In the firts lesson, students investigated the greenhouse effect by measuring temperature changes in two glass jars. One jar was covered with plastic wrap to simulate the Earth's atmosphere trapping heat, while the other remained uncovered. Both jars were placed under a lamp, representing the Sun.
Students began by recording the initial temperature inside each jar. The lamp is then turned on for a set period, 10–15 minutes. During this time, students observed and recorded temperature changes at regular intervals.
After collecting the data, students compared the results. They found out that the covered jar retains more heat than the uncovered one, demonstrating how greenhouse gases trap heat in Earth's atmosphere. The lesson concluded with a discussion on the real-world implications of the greenhouse effect and climate change.
This hands-on experiment helped students understand the role of greenhouse gases in warming our planet.
The second lesson was even more challenging. Students built wind-solar power plant to investigate renewable energy sources.
They assembled a miniature wind turbine and a small solar panel, connecting both to LED bulb to use the generated electricity. By testing the setup under different conditions—such as varying wind speed (using a fan) and light intensity (with a lamp)—students observed how energy production changes. They recorded their findings, comparing the efficiency of wind and solar energy individually and combined. Finally, they discussed the advantages of hybrid renewable systems and their real-world applications.
