What is an Insulator?

• A material That does not let heat move through it easily.

• Materials that let heat move through it easily.

When serving the Chocolate, Mr. Daniels observed that the pan covered in cloth was warmer than the pan covered in Aluminum. Which statement explains why the pan wrapped in Cloth was warmer?

• A. The Cloth was an insulator, slowing the flow of heat energy.

• B. The Aluminum was an insulator, slowing the flow of heat energy.

• C. The Cloth was a conductor, slowing the flow of heat energy.

• D. The Aluminum was a conductor, slowing the flow of heat energy.

What instrument do we use to measure Temperature?

• Tape measure

• Graduated cylinder

• Ruler

• Thermometer

Mr. Daniels was stirring a pot of soup cooking on the stove with a cold spoon. The spoon was left in the pot of soup as He finished making the rest of lunch. What did He notice about the temperature of the spoon after it rested in the soup?

• A. The soup was hotter because it was left in the soup.

• B. The soup was colder because it was left in the soup.

• C. The spoon was colder because it was left in the soup.

• D. The spoon was hotter because it was left in the soup.

4. Mr.Daniels was working in the yard on a sunny day. He left some of the yard tools outside in the hot sun while working. Which item would feel hottest to the touch after being left outside in the sun?

• A. a plastic Spoon

• B. a wooden Stick

• C. a metal Plate

• D. a rubber Duck

5. Mr. Daniels wears Fur Jacket in the winter because fur keeps Arms warmer than other Jackets. Which statement best explains why Fur jackets keep feet warmer when it is cold outside?

• A. Fur is an insulator that prevents as much heat from flowing away from His arms.

• B. Fur is a conductor that prevents as much heat from flowing away from Jenna’s feet.

• C. Fur is a conductor that provides heat energy to keep Jenna’s Arms warm.

• D. Fur is an insulator that provides heat energy to keep His Arms warm.

Mr. Daniels was eating a frozen popsicle after the baseball game. It was a warm and sunny day. He tried eating the popsicle quickly, but the popsicle was melting too fast. Which statement best explains why the popsicle was melting?

• A. Heat energy from the warm air was flowing into the cold popsicle.

• B. Heat energy from the cold popsicle was using up the heat energy in the warm air.

• C. Heat energy from the cold popsicle was flowing into the warm air.

• D. Heat energy from the warm air was using up the heat energy in the cold popsicle.

What is a conductor?

• A material that does not let heat travel through them easily.

• A material that let heat travel through them easily.

Mr. Daniels was shopping for new pans for the kitchen. All the pans in the store were made of similar materials. Mr.Daniels saw pans made of steel, copper, aluminum, and cast iron. Which statement explains why the pans Mr. Daniels saw were all made of different types of metal?

• A. Metal is an insulator that would prevent as much heat energy from burning the food in the pan.

• B. Metal is a conductor that would prevent as much heat energy from burning the food in the pan.

• C. Metal is a conductor that would help the heat energy from the stove flow into the food in the pan.

• D. Metal is an insulator that would help the heat energy from the stove flow into the food in the pan.

Mr. Daniels wanted to track the exact temperature changes of the two pans of Chocolate. What should HE do in order to collect the most accurate data possible?

• A. Use a scale to record the mass of the brownies in order to measure the heat energy given off.

• B. Observe the changes in the color and smell of the Choclate as they cool off.

• C. Use a thermometer to record the temperature of the Chocolate every 30 minutes.

• D. Place a hand on the Chocolate every 30 minutes to feel the change in temperature.
