— Career & Technical Ed. teacher · AZFrequently asked
Answers for teachers, parents, and makers.
What grade levels is this lab for?
Mr Circuit labs work well for grades 6 through college. Middle schoolers use them as a first introduction to circuits. High school CTE and career-tech programs use them as the foundation for HVAC, automotive, robotics, and engineering pathways.
Does this lab require soldering or any power tools?
No. Every circuit is built on a solderless breadboard using pre-stripped jumper wires. The only power source is a 9-volt battery. Safe for classrooms, safe for students, and fully reusable.
How long does each lesson take?
Most lessons fit inside a standard 45–55 minute class period. The first few lessons are shorter (component introductions), and the later circuit builds may span two periods depending on pacing.
Can I order with a school purchase order?
Yes — public schools, districts, and nonprofits can order using a purchase order. Email us and we'll send a W-9 and a formal quote (usually the same day).
Is the lab reusable for next year's class?
Yes — that's the whole point. Components go back in the tray, and the lab resets for the next student. Replacement parts are available individually if something gets lost.
What's the difference between this lab and MC1-SET?
This lab is a single kit — one student, one breadboard. MC1-SET is the classroom bundle with 32 reusable experiment kits and full digital platform access. Most teachers ordering for a full class go straight to MC1-SET.
