Climate change is a pressing issue that affects everyone on the planet. As temperatures rise and extreme weather events become more common, it is crucial for the younger generation to understand the science behind climate change and explore innovative solutions to combat it. In a high school classroom in Bloomington, Indiana, science teacher Kirstin Milks is leading the way in educating her students about human-caused climate change and inspiring them to think creatively about technologies that could help reduce greenhouse gas emissions.
Milks, along with climate scientist Ben Kravitz and colleague Paul Goddard from Indiana University, has developed a lesson that challenges students to come up with bold ideas to address climate change. The lesson aims to empower students with knowledge and creative freedom, allowing them to envision a better future for the planet. With heat waves and extreme weather events becoming more frequent, Milks believes it is essential for students to understand the impact of climate change and explore ways to make a difference.
The lesson begins with a discussion on the basic facts of human-caused climate change, emphasizing the role of burning fossil fuels in increasing carbon dioxide levels in the atmosphere. Students learn about the importance of reducing greenhouse gas emissions to combat climate change. While solar and wind energy, along with battery storage, are helping transition away from fossil fuels, Kravitz highlights the need for faster action to address the climate crisis.
To supplement traditional solutions, Kravitz introduces the concept of climate engineering, or geoengineering, as a potential strategy to temporarily alter the Earth’s climate and mitigate the effects of climate change. This approach includes reflecting sunlight back into space and removing carbon dioxide from the atmosphere. However, these strategies come with risks and uncertainties, underscoring the importance of informed decision-making.
In the classroom, students are encouraged to think creatively and develop innovative ideas to slow global warming. From solar-powered helicopters to artificial trees that store rainwater, students brainstorm a variety of solutions, including covering the desert in glitter to reflect light back into the atmosphere. As they refine their ideas, they consider potential limitations and risks, fostering critical thinking and problem-solving skills.
For their final assignment, students present their concepts to Kravitz, Goddard, and other scientists, showcasing their understanding of the benefits and risks associated with their proposed solutions. One student, Campbell Brown, presents an idea for a flying air filter that extracts carbon dioxide from the atmosphere and converts it into a harmless byproduct. While the technology is currently expensive, Kravitz assures her that the concept is viable, instilling a sense of optimism and empowerment in the students.
Through this lesson, students like Brown and senior Emerald Yee gain a deeper understanding of climate change and the potential for innovative solutions to address it. Yee, who has personal concerns about the impact of climate change on her family, appreciates the opportunity to explore ways to make a positive impact on the environment for future generations. By fostering climate optimism and encouraging creative thinking, Milks, Kravitz, and Goddard are equipping students with the knowledge and skills needed to tackle the challenges of climate change and create a more sustainable future for all.
