Circuits

Circuit Assignment Area of Interaction: Environments

=== Significant Concepts: Basic circuits ===

=== Unit Question: How have circuits impacted our environments? ===  Define the following:  1. Voltage: An electromotive force or potential difference expressed in volts  2. Current: A flow of electricity which results from the ordered directional movement of electrically charged particles

 3. Resistance: The electrical resistance of an object is a measure of its opposition to the passage of a steady electric current

 4. Circuit: A complete and closed path around which a circulating electric current can flow   5. Transistors: A semiconductor device with three connections, capable of amplification in addition to rectification <span style="display: block; font-family: arial,helvetica,sans-serif; font-size: 13px;"> <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;"> 6. LEDs: A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices, and are increasingly used for lighting.

Capacitor: A device used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator <span style="color: #0000ff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;"> 8. Resistor: A device having a designed resistance to the passage of an electric current <span style="color: #0000ff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;"> 9. Switch: A device for making and breaking the connection in an electric circuit <span style="color: #0000ff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;"> 10. Digital Electronics: Digital electronics represent signals by discrete bands of analog levels, rather than by a continuous range. All levels within a band represent the same signal state <span style="color: #0000ff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;"> 11. Integrated Circuit: An electronic circuit formed on a small piece of semiconducting material, performing the same function as a larger circuit made from discrete components <span style="color: #0000ff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;"> 12. Binary Code: A coding system using the binary digits 0 and 1 to represent a letter, digit, or other character in a computer or other electronic device <span style="display: block; font-family: arial,helvetica,sans-serif; font-size: 13px;">

<span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Spend two day creating snap circuits. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">13. How many circuits did you make? (You need to make at least 6 circuits)  <span style="display: block; font-family: arial,helvetica,sans-serif; font-size: 13px;"><span style="background-color: #ffffff; color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">We made 6.5 circuits <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;"> 14. What was your favorite circuit? <span style="color: #0000ff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">The alarm circui was our favorite. 15. Did you like the snap circuits? Explain why: <span style="color: #0000ff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">We felt like they were too simple and therefore didn't enjoy them that much. <span style="display: block; font-family: arial,helvetica,sans-serif; font-size: 13px;"> <span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Spend 4 days making your bug circuit. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">16. Did your circuit work? <span style="color: #0000ff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">No 17. Did you like making the bug circuit? Explain why: It was cool, except we lost all of those pieces, so it made it difficult to finish it. 18. How have circuits impacted our environment? <span style="color: #0000ff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Circuits have changed the way we accomplish tasks, and therefore have changed the technological environment. <span style="display: block; font-family: arial,helvetica,sans-serif; font-size: 13px;">

<span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">How you will be graded: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Answering Questions: +25 Snap Circuits: +30 Bug Circuit: +30 Total: 85
