Reading weather data

Weather and climate

CCSS NGSS.3-ESS2-1England: KS2 Y3–Y4 Working scientifically

Objective and success criteria

Students will: Reading weather data.

  • I can answer questions on today's skill on my own, without help.
  • I can explain each step and say why it works.
  • I can check my answer and spot a mistake.

Before and after

Needs first: Measuring the weather

Leads to: Weather and climate zones; Temperature charts: warmest, coldest and range; Compare rainfall month by month

Materials: Weather maps, Thermometers, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).

Warm-up · 5 min

  • Quick retrieval from earlier learning (Measuring the weather). Students answer on mini whiteboards.
  • Show answers together and note who needs support in the main task.
  1. Which instrument would you use to measure wind speed? (rain gauge / anemometer / wind vane / barometer) → anemometerPrompt: Is it about rain, temperature, wind speed, wind direction or pressure?
  2. What does an anemometer measure? (air pressure / whether pressure is rising or falling / the temperature in °C / how fast the wind is blowing) → how fast the wind is blowingPrompt: Think about what each instrument looks like and does.
  3. Which instrument would you use to measure how fast the wind is blowing? (thermometer / anemometer / rain gauge / barometer) → anemometerPrompt: Is it about rain, temperature, wind speed, wind direction or pressure?

Hook · 5 min

  • Show today's forecast and ask what it means for the class and how forecasters know.
  • Share the objective: Reading weather data. Read the success criteria together.

I do: model it · 10 min

  • Work through the example out loud, saying why you do each step, not just what you do.
  • Example: Temperatures (°C) on five days were 20, 13, 11, 17, 11. What was the mean temperature? Give 1 decimal place.
  • Step 1: (20 + 13 + 11 + 17 + 11) ÷ 5 = 14.4
  • Step 2: So the answer is: 14.4 °C
  • Answer: 14.4 °C
  • Pause after each step and ask a student to say what comes next.

We do: guided practice · 10 min

  • Do these together. Students try each step on whiteboards before you reveal it.
  • Use the hints as prompts rather than giving the answer.
  1. Temperatures (°C) on five days were 9, 7, 10, 13, 14. What was the mean temperature? Give 1 decimal place. → 10.6 °CPrompt: Add the temperatures.
  2. Temperatures (°C) on five days were 16, 23, 22, 22, 23. What was the mean temperature? Give 1 decimal place. → 21.2 °CPrompt: Add the temperatures.

You do: independent practice · 10 min

  • Students work on the student sheet. Circulate and check the first two answers of every student early.
  • Students who finish: write a question of their own for a partner, with the answer.

The 8 questions are on the student sheet below, with answers in the key.

Exit ticket · 5 min

  • Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
  1. Temperatures (°C) on five days were 15, 13, 12, 18, 21. What was the mean temperature? Give 1 decimal place. → 15.8 °CPrompt: Add the temperatures.
  2. Temperatures (°C) on five days were 17, 20, 18, 14, 23. What was the mean temperature? Give 1 decimal place. → 18.4 °CPrompt: Add the temperatures.

Watch out for

  • Everyday meanings of words getting in the way of the science meaning: define key words explicitly.
  • Remembering facts without the reason: ask "why?" and "what is the evidence?"

Support and stretch

Support

  • Review first: Measuring the weather.
  • Use concrete materials: weather maps.
  • Give the first step of each question, or a partly worked example to finish.
  • Pair with a confident partner for the guided practice.

Stretch

  • Move on to: Weather and climate zones; Temperature charts: warmest, coldest and range; Compare rainfall month by month.
  • Explain a common mistake in writing and how to fix it.
  • Write a word problem that uses today's skill, then solve a partner's.
