How to Use This Guide
Begin with the shared reference, then select the pathway that matches the learner. Every pathway uses the same scientific habits at a different level of complexity.
Grades K-2
Name conditions, compare days, and show patterns with words and pictures.
Grades 3-5
Measure variables, graph change, and support claims with data.
Grades 6-8
Explain interactions and make short-range evidence-based forecasts.
Grades 9-12
Analyze systems, uncertainty, model performance, and risk.
A repeatable learning cycle
- Observe: What is happening now?
- Compare: What changed across time or place?
- Explain: How might air, water, and energy produce the pattern?
- Forecast: What may happen next, where, and when?
- Verify: How well did the forecast match later observations?

Weather and the Atmosphere
Weather describes atmospheric conditions at a particular time and place. Climate describes the typical range and pattern of weather for a region over many years. A single hot, rainy, or snowy day is weather; long-term records help scientists describe climate.
The energy that drives weather
Sunlight warms Earth unevenly. Differences in heating create differences in temperature and air pressure. Air moves, water changes phase, and weather systems develop as the atmosphere redistributes energy and moisture.
| Process | What happens | Weather connection |
|---|---|---|
| Radiation | Energy travels from the Sun and Earth | Controls heating and cooling |
| Conduction | Energy moves by direct contact | The ground warms or cools nearby air |
| Convection | Warmer, less dense fluid rises; cooler fluid sinks | Builds clouds and circulations |
| Phase change | Water evaporates, condenses, freezes, or melts | Moves moisture and latent heat |
Four variables to watch first
Temperature
How hot or cold the air is. Common units: °F and °C.
Air pressure
Force from the weight of air above. Common units: hPa, mb, and inHg.
Humidity
The amount of water vapor in the air, often described with relative humidity or dew point.
Wind
Air moving from one place to another, described by speed and the direction it comes from.
Observation and inference: “Pressure fell 5 hPa” is an observation. “A low-pressure system may be approaching” is an inference. Label each clearly.
Core reference
Weather Instruments
A weather station turns conditions into measurements that can be compared. Good measurements depend on correct placement, consistent timing, and careful notes.
| Instrument | Measures | Placement and reading tip |
|---|---|---|
| Thermometer | Air temperature | Shade it from direct sun and keep it away from heat sources. |
| Barometer | Air pressure | Record at the same time; note whether pressure is rising or falling. |
| Hygrometer | Relative humidity | Allow the sensor to adjust; pair the reading with temperature. |
| Anemometer | Wind speed | Use an open location away from walls and trees. |
| Wind vane | Wind direction | Align north correctly and avoid obstructions. |
| Rain gauge | Liquid precipitation depth | Place it level in the open and empty it after reading. |
Observation quality check
- Record date, time, and exact location.
- Include a unit with every number.
- Use instruments in consistent locations.
- Describe sky cover and cloud type.
- Note obstructions, malfunctions, and missing observations.
Core reference
Reading Clouds
Clouds form when air becomes saturated and water vapor condenses onto tiny particles. Shape, altitude, growth, and change offer clues about moisture, stability, and approaching weather, but no single cloud guarantees a particular outcome.
| Name clue | Meaning | Example |
|---|---|---|
| cirro | high and icy | Cirrus: thin streaks or wisps |
| alto | middle level | Altocumulus: patches of rounded cloudlets |
| stratus | layer | Stratus: a widespread sheet |
| cumulus | heap or tower | Cumulus: puffy clouds with flatter bases |
| nimbus | precipitation bearing | Nimbostratus: widespread precipitation |
Core reference
Water in the Weather System
Water continually moves between Earth’s surface and atmosphere. Evaporation and transpiration add water vapor. Rising air expands and cools; if it reaches saturation, cloud particles may form, grow, and fall as precipitation.
| Change | Direction | Energy relationship |
|---|---|---|
| Evaporation | liquid to gas | absorbs energy |
| Condensation | gas to liquid | releases energy |
| Melting | solid to liquid | absorbs energy |
| Freezing | liquid to solid | releases energy |
| Sublimation | solid to gas | absorbs energy |
| Deposition | gas to solid | releases energy |
Precipitation types
Rain
Liquid drops reach the ground.
Snow
Ice crystals or flakes avoid melting.
Sleet
Melted snow refreezes into ice pellets.
Freezing rain
Supercooled liquid freezes on contact.
Hail
Thunderstorm updrafts cycle ice through the cloud.
Dew point
A moisture measure tied less directly to current temperature than relative humidity.
Core reference
Pressure Wind and Fronts
The pressure-gradient force starts air moving from higher toward lower pressure; Earth’s rotation and friction change its path and speed. Closely spaced isobars generally indicate a stronger pressure gradient.
| Feature | Typical pattern | What to investigate |
|---|---|---|
| High pressure | Sinking and spreading air often limits cloud growth | Clearer conditions and seasonal exceptions |
| Low pressure | Converging and rising air can support clouds | Precipitation, storm track, pressure trend |
| Cold front | Advancing cold air lifts warmer air | Showers or storms, wind shift, cooling |
| Warm front | Warm air glides over retreating cool air | Layered clouds, steady precipitation, warming |
| Stationary front | Boundary moves little | Persistent clouds or precipitation |
| Occluded front | A cold front overtakes a warm front | A mature low and widespread weather |
Do not overread one map. Forecasts also use upper-air observations, radar, satellites, numerical models, local terrain, and knowledge of uncertainty.
Core reference
Storms and Hazardous Weather
A watch generally means hazardous weather is possible and it is time to prepare. A warning means the hazard is occurring or imminent and protective action is needed. Always follow the exact instructions in official alerts.
| Hazard | Science clue | Primary concern |
|---|---|---|
| Thunderstorm | Moisture, instability, and lift support deep convection | Lightning, hail, damaging wind, heavy rain |
| Tornado | A rotating column of air reaches the ground | Extreme wind and flying debris |
| Flood | Water accumulates faster than it can drain | Fast water, hidden damage, contamination |
| Tropical cyclone | Organized warm-ocean storm with closed circulation | Storm surge, wind, rain, tornadoes |
| Winter storm | Cold air and moisture combine | Travel, exposure, snow, and ice |
| Heat | Heat gain exceeds the body’s ability to cool | Heat illness and dehydration |
Safety first
Weather Safety Decision Guide
Observation never outranks safety. Know where to go before conditions deteriorate, keep more than one way to receive alerts, and follow local emergency plans.
| If this happens | Do this |
|---|---|
| You hear thunder | Go immediately into a substantial building or hard-topped vehicle. Wait at least 30 minutes after the last thunder before resuming outdoor activity. |
| A tornado warning is issued | Go to a basement or small interior room on the lowest floor, away from windows. Protect your head and neck. |
| Water covers a road or path | Do not enter on foot or in a vehicle. Turn around and use another route. |
| Extreme heat is expected | Limit strenuous activity, seek cooling, drink water, and check people at greater risk. Never leave anyone in a parked vehicle. |
| Winter weather threatens | Avoid unnecessary travel, dress in layers, stay dry, and prepare for disruptions. |
| A hurricane or coastal flood threatens | Follow evacuation orders and local guidance; account for surge, wind, rain, and tornadoes. |
Before fieldwork
- Check the official forecast and alerts.
- Name the nearest safe indoor location.
- Set a stop rule for heat, cold, wind, thunder, or visibility.
- Bring needed clothing, water, and communication tools.
- Use remote or archived data when conditions are unsafe.
Core reference
Forecasting with Evidence
A forecast is a testable statement about future conditions at a defined place and time. Strong forecasts combine observations, patterns, models, and uncertainty, then change when new evidence arrives.
Place
School campus and surrounding neighborhood
Time
Tomorrow from 7 a.m. to noon
Conditions
Cloudy, 55-60°F, light southwest wind, rain possible
Confidence and evidence
Medium confidence because models agree on clouds but differ on rain timing
Forecast tools
| Tool | Best use | Limit |
|---|---|---|
| Surface observations | What is happening now | Sparse between stations |
| Radar | Location and motion of precipitation | Does not show every hazard |
| Satellite | Clouds, moisture, and storm structure | Interpretation depends on sensor and wavelength |
| Computer model | Possible future atmospheric states | An approximation with uncertain inputs and physics |
| Ensemble | Range and likelihood of outcomes | Requires careful probability interpretation |

- Archive at least 10 forecasts with issue time, valid time, and lead time.
- Collect matching observations from one consistent station.
- For continuous data, calculate forecast error, mean error, and mean absolute error. For yes-or-no precipitation, classify hits, misses, false alarms, and correct negatives.
- Graph performance by lead time or weather regime and explain limitations.
Error
Forecast minus observation. The sign shows whether the forecast was high or low.
Mean error
Average signed error. It summarizes bias, but positive and negative errors may cancel.
Mean absolute error
Average size of errors without regard to sign.
