The United Scientific CCK001 Create-A-Circuit Kit includes components for building a series circuit: a knife switch, two lamp holders, two miniature light bulbs that fit the lamp holders, four connector cords, and a D-cell battery holder (battery sold separately). The kit comes with an activity guide outlining different demonstrations of a series circuit. In a series circuit, components are attached in one direct line, and any break in the line causes the entire circuit to fail.

Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.

United Scientific Supplies manufactures laboratory supplies and science education products. The company, founded in 1992, is headquartered in Waukegan, IL.
