• Weather is the short-term state of the atmosphere at a place and time, such as today's temperature, rainfall, and wind.
• Climate is the long-term pattern of weather in a place, identified using data collected over decades.
• Weather can change hour-to-hour and day-to-day, but climate describes average conditions and typical seasonal patterns over many years.
• The main elements of weather are temperature, precipitation (rain, snow, or hail), wind, humidity, and atmospheric pressure.
• Air temperature is typically measured using a thermometer, usually in degrees Celsius.
• Rainfall is measured using a rain gauge, usually in millimetres.
• Wind speed is measured using an anemometer, and wind direction is shown by the direction from which the wind is blowing, often measured using a wind vane.
• Humidity is the amount of water vapour in the air, and it affects how dry or sticky the air feels and how likely cloud and rain are.
• Atmospheric pressure is the force of the air pressing down on the Earth's surface and is commonly measured in millibars or hectopascals.
• Tropical climates are hot throughout the year, but their rainfall may be year-round, seasonal, or low; polar climates are very cold; arid climates are very dry and can occur at different latitudes; and temperate climates have moderate temperatures and clear seasons.
• Latitude affects climate because it changes the angle and intensity of sunlight, which influences average temperatures.
• Altitude affects climate because temperature generally decreases with height above sea level, often making high areas cooler than nearby lowlands.
• Distance from the sea affects climate because oceans moderate temperatures, producing cooler summers and milder winters, and can increase moisture and rainfall.
• Ocean currents and prevailing winds transport heat and moisture, influencing the climate of coastal and inland areas.
• Weather maps use standard symbols to show features such as wind direction and speed, precipitation, temperature, and pressure patterns.
• Air moves from areas of higher atmospheric pressure towards areas of lower atmospheric pressure.
• In low-pressure systems, rising air cools, which may cause water vapour to condense and form cloud and precipitation.
• In high-pressure systems, sinking air tends to produce drier, more settled conditions.
• Weather fronts (cold, warm, and occluded) mark boundaries between air masses and often bring changes in cloud, temperature, and precipitation.
• Forecasts use observations and modern tools such as satellites, radar, and computer models, and forecast accuracy generally decreases the further ahead the prediction is made.
• Microclimates are small-scale variations in climate within short distances.
• Buildings, vegetation, and topography influence microclimates.
• Urban areas often create heat islands with higher temperatures.
• Primary weather data can be collected using thermometers, rain gauges, and anemometers.
• Consistent recording of primary weather data is essential for recognising patterns.
• Graphs and charts make trends in weather data easier to interpret.
• Microclimate variations can impact human activity, such as the use of playgrounds and gardens, and building design.
• Understanding local weather patterns helps communities plan daily activities safely.
• Climate knowledge informs agriculture, infrastructure, and disaster preparedness.

• Compare weather and climate by describing at least two differences, including how data is collected (short-term observations versus decades of records).
• Measure local weather elements using appropriate instruments (for example, a thermometer, rain gauge, and anemometer) and record readings with correct units.
• Collect primary weather data using consistent methods (the same location, time intervals, and equipment) to improve reliability and allow fair comparison.
• Present weather data in tables and appropriate graphs (for example, line graphs for temperature over time and bar charts for rainfall) with clear labels and units.
• Identify daily patterns, trends, and anomalies in a dataset by describing what changes, when it changes, and how unusual values differ from the rest.
• Interpret a weather map by reading temperature, pressure, and precipitation symbols and linking high- and low-pressure patterns to likely weather conditions.
• Identify cold, warm, and occluded fronts on a weather map and predict the likely weather changes associated with the front passing.
• Evaluate a weather forecast by judging its reliability using lead time (how far ahead it is), agreement between sources, and comparison with observed conditions.
• Investigate microclimates by comparing measurements from contrasting sites (for example, shaded versus sunny or urban versus rural) and explaining differences using vegetation, buildings, and surface materials.
