Weather Climate Differences

Overview

In this lesson (Lesson 2 of 20) from “Exploring Earth and Space”, students compare weather and climate using a small set of local weather data. They will identify patterns and potential anomalies, then justify a claim using evidence.

Learning intentions

Students will:

• describe the difference between weather and climate
• analyse local weather data to identify patterns and trends
• identify anomalies (unexpected values) in a data set and suggest plausible reasons
• use evidence-based reasoning to support a conclusion about what the data suggests

Success criteria

Students can:

• correctly explain weather vs climate using an example
• describe at least one pattern or trend from a weather chart
• point out one anomaly and explain why it might be unusual
• write a short, evidence-based statement (claim + evidence + reason)

Curriculum links

• Science Inquiry Skills: analyse data and information to describe patterns, trends and relationships and identify anomalies
• Science Inquiry Skills: develop evidence-based arguments to support conclusions or evaluate claims using secondary data appropriately
• Earth and Space (Year 8): use data to describe and interpret Earth systems, including weather phenomena and longer-term climate patterns

Lesson structure (30 minutes)

1. 0–4 min · Starter hook. Teacher shows two short scenario cards: “Today is stormy with 28°C” and “This area averages warm summers with frequent thunderstorms in January.” Students sort each card into “weather” or “climate” and explain their choice in one sentence.

2. 4–10 min · Mini-teach: key ideas and language. Teacher models a clear definition: weather is short-term conditions of the atmosphere at a specific time/place; climate is long-term patterns (often described using averages and typical ranges). Teacher introduces data vocabulary: pattern, trend, anomaly (unexpected result), and evidence.

3. 10–18 min · Data investigation: local weather snapshot. Teacher provides a simple “local weather snapshot” table for the past 14 days (e.g., daily max temperature, rainfall yes/no, and wind observations as brief codes). Students:

• plot the max temperatures as a line or bar graph (paper or digital)
• circle where the pattern changes (e.g., a run of warm days, then cooler days)
• identify one anomaly (a day that clearly stands out compared to neighbours)

4. 18–24 min · Guided analysis: patterns vs causes. Teacher asks structured questions on the board:

• What is the most common temperature range?
• Is there a trend across the 14 days? (up, down, or mixed)
• What makes the anomaly unusual? Students answer using “I notice… therefore…” sentence stems, referring to specific days or values.

5. 24–28 min · Evidence-based conclusion. Teacher provides a claim prompt: “Based on this data, the area is experiencing a warmer-than-usual period.” Students decide if the claim is supported by their evidence. If needed, teacher prompts: “What evidence would you need to compare ‘usual’?”

6. 28–30 min · Exit ticket. Students complete a 3-part exit ticket:

• Define weather and climate (one sentence each)
• Name one pattern from the graph
• Identify one anomaly and give one possible reason (e.g., a passing system, local variation)

Resources

• “Weather vs Climate” scenario cards (2–3 examples)
• A printed or digital weather data table for 14 days (max temperature, rainfall code, wind code)
• Graph paper and pencils (or tablets/computers for a simple spreadsheet/graph)
• Highlighters/markers for circling patterns and anomalies
• Sentence starters: “I notice…”, “This suggests…”, “An anomaly is… because…”

Assessment

• Formative during sorting: check for correct weather/climate classification and reasoning
• During graphing and questions: confirm students can identify patterns and a clear anomaly
• Exit ticket: evaluate definitions, pattern description, and evidence-based anomaly reasoning

Differentiation

• Support: provide a worked example of marking an anomaly using the same data format; offer sentence starters for every written response
• Language support: use a small word bank (pattern, trend, anomaly, short-term, long-term)
• Extension (optional within task): ask the student to propose what additional data (e.g., monthly averages) would be required to judge “usual”
• For EAL/SEN: allow verbal responses to be recorded by the teacher on the student’s behalf before a final short written sentence
