This kit introduces students to the concept of energy conversion through the study of a simple electrochemical cell connected to an electric motor. Electrochemical cells are the basis for batteries and contain metals and other chemicals with stored chemical potential energy. Students design and conduct an experiment that uses the unique Lan-Aids© Wet...

In this exceptional introduction to paper chromatography, students learn how chromatography can identify the makeup of organic and inorganic substances. Students perform experiments to compare the effects of different solvents on the separation of chlorophyll extract and dyes into their constituent components.

The wave mechanical theory of atomic structure is mathematical, abstract and often confusing to students. The model students build in this activity helps them more easily visualize and better understand aspects of the wave mechanical theory. Using specialty designed components, students assemble their own spatial 3-D models. The models demonstrate the position and number...

With this activity, students learn to predict the formula of a compound by comparing the amount of the compound produced when combining different ratios of reactant solutions. Students use a chemical analysis method to determine the ratio of each of the ions in the product substance’s composition. Knowing the ratio, students can...

Your Lab-Aids® 9 Level Conductivity Meter is well constructed. When treated with proper care and concern it will provide you with many hours of satisfactory service. The Lab-Aids® 9 Level Conductivity Meter shows the relative conductivity/resistance of liquids and solids. As the conductivity of the tested material increases, the number of glowing red...

Auditory Conductivity Indicators are a practical alternative to light sensitive LED conductivity indicators. They also provide semi-quantitative information about the materials being tested. When both probes are in contact with a solid, or immersed in a solution, and the material is a conductor, the audible tone increases in volume and intensity as conductivity increases....

This kit provides students with a hands-on experience in the principles of ionization. Using conductivity testers*, students first differentiate among strong electrolytes, weak electrolytes, and non-electrolytes. They then differentiate between strong and weak acids and strong and weak bases. This activity is designed for use by students in introductory chemistry courses and higher.

Developed for use with SEPUP's course Science and Sustainability but useful for any classroom distillation, this unique condenser uses ice water to cool and condense hot gases and therefore does not require a sink with a water supply and a drain.
