Eureka! Episode 20 - Measuring Temperature
Eureka! shows viewers how Swedish scientist Anders Celsius invented the Celsius thermometer, using the expansion of mercury as a measure of tempera...
-
Eureka! Episode 19 - Expansion and Contraction
Using balloons to illustrate the process, Eureka! shows how, when matter gets hot, its molecules go faster and the solid, liquid, or gas expands. C...
-
Eureka! Episode 18 - Evaporation and Condensation
A goldfish bowl filled with water demonstrates the process of evaporation, in which speeding molecules escape from a liquid to form a gas.
-
Eureka! Episode 17 - Molecules in Liquid
As molecules in a solid get hotter, they vibrate faster and faster and eventually slip out of their lattice-work pattern. When this occurs, the sub...
-
Eureka! Episode 16 - Molecules in Solids
This program defines the three states of matter, and illustrates the lattice-work pattern of molecules in solids. Viewers learn the origin of the w...
-
Eureka! Episode 15 - The Pulley
Eureka! shows viewers how a pulley works to lift a heavy object. If you double the number of ropes supporting the weight, you double the mechanical...
-
Eureka! Episode 14 - The Screw and The Wheel
This program provides examples and definitions of a screw and a wheel; a screw is simply a twisted inclined plane; a wheel is simply a circular lev...
-
Eureka! Episode 13 - Mechanical Advantage and Friction
Professors A and B compare the mechanical advantage of an inclined plane with that of a lever.

Eureka! Episode 12 - The Lever
Eureka! demonstrates the principle of the lever: "The longer the arm of the lever to which force is applied, the less that force need be."
-
Eureka! Episode 11 - The Inclined Plane
This program demonstrates how an inclined plane allows you to trade increased distance for decreased force
-
Eureka! Episode 10 - Potential Energy
A rock teetering on the edge of a cliff is shown to have potential energy - the energy of position.
-
Eureka! Episode 9 - Kinetic Energy
Animated billiard balls help demonstrate kinetic energy - the energy of motion.
-
Eureka! Episode 8 - Work
A circus strongman and a clown help present the physics definition of work. Concept: Work = force x distance.
-
Eureka! Episode 7 - Weight vs. Mass
Eureka! explains the difference between weight and mass, and shows how only mass is the same on the moon and on the earth.
-
Eureka! Episode 6 - Gravity
Isaac Newton's celebrated falling apple is cited to explain the force of gravity and the unit with which the force of gravity is measured. Concept:...
-
Eureka! Episode 5 - Acceleration Part II
An animated locomotive helps explain how acceleration works and is calculated. The importance of reasonable units is stressed. Concept: Acceleratio...

Eureka! Episode 4 - Acceleration Part I
With the examples of a bicycle and a baseball player, an important rule of physics becomes apparent. Concept: Force = mass x acceleration.
-
Eureka! Episode 1 - Inertia
This program introduces the series and sets forth the concept of inertia, the first law of physics: Things like to keep on doing what they're alrea...
-
Eureka! Episode 3 - Speed
The concept of speed is introduced to the inertia-mass relationship. Concept: Force varies with mass and rate of change of speed
-
Eureka! Episode 2 - Mass
Building on the concept of inertia, Eureka! adds the factor of mass, tells how it's measured, and shows how it differs from size. Concept: Inertia ...
