# Lesson Worksheet: Heat Conduction Science

In this worksheet, we will practice investigating and comparing materials that conduct or insulate heat and exploring different uses of these materials.

Q1:

Fill in the blank: An object that is a good insulator .

• Adoes not allow heat to pass through it
• Ballows heat to pass through it
• Cdoes not keep things warm
• Dis used to conduct heat

Q2:

Fill in the blank: Woolen clothes are used to keep the body warm in the cold. Wool is a of heat.

• Agood insulator
• Cgood conductor

Q3:

Fill in the blank: energy is a form of energy that transfers from warmer objects to cooler objects.

• AChemical
• BElectrical
• CHeat
• DNuclear

Q4:

Fill in the blank: A metal pot is a good conductor of heat because it .

• Adoes not allow heat to pass through it
• Bkeeps food warm when cooled
• Ckeeps food cold when heated
• Dallows heat to pass through it

Q5:

Below is a cross section of a window. What is the function of the air between the glass?

• AIt functions as an insulator to keep heat from passing through.
• BIt functions as a conductor to allow heat to pass through.
• CIt functions as a conductor to keep heat from passing through.
• DIt functions as an insulator to allow heat to pass through.

Q6:

Emma was doing an experiment on heat conduction. She took three rods. One rod was metal, one was plastic, and one was glass. Emma attached a button to the end of each rod with melted wax. She put the rods in a beaker of hot water.

What do you think happened to the buttons after 15 minutes?

• AThe button on the plastic rod fell off.
• BThe button on the glass rod fell off.
• CThe button on the metallic rod fell off.
• DThe buttons on all of the rods fell off.

Why?

• ABecause this material is a good conductor of heat
• BBecause this material is a poor conductor of heat
• CBecause this material is an insulator of heat

Q7:

Michael was doing an experiment to test how well different metals conduct heat. He took three rods, one made of steel, one made of copper, and one made of aluminum. He attached a button to the end of each rod with melted wax.

Michael put the rods on a stand and heated the ends opposite the buttons with a Bunsen burner. He measured the amount of time it took for the buttons to fall off each rod.

The results of his experiment are shown below.

 Material Time Steel Copper Aluminum 7 minutes 5 minutes 6 minutes

Which rod is the best conductor of heat?

• AThe aluminum rod
• BThe copper rod
• CThe steel rod
• DAll of the rods conduct heat equally well.

Q8:

Liam and Chloe are discussing heat energy.

Who is correct?

• AChloe
• BLiam
• CThey are both wrong.

Q9:

When you hold a hot drink, heat energy travels from the cup of coffee to your hand.

What happens when you hold an ice cube?

• ACold energy travels from the ice cube to your hand.
• BHeat energy travels from your hand to the ice cube.
• CHeat energy travels from the ice cube to your hand.
• DCold energy travels from your hand to the ice cube.

Q10:

A group of students are talking about which materials are good to use in the handles of cooking pots and kettles.

Who is correct?

• AEmma only
• BEmma and Mason
• CMichael and Chloe
• DMason only
• EAll of them are correct.
