Whether at home on in the classroom, these kits are ideal. They are low-cost, reliable, hands-on, reusable, and durable.  

Comes with all electronic parts.  In addition, all you need a Solderless Circuit Board (Kit #MC1-00) and a 9V battery to do any of the experiments.

Learn Basic Science Electronics - Reusable - Durable - Fun - Easy - Real Components - For Future Engineers and Techs - for Maker projects - for Science Fairs 


Understanding Science Electronics is vital!  Your future depends on it!  Many of life's decisions are based on technology, i.e.  what cell phone should you buy, what TV should you buy, should you buy and EV, should you install Solar power,  what about Wind Power, or how much power are you using?  What is an Ohm, and what is a Watt?  

** Mr Circuit Science ** Experiment Kit #MC1-07 "How An SCR (Silicon Control Rectifier) Works"


It includes Online Video Lesson and online Quiz.

All the parts are provided and diagrams, instructions and videos. 


When you order this kit, you will receive all the necessary electronic components to do the experiments,  printed instructions, and a link to view the online video presentations where an electronics instructor takes you through the lessons step by step.

The purpose of these learning kits is to teach you the basics of science electronics technology by building electronic circuits with real electronic components.

This hands-on experience will give an individual valuable skills for them to use in today’s world of technology.
