The Mr. Circuit III - The Laws of Direct Current Experiment Guide acts as a lab log as the student completes laboratory excersizes that implement the principles learned. Each experiment lists objectives, equipment and procedures while leaving room for the students to record their observations and conclusions. This lab includes the Experiment Guide, parts and equipment needed to explore circuit theory "hands-on". This lab comes with the multimeter and does not require soldering after the first use. Upon first using the lab, a power supply kit is included so that your students may build a power supply to power the labs. Soldering is required for the power supply kit.
