A student helped his father prepare soup for dinner. His father asked him to use a wooden spoon to stir the soup as it heated.

Why would the student's father ask him to use a wooden spoon?

• The wooden spoon is able to float in the soup

• the wooden spoon is able to sink in the soup

• the wooden spoon is a good conductor of thermal energy

• The wooden spoon is a good insulator of thermal energy

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.

Erosion is one of the processes involved in the formation of sedimentary rock. Which of these best describes the process of erosion?

• Rocks are broken into smaller pieces that remain in the same location.
• Pressure compacts layers of sediment and turns them into rock.
• Pieces of rock or soil are carried from one place to another.
• Sediment grains fall to the bottom of a lake to form sedimentary layers.
