Science Benchmark Review Part 1

What force slows down objects that are in motion?

• Friction

• Fiction

• Fact

• Sludge

Two wires carrying electricity can create a spark if they come too close together. This spark can start a fire. Wires carrying electricity are usuallly covered  with plastic to keep them from starting a fire. Why does the plastic keep electricity from starting a fire?

• Plastic is a good insulator.
• Plastic can melt when heated.
• Plastic is softer than wire.
• Plastic conducts electricity.
