Are you looking for a way to learn, study, or teach Science and Electronics Technology?  

Then this Mr Circuit series 1 hands-on Science Experiment Kits are perfect for you.  

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

It includes Video Lesson and online Quiz.

Note: (Battery and Solderless Circuit Board not included. You just need one Solderless Circuit Board (Kit #MC1-00) and a 9-volt battery to be able to do any of the Mr Circuit Science Experiment Kits.)


Understanding of Science and 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?  

It includes online Video Lesson and online Quiz.

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


When you order these ** Mr Circuit Science ** Experiment hands-on Kits, you will receive all parts to do the experiments, a printed booklet with instructions, and a link to view the online video presentation where an instructor takes you through step by step.

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