This educational video from the Lighthouse Lab introduces students to the fundamental concepts of thermal energy, particle theory, and heat transfer. Hosted by Sophie Taylor-Pritchard, the lesson begins by defining matter as being made of tiny particles that are always in motion, explaining that the amount of this motion is what we call thermal energy. Through clear animations, students visualize how increased thermal energy leads to faster particle movement and higher temperatures. The video features two distinct demonstrations to reinforce these concepts. First, the host measures the temperature of three water cups (icy, warm, and hot) to illustrate the relationship between temperature readings and the amount of thermal energy present. Second, a classic conduction experiment is performed using a metal rod, a burner, and wax-attached candles to visually demonstrate the direction of heat flow.
