Exploring Conductivity of Solutions

National Standards for Grades 7-10

Students build a simple conductivity tester and use it to evaluate the conductivity of various chemicals and solutions. They evaluate the chemistry of conductivity through ionic and non-ionic substances, acidic and basic substances, solid and liquid metallic ions, and substances with different polarities. Extension activities have students exploring practical questions such as how electricity can electrocute through water, what properties make a good sports drink, and how electroplating occurs. Allow two hours for experimentation.

Single kit is designed for 1-4 students. Class kit is designed for 24 students working in groups of four. Goggles are required; one pair is included in the single kit. No goggles are included with the Class kit.
