Anemometer (1000)
Classic design demonstrates the operating principle of cup anemometers; cup rotation reflects changes in air velocity. Since this extra sensitive model responds to wind velocities as low as 2 mph, a standard electric fan may be used as the wind source.

Projection Air Table (101)
Use this miniature air table with any suitable air source to demonstrate the random movement of molecules. Made of clear acrylic this unit can be set on an overhead projector and projected so everyone in the room can observe the movement. The molecules are colored disks with mounted magnets in each. These magnets cause each disk to repel it's neighbor and thus create an almost continuous motion.

Loop-the-Loop Track (1204)
The apparatus is used to demonstrate the transformation of potential energy into kinetic energy in a fun and interesting way. Challenge your students to calculate the minimum height that the steel ball can be rolled down the track and still have it complete the loop without breaking contact with the track. The unit measures 420mm x 100mm x 430mm.

Second Law of Motion (1476)
This is a cast iron spring driven projectile apparatus. It demonstrates that a horizontally projected ball and vertically dropped ball land at the same time. The spring device can propel ball to 48" from its starting point. A detachable rod for clamping to a table or stand.

Archimedes Principle Apparatus, Plastic (1506)
This new model has a much large capacity (100ml) than the traditional aluminum model (22ml) for higher accuracy and easier operation. In additional, both the cylinder and the cup have marked divisions which allow the students to repeat the experiment with different volumes. Made of white nylon. This unit is used with a 200g spring scale, an overflow can and a beaker.

Ballistic Pendulum Apparatus (1600-4)
Unit uses a nylon pendulum with a tapered rubber insert. Both pendulum and base have leveling screws. The spring loaded gun has a self locking trigger and a rubber bumper to prevent damage on impact. The scale is marked in degrees and is registered by a counter weighted needle that remains in place at the height of the arc.

Cavendish Balance (1600-5)
This classic instrument is used to measure the value of G (gravitational constant) the same way Sir Henry Cavendish did in 1789. Consists of a pair of small lead balls mounted on a "T" member suspended with a thin wire and a pair of large lead balls. Oil damping is provided for faster results. Requires a laser ( not included )

Foucault Pendulum (1600-8)
How can you prove that the earth is rotating? Well this unit will help and it allows students and observers to witness an experiment developed by Jean Foucault in the 19th century that was monumental in developing our knowledge of our own planet and solar system. A heavy chrome ball attached to a 1 meter long wire is placed in motion by giving it a slight swing. The large circular protractor below allows you to track the sphere as the earth rotates beneath it. This item stands 5' tall and houses a electromagnetic in the base to keep the pendulum swinging by compensating for frictional and gravitational forces. Housed in a steel cabinet with glass walls and an internal light source for easy 360 degree viewing.
