The young man sitting in the high school physics and chemistry lab is dressed in a lab coat and safety goggles. He is holding an experiment apparatus in his hand, and the students around him are paying close attention as he explains the physics principle behind it. He speaks in a clear and concise manner, using simple terms and diagrams to make the concept easy to understand. The students are engaged and ask questions as he sets up the experiment. The lab is filled with the sounds of bubbling liquids and the faint smell of chemicals as the students work together, under the young man's guidance, to understand the physics principle being demonstrated
