The Bill Nye Heat Worksheet available for download at the links above follow along as Nye talks about how everything is made of molecules. Students see firsthand that no matter what there in (solid, liquid, or gas) molecules are constantly moving. Nye explains that the speed of the molecules depends on their temperature and student’s record answers on their Bill Nye Heat Worksheet. Nye then goes on to further explain that cold things have slow-moving molecules, while hot things have fast-moving molecules. Students see that that temperature is a measurement of molecule speed.Nye details that heat moves in three different ways (conduction, convection, radiation). Students observe on the worksheet conduction is the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material. Bill Nye explains that convection is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat. Students answer on their Bill Nye Heat Worksheet that radiation is the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
