Course & Activity Guide Description
Antioch Community High School Course & Activity Guide provides the following course description:
Elective 9-12, 1 semester 1/2 credit
This course will study theories related to the field of electronics and complete lab activities to reinforce these theories. Students will wire residential light circuits, solder connections, use computer simulation, make wire connections, and build a 12 volt battery charger*. This course is recommended for students pursuing careers in the construction trades, service industries, automotive service, a technical career, or an engineering degree.
*Currently, students are not building a battery charger. Comparable activities are done.

Activities
Students in Electronics 1 class will complete many hands-on activities. Activities include:
Quiz board
A project made from a cardboard 14-inch cake circle, wire, brass paper fasteners, drinking straws, LED, and batteries. Students print one column of electronics vocabulary and one column of vocabulary definitions onto a cake circle. Each vocabulary word and definition has a brass fastener next to it. Students make electrical probes by wiring drinking straws with wire and brass fasteners. Students quiz themselves by placing one probe onto the brass fastener next to a vocabulary word and placing the other probe onto the correct corresponding definition. If students choose the correct definition, a complete circuit will be made, thus lighting the LED.
DC permanent magnet motor
A project made from scrap wood 2 x 4, angle irons, wooden dowel rod, nails, screws, wire, and a magnet. The angle iron is used as an upright to support the armature of the motor. Nails are inserted into either end of the dowel rod. The nails allow the dowel rod to rotate freely within the top hole of the angle iron. On the dowel rod is a bundle of wire creating the armature. A commutator is assembled on one end of the dowel. A magnet is placed below the armature. Power is applied and after some adjustment the motor will run.
Buzzer
A project made from scrap wood 2 x 4, wire, sheet metal strips, nails, screws, and tape. A large framing nail is hammered into a scrap piece of 2 x 4. Thin gauge wire is wrapped around the framing nail. A sheet metal strip is bent into a 'Z' shape. The sheet metal is affixed to the 2 x 4 so that the top of the strip is 1/8-inch above the head of the nail. Thicker wire should touch the top of the sheet metal strip. After some adjustment, the sheet metal will produce a buzzing sound when voltage is applied.
Various soldering kits from Chaney Electronics
Different soldering kits bought from www.chaneyelectronics.com. Kits only sold to educators.
Wiring different types of switches & relays
Using alligator-clips attached to copper wire, students will build low voltage circuits that contain relays, momentary switches, single pole/single throw switches, single pole/double throw switches, double pole/single throw, and double pole/double throw switches. Students learn to control everyday electrical loads (lamp, motor, doorbell, street light) with different switches and relays.
Wiring LEDs and lamps (series & parallel circuits)
Using a breadboard, a low voltage power supply, LEDs, and lamps, students will wire series circuits, parallel circuits, and series/parallel circuits. Students will turn on/off the circuits with various switches. Students will observe and record the brightness of the LEDs and lamps along branches of the circuits.
Assembling different AC residential power circuits
Approximately a month-long activity in which students will work with romex wiring, various wire strippers & cutters, wire nuts, junction boxes, lamp sockets, various switches, and various outlets. On a simulation board, students will wire many circuits common to residential AC wiring. Students will learn how to control outlets and lamp sockets with switches. Students will also learn the importance of protecting circuits with fuses and circuit breakers.
Identify and measuring values of various resisters
Using a volt-ohm-meter (VOM), students will measure and record the value (Ohm) of several resisters. Then, students will record each resister's printed value by reading the resister's color code. Next, students will calculate the difference between the measured and printed values. This difference is the resister's tolerance.
Drawing Schematics
Using a chart of symbols from the instructor, students will draw schematics given a particular scenario. Students will draw the schematics clearly and follow proper electrical conventions. Students will draw schematics for many common circuits including a doorbell, buzzer, and street light.
Wiring circuits from provided schematics
Given a schematic, students will choose the correct electrical parts and build a working circuit. The circuit must be wired safely and must work as prescribed. Students will build many circuits with motors, LEDs, lamps, switches, relays, and various power supplies.
