Gloves help keep your hands warm in winter because:

• They are conductors of heat.
• They are fuzzy.
• They are conductors of electrical energy.
• They are insulators.

London is collecting various equipment to be used for a science fair project. Which item should he choose to demonstrate the insulation of thermal energy and why? 

• Aluminum pie pan, because heat travels through it quickly

• Plastic knife, because it can melt easily

• Wooden log, because it can be used to start a fire

• Wool sweater, because it keeps people warm

Why are many pans made out of metal but have plastic handles?

• The metal acts as a conductor to help cook your food and the plastic acts as an insulator to protect your hand from getting burned.

• The metal and plastic are both insulators to protect your hand from getting burned.

• The metal acts as a insulator to help cook your food and the plastic acts as an conductor to protect your hand from getting burned.

• The metal and plastic are both conductors to help cook your food.

How does wearing a coat help keep you warm in the winter?

• Your coat provides heat for your body.

• Coats are always warmer than people's bodies.

• Your coat prevents the cold from entering your body.

• Your coat slows down the heat energy leaving your body.
