This guide is not intended to be a copy of the test. Use the information listed below, as
well as any graphic organizers, workbook pages, and review questions to help you
prepare for the test. You should also use the chapter review to help you study.
Multiple-Choice Format
1. What causes static electricity? when positive and negative charges are no
longer in balance
2. What kind of particles form at the bottom of a storm cloud? negative
particles
3. Be able to identify the charge that attracts and repels a positively charged
object. negative attracts positive; positive repels positive
4. What would be a good conductor for a closed circuit? copper
5. Be able to identify how a doorbell works. electromagnets convert electric
energy to magnetic energy to mechanical energy
6. Be able to identify the material that conducts electric current poorly. an
insulator
7. What happens if a bulb burns out in a series circuit? the other lights will go
out
8. How can the strength of an electromagnet be increased? by using more
turns in the metal coil
9. Be familiar with what Michael Faraday did with his discovery. he shared it
with other scientists
10. Why does a compass needle point in a north-south direction? the needle
reacts to Earth’s magnetic poles
11. How do you create electrical energy? by spinning a coiled wire around a
magnet
12. Where is a magnetic field the strongest? at both poles
Short Answer Format
Be able to answer the following in complete sentences.
 Explain what happens to a magnet’s poles if a magnet is broken into two
parts. What poles will seek each other on the two magnet parts?
If a magnet is broken into two parts, each part will still have its own north-seeking
and south-seeking poles. The north-seeking pole of one part will attract the southseeking pole and repel the north-seeking pole of the other part.
 Do modern homes use electricity that is arranged in series or in parallel
circuits? Explain.
Modern homes use electricity that is arranged in a parallel circuit. Parallel circuits
can handle appliances that use different amounts of electric current. Also, other
appliances on the circuit continue to run if one stops working.
