Fourth-grade students at Bryant Ranch Elementary School recently deepened their understanding of renewable and nonrenewable energy through hands-on lessons in the TWIG science curriculum. After reading and annotating informational articles, students participated in a series of interactive experiments designed to demonstrate the advantages and disadvantages of each energy type.
To explore renewable energy, students constructed miniature wind turbines using motors, paper, corks, paper clips, and rubber bands. Through this activity, they observed how wind energy can be harnessed and converted into electricity, providing a tangible example of energy transfer.
In contrast, the class examined the environmental challenges associated with nonrenewable energy sources, focusing on oil spills. Students simulated an oil spill using a bowl of water and a “bird feather” to observe the harmful effects of oil on wildlife. They then experimented with various cleaning methods, such as rinsing with water and washing with dish soap, to determine the most effective way to remove oil.
These experiments culminated in a lively classroom debate about the benefits and drawbacks of renewable versus nonrenewable energy sources, encouraging students to apply critical thinking and evidence-based reasoning to their scientific learning.
