  • Pit crew station filled with tires at a racetrack. Caption: Friction is necessary for breaks and tires to work.

    Friction always creates heat. Brakes and tires depend on friction to work, but friction can also damage a car's mechanics. For example, the engine is susceptible to the heat caused by friction, and mechanics devise ways to protect against friction while trying to get the greatest amount of horsepower without damaging the car. Part of "The Science of Speed" series.

  • A snake with eyes covered. Caption: this snake strikes its prey with pinpoint precision.

    The goal of this research is to determine the mechanisms underlying predatory and defensive behavior guided by an extraordinarily novel sensor in snakes. Pit vipers, pythons and boas possess special organs that form images in the brain of the thermal environment, much like vision occurs in the human brain. Thus, these snakes see heat, and this amazing system is the most sensitive infrared detector on Earth, natural or artificial. A better understanding of infrared-based thermal imaging in snakes is important not only for understanding complex behavior in these highly efficient predators, but also for understanding the evolution of imaging sensors and the behaviors they support in other animals including people.

  • Using Energy

    • Video
    Illustration of the sun sending heat into space and that heat hitting the Earth. Caption: So how is the sun able to heat the earth?

    Teaches caveman Zog that people use energy in one of two main ways: by moving heat from one place to another (conduction, convection, or radiation) or by transferring energy from one form to another by using an appliance, like a lamp or car. Appliances always waste some energy, and Zog learns why energy efficient appliances are the best choices people have today. As only a caveman can, Zog provides plenty of laughs along the way to finding clever and complete answers to elementary energy questions.

  • The magic school bus on arctic ice with walrus outside. Caption: Don’t mean to be rude, but you're too heavy!

    The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. "Where did the hot go?" wonders Arnold when he finds that his hot cocoa has cooled. In response, Ms. Frizzle whisks the class to the Arctic. What's the freezing Arctic got to do with heat? While the kids try to find out, the bus's engine freezes and the bus floats away. As the bus moves away, so does the heat from everyone's body. How can Ms. Frizzle's kids insulate their body to keep the heat in?

  • Light brown earth dotted with low lying shrub brush. Caption: (narrator) The typical desert seems to be hot and dry deserts,

    Deserts are some of the harshest environments in the world. They can be found just about anywhere water is scarce, including in tropical rain forests and even in cold and snowy Antarctica. When most people think of deserts, they immediately think of scorching heat. However, it takes more than heat alone to create a desert. While each desert is unique, all share commonalities: they are dry, windy, arid lands with little annual rainfall.
