Logic of Friendship1. You can be my friend if you are trustworthy and loyal
and brave.2. You can be my friend if you are trustworthy and like
baseball or ice hockey.3. You can be my friend if you like cooking or baseball or
jazz music.
Friendship Meter Procedure
1. Brainstorming2. Logic Diagram3. Wiring Diagram4. Circuit Simulation5. Circuit Construction and Testing6. Presentation7. Reflection Paper
Brainstorming Procedure
1. Identify qualities of a good friend. Brainstorm a list of things that you find important in a good friend.
2. Identify possible materials you can use for the construction of your friendship meter.– All meters will be powered by a 9-Volt battery.– Holiday lights will be provided– At least one thing related to your program area must be
incorporated into your meter– At least one thing related to your “Friendship List” must be
incorporated into your meter
Logic Diagram Procedure1. Choose at least four traits that you want to use for your
Friendship Meter. You can choose more but you must have at least four.
2. Identify each trait as either exclusive (an and statement) or not exclusive (an or statement)
3. Write questions that clearly show the relationship between the trait and whether or not that person can be a friend.
4. Draw a diagram that shows how your exclusive statements relate to the other statements.
Wiring Diagram Procedure1. Design a wiring diagram for your Friendship Meter.
Wiring diagrams are a road map or blueprint to how to build the circuit.
2. Use the following symbols to assist in your diagram:
Wire
Switch Battery
Lamp
Circuit Simulations Procedure1. Test your Friendship Meter circuit using the following
website:
2. Use your circuit simulation to identify any errors in your wiring diagram. Correct any errors.

Circuit Construction Procedure1. Construct your Friendship Meter using the materials
provided and any additional material you choose to provide.
2. Be sure to construct your Friendship Meter the way it is shown on your revised wiring diagram
3. Test your Friendship Meter to make sure the circuit works as planned
Presentation Procedure1. Test your Friendship Meter on at least four people.2. Try at least three other people’s Friendship Meters.
Reflection Paper Procedure1. Write a one to two page paper that addresses the
following:1. Your overall opinion of the project2. Whether you prefer to work with wiring diagrams, circuit
simulations, or actual circuit components. Explain your reasons.
3. A comparison between your Friendship Meter and the other meters that you tested
4. Ways to improve your Friendship Meter5. Ways to improve this project
