Understanding Lightning and Sound Phenomena

Sonia, a science enthusiast, shares her curiosity-driven approach to learning about science. She discusses the phenomena of lightning and thunder, explaining the science behind them, including the role of plasma. The video compares the speed of light and sound, illustrating why we see lightning before hearing thunder. Sonia introduces the concept of lightning rods and encourages viewers to explore interactive simulations on the CK-12 platform. The video concludes with an invitation to further explore related scientific concepts and questions.
