Sports Practice Planner with Weather Rules
Combine practice times with forecast to flag cancel, indoor, or outdoor decisions based on thresholds. Students define clear rules, build a simple scheduler, and display guidance for coaches and families.
City Climate Comparison Report
Create a two city climate profile using monthly averages from a public dataset and include a written summary. Students compute means, medians, and variability, then communicate findings in a clear report layout.
School Day Weather Dashboard
Build a mobile friendly dashboard with current conditions, hourly forecast, and a recess recommendation badge. Students practice layout grids, API polling schedules, and clear iconography.
UV and Air Quality Safety Alert
Fetch UV index and AQI for the school location and display a safety status with links to sun and breathing tips. Students learn thresholds, inclusive design, and how to justify safety messages with data.
Bus Stop Nowcast with Geolocation
Use the device location to pull minute by minute precipitation forecasts for the next hour. Students work with browser geolocation, permission prompts, and graceful fallbacks when location is blocked.
Pollen Tracker for School Garden
Display pollen levels and plant types with simple charts and color coded advice for allergy sensitive students. Students integrate a specialized API and interpret categorical data for clear communication.
Extreme Weather Watchlist
Create a watchlist that highlights alerts like thunderstorms or heat advisories with icons and expiration times. Students handle nested JSON structures and learn how to present urgency without causing panic.
Three City Climate Chart Pack
Build line and bar charts for temperature, humidity, and precipitation for three selected cities. Students practice chart libraries, legends, and accessibility features like text alternatives and color contrast.
Weather Driven Soundscapes
Generate background sounds that change with precipitation or wind using Web Audio API tied to weather data. Students explore creative coding, mapping numbers to effects, and user controls for volume and timing.
Hurricane Tracker with Storm Paths
Pull active storm tracks and render polylines on a map with wind speed categories and movement. Students learn geospatial data formats and how to visualize uncertainty windows with transparency.
Fire Weather Risk Heatmap
Aggregate temperature, humidity, and wind to compute a simple risk score, then render a gradient map over a region. Students consider ethical communication and practice color scale selection for readability.
Ocean Buoy Wave Viewer
Fetch buoy station data to plot wave height and period with live updates and site selection. Students parse time series, handle missing values, and connect marine science concepts to visualization.
Earthquake and Weather Evacuation Planner
Combine recent earthquake feed with local weather to suggest safe outdoor meeting areas under different conditions. Students integrate two APIs, filter by distance, and justify recommendations with criteria.
Smart Thermostat Simulator
Simulate indoor temperature using outside conditions, time of day, and a basic energy model with a visual dial. Students design sliders for variables, build a simple physics approximation, and chart outcomes.
Renewable Output Estimator
Use sunlight and wind data to estimate daily energy output for a small solar panel or turbine model. Students code formulas, compare predicted versus actual results from classroom measurements, and iterate.
Flood Risk and Rainfall Overlay
Display recent rainfall totals with a transparent overlay on a local map and include links to community resources. Students discuss data limits, map layering, and how to present preparedness steps.
Recess Weather Scorecard
Teams build dashboards that score daily recess conditions and track streaks for best days. Students design metrics, debate fairness, and present findings to classmates for a friendly contest.
Backpack Packing Challenge
Create a daily packing list generator based on forecast, UV, and after school activity. Students map thresholds to items and practice concise UI to reduce decision fatigue in the morning.
Walk to School Comfort Index
Build an index that combines temperature, wind, and precipitation to rate walking comfort and suggest clothing. Students normalize variables, weight factors, and justify index design with evidence.
Event Day Picker for School Calendar
Create a tool that scans the next 30 days and flags high confidence good weather dates for outdoor events. Students handle probability fields where available and present a clear ranked list.
City Challenge: Optimal Solar Field Trip
Teams compare several cities using cloud cover and UV to pick the best date and place for a solar experiment. Students negotiate tradeoffs, present a pitch, and cite data sources responsibly.
Weather Trivia Bot with Live Facts
Build a chat style bot that pulls a current fact, like highest wind speed in region today, and quizzes the user. Students practice string templates, API error handling, and scoring logic.

Publish a web page that explains today air quality with a kid friendly legend and health tips. Students focus on clear communication, accessibility, and linking to local resources.
Pro Tips
- *Provide a shared list of beginner friendly APIs with sample requests and rate limits so students do not hit blockers during class.
- *Use tiered rubrics where basic credit is for pulling and displaying data, then add stretch goals like charts, alerts, and accessibility checks.
- *Model safe API key handling with proxy use or school controlled keys and rotate them regularly to protect student work.
- *Assign roles in pairs, such as data wrangler and interface designer, then switch halfway so every student practices both skills.
- *Plan offline fallbacks by stubbing a small JSON file so students can continue coding when the API is down or the network is slow.
