Bill Nye's scientific lecture about balance explains how something moves by giving it either a push or a pull. The size of its change relates to the strength or amount of force involving a push or pull.
Bill Nye sheds light on solar flares, eclipses, sunspots, fusion, and solar energy, and visits an enormous solar energy farm outside Sacramento, California, to demonstrate how the sun is the source of energy for all living things on Earth.
Bill Nye's lecture is all about our brain which physically understands the words we see and hear. It controls our heart, our oxygen, our body temperature, and even our stomach. Our brain smells, sees, thinks, moves, and remembers all kinds of things all the time as long as it operates everyday.
There's something in the air. Bill Nye's scientific lecture is all about the atmosphere, its five different levels, and how it protects the Earth. He also soars into the heavy topic of atmospheric air pressure and radio waves.
Bill Nye gets aerobic about the importance of respiration when he jogs, bikes, swims, and scuba dives. Discover how to measure how much air each breath contains, and make a model lung in a nifty home experiment. See a demonstration of how cigarette smoke can infiltrate and injure lungs.
