Density Report Rubric Chemistry 30A – Point allocations are outlined for each section of the density Report. Section 1 Introduction Section – 5 points: a) Purpose statement is clearly defined for the experiment (no spelling errors present or just one is OK). b) Definition of density given (formula) c) How will density be determined? d) How can density information be used to explain such phenomena as steel and cement ships that are capable of floating in water? e) A discussion of how the results of density data determined in the experiment will be used. 4 points: If any one of the points is missing or poorly written 3 points: If any two of the points is missing or poorly written 1-2 points: If this section is poorly written in general and only one or two of the above points are addressed. Many spelling errors present. Section 2 Experimental Section – 5 points: a) Experimental procedure is written in complete sentences and follows a logical progression b) A table listing of all of the chemicals and equipment used c) The table must have a title and a number associated with it: Table #1 d) Correct spelling 4 points: Everything from above is correct except one item is not done correctly. For example: The table is not labeled correctly, a few spelling errors. Procedure description is not complete. 3 points: A number of spelling errors, poorly constructed table and equipment and chemical lists are incomplete. Procedure section is missing a few major parts. 1-2 points: Many spelling errors, no table, very incomplete list of chemicals and equipment. Procedure section is very incomplete or missing altogether.
