Which of these is the best conductor of electricity?

• glass rod

• copper penny

• plastic tubing

• cotton string

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

• Plastic is a good insulator

• Plastic can melt when heated

• Plastic is softer than wire

• Plastic conducts electricity

A characteristic of matter that can be observed or measured and can be changed without changing the matter itself.

• mass

Students were asked to make observations about several objects using a triple beam balance, a magnet and a container of water. The observations were recorded on the table shown. Which statement is true if students wish to sort the objects into exactly two groups?

• Magnetism can be used because not all the objects were attracted to a magnet.

• Mass can be used since all measurements are less than 25 grams.

• Density can be used because all the objects sink in water.

• Shape, color, and state of matter can be used because all of the objects are solids and have a different appearance.
