$100 Question from Circuits
Name the four
parts of a circuit
© LoveLearning 2014
$100 Answer from Circuits
Battery, wire, switch, light bulb
© LoveLearning 2014
$200 Question from Circuits
What is the function of a battery in a
circuit?
© LoveLearning 2014
$200 Answer from Circuits
It provides the
“push” to keep
electrons moving in the circuit
© LoveLearning 2014
$300 Question from Circuits
Explain one way to change a circuit
© LoveLearning 2014
$300 Answer from Circuits
• Adding more bulbs
• Add another battery
• Switch the wires around
© LoveLearning 2014
$400 Question from Circuits
Explain how a bulb works
© LoveLearning 2014
$400 Answer from Circuits
The filament wire is very thin, so electrons have
a hard time passing through. When electrons
do pass through, the filament becomes hot and
begins to glow

$500 Question from Circuits
In which part of a circuit is electrical energy
changed into other forms of energy?
a. The battery
b. The switch
The wire
d. The load (anything that uses current to work)
c.
