Conductors and Insulators

The following are conductors EXCEPT-

• 
• 
• 
• 

Conductors are materials that...

• Allow heat to pass through
• Stop heat from passing through
• Allow cold to pass through
• Stop cold from passing through

What is a insulator?

• a material that slows the transfer of heat
• a material that transfers heat easily
• a material that is fluffy
• a material that is temperature controlled

A material that prevents heat or an electric current from flowing

• Conductor

• Insulator

• Magnetism

• Electric Circuit

What is NOT an example of an insulator in the kitchen?

• an oven mitt
• pots and pans
• wooden spoons
• a plastic measuring cup

The electrical wires in many homes are made of copper and covered with plastic. Why are copper and plastic good choices for electrical wires?

• Copper is a conductor of electricity, and plastic is an insulator of electricity.

• Copper is an insulator of electricity, and plastic is a conductor of electricity.

• Copper is a conductor of electricity, and plastic is an insulator of heat.

• Copper is an insulator of electricity, and plastic is a conductor of heat.

This girl is wearing pink wool earmuffs to keep her ears warm in the snowy weather. Differentiate between conductors and insulators. How does the wool affect heat transfer? (wool is a type of fabric)

• The wool is a conductor that transfers heat from her ears to the wool earmuffs.

• The wool is an insulator that provides heat to keep the girl's ears warm.

• The wool is a conductor that transfers heat from the girl's earmuffs to her ears.

• The wool is an insulator that keep the girl's ears from loosing heat.

A student is having a problem getting a light bulb to light up in an electrical circuit. They notice there is a gap in the wiring but there is not enough wire to complete the circuit. What could the student do to fix the problem?

• put a rubber handle in the gap

• use a piece of of nylon rope to attached the wires together

• change the battery or the light bulb

• attach a paperclip to the wires in between the gap

Which of the following is a group of items that can be used to conduct electricity?

• paper clip, nail and penny

• paperclip, nail and cardboard

• rubber-band, eraser, and cotton ball

• rubbe- band, paperclip and nail

Which is TRUE about an insulator?

• It can be a good conductor.

• It allows heat to pass through easily.

• It slows energy transfer.

• It provides heat to keep materials warm.
