J. Test Tube
K. Graduated Cylinder
L. Water
III. Procedure
• Put on Safety Goggles.
• Bunsen Burner Lab o Attach Rubber hose to gas line o Turn Gold knob counter clockwise to allow gas o Open ports for air. o Turn gas on o Light with striker the Bunsen Burner o Adjust gas to quiet steady flame. o Using crucible tongs hold piece of copper for five seconds over Bunsen Burner in different parts of the flame o Turn off Bunsen Burner using gas knob
• Sugar Lab o Zero out Electric Scale. o Put 2.75g of Sugar on Paper o Fold Tray in half and pour sugar in to small test tube. o Rinse and discard materials
• Water Lab o Make Procedure o 3 different amounts of water in Graduated Cylinders and record. o Measure mass on scale to find weight or mass of water o Divide weight by volume
IV. Analysis
• Observations o For Sugar Lab I observed the weight of the Sugar and observed it transfer to the shape of the test tube when put in the test tube. o During Copper Lab I observed copper change from copper brown tint, to a gray silver tint. o Water lab I observed the comparison between volume and mass.
Mass (g) Volume (mL) Density (g/mL)
3.9 4.9 0.79591837
33.48 34.81 0.96179259
49.58 50.5 0.98178218

Conclusion
• This lab has shown that the data was collected mostly responsible through consistency of the Water lab.
• In theory even when you change the amount of liquid the density ratio of water should not change because you are changing the variables only.
• This shows almost accuracy because we got densities very similar on our three different
