The difference in electric potential energy per charge between two points in a circuit. (page 294)
What is voltage?
100
Any disturbance that transfers energy from one place to another. (page 303)
What is a wave?
100
This kind of signal was combinations of dots and dashes and was used to communicate via the telegraph. (________ code)
What is Morse Code?

Dominic is building a circuit to send out Morse code signals. He uses a light bulb turning on and off to show the code. He connects the light bulb to the battery with copper wires. He also connects a switch he can use to tap out the code. Should the circuit be in series or in parallel for Dominic’s project to work?
Choose series or parallel
What is series?

One of Mrs. Campbell's grandkids.
What is Clem, Townes or Owen?
200
How difficult it is for current to flow through an object. (p. 295)
What is resistance?
200
This type of wave results from the vibration of a medium, such as water. (page 303)
What is mechanical wave?
200
This type of signal (choose analog or digital) allows for a continuous record of some kind of action (high resolution so they take a lot of space). Page 314
What is analog?
200
Kavi built a circuit with a 180-volt battery and a 1000-ohm resistor. He wants to build another circuit with the same resistor but twice the current. What would the voltage need to be on the new battery?
Choose 360 OR 270 volts
What is 360?

What is Socastee High School?
300
voltage divided by current equals this (page 296)
What is resistance?
300
This type of wave has a motion that doesn't go up and down, it goes sideways. (page 304)
What is a longitudinal wave?
300
This type of signal allows for a record of numerical values over time intervals, we use this most often now (page 314)
What is digital signals?
300
Ohm's law can be used to understand the relationship between resistance, voltage and current. If voltage increases, the current increases. This is what type of relationship?
(Choose independent or proportional)
What is proportional relationship?
300
The name of our security officer.
Who is Officer Tores?
400
This type of circuit has all parts connected on one long path
(Choose series circuit or parallel circuit)
What is series circuit?
400
This measures the distance between the resting place of a wave and it's crest or trough (it shows the height) (page 305)
What is Amplitude?
400
This is a bunch of 0's and 1's that make up bits and bytes. (page 316)
What is binary signals?

Islay records and mixes his own music. He plays it, records it on a computer and adds layers with different instruments. Then he uploads it to Youtube.
What is both analog and digital?
400
The name of our librarian.
Who is Mrs. Moore?
500
This type of circuit is wired so that if one device breaks, the others will work.
(Choose either series circuit or parallel circuit)
What is parallel circuit?
500
The top and bottom of waves are called these two terms (must have both). Page 305
What is Crest and trough?
500
These are small uniform shapes that are combined to make a picture. (page 318)
What are pixels?

Elena is using a computer program to make a transverse wave. Elena wants to make a wave that carries less energy than the wave she started with by changing one variable. How could she change her model?
a.) increase distance between compressions rarefactions
b.) increase distance between crests and troughs
What is B, increase distance between crests and troughs?
