Density lab is a complete simulation of a classic physical science density lab.The density of various materials ranges significantly from less than water (styrofoam's density is about 0.1 g/cm3) to much greater (Osmium has a density of 22.6 g/cm3.) For example, aluminum has a density of 2.70 g/cm3 whereas a sample of lead has a density of 11.2 g/cm3. The same volume of lead will have a mass over four times that of aluminum!When reviewing the protocol explain: Part A: Tare the scale but record the mass of the beaker and all other steps accurately (read the scale to all decimal spaces). Part B: A graduated cylinder may not be as accurate as what we want. This is the part where we determine if when we read "10.0 mL" if it is in fact 10.0 mL.

To calculate an object’s density, divide its mass by its volume. If the mass is measured in grams and volume in cubic centimeters, the unit of density is grams per cubic centimeter (g/cm3). Calculate the density of each object, and record the answers in the last column of your data table. Label this column “Density (g/cm3).”.Two properties we calculated frequently in this lab were the density and volume. Density is found by dividing the mass (grams) by volume (mL), p=m/v.
