If you put a metal spoon and a wooden spoon into a pot of boiling water, one will become too hot to touch. Why? 

• Metals conduct heat better than wood.
• Wood conducts heat better than metals.
• Metals pull in heat because heat is attracted to metals.
• Wood isn’t as strong as metals.

On a hot day, the upstairs rooms in a house are usually hotter than the downstairs rooms. Why?

• Cool air is less dense than hot air.
• Warm air rises and cool air sinks.
• The roof insulation warms the air.
• Heat rises.

When you hold a metal coat hanger in a camp fire to roast a marshmallow, the coat hanger might become too hot to hold. Why might the coat hanger get too hot?

• The heat radiates along the coat hanger.
• The heat builds up near the flame until it can’t hold it anymore and then moves     along the coat hanger.
• Metal atoms vibrate with more energy when they get hot, and they collide with   atoms near them, which causes the neighboring atoms to vibrate.
• Since metals melt in fire, they react strongly to fire and get hot easily.
