Aluminum Atoms Lab Report Rubric

Format – 4 points for the following: Typed, neatly organized, sections separated and clearly titled, single-spaced with size 12 font. Purpose – 1 point State the purpose of the experiment…what were you trying to accomplish and in very general terms, how did you do it? Procedure – 1 point Your pre-lab assignment serves as a statement of procedure for your lab. You do not need to re-write the procedure here…a simple statement of “See Prelab for Procedure” is fine. Data Table – 5 points Formatted with gridlines for easy reading, the data you collected in the lab is provided here with appropriate units and headings. Data Analysis – 12 points Show your calculations for the following as described in the lab handout: 1 – volume of your “block” 2 – volume of foil 3 – thickness of foil (in cm) 4 – thickness of foil (in atoms) You must show all work in this section! Include a title (what is being calculated?), a word equation (how do you calculate it?), and a numerical equation. Every answer gets a unit!!! Results / Discussion – 6 points Provide a results table that summarizes all of the results that you found above. This table will provide your calculated results only, not data you included in the data table. In addition, you will answer question # 5 in this section. Conclusion – 4 points Your conclusion is a RESTATEMENT of your entire lab report in about 5 sentences. You should restate the purpose of the lab. Then summarize your procedure in a sentence or two (NOT EVERY DETAIL…JUST A SUMMARY OF METHODOLOGY). Next, you will summarize the results that you got that actually answer the purpose (hint, if your objective was to determine the number of atoms that could stack on top of each other to fit in the thickness of your foil, does the volume of your block answer that question?). Finally, provide a conclusion statement that ends the entire thing…”This result showed me that there are a whole lot of atoms in the thickness of foil…no wonder they’re so difficult to study!” or something else that shows me you achieved your objective.
