The light goes on — an aha moment!
In this SCFG activity, the girls are learning that salt water is a good conductor of electricity. They are making a circuit with wires, salt water and a lightbulb. When salt (NaCl) is put in water, it readily dissolves into Na+ ions and Cl- ions that float through water. These ions can carry a charge and conduct electricity.
The girls were skeptical, but by doing this hands-on experiment, girls like Chole, pictured with mentor, Amanda, learned that electricity canpass through water, and were thrilled when the lightbulb popped on!
