Sun and Life

Overview

This lesson (Lesson 11 of 20) builds on previous work about Earth–Sun interactions by focusing on what the Sun is like and why its energy is essential for life. Students will use simple data and visual information to identify patterns, relationships, and any anomalies.

Learning intentions

• Students will describe key characteristics of the Sun (as a star) and connect them to energy reaching Earth.
• Students will analyse provided data to identify patterns and possible outliers.
• Students will explain how the Sun’s energy supports life processes on Earth (directly or indirectly).

Success criteria

• I can describe the Sun as a star and name at least two of its characteristics.
• I can use data or a simple graph to describe a trend/pattern.
• I can identify an anomaly or outlier and suggest a reasonable reason it may occur.
• I can explain, in my own words, why the Sun is significant for life on Earth.

Curriculum links

• AC9S8I05 — analyse data and information to describe patterns, trends and relationships and identify anomalies.
• AC9S8I04 — select and construct appropriate representations, including tables and graphs, to organise and process data and information.
• AC9S8I01 — develop investigable questions, reasoned predictions and hypotheses to explore scientific models, identify patterns and test relationships.
• AC9S8I06 — analyse methods, conclusions and claims for assumptions, possible sources of error, conflicting evidence and unanswered questions.

Lesson structure (30 minutes)

1. 0–4 min · Retrieval hook. Teacher asks: “What does Earth get from the Sun, and what changes when Sun conditions change?” Students respond briefly and draw a quick “Earth receives →” concept map.
2. 4–10 min · Teacher input: Sun characteristics. Teacher shows a set of Sun facts (prepared slides/print) covering it as a star, relative size/temperature, and that it emits energy. Students complete a short “Sun profile” template: Star type, energy emitted, and where that energy ends up.
3. 10–16 min · Data analysis: pattern spotting. Teacher provides a small table or graph of “time of day vs temperature reading at the same location” OR “day vs solar panel output” (pre-made dataset with one unusual value). Students circle the overall trend and label the variables (independent/dependent) using sentence prompts.
4. 16–22 min · Identify anomaly and hypothesise. Teacher asks one guiding question: “Is there anything that doesn’t fit the pattern?” Students identify the outlier and write a hypothesis about a plausible cause (e.g. clouds, measurement timing, equipment variation) and state whether it suggests an error or a real-world event.
5. 22–27 min · Claims and reasoning. Teacher prompts students to connect Sun energy to life using an evidence sentence frame: “The Sun is significant for life because… This is supported by the trend in the data…”. Students share their reasoning; teacher clarifies any misconceptions.
6. 27–30 min · Exit ticket. Students answer two questions:

• “One pattern I noticed was…”
• “One anomaly/outlier I noticed was… I think it happened because…”

Resources

• Sun profile template (one page)
• Pre-made dataset table and a simple graph (printed or digital)
• Pen/pencil and highlighter
• Sentence starters for variables, trend description, and anomaly hypothesis
• Optional: short picture set showing Sun energy affecting Earth (solar panels, daylight/temperature)

Assessment

• Formative: teacher checks the “Sun profile” answers for accurate descriptions.
• Formative: teacher observes student explanations of trend and outlier reasoning during the discussion.
• Summative within the lesson: exit ticket responses (trend + anomaly cause) used to confirm understanding of patterns and significance.

Differentiation

• Support: provide worked example of identifying the independent/dependent variable; offer sentence starters and a word bank (star, energy, temperature, clouds, measurement).
• Stretch: ask for an extra step—students suggest one new piece of data that would help test their anomaly explanation (e.g. cloud cover, exact measurement time).
• Language support: allow brief oral responses recorded by the student on the worksheet using key words only.
• For a single student: teacher uses rapid checks and immediate feedback to keep pace and reduce waiting time.
