Some students test a plastic spoon as a connector in an electrical circuit. Electricity does not flow in the circuit. Plastic is most likely... A. a load. B. an energy source C. a conductor D. an insulator
D. an insulator
Light always travels in a _______ line until it _______
Straight line until it strikes an object
Is the container storing chemical energy to be converted into electrical energy. ( A power source)
Battery
What type of energy is contained in a battery?
Chemical energy
How many paths does a series circuit have?
1
Which material will best conduct electricity? A. plastic B. rubber C. wood D. silver
D. silver
What is the difference between absorption and transmission of light?
Absorb- light gets stuck in an object ( taken in)
Transmit- Light goes through an object/ medium ( pass through)
A device for making and breaking the connection in an electric circuit.
A switch
Which device can be added to an electrical circuit to convert electrical energy into mechanical energy? A. a switch B. a lightbulb C. a fan D. a speaker
C. a fan
Do you think Christmas Lights are an example of a series circuit or a parallel circuit? Why do you think that?
They are an example of a series circuit because if one of the bulbs burns out the entire strand will not light up.
If you connect the wires of an electric circuit to a piece of jewelry why would the lightbulb in the circuit still turn on?
Because the jewelry is made of metal. Metals can conduct electricity.
Mirrors, shiny surfaces, metals, smooth surfaces, calm water are surfaces that _____ light
Reflect
Explain how a switch works in an electrical circuit.
When the switch is closed, electricity can flow.
When the switch is open electricity cannot flow.
If an electrical circuit has a bell and a battery for an energy source what energy conversions will occur?
chemical energy --> electrical energy --> sound energy
What happens to the series circuit when the wires are not connected, or the switch is open?
The circuit will not work
Mrs. Johnson wants to make an electric circuit but she is fresh out of copper wire. What are 3 other household items that she could use in place of wire to carry the electricity.
silverware, keys, aluminum foil, jewelry
any metal
Prisms. lens, rainbows are all examples of
Refraction
Name all 5 types of energy, what they mean, and an example of each.
MELTS
Mechanical- movement- fan
Electrical- plug in- phone charger
Light- see- Lamp
Thermal- Heat- fire
Sound- hear- Crazy students
If one path in a parallel circuit is interrupted, could the circuit still work? why or why not?
Yes it could still work.
Other paths could be a complete path to the power source
Why do electricians use wire that is coated in plastic when they are making new circuits?
This is because the wire can be dangerous to handle and can shock humans if they handle it when the circuit is on. The plastic coating helps to protect the electricians and us!
What is ARRT?
Reflection
Refraction
Transmit
