"tbe buffer"

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

Boomwackers are brighly colored plastic tubes tuned by length to musical notes.

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.

Investigate the relationship between the speed of a fluid and its pressure

This safe spectrum power supply features encased spectrum tubes.

The Student Coin and Feather Tube shows the two items in a vacuum, falling at the same rate.

Used to investigate wavelength in air.

100 feet of extra tubing for TeacherGeek projects.

With the Resonance Apparatus, students investigate the effect of frequency on wavelength.
