Look at picture #2-- Why will the lightbulb in circuit B NOT light up?
the light bulb is out of energy
the battery is out of energy
One wire is not connected and the circuit is open
one wire is not connected and the circuit is closed
Look at picture #3-- Which of the following best explains the purpose of using a metal paper clip
the paper clip is a conductor and doesn't allow the flow of electricity

the paper clip is an insulator and allows the flow of electricity
A circuit is the path followed by an electric current. A circuit is made up of three parts. The first part is energy source, such as a battery or generator. The second part is an energy receiver, such as a motor or lightbulb. The third part is a connection, such as a wire or cable that carried energy from the source to the receiver. In addition, there are two basic types of circuits: series and parallel. According to the passage, what is the second part of a circuit?
electric current
energy source
engird receiver
a generator
Look at picture #6-- which of the following circuits will produce light?
A
B
C
D
Look at picture #7-- A flashlight is a system of parts that work together. What part of a flashlight provides energy?
battery
bulb
spring
switch
Which statement BEST explains the reason the electrical wires are made of copper?
copper is strong
copper is flexible
copper is a conductor
copper is an insulator
Look at #10-- Students made an electromagnet by wrapping a wire in loops around an iron nail and attaching the wire to a battery. The students conducted a test to learn how the number of wire loops affected the number of paper clips held by the electromagnets. The table show the results of the test. Based on the information in the table, which of the following is the best conclusion?
adding more wire loops makes an electromagnet weaker
adding more wire loops make an electromagnet stronger
adding more wire loops make an electromagnet use less electricity
adding more wire loops makes an electromagnet use more electricity
Look at picture #9-- What will happen if you touch a metal paperclip to the nail?
the wires will melt
the battery will spark
the nail will give you a shock
the paperclip will stick to the nail
