Where would each of the four solid materials be located?
The beaker shown below contains four liquids of different densities. The blocks shown in the beaker present four different solid materials. The table below shows the densities of the four solid materials. Corn oil (0.925 g/cm3 ) Water (1.00 g/cm3 ) Glycerol (1.26 g/cm3 ) Corn syrup (1.38 g/cm3 ) Name of Liquid (density) Name of Solid Material Solid Material Density (g/cm3) copper 8.90 plastic 1.17 rubber 1.34 wood 0.71 Density of Solid Materials Sugar (1g) Sugar (1g) Sugar (1g) Cold water (250 mL) Hot water (250 mL) Hot water (250 mL)
Allow a maximum of 2 credits, allocated as follows:
Allow 2 credits if all four materials are correctly labeled as shown in the diagram below.
Allow 1 credit if only two or three materials are correctly labeled.
Example of a 2-credit response:
Note: Allow credit if the student lists the densities in correct order instead of listing the names of
the solid materials.
