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.
