Above is a picture created to show one of the main misconceptions in the assessments we are seeing. The red arrows are what students are using to show that the block would sink and then float back up to the surface to rest. This is showing the misunderstanding that the block itself is the force rather than the gravity and buoyancy playing a role on what the block is doing. To show a correct answer, the black arrows are more of what we are hoping to see.
