In this experiment you will be determining the Densities of 3 common substances.
Density = Mass / Volume.
Materials
1 Graduated cylinders
3 clear cups
Red, Green food coloring
Corn Syrup
Spring Water (not distilled or tap water)
Vegetable Oil
Plastic spoon
1) Calibrate a scale (zero out the scale and turn the knob on the right end of the scale to calibrate)
2) Measure the mass of a graduated cylinder (measure to the nearest hundredth of a gram using estimated digits). Add this information to the Data table.
3) Add 20-25 ml of water to the graduated cylinder.
4) Measure the volume of water to the nearest tenth of a mL (using estimated digets) and add this to the data Table.
5) Measure the mass of the cylinder and water (measure to the nearest tenth of a gram) Add this mass to the data table.
6) Pour the water into a cup. Add two to three drops of red food coloring to the water and swirl.
7) Rinse the graduated cylinder out; turn the tap water on slowly so that you do not spray others.
8) Repeat steps 1- 5 with oil. (make sure to re-measure the mass of the graduated cylinder)
9) Pour the oil into a clear cup. . Make sure you put the oil in a separate cup than water.
10) Rinse out the graduated cylinder.
11) Repeat steps 1-5 with syrup.
12) Pour the Syrup into a third cup and add 2-3 drops of Green Food Coloring. Stir using the spoon.
13) Once you have filled in the data tables find the mass of syrup used by subtracting the mass of the empty cylinder by the mass of the cylinder and syrup. Then calculate density by dividing the mass of the syrup by its volume.
14) Repeat step 11 for both water and oil.
15) Predict the order of substances in the beaker if you were to add all three substances to the beaker. Write this information under the graph.
16) Put all three substances in to the same cup write down the proper order.
