"tube coolers"

The Speed of a Bubble Set connects the mathematical concept of slope to the physical science concept of velocity.

100 feet of extra tubing for TeacherGeek projects.

Study Wavelengths and Energy All With One Device

This apparatus is used to Verifying the Boyle’s law when air is decompressed and compressed. A horizontally mounted acrylic tube having a graduated scale (0- 300cm3) along one side. A gas tap closes the tube. Pressure gauge is present next to gas tap. By changing the position of rubber stopper, the effective length of the tube can be selected. The scale measures volume and pressure by means of pressure gauze. Boyle’s law is investigated by changing position of the stopper.

With the magnet is on the outside, it's easy to see the science behind these eddy tubes.

Wide range of cubes for density experiments.

Both versions of these economy tuning fork sets come with a mallet designed for one hard and one soft end for use with all frequencies of forks.

Specific Gravity Cubes with Hooks.

These long-lasting aluminum tuning forks have a full sound.

How Does Mass Affect Transverse Waves?

This aluminum tuning fork has sliding weights on each tine.

Even frequencies make harmonic relationships clear and calculations easier.

Designed for Physics and Physical Science experimentation.

Both of these sets come with a roll-up style canvas storage pouch and a solid rubber activator.

These Physical Pitch Sets are highly accurate.

Long, pure sounding aluminum tuning forks.
