|---|---|---|---|
| Flowering plants | Garden Grow Team | 3 (or 2) players | Water / Light / Nutrients (one dial each) |
| Sounds | Orchestra Cooperation | 3 (or 2) musicians | Drums / Guitar / Keyboard volume |
| Matter | Matter Transformation Team | 3 (or 2) partners | Heat / Cool / Container size |
| Water cycle | Water Cycle Watch Team | 3 (or 2) meteorologists | Thermometer / Hygrometer / Anemometer (secret) |
Use the on-screen player-count buttons to switch between 3 and 2 players. In 2-player mode the game auto-provides the third factor so pairs can still win.
Learning objectives:
How it works. The student cares for one plant through 6 stages — seed → germination → seedling → flowering → fruit & seeds → cycle repeats. They give the right care (water + warmth, the correct amount of water, light + air, pollination, seed release). The plant visibly grows on screen.
Science & answer key. A seed needs water and warmth to germinate; a seedling needs light and air (CO₂) to make its own food by photosynthesis; a flower must be pollinated (by bees/wind) before seeds form; seeds are dispersed by wind, animals or water.
Win condition. Reaching the final "release seeds / new plant" stage.
Class tip. Pause between stages to ask, "Why does it need this?" before the student acts.
How it works. Drag or tap the 6 shuffled stages into the correct order, then match each stage to its description in later rounds.
Answer key (the correct order). Seed → Germination → Seedling → Flowering → Fruit & Seeds → New plant (which begins the cycle again).
Win condition. Correctly order and match all 4 rounds.
Why the team is essential. Each gardener controls only ONE dial (water / light / nutrients). The plant grows only when all three rest in the healthy green zone at the same time. No single player can do it alone — they must talk, assign roles and agree on a shared care plan.
Science & answer key. At each stage the required water/light/nutrients differ (e.g. a seedling needs more light; fruit needs steady but not excessive water). The green zone shows the correct range.
Win condition. Balance all dials across all 5 stages to reach the fruit & seeds stage within the care turns.
Learning objectives:
How it works. A 4-mission lab with a live oscilloscope and real tones. Play instruments to discover vibration → sounds; tune string length/tension to match pitch; test sound through solid/liquid/gas/vacuum; raise amplitude for loudness.
Answer key. (Mission 2) Shorter or tighter string = higher pitch; longer or looser = lower. (Mission 3) Sound travels fastest in solids, then liquids, then gases, and not at all in a vacuum.
Win condition. Complete all 4 missions.
How it works. Sort clues into the right box across 4 rounds: high vs low pitch, loud vs quiet, and "sound travels fastest in solid / through gas / no sound".
Answer key. High pitch = fast vibration (shrill whistle, thin string); low pitch = slow vibration (drum boom, long loose string). Loud = big vibration; quiet = small vibration. No sound = vacuum only.
Win condition. Correctly sort all 4 rounds.
Why the team is essential. Each musician changes only their own volume. The band's total loudness must hit a target, so they must negotiate who plays how loud. In the finale, each player secretly holds one note (C / E / G) and must share it and tune together to make the chord ring.
Answer key. The total loudness must add to the target (and everyone contributes at least the minimum). The chord is a rising C–E–G.
Win condition. Hit the volume targets and land the chord to get "ENCORE!"
Learning objectives:
How it works. Heat or cool a substance and watch the particles change between solid/liquid/gas. Predict the state at a target temperature, then test. Discover the melting and boiling points.
Answer key. Below 0 °C solid; 0 °C = melting/freezing point; 0–100 °C liquid; 100 °C = boiling point; above ~100 °C gas.
Win condition. Complete all 5 experiments.
How it works. Sort property clues into Solid/Liquid/Gas, fixed-volume vs no-fixed-shape, compressible vs incompressible, and the exact names of changes of state.
Answer key. Solid: fixed shape, packed particles. Liquid: takes container shape, particles slide. Gas: fills container, far-apart fast particles. Bigger particle gaps = easier to compress. Names: evaporate/boil (→gas), condense (→liquid), freeze (→solid), melt (→liquid).
Win condition. Correctly sort all 4 rounds.
Why the team is essential. Each partner controls one dial (heat / cool / container). The target state is reached only when all three combine correctly, so the team must coordinate heating, cooling and the room size while watching the particles.
Answer key. Solid needs low temp + small room; liquid needs middle temp + medium room; gas needs high temp + large room; melting point needs ~0 °C.
Win condition. Reach all 4 rounds together.
Learning objectives:
How it works. The student is a water drop and picks the correct process at each of 6 stages, with an animated scene.
Answer key. Ocean → evaporate → condense into a cloud → precipitate (rain) → runoff/collection → transpiration through a plant → back to the ocean (cycle repeats).
Win condition. Complete all 6 stages.
How it works. Order the 6 stages, then match each process to its description.
Answer key. Evaporation → Transpiration → Condensation → Precipitation → Runoff → Collection (then repeat).
Win condition. Correctly order and match all 4 rounds.
Why the team is essential. Each meteorologist sees only one secret instrument reading (thermometer / hygrometer / anemometer). The forecast button stays locked until every reading is revealed and shared, so the team must pool all three conditions to predict evaporation, clouds, rain or collection.
Answer key. Mission 1: hot + dry = strong evaporation. Mission 2: warm + very humid = clouds (condensation). Mission 3: warm + very humid + strong wind = rain. Mission 4: warm + humid = runoff/collection and the cycle repeats.
Win condition. The team correctly forecasts all 4 missions.
