(Thermal Energy) DOL - 5.6A

Tom notices that his mom uses different spoons when cooking. Some have wooden handles; others have metal handles.

Why might wooden handles be better to use on cooking spoons?

• Wood is lighter than metal.

• Wood is not a good conductor of heat.

• Wood is easier to clean.

• Wood is a good conductor of heat.

A student is designing a container to keep frozen foods cold. Which material is the BEST option to use when building the container?

• Glass is an insulator that will keep the food cold.

• A newspaper is an insulator that will keep the food cold.

• Aluminum is an insulator that will keep the food cold.

• Wood is a conductor that will keep the food cold.

A teacher sets up an experiment using five jars like the ones below. The teacher

keeps one jar unwrapped and the other four wrapped with equal thicknesses of

different materials.

The jars are filled with equal amounts of water at a temperature of

92°C. Students observe and record the water temperature in each jar after 10

minutes.

The results are shown in the table below.

Explain why the temperature of the water in some jars was higher than in others after

10 minutes. Use evidence from the experiment to support your answer.
