F2-23: BUOYANCY PARADOX - INVERTED BLOCK

Category: F2 Buoyancy
Purpose: Illustrate buoyancy in a paradoxical way.

F2-22: BUOYANCY PARADOX - ACCELERATED FRAME

Category: F2 Buoyancy
Purpose: Illustrate dramatically the concept of buoyancy.

F2-11: HYDROMETER

Category: F2 Buoyancy
Purpose: Measure the density of a liquid.

F2-10: BUOYANT BUBBLES

Category: F2 Buoyancy
Purpose: Demonstrate buoyancy and diffusion in an interesting way.

F2-04: BUOYANCY - SPHERE AND WATER

Category: F2 Buoyancy
Purpose: Challenge the students' thinking about the buoyant force by considering the question: "Will a round object, without a flat top and bottom surface, experience a buoyant force, as does a cylinder?"

F2-03: CARTESIAN DIVER - EXPLICIT VERSION

Category: F2 Buoyancy
Purpose: Demonstrate explicitly how a cartesian diver works by showing how the water enters the diver when the pressure in the cylinder is increased.

N3-41: SPLITTING OF SPECTRUM INTO COMPLEMENTARY COLORS

Category: N3 Color
Purpose: Show complementary colors by removing a band from the white light spectrum.

N3-33: MAXWELL'S EXPERIMENT - THREE-COLOR MIXING

Category: N3 Color
Purpose: Demonstrate three-color mixing with positive colors.

N3-31: COLOR SEPARATION TRANSPARENCIES

Category: N3 Color
Purpose: Illustrate color mixing of negative color transparencies.

F1-21: LIPLESS STRAW

Purpose: Demonstrate the role of atmospheric pressure in the operation of a drinking straw.

F1-15: PRESSURE GLOBE

Purpose: To illustrate several interesting phenomena related to air pressure

F1-14: PISTON DIAMETER VS TRAVEL - WORKING MODEL

Purpose: Show that with an incompressible fluid the bigger piston moves more slowly than the smaller piston.

D5-24: ROTATING PENDULA - LENGTH VS. HEIGHT

Purpose: Show that pendula of different length suspended from the same point rotating at the same angular speed rise to the same vertical height.

Purpose: Demonstrate the presence of a "critical parameter" which determines the dynamic behavior of a simple physical system.

D5-22: ROTATING PENDULUM

Purpose: Demonstrate the presence of a "critical parameter" which determines the dynamic behavior of a simple physical system.

D5-21: BALL ROLLING ON ROTATING DISC

Purpose: Show that a sphere rolling on a rotating disc will move in circles.

F1-13: CONSTANT WATER PRESSURE

Purpose: Demonstrate a mechanism which produces a constant water pressure.
