Before class

A Quick check: a few questions on what students should know for AC9S10U04 nodes 4, 5 and 6, which you teach in class. It has no board, no clip and no new teaching, and it is optional, so it never holds up course completion. Set the width with ?width=minimum, typical (default) or wider.

Use it as a self-test after your teaching, a starter, or revision. Sunlight, energy balance and the greenhouse effect are on screen (nodes 1 to 3). Climate data graphs, local impacts and the evaluation of strategies are for class. Responses involve values as well as science; present the evidence and options, and let students argue their positions.

Running the lesson

  1. Node 4: ask students to explain the imbalance using the in and out arrows before choosing an option.
  2. Node 6: ask for one mitigation and one adaptation for a local issue (bushfire, drought).

The hard part (on purpose)

Linking each indicator back to energy. When a student just names an indicator, ask where the extra energy goes.

When students get stuck

What you will seeA question to askThe fix
A student says one cold day shows warming is not happening.Is that weather or climate?Weather. Climate is the long-term average trend.
A student says adaptation and mitigation are the same.Does a sea wall change the greenhouse gases?No. Mitigation changes the cause; adaptation limits the harm.

Answers to the checks

  1. Adds or not?: Does it add greenhouse gases to the atmosphere?
    Burning coal for electricity → Adds greenhouse gases; Clearing forests → Adds greenhouse gases; Cattle and rice paddies (methane) → Adds greenhouse gases; Planting forests → Does not add them; Wind turbines making electricity → Does not add them
  2. The imbalance: How do more greenhouse gases create an energy imbalance?
    They trap more outgoing radiation, so Earth absorbs more energy than it sends to space
    Incoming energy stays about the same, but less escapes. With energy in greater than out, Earth warms until it balances again.
  3. Indicator or not?: Is it an indicator of climate change?
    Rising global average air temperature → Indicator; Rising sea level → Indicator; Shrinking Arctic sea ice → Indicator; Warming oceans → Indicator; A single cold day in winter → Not an indicator
  4. Sea level: How does the energy imbalance cause sea levels to rise?
    Warmer water expands, and melting land ice adds water
    Extra energy warms the oceans and melts glaciers and ice sheets on land, both raising the sea.
  5. Reading a graph: A graph shows global average temperature rising over 100 years, with ups and downs. What does it show?
    A long-term warming trend, with natural year-to-year variation
    The trend is the key. Yearly ups and downs are normal weather and climate variability on top of it.
  6. Melting ice: Why does shrinking Arctic sea ice make the Arctic warm faster than elsewhere?
    Dark open ocean absorbs sunlight that the white ice used to reflect, so more energy goes in
    Less ice lowers the albedo, so more sunlight is absorbed, which melts more ice. This is why the Arctic is warming faster than the global average.
  7. Mitigation or adaptation?: Is it mitigation or adaptation?
    Replacing coal power with solar and wind → Mitigation; Planting trees to absorb carbon dioxide → Mitigation; Building sea walls → Adaptation; Growing drought-resistant crops → Adaptation; Heatwave warning systems → Adaptation
  8. In terms of the model: How does mitigation address the energy imbalance?
    It reduces greenhouse gas emissions, so less outgoing radiation is trapped
    Cutting emissions (or removing carbon dioxide) reduces the extra trapping, so energy in and out come closer to balance.
  9. Why adapt as well?: Why is adaptation needed even if emissions fall?
    Warming and its effects already under way continue for some time, so people need to cope with them
    Greenhouse gases already in the air, and heat already in the oceans, keep warming and sea level rising for decades.

Stretch and support

Stretch: Choose a strategy (carbon capture, electric vehicles, mangrove restoration) and evaluate it: what does it change in the energy balance, and what are its limits?

Support: Give the energy diagram with in and out arrows and ask where each strategy acts.

Coach prompt (optional)

For a student who has done the lesson and is still stuck. They paste it into an AI tool your school allows; it asks questions about this lesson's one idea and doesn't give answers. Students see it on the course recap page only through a link ending in ?coach=1: recap with coach prompts.

You are a patient science coach for a Year 10 student in Australia. Help me understand the ideas in ONE lesson only, from the lesson "Quick check: causes, evidence and responses".

The ideas:
- Human activity, greenhouse gas concentrations and energy imbalance: I can explain how human activities increase atmospheric greenhouse gas concentrations and describe how this creates an energy imbalance that drives warming.
- Indicators of climate change across Earth's spheres: I can identify and interpret multiple indicators of climate change and explain each as evidence of the energy imbalance described in N4.
- Using energy flow models to explain and evaluate responses to climate change: I can use the energy flow model to explain patterns of global climate change and evaluate strategies designed to reduce or mitigate its effects in terms of the model.

What understanding looks like:
- Identifies at least two human activities that increase atmospheric greenhouse gas concentrations
- Explains how increased greenhouse gas concentration leads to a positive energy imbalance
- Connects the perturbation of atmospheric CO₂ to the energy flow model from N2 and N3
- Names at least three distinct climate change indicators across different spheres
- Explains the mechanism behind at least two indicators using the energy flow model
- Interprets a climate data visualisation as evidence of energy imbalance
- Applies the energy flow model to explain at least two distinct patterns of global climate change
- Evaluates at least one strategy to reduce climate change and one to mitigate its effects using the model
- Distinguishes mitigation from adaptation and explains each in terms of the energy balance

Mistakes students often make here:
- A student says one cold day shows warming is not happening.
- A student says adaptation and mitigation are the same.

How to coach me (rules from the Waypoints Kit coach):
- Ask me one short question at a time (2 to 4 sentences) and wait for my answer. Never give me the answer before you have heard my thinking, and don't hide the answer inside your question.
- Start in Discover: ask me to explain the idea in my own words, or to predict what happens in a simple example. I can switch any time: "teach it back" (you play a beginner and I explain), "spot the flaw" (you show me an answer with one common mistake and I find it), or "check" (I explain, and you tell me what is solid and what to revisit).
- If I am stuck or say "just tell me", ask what I think first, then give a small hint or a simpler example. Explain only after I have had a real go.
- If I seem to be missing the idea that comes before this one (The greenhouse effect — trapping outgoing radiation), check it quickly, then come back.
- Stay in this idea: don't teach later ideas or add extra content. If I ask about something else, say it is for another lesson and bring me back.
- After you help, ask me one reflective question, such as how I know my answer is right or what I would check.
- Praise my effort and method, not my ability.
- You can be wrong: if I rely on something you said, remind me to check it against my notes or the lesson. If you don't know, say so.
- Use simple words.
- Stop when I can explain the idea in my own words and get one new example right. Then tell me to go back to the lesson "Quick check: causes, evidence and responses".

Exit ticket

Give one mitigation and one adaptation, and say how they differ.

Mitigation reduces the cause (e.g. renewable energy). Adaptation limits the harm (e.g. sea walls).

What each step is for

Where it leads

Back in class: analyse a real temperature or sea-ice graph; debate or evaluate a response strategy using the model.
