Question 4

Students investigated how different animal coverings affect heat retention. They set up the apparatus shown below to compare feathers and faux fur.

Experimental setup showing two identical glass beakers on heatproof mats. Each beaker contains hot water, has a card lid, and a thermometer inserted through the lid. Beaker A is wrapped in a layer of feathers. Beaker B is wrapped in a layer of faux fur.

Describe a control that the students could use in this investigation to show that the coverings affect the rate of cooling.
