The purpose should be several well constructed sentences that describe the topics this experiment is designed to cover and the desired result. This should include both concepts and experimental techniques. The procedure section should reference the lab manual and note any changes that were made to the procedure while performing the experiment. Make sure to note which method you used when the procedure gives you a choice.
The data section should include all observations made during lab. The data table for determining the density of a metal should include the following information a) the measurements of the metal unknowns, b) the volume of metal unknowns, c) mass of the metal unknowns d) the density of the metal unknowns and e) identity of metal unknown. The second data table with the submarine data should include a) mass of graduated cylinder, b) volume of ocean water, c) mass of water, d) weight of balloon with weights, e) density of ocean water, f) volume of balloon needed to match salt water density, g) final volume of submarine design and h) final density of submarine design.
The calculations section should have example calculations of the following: a) the volume of the unknown metals, b) density of unknown metals, c) percent error between known and unknown metal densities, d) mass of water, e) density of ocean water, f) volume of balloon needed to match salt water density, g) final volume of submarine and h) final density of your “submarine”.           
The conclusion section should be in paragraph format. This section should report the results from the data section. For the density of the metal object section be sure to report the density and identity of the unknown metals. Discuss any differences between the experimental and theoretical densities of the metals and the percent error. Also discuss any experimental errors that might have led to these differences. For the submarine data, report the density of the ocean water, the ideal volume of the submarine and the final volume and density of the submarine. Discuss the trial and error portion of making the submarine and the differences in the ideal volume of the submarine and the final volume of the submarine. Finally discuss any errors in the submarine design and the experiment.
Answer the following Questions:

1. Do you think your submarine will make it to Hawaii? Why or Why not?
2. Give an example of the use of density (other than submarines) that you have observed in your own life.
3. What is third person neutral and why is it used in the writing of scientific papers?
