Circuit Wizardry

Study Guide


Coach Guide to Circuit Wizardry:

There is a supply box of materials used in the previous year available at the school. However the supplies used in training were different from those used in the event. Recommend going to Radio Shack to purchase similar practice materials to better train for the event. The event used C batteries in a battery holder with regular wire to make connections. Batteries and holders should be all you need to purchase. Recommend one set for each student.

Part I:
All required info. is already on the wiki ...see above.

Part II:
In Part II of the event the students were given "circuit cards", basically closed file folders with brads or tacks and internal connections between two brads. The students used the continuity tester to find and document the connections. The cards were difficult to work with and required a good amount of pressure on the contacts to get a connection. Recommend making similar cards for practice. See Youtube Video "Electrical Conductors and Insulators" for the second portion of this part of the event.

Part III:
There is a practice test already on the wiki...See above under "test" heading.

Lastly I cannot stress enough that this test all comes down to time, it is almost impossible to finish. Recommend at least 10 weeks to prepare for this event. Also consider loaning supplies to each student to practice building at home. In the final 1 to 2 weeks prior to the event all meetings should be practice event training - actually recreate and time the students in the event to build skill and confidence.

Additional resources:

Series and Parallel Circuits:
This video is a good introduction to DC circuits.

Series and Parallet Circuit Differences: This is a good visual video with actual parts. Students can recreate this experiment in practice, good training for building circuits in Part III of the event.

Electrical Conductors and Insulators:
This video is a great example of Part II of the Circuit Wizardry Event. The students build a continuity tester and then test the various materials for conductivity or insulation and place the items into the two catagories.

Build your own Circuits Online!:
The software used in the "Series and Parallel Circuits" Youtube video can be found at this site:
Students can construct and test their own circuits online. This is flash based so laptops and PCs only.

On iPad there are a couple free apps:
Building Serial Circuits (Lite)
Building Parallel Circuits (Lite)
The upgraded versions are only $1.99
