S02E01 The Inclined Plane 1981-01-01 5m
How can someone lift a very heavy load? If one could slice the load into pieces, that would trade increased distance for decreased effort. But since one can't break things because they are so heavy, the inclined plane comes into play. more
S02E02 The Lever 5m
A teeter-totter is the perfect demonstration of the lever, particularly if you are trying to ride a teeter-totter with someone heavier than you. Such is the Principle of the Lever. more
S02E03 Mechanical Advantage and Friction 5m
Two professors compete to see who can lift a book with a lesser amount of force. The professor who uses a lever is more efficient than the inclined plane, once we factor in a basic double-edged sword called friction. more
S02E04 The Screw and the Wheel 5m
All machines in the world can be traced to just two: the inclined plane and the lever. Even the wheel is just a circular lever whose fulcrum has become an axle. The screw? It's just a spiraling inclined plane. more
S02E05 The Pulley 5m
Jack and Jill went up the hill and found a problem: how can they pull a pail of water from the bottom of a well? In this expanded nursery story, we find there is more to a pulley–and its mechanical advantage–than meets the eye. more
S02E06 Molecules in Solids 5m
The first of six shows on heat and temperature, introduces molecules. Even though a solid object looks motionless, its molecules move back and forth in a lattice-work dance. more
S02E07 Molecules in Liquids 5m
This episode sacrifices a chocolate rabbit on a hot day to illustrate the movement of molecules in liquids. more
S02E08 Evaporation and Condensation 5m
No end of problems await the man who keeps fish for pets. Evaporation forces one to refill the tank. And he who thinks he can outsmart water vapor by keeping his fish in a refrigerated water tank, falls prey to Nature's countermeasure: condensation. more
S02E09 Expansion and Contraction 5m
This lecture-packed show compares a balloon to a bunch of angry wasps to explain why gases expand and contract. It goes further than that. The expansion process also affects matter when it changes from one state to another. more
S02E10 Measuring Temperature 5m
Given three bathtubs of varying temperature, the star of the show ""blunts"" his feet so that they can't tell temperature. Sure they can't. The human body can only tell changes in temperature in comparison to what it had been used to. It's up to an independent device: a thermometer and the scale devised by Anders Celsius. more
S02E11 Temperature vs. Heat 5m
What is better to warm up a kiddie pool: a teacup of boiling water (100° Celsius) or a bucket of water at 50° Celsius? The answer tells you the difference between temperature and heat. more
S02E12 Atoms 5m
There's more to matter than the molecules we had spent discussing in the previous six shows. This fourth unit produces that first look at atoms. more
S02E13 Electrons 5m
An atom is made of mostly empty space. The electrons in an atom zoom around at fantastic speeds to create existence out of something that is mostly nothingness (at the atomic level). more
S02E14 Conduction 5m
All objects conduct heat, of course, but get a look at objects from the atomic level and you'll see why some objects conduct heat faster than others. more
S02E15 Volume and Density 5m
To set up audiences for The Convection of Heat, this question is posed: how can you fit eight junky cars into a small space? more
S02E16 Buoyancy 5m
How come an anchor is easier to lift if it's in the water than in open air? It lies in the density of an object versus a certain quantity of water. more
S02E17 Convection 5m
Now that the Principle of Buoyancy is understood, one can fully grasp The Convection of Heat. This is demonstrated with a furnace not being in the attic of a house. more
S02E18 Heat as Energy 5m
An animated Count Rumford demonstrates, for the first time, how heat can be used to produce energy. The show converts a Calorie as the amount produced from 4200 joules of work. more
S02E19 Radiation Waves 5m
Why does somebody stand in the shade on a hot day? This show introduces the third method by which heat can be transferred: radiation. more
S02E20 The Radiation Spectrum 5m
Is it just your imagination that you are warmer when you wear dark clothes over white clothes? That actually sets off a reveliation on what color really is. more
