Using Weather Instruments

Use weather instruments to measure and record weather data: thermometers for temperature in °C, rain gauges for rainfall, wind vanes for direction, and anemometers for wind speed — and keep a weather diary over time

Quick check

If the learner had a thermometer, rain gauge, and wind vane at school, could they take daily readings, record them in a table, and spot patterns over a week or month?

What a learner can do once this topic is secure.
  • Name at least three weather instruments and explain what each measures
  • Read a thermometer and record the temperature in degrees Celsius

Teaching notes

From the Marble Skill Taxonomy. These notes have not been validated in classrooms, so treat them as a starting point for your own judgement.

The approach

Children aged 7–9 learn the procedure of measuring and recording weather: reading a thermometer (°C), a rain gauge (mm), a wind vane (direction) and an anemometer (speed), keeping a weather diary over at least a week, and turning the recorded table into a bar graph/pictograph so a pattern emerges. The core objective is a hands-on measure-and-record skill performed over time, with accurate scale-reading and consistent (same place, same time) measurement, culminating in the move from raw readings to a data representation.

Common misconceptions

  • A wind vane measures wind SPEED — it shows DIRECTION; the anemometer measures speed
  • The rain gauge shows total rain ever — it is read then emptied for each period
  • Reading a thermometer from an angle gives the true value — must read at eye level
  • Any single reading describes the weather — patterns need repeated, consistent measurements over time
  • Bigger numbers are always 'more weather' — units and what is measured matter (mm of rain vs °C)

Useful representations

  • An instrument panel pairing each tool with its quantity and unit
  • A weekly weather-diary table filling in day by day
  • A bar graph/pictograph built from the recorded data
  • A close-up scale (thermometer, rain gauge) for practising accurate reading

Teaching practices

  • Match instrument → quantity → unit explicitly (thermometer/°C, rain gauge/mm, wind vane/direction, anemometer/speed)
  • Teach accurate scale-reading, especially eye-level thermometer reading and zeroing the rain gauge
  • Keep a real weather diary over at least a week so raw readings become a data table
  • Turn the table into a bar graph/pictograph (per 3-ESS2-1) so children see the pattern the numbers hide
  • Stress fair, consistent measurement — same location, same time of day — to make comparisons valid

Activities to try

  1. 1

    Weather-station logbook: read, record, graph

    Why it works: A single reading is real data, but it only shows one moment; a week of consistent, correctly-unit-ed readings becomes a data story, and a graph makes the pattern leap out of numbers that looked scattered — the step from measurement to representation.

    1. Each 'day', read the thermometer to the nearest °C with your eye level with the top of the liquid, read the rain gauge in mm on a flat surface at the meniscus, note the direction the wind vane arrow points, and read the anemometer for wind speed (for example in km/h, or as spins counted in a set time on a homemade anemometer).
    2. Write each reading into a weather-diary table with its date and unit (e.g. 12°C, 4 mm, wind from the west, wind speed 10 km/h or 15 spins in 30 seconds).
    3. Repeat the routine for at least a week, keeping the place and time of day the same each day.
    4. After a week, turn the table into a bar graph or pictograph with equal, labelled axis intervals, then read the pattern aloud (e.g. 'a run of cold wet days, then a warm dry spell').
    5. Say why scientists measure consistently over time rather than relying on a single reading.
  2. 2

    Match each instrument to its quantity and unit

    Why it works: Each instrument measures a specific quantity in a specific unit; knowing the pairing is the foundation for choosing the right tool and reading it correctly.

    1. Pair each instrument with the quantity it measures and the unit used: thermometer → temperature → °C; rain gauge → rainfall → mm; wind vane → wind direction; anemometer → wind speed.
    2. Explain in your own words why a wind vane does NOT measure speed and why the anemometer does.
    3. Given a number with a unit (e.g. 15 mm, 15°C), say what was measured and why the unit matters — a bigger number is not simply 'more weather'.
  3. 3

    Check the skill: read a scale and interpret a graph

    Why it works: A correct reading plus a correct interpretation of the graph shows the procedure has been learned, not just recognised.

    1. Read a shown thermometer to the nearest °C, placing your eye level with the top of the liquid.
    2. Given a completed weekly bar graph, answer questions about the pattern (e.g. which day was warmest, whether the week was mostly wet or dry, what the weather was usually like that week, and why more weeks of data would be needed to describe a whole season).
    3. Spot and fix a problem reading: a tilted rain gauge, a wind direction reported backwards, or a graph with unlabelled axes.
