In this lesson, students learn that framing our energy habits and choices in terms of a “carbon footprint” can help us understand our individual impact on the global environment. They conduct a personal eco-audit to investigate how their own energy usage results in carbon being released into the atmosphere. After tracking their habits for one 24-hour period, students calculate their personal carbon footprint and then compare the results to averages for other countries and communities. As students frame their choices in a global context and come to understand the importance of making sustainable choices for a healthier future, they also look for ways to support each other and create exciting and innovative changes for the future.
In this lesson, students learn that nuclear energy is powerful enough to send a robot on a scientific mission millions of kilometers (miles) away and to supply large amounts of electricity on Earth with minimal impacts on natural resources. They also learn that harnessing the power of the atom has consequences—some very serious and long-term consequences. Rather than telling students what to think about the issue, the lesson encourages students to research the topic and then debate their peers. The lesson concludes with a discussion designed to help students synthesize their thoughts on the topic.
This lesson begins with students learning about natural resources that humans either dig (such as coal) or pump (such oil or natural gas) from the Earth’s crust. Students discuss why these resources are so valuable to us and why we tolerate the many adverse side effects of extracting and using them. They then discuss how renewable energy sources are being used as alternatives in many areas around the world. Next, students simulate a mining experience by digging into a chocolate chip cookie. The experience leads to a rich discussion about safety, fines, rewards, and reclamation.
At the end of Module One, students accurately input their first meter reading into the STEMhero software and create a plan for collecting at least three more readings to establish a baseline of their actual water and/or energy consumption.
