Science Assessment ~ Topics ~ Energy: Forms, Transformation, Transfer, and Conservation ~ Misconception RGM003

The temperature of all of the fluid is the same when convection currents are cycling (Chiou, NARST 2012). The amount of thermal energy the fluid has while convection occurs within the fluid is the same throughout the fluid.

Items that test for misconception RGM003 in this project (ASPECt) and key idea ()
Item ID Number	Item Description	How Often the Misconception was Chosen	Select This Item for My Item Bank
RG009003	As the water at the bottom of a cup is heated, it becomes less dense than the cooler water above it. The difference in densities causes the warmer water to rise, carrying its thermal energy with it.	11%
RG008003	When a cup of water is heated over a flame, the thermal energy of the water at the bottom increases and the heated water will rise to the top of the cup. The cooler water at the top of the cup will sink to the bottom where its thermal energy will be increased by the flame.	9%
