Launch
Lesson 1 • Exploring bushfires
Students examine the prevalence of bushfires, their causes and how people are impacted.
Inquire
Lesson 2 • Fire and combustion reactions
Students conduct a series of activities that explore the reactants and products of a combustion reaction.
Lesson 3 • Carbon dioxide and the carbon cycle
Students model the movement of carbon dioxide produced by combustion through the atmosphere, hydrosphere, biosphere, and geosphere.
Lesson 4 • Measuring biomass
Students measure the biomass in a tree and use a spreadsheet to determine the corresponding amount of carbon dioxide removed from the atmosphere.
Lesson 5 • Ice core evidence
Students analyse 800,000 years of carbon dioxide data and correlate this to changing global temperatures. Students examine how changes in greenhouse gases affect the likelihood of bushfires.
Lesson 5A • Correlating carbon dioxide levels and global temperatures
Students correlate variations in carbon dioxide levels in the atmosphere with global temperature variations.
Lesson 6 • Factors affecting the rate and intensity of bushfires
Students use secondary data to identify the factors that affect the speed a fire travels. They apply their understanding to evaluate a fire with unknown conditions.
Act
Lesson 7 • Design to survive
Students apply their understanding to design a fire action plan for a selected audience and/or present a local plan to reduce the level of carbon dioxide in the atmosphere.

Curriculum and syllabus alignment
Year 9
By the end of Year 9 students explain how interactions within and between Earth’s spheres affect the carbon cycle. They explain the role of publication and peer review in the development of scientific knowledge and explain the relationship between science, technologies and engineering. They analyse the different ways in which science and society are interconnected.
Students plan and conduct safe, reproducible investigations to test or identify relationships and models. They describe how they have addressed any ethical and intercultural considerations when generating or using primary and secondary data. They select and use equipment to generate and record replicable data with precision. They select and construct appropriate representations to organise, process and summarise data and information. They analyse and connect data and information to identify and explain patterns, trends, relationships and anomalies. They analyse the impact of assumptions and sources of error in methods and evaluate the validity of conclusions and claims. They construct logical arguments based on evidence to support conclusions and evaluate claims. They select and use content, language and text features effectively to achieve their purpose when communicating their ideas, findings and arguments to specific audiences.

Teaching notes
- Read through the teaching sequence.
- Note any adaptations you would like to make to suit your schools and students’ context.
- Consider how this teaching sequence will assess the curriculum standards. Two options are provided:
- A combination of formative assessment and summative assessment of smaller tasks throughout the teaching sequence, and a Fire Plan as the Act phase, or
- The Act phase involves two summative assessment tasks including a Fire Plan AND a plan to reduce the level of carbon dioxide in the atmosphere, thereby reducing the frequency of bushfires in the future.
- Check that your IT department will allow access to the YouTube videos.
- Complete the ordering of laboratory equipment and rooms (if required).
- Ensure that students can access the excel data spreadsheet required for Lessons 3 and 4.
- Consider the audience you select for students to communicate with.
- It may not be appropriate to select an earlier year level, as developmentally the concepts covered are not appropriate. It also diminishes the repeatability of the sequence, as students in earlier year levels will have already ‘learned’ (albeit in a non-experiential way) about the concepts.
- Presenting to an external audience, for example, local fire service will allow the Year 9 students to not only receive feedback on their science communication skills but also on the accuracy of their information.
- You might also consider asking students to communicate with a parent audience as part of an ‘open-day’ or ‘science-fair’ type experience.
What else might help you prepare to teach this sequence?
- The background science of bushfires: https://www.youtube.com/watch?v=l38UkQmUISs
- Watch https://iview.abc.net.au/show/big-weather-and-how-to-survive-it or https://knowledge.aidr.org.au/resources/big-weather/
- Discussing the key concepts with teachers working in humanities or mathematics to develop a transdisciplinary approach.
- Visits to areas previously affected by bushfire: when considering this, deliberate on the impact on students and the local community.
Lab tech notes—Lesson 2
Lesson 2 requires students to complete a series of activities that explore combustion. There is also an option for teachers to provide a fire demonstration. As required in all states, teachers must prepare their risk assessments of the activities. Some of the risks that need to be considered are listed below.
Flour and fire demonstration
- Flour dust is highly flammable.
- Use controlled amounts of flour dust.
- Consider the direction of the flame and any barriers that could be used to reduce risk.
- Consider if students will mimic the activity.
- Identify the location of fire alarms.
- Remove all flammable materials from around the candle including clothing, books, paper, curtains, flammable decorations, or liquids.
- Limit drafts, vents, or ceiling fans to reduce the risk of items blowing into the flame.
- Ensure an appropriate fire extinguisher or fire blanket is available and accessible at all times.
- Know appropriate first aid in case of a burn.
- Discuss the appropriateness of the risk with the school authorities.
Lime water
- Add 2-3 heaped spatulas of calcium hydroxide into a 500 mL stock bottle and make up with distilled water. Mix well and allow the solids to settle. Filter the mixture to remove the solids.
- Use safety glasses when working with lime water.
- When using a straw to blow into lime water, ensure that you do not suck up the water into the mouth.
- If ingested, immediately dilute with drinking water.
- Wash hands after handling.
- If the lime water makes contact with the skin, wash with running water.
- Remind students not to mimic the teacher in drinking the lime water.
Candles
- Use quality, reliable candles as cheaper candles will burn down quickly and bring the flame into contact with flammable materials.
- Remove all flammable materials from around the candle including clothing, books, paper, curtains, flammable decorations, or liquids.
- Use candles in low-traffic areas and limit the number of people in the area.
- Place the candles on stable, heat-resistant surfaces.
- Only move candles that have been cooled (with solid wax).
- Limit drafts, vents, or ceiling fans to reduce the risk of items blowing into the flame.
- Use stable candleholders made of non-combustible materials.
- Never leave a burning candle unattended.
- Ensure the jars that fit over the candle are large enough to be placed without risking burning fingers.
- Ensure an appropriate fire extinguisher or fire blanket is available and accessible at all times.
- Know appropriate first aid in case of a burn.
