Everything needed to get started with the popular BBC micro:bit microprocessor.

Relate Motion to Sound

Spectrum Tubes demonstrate the wave properties of different gases.

A set of four borosilicate glass tubes of different shapes connected together to illustrate that liquids will stand at the same level.

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

This safe spectrum power supply features encased spectrum tubes.

Every classroom that wants to investigate spectroscopy needs a good-quality spectrum tube and power supply.

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

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

100 feet of extra tubing for TeacherGeek projects.

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

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

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