This easily-constructed battery can be built using two chemical solutions and two metal electrodes in a small jar. It produces a constant source of 1.5 V and can be used to power a flashlight. Using the materials include . . .

Appropriate for Grades 6-12 -- Use the Copper Voltameter for demonstrating and conducting electrolysis experiments. -- The Copper Voltameter has three thick copper plates wth brass terminals suspended form a bakelite cov . . .

This Conductivity of Solutions Apparatus comes with one copper and one carbon electrode, binding posts, and a glass jar. It requires a 3V battery or DC power supply and takes a miniature 3.2V bulb. . . .

Flat electrodes especially designed to fit the U-tube of the Hoffman Electrolysis Apparatus. The platinum lead wires are sealed in glass tubes that are inserted into No. 1 rubber stoppers. . . .

The Apparatus Support consists of the heavy metal tripod base, mounting post, and metal support panel for the glass components. -- The support panel is specially designed with binding posts in the base and double clamps . . .

Glass parts include the graduated U-tube with stopcocks and the glass thistle tube. . . .

A low cost electrolysis kit designed to replace the large, fragile and expensive models that have been used in schools for years. Using this small-scale model you can afford to perform many different experiments at the s . . .

This complete apparatus will demonstrate the decomposition of water (separation of oxygen and hydrogen). -- Each of the glass tubes has stopcocks and is graduated to give precise measurements. The tubes are mounted on a . . .

Use this inquiry-based lab to demonstrate the empirical formula for water, gas laws, electrochemistry, cathode anode identification, acid base indicators, ideal gas equation, and calculation of Avogadros number. -- Inclu . . .

Demonstrate the transformation of energy from one form to another with this dramatic activity. -- In this experiment, the potential difference (voltage) between two metals and the number of electrons (the current) formed . . .

Good question! In this lab designed by teacher David Galliher, students make a simulated space shuttle from a plastic bottle. Students observe how far the rocket travels and figure how to get the greatest thrust. -- Incl . . .

This truly innovative lab allows students to perform a series of fun and fascinating activities whose dramatic results will lead them to a better understand of the principles behind the concept of ionization. -- They lea . . .

With this kit students study the principles of conductors and insulators; study and develop the principles of electrolytes and non-electrolytes using acids, bases, salts, alcohols, and hydrocarbons; test a variety of com . . .

Observe the effects of electric currents on liquids with this apparatus that features graduated arms with stopcocks at the top. In addition, the reservoir filling tube and buret arms are connected by vinyl tubing to reli . . .

Increased functionality equips this device for accurate and precise use in chemistry experiments. The apparatus features front spring clips, which allow you to easily remove the test tubes while they remain submerged. Th . . .
