A voxel city-builder where kids settle an island with an active volcano β and learn earth-science and computational thinking by deciding where and how to build when they know the mountain will erupt.
Students choose an island, grow a village into a city, and protect it from natural disasters that strike on a semi-predictable schedule. The "stealth" curriculum: how volcanoes and hazards work, why people settle dangerous places (rich volcanic soil!), and how to weigh cost against benefit when making a plan. Here is every tool a child actually uses.
Kids pick from five islands with different terrain, hazards, and difficulty: Green Valley (beginner, calm), Mount Ember (frequent eruptions but super-fertile ash), Windward Reef (low & wide β tsunamis & hurricanes), Rift Isles (earthquake-prone, cracked land), and Great Highlands (biggest island, lots of room). Each choice changes the science problem to solve.
The game runs on two things kids must balance. Food (π) is grown by farms and eaten by villagers β a small village feeds everyone free, but a big town must keep planting to grow more than it eats. Materials (π§±) are spent to build and repair; disaster report cards deliver recovery materials. Every build shows its material cost, so kids constantly manage a budget.
Houses add population; farms grow food. A farm planted on dark volcanic ash grows double food. Buildings kept safe long enough grow bigger on their own β houses hold more people, farms yield more β a reward for protecting them.
Rings its bell before a disaster and automatically evacuates every villager inside its yellow ring. Teaches early-warning systems.
Keeps the shore inside its blue ring dry during a tsunami. Small / Seawall / Great cost more materials and protect a wider area β a direct size-vs-cost trade-off.
Buildings in the Guild's orange ring are quake-proof. After an earthquake, the REPAIR button fixes cracked buildings for a little material β modeling building codes and recovery.
Blocks flowing lava so it slides around the wall's zone β just like real barriers engineers build in Iceland and HawaiΚ»i. Bigger walls block a wider area.
Tap Remove, then tap any building you placed to take it down and get half its materials back. Lets kids rearrange freely and revise a plan β no decision is permanent.
Appears when danger is high and changes with the hazard: "to the beach" for a volcano, "run UPHILL" for a tsunami, "go INSIDE" for a hurricane. The right response depends on the disaster.
From the menu, kids flip the island into a map: Risk Map highlights predicted lava, past lava paths, flood zones, and high ground; Elevation Map shades the land by height. They read these maps to plan where it's safe to build.
An objective chip nudges the next step; a live Danger Meter names the threat and shows warning signs so kids predict and act early. After each disaster a report card gives stars for safety, protection (buildings saved), and preparedness (early action / warning coverage), then asks: "what will you change before the next disaster?"
Dr. Rocky, the island scientist, drops real geology facts as you play, and the menu's Field Guide collects hazard tips, the toolbox, and a running list of "things you've learned."
The game spans grades 2β4, so it touches both CSTA Level 1A (Kβ2) and Level 1B (3β5). Standard text below is quoted verbatim from the CSTA Kβ12 Computer Science Standards (2017) and the Next Generation Science Standards.
| Code | Standard (verbatim) | How Volcano Island addresses it |
|---|---|---|
| Level 1A Β· Grades Kβ2 | ||
| 1A-AP-08 | "Model daily processes by creating and following algorithms (sets of step-by-step instructions) to complete tasks." | Evacuation is a step-by-step procedure kids follow: watch the meter β tap EVACUATE β villagers run the correct route. Building a village is also a repeated sequence of actions. |
| 1A-AP-11 | "Decompose (break down) the steps needed to solve a problem into a precise sequence of instructions." | "Keep my village safe" breaks into ordered steps β plant a farm for food, add houses, add a tower or wall, then evacuate on the warning. The Objective chip scaffolds this sequence. |
| 1A-DA-07 | "Identify and describe patterns in data visualizations, such as charts or graphs, to make predictions." | The Danger Meter and the Risk Map are live data displays; kids read the rising bar, warning signs, and predicted-lava zones to predict what will happen and act before it does. |
| Level 1B Β· Grades 3β5 | ||
| 1B-AP-08 | "Compare and refine multiple algorithms for the same task and determine which is the most appropriate." | To stay safe, kids compare strategies β a Tower (auto-evacuate) vs. tapping EVACUATE by hand vs. a Seawall vs. a Lava Wall β pick the most appropriate for the threat and budget, and refine each round using the report card's reflection prompt. |
| 1B-AP-11 | "Decompose (break down) problems into smaller, manageable subproblems to facilitate the program development process." | A thriving city is many subproblems β food supply, materials budget, housing, tsunami defense, lava diversion, quake-proofing β each solved with a different, dedicated tool. |
| 1B-DA-07 | "Use data to highlight or propose cause-and-effect relationships, predict outcomes, or communicate an idea." | The loop is cause-and-effect from data: farms on ash yield double (+π shown), the Food-per-day rate warns of famine, the Risk Map's past-vs-predicted lava shows where flows go. Report-card data guides the next plan. |
| Code | Performance Expectation (verbatim) | How Volcano Island addresses it |
|---|---|---|
| 2-ESS1-1 | "Use information from several sources to provide evidence that Earth events can occur quickly or slowly." | An eruption happens in seconds; fertile ash soil and brand-new delta land build up slowly over many eruptions. Kids witness both timescales. |
| 4-ESS2-2 | "Analyze and interpret data from maps to describe patterns of Earth's features." | The Elevation Map and Risk Map are literal maps of the island's features β height, high ground, flood zones, and where lava has flowed and is predicted to flow. Kids read them to describe patterns and plan. |
| 3-ESS3-1 | "Make a claim about the merit of a design solution that reduces the impacts of a weather-related hazard." | Seawalls reduce tsunami flooding and towers give early warning; the report card lets kids judge whether their solution's merit was worth its material cost. |
| 4-ESS3-2 | "Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans." | Players generate and compare defenses β seawall vs. lava wall vs. tower vs. guild, and where to build β to protect people from lava, waves, wind, and quakes. |
| 3-5-ETS1-1 | "Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost." | Protecting the village with a limited materials budget before the next eruption is a design problem with clear success criteria and a real material constraint. |
| 3-5-ETS1-2 | "Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem." | The three seawall and lava-wall sizes make this concrete: kids weigh area protected against material cost to choose the solution that best fits the threat and their budget. |

Three short lessons that span the grade band. Each names the exact in-game tools students use. Tip: use the β° menu's Teacher / Scenario Controls to trigger the hazard on cue, and Pause to discuss.
Quick prompts for talking with a child about the island they made.
Capstone task β "Design & Defend Your Own Island": a student picks an island (or sketches one on paper), plays through at least one disaster, and then explains their plan β what they built, why, and what they'd change. Use this simple 3-level rubric.
| Skill | π± Getting Started | ποΈ Town Planner | ποΈ Master Planner |
|---|---|---|---|
| Reads maps & warnings to plan | Reacts only after a disaster hits. | Uses the Danger Meter and evacuates in time on most rounds. | Uses the Risk/Elevation Map to build in safe spots and predicts the hazard early every time. |
| Manages food & materials | Spends without a plan; runs out of food or materials. | Keeps farms feeding the town and usually affords key buildings. | Balances food (mouths to feed) and materials (to build); spends on what matters and explains the trade-off. |
| Matches the tool to the hazard | Builds without linking a tool to a threat. | Uses at least one right defense (e.g., a seawall for waves). | Chooses and places the best defense for each hazard and compares options (sizes, tower vs. wall). |
| Explains cause & effect ("why") | Describes what they built. | Gives a reason ("ash grows more food"). | Uses evidence from the game (harvest numbers, the lava path, the report card) to explain choices and predict next time. |
Extension: have students present their island to the class and defend one decision using data from the report card or the Risk Map.
