Snap Circuits Jr. SC-100 Electronics Discovery Kit can help introduce a young child into the world of STEM. Recommended for ages 8-15, this kit allows boys and girls to create working circuits like those in television sets, radios, and other electronic devices. The projects include a musical doorbell, a voice-controlled lamp, a sound-activated switch, and many more. The pieces (snap wires, slide switches, an alarm circuit, a music- integrated circuit, and speaker) are color-coded for easy identification, and they snap together on a plastic grid. There is no soldering required. The Snap Circuits Jr. SC-100 doesn’t have a lot of little pieces which can get lost, and it’s safe for young children. Even a bright 5-year old can use this toy to learn problem solving: how to put things together, and make them work. The variety of projects can keep him busy for hours.



The company’s claim that this toy teaches “all about electronics” is a stretch. It contains only one simple resistor, no capacitors, and no transistors.  The only IC is in a sealed, opaque box, where kids can’t see it, and there is no description of what other circuitry might be inside. Of the “100 projects,” many are similar to each other. A child may complete all the projects in a few weeks, and then lose interest – although there is an upgraded version available with more projects.

One of the biggest drawbacks of this item is the lack of  a “why.” Why does the unit light up when the wires are connected?  Why doesn’t the sound play if different pieces are used? The consumer is told vaguely what a circuit is supposed to do, and there is a picture of it, but there is no explanation of why it should work as planned, or what each component does.

This toy may be compared to electronic Legos. Left to himself, a child can figure out how to connect the pieces without understanding electricity. This may not make him more creative.


The Snap Circuits Jr. SC-100 Electronics Discovery Kit has won an award for Dr. Toy’s Best Children’s Products. It’s fun, colorful, and educational for small children, although older ones may want more.
