Sensing anything involves both physiological and behavioral components. We have physiological receptors that allow our nervous system to capture sensory information (for example light waves – seeing, oscillations of the air – hearing, or internal chemical changes – feeling). We also have a learning history that makes us aware of only the sensory information that has been historically important.

This question is worth 10 extra credit points. A student is attempting to determine the density of an irregularly shaped metal object. The mass of the metal is measured as 85.42 grams using an analytical balance. To find the volume, the student uses a graduated cylinder partially filled with water. The initial volume of water is 45.0 mL. After carefully adding the metal sample, the water level rises to 54.8 mL. The student records the following calculation for density: Densitymetal = 85.42 g x 54.8 mL = 4681.0g/cm She concludes that because this value is much larger than the density of water (1.00 g/mL), the metal must float. Task:Identify two errors in the student’s calculation and/or reasoning. Consider errors related to the mathematical setup, the use of units, significant figures, and the interpretation of the density concept. For each error, explain why it is incorrect and provide the correction.
