Quick check: causes, evidence and responses

A few quick questions on how human activity creates an energy imbalance, the indicators that show warming, and mitigation versus adaptation. Taught in class; use this to check yourself.

The Sun hasn't changed, but Earth is warming. What has?

Your teacher covers the causes, the evidence and the responses in class. These questions check the basics using the energy balance model from the lessons on screen.

ExplainUse the particle model to explain what you saw.

Human activity and imbalance

Does it add greenhouse gases to the atmosphere?

Burning coal for electricity
Clearing forests
Cattle and rice paddies (methane)
Planting forests
Wind turbines making electricity

How do more greenhouse gases create an energy imbalance?

ExplainUse the particle model to explain what you saw.

Indicators

Is it an indicator of climate change?

Rising global average air temperature
Rising sea level
Shrinking Arctic sea ice
Warming oceans
A single cold day in winter

How does the energy imbalance cause sea levels to rise?

A graph shows global average temperature rising over 100 years, with ups and downs. What does it show?

Why does shrinking Arctic sea ice make the Arctic warm faster than elsewhere?

ExplainUse the particle model to explain what you saw.

Responses

Is it mitigation or adaptation?

Replacing coal power with solar and wind
Planting trees to absorb carbon dioxide
Building sea walls
Growing drought-resistant crops
Heatwave warning systems

How does mitigation address the energy imbalance?

Why is adaptation needed even if emissions fall?

For teachers

A self-test on human causes of the energy imbalance, indicators of warming, and mitigation and adaptation (AC9S10U04, nodes 4 to 6, taught in class; nodes 4 and 5 hinges). About 16 minutes.

Open the teacher guide: answers, solutions, slides and a worksheet.

Students will be able to

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

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.

Where it leads

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