Unformatted text preview: Laboratory Report Format: Each report is graded out of 100pts and, together, comprise the total notebook score (25%) that contributes to your final grade. ---Pre-Lab [Part 1]--- (30pts): This needs to be done before the beginning of lab. A. Title, date, name, student perm number and TA overseeing the experiment B. Purpose/Objective Give a brief introduction to the purpose of the experiment and the approach to be used. Demonstrate that you understand the objective and the key concepts of the experiment. Do not copy directly from the laboratory manual. Usually, one paragraph will be adequate (less than 1/2 a page). Use only the third person, present tense, passive voice when writing the introduction. For example, using third person: do not say I, we, or our. Speak as if it is happening right now (present tense), but use a passive voice for your verbs. Incorrect Example: “I am preparing cyclohexanol from cyclohexanone by hydride reduction.” Correct Example: “Cyclohexanol is prepared from cyclohexanone by hydride reduction.” Notice the correct example says “is prepared” which uses the present tense and passive voice. It is implied that you are the one performing the experiment so it is redundant to speak in 1st person, which is why you don’t see any grammatical person in the correct example. C. Reaction Diagram (when applicable) This is the balanced, fully labeled chemical equation. Each structure should have its chemical name underneath. Usually, conditions like temperature and the solvent used are indicated above or below the reaction arrow. D. Table of Reagents and Products (All labs) A table of reagents needs to be completed before lab starts. Any theoretical values needed to calculate your answers or to compare your results need to be present. Of course, this is going to require you to read the lab and figure out what exactly you need. For example, in Experiment 1, you will measure the density of given liquids. It is imperative that you find these density values and put them in your table of reagents prior to the lab for your comparison. In lab comparison can greatly avoid making an error. E. Intended Procedure (All Labs) with Flow Chart (when applicable) Demonstrate that you are prepared for lab by giving a brief description of what you actually intend to do in lab experimentally; a “game plan” or checklist written in your own words. This can be written in paragraph form but preferred as a bulleted list. Do not copy directly from the laboratory manual. In addition to this, prepare a flow chart. The flow chart is helpful in visually understanding the steps in the procedure of the lab. It begins with all reagents used and branches when you perform purification. Ultimately, the pure product should be at the end of the road and each branch that leads to a dead end is most likely going to be disposed along the way. The first flow chart you do will be in Experiment 3 and it done for you in the lab write-up. Use this as an example for future labs. Use this as an example for future labs....
