Renewable and Non-Renewable Energy Sources

Active learning works well for this topic because Year 7 students need to move beyond abstract definitions and confront real trade-offs. Comparing energy sources through hands-on tasks helps them see how environmental, economic, and geographic factors shape decisions, making the content memorable and relevant to their lives.

Learning Objectives

1. Compare the environmental impacts of renewable and non-renewable energy sources using specific data points.
2. Evaluate the sustainability of Australia's current energy mix, proposing evidence-based alternatives.
3. Analyze the economic and social factors influencing the transition to renewable energy in Australia.
4. Justify the importance of shifting towards renewable energy sources, citing at least two distinct environmental benefits.

Formal Debate

⏱ 25 min·Small Groups

Card Sort: Energy Source Match-Up

Provide cards listing energy sources, pros, cons, and impacts. In small groups, students sort into renewable or non-renewable categories, then match pros and cons to each source. Groups share one insight with the class to consolidate learning.

Prepare & details

Compare the advantages and disadvantages of renewable and non-renewable energy sources.

Facilitation Tip: During Card Sort: Energy Source Match-Up, circulate and listen for students to justify their groupings with environmental or practical reasons, not just labels.

Setup: Two teams facing each other, audience seating for the rest

Formal Debate

⏱ 40 min·Pairs

Debate Pairs: Renewables vs Non-Renewables

Assign pairs one side to research advantages and disadvantages using provided fact sheets. Pairs debate against another pair, with the class voting on strongest arguments based on evidence. Follow with a whole-class reflection on sustainability.

Prepare & details

Analyze the environmental impact of burning fossil fuels.

Facilitation Tip: For Debate Pairs: Renewables vs Non-Renewables, provide sentence starters on the board to scaffold evidence-based claims and rebuttals.

Stations Rotation

⏱ 45 min·Small Groups

Stations Rotation: Energy Impact Models

Set up stations for coal combustion (baking soda vinegar for CO2), solar oven build (foil and boxes), wind turbine spin (fan and pins), and hydro flow (water wheel). Groups rotate, observe, and record environmental pros and cons.

Prepare & details

Justify the importance of transitioning to renewable energy sources.

Facilitation Tip: At Station Rotation: Energy Impact Models, model how to rotate quietly and respect the setup so groups can focus on the data rather than logistics.

Setup: Tables/desks arranged in 4-6 distinct stations around room

Materials: Station instruction cards, Different materials per station, Rotation timer

Formal Debate

⏱ 30 min·Small Groups

Graphing: Australia's Energy Data

Distribute graphs of Australia's energy mix over time. Individually plot trends, then in small groups discuss implications for fossil fuel decline and renewable rise. Present findings to class.

Prepare & details

Compare the advantages and disadvantages of renewable and non-renewable energy sources.

Facilitation Tip: When Graphing: Australia's Energy Data, ask early finishers to double-check their scales and labels before moving to the discussion phase.

Teaching This Topic

Start with hands-on experiences to build schema before abstract discussion. Avoid overwhelming students with too many sources at once; focus on solar, wind, and coal first, then introduce others. Research shows students grasp energy concepts better when they see immediate cause-and-effect, like combustion demos or wind turbine models, rather than only hearing lectures about pollution.

What to Expect

By the end of these activities, students will confidently categorize energy sources, explain at least three trade-offs for each, and justify why Australia’s energy mix matters. They should use data to support arguments and recognize that no single source solves everything.

Watch Out for These Misconceptions

Common Misconception

During Card Sort: Energy Source Match-Up, watch for students to assume renewables have no environmental impacts.

What to Teach Instead

Use the card sort’s sample cards to prompt discussion: ask groups to find at least one environmental trade-off for solar, wind, and hydroelectric power, and one advantage for fossil fuels, to balance their evaluation.

Common Misconception

During Station Rotation: Energy Impact Models, watch for students to believe burning fossil fuels is clean because it produces heat and light.

What to Teach Instead

Use the combustion demo station to have students test air quality with litmus paper or simple CO2 indicators before and after burning coal or wood, then ask them to revise their initial ideas in small groups.

Common Misconception

During Graphing: Australia's Energy Data, watch for students to think all renewable sources are equally effective in every region.

Assessment Ideas

Discussion Prompt

After Debate Pairs: Renewables vs Non-Renewables, pose the question: 'If Australia has abundant sunshine and wind, why is transitioning to 100% renewable energy challenging?' Use the debate pairs’ arguments to guide students toward economic, infrastructure, and reliability factors, referencing specific Australian projects or regions.

Quick Check

During Card Sort: Energy Source Match-Up, provide students with a T-chart. Ask them to list three advantages and three disadvantages for both renewable and non-renewable energy sources, using examples relevant to Australia such as the Hunter Valley’s coal industry or South Australia’s wind farms.

Exit Ticket

After Graphing: Australia's Energy Data, have students write one sentence explaining the primary environmental impact of burning coal. Then, ask them to write one sentence justifying why Australia should invest more in solar power, referencing a specific benefit from the data they graphed.

Extensions & Scaffolding

• Challenge early finishers to design a hybrid energy plan for their local area, balancing cost, reliability, and environmental impact using real data from the Graphing station.
• Scaffolding for struggling students: Provide a partially completed T-chart during the Card Sort, with two advantages and two disadvantages filled in for solar and coal to guide their thinking.
• Deeper exploration: Invite students to research one Australian renewable energy project, such as a solar farm in Queensland or a wind farm in Victoria, and present a 2-minute case study to the class.

Key Vocabulary

Renewable Energy	Energy derived from natural resources that replenish themselves over time, such as solar, wind, and hydropower.
Non-Renewable Energy	Energy derived from finite resources that are consumed much faster than they can be regenerated, including fossil fuels like coal, oil, and natural gas.
Sustainability	The ability to maintain or improve something, in this context, energy use, without depleting resources for future generations or causing irreversible environmental damage.
Greenhouse Gases	Gases in the atmosphere, such as carbon dioxide and methane, that trap heat and contribute to global warming and climate change.
Fossil Fuels	Natural fuels, such as coal or gas, formed in the geological past from the remains of living organisms.
