Measuring Weather
Using simple tools to measure and record basic weather conditions like temperature and rainfall.
About This Topic
Measuring weather introduces Year 1 students to simple tools like thermometers and rain gauges for recording temperature and rainfall. They observe daily conditions, compare measurements across seasons, and design basic weather charts. This aligns with KS1 standards on seasonal changes, helping children notice patterns in spring weather, such as rising temperatures or variable rain.
In the Seasonal Changes unit, this topic builds foundational skills in observation, data collection, and simple comparison. Students explain how a thermometer's liquid rises with warmth, use gauges to quantify rain, and create charts with symbols or numbers. These practices foster scientific enquiry and introduce basic graphing, preparing for later data handling in maths and science.
Active learning suits this topic well. When children handle tools outdoors, take turns reading measurements, and update class charts together, they connect abstract numbers to real sensations like wet clothes or chilly air. Group discussions about variations reinforce accuracy and excitement for ongoing observations.
Key Questions
- Explain how a thermometer helps us measure temperature.
- Compare the rainfall in different seasons using simple measurements.
- Design a simple weather chart to record daily observations.
Learning Objectives
- Explain how a thermometer measures temperature by observing the expansion of liquid.
- Compare the amount of rainfall recorded over a week using a rain gauge.
- Design a simple weather chart to record daily temperature and rainfall observations using symbols or numbers.
- Identify different types of weather symbols used on a weather chart.
Before You Start
Why: Students need to be able to make careful observations and describe what they see to record weather accurately.
Why: Students must be able to count and recognize numbers to read measurements from tools and record data.
Key Vocabulary
| Thermometer | A tool used to measure how hot or cold something is. It usually has a liquid that rises or falls with temperature changes. |
| Temperature | How hot or cold the air is. We measure temperature in degrees Celsius (°C). |
| Rain gauge | A tool used to collect and measure the amount of rain that has fallen over a specific period. |
| Rainfall | The amount of rain that has fallen in a particular place. We measure it in millimeters (mm). |
Watch Out for These Misconceptions
Common MisconceptionThermometers measure 'cold' by the liquid going down.
What to Teach Instead
Temperature measures average kinetic energy of particles; liquid contracts in cooler conditions. Hands-on trials with ice water and warm hands let students see and feel changes, building correct cause-effect links through prediction and group verification.
Common MisconceptionRainfall amounts are the same every day.
What to Teach Instead
Rain varies by season and weather fronts. Tracking daily measurements in small groups reveals patterns, like more spring showers, and peer sharing corrects assumptions with class data evidence.
Common MisconceptionWeather charts need perfect drawings to be useful.
What to Teach Instead
Charts record data, not art. Pairs practising simple symbols and numbers focus on accuracy; teacher modelling and rotation reviews emphasise function over aesthetics.
Active Learning Ideas
See all activitiesWhole Class: Daily Weather Rounds
Gather outdoors each morning. Pass a thermometer around for children to read and call out temperature. Use a shared rain gauge to measure overnight rainfall, then record both on a large class chart with symbols and numbers. Discuss changes from previous days.
Small Groups: DIY Rain Gauges
Provide plastic bottles, rulers, and markers. Children cut tops, add stones for stability, and calibrate with water lines. Place gauges outside overnight, measure next day, and compare group results on a shared board.
Pairs: Weather Chart Design
Pairs draw weekly charts with columns for date, temperature, and rainfall. Use stickers or colours for data entry based on measurements. Swap charts mid-week to predict trends and verify with real data.
Individual: Home Weather Logs
Send home simple log sheets. Children measure backyard temperature and rain daily using provided tools, then share one entry in class circle time. Compile into a class display for seasonal comparison.
Real-World Connections
- Weather forecasters at the Met Office use thermometers and rain gauges daily to record current conditions and predict upcoming weather patterns for the public.
- Farmers use temperature and rainfall data to decide the best times for planting crops and to monitor if their fields are receiving enough water.
- Construction workers check the temperature and rainfall before starting outdoor tasks, as extreme weather can make work unsafe or impossible.
Assessment Ideas
Show students a picture of a thermometer. Ask: 'What does this tool measure?' and 'What happens to the red line when it gets warmer?'
Give each student a small card. Ask them to draw a symbol for a sunny day and a symbol for rainy weather, and write the temperature they think it is for each.
After a week of recording, ask the class: 'Did we have more or less rain this week compared to last week?' and 'What was the hottest temperature we recorded?'

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
RubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
