In this lesson, students explore the ways in which humans use hydropower to fuel society. First, they learn how we harness hydropower to generate electricity, and then they build a hydropaddle to simulate a turbine. Next, they examine the pros and cons of hydropower by choosing an issue, conducting an investigative analysis to discover a story of real-life impact, and sharing that story with the class. Students also reflect upon why facts alone are often not enough to communicate the importance of sustainability issues; asking questions and doing research can often lead to surprising changes in perspective and new understandings.
In this lesson, students learn about alternatives to fossil-fuel energy resources. They take on a challenge from the community’s “mayor” to serve on an Energy Task Force and research whether the most common alternative energy resources are appropriate for their community. Working in groups, they research five alternative energy sources and present their findings to the mayor. Then the groups evaluate the experience and the implications that each of these technologies has for both their local community and the larger global community.
In this lesson, students consider the various ways we illuminate our world. They conduct a scientific experiment to determine how much thermal energy various types of lightbulbs emit and consider the pros and cons of each light source. When they see that some types of bulbs are far more energy efficient than others, they consider the environmental implications of those more efficient options—hazardous waste. As students review the cost, energy use, lifespan, and disposal requirements of different kinds of bulbs, they learn that making thoughtful, considered choices about the products we use is an important aspect of sustainable intelligence.
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.
