Passive Solar Energy Concepts

In a seventh-grade science class, students explore alternative energy by designing passive solar houses. Passive solar energy, which comes directly from the sun, is used for heating, cooling, and lighting. Students learn to build houses using high thermal mass materials like brick and concrete to regulate temperature. For summer homes, they use design strategies such as roof overhangs and insulating shutters. The class conducts experiments to test the effectiveness of their designs in maintaining desired temperatures, engaging in friendly competition to enhance learning.
