5th grade science heat transfer review

Kayla has a wooden rod, a steel rod, and a glass rod. How could she compare the materials to find out which transfers thermal energy BEST?

• Submerge each rod in ice water to find out which loses the most heat.

• Place the three rods in a freezer to find out which becomes the coldest.

• Place one end of each rod in very hot water to find out which becomes hot the fastest.

• Place the rods on a table in a warm room and find out which feels warmest after a period of time.
