**A science teacher applies compound interest to explain real-world exponential growth: Five students invest $200 each in a sustainability fund with 8% annual interest, compounded annually. How much total will they have after 3 years?** When curiosity meets real-world math, one story stands out among financial trends: five students begin with a shared investment of $200 each in a sustainability fund designed to grow through compound interest. This isn’t just math—it’s a powerful example of exponential growth unfolding over time. What starts as a simple $1,000 starting point becomes a learning tool that many find both insightful and relevant today. As interest rates climb and sustainability fuels public interest, understanding how even modest investments grow can shape financial habits and awareness. --- ### Why “A science teacher applies compound interest to explain real-world exponential growth” is resonating now
