8 Level 3
When it rains on a hillside, where does the water actually go? Not wherever it likes — it obeys one rule: roll to the lowest neighbour, over and over, until you reach a low spot and pool. Trace that and you can find every pond, see the ridge that splits the rain into two rivers, spot the square that floods first, and watch what a levee really does to the water downstream. Predict the flow, then drop your own raindrops on the valley map. Real, tiny, deterministic earth science — no internet. Ages 9–14.
