How do you write a pre lab for chemistry

What you write in your laboratory notebook is an actual account of what you have done in a given experiment, like a very detailed diary. You should be able to come back to it at some point, read what you wrote before, and reproduce what you did before.

So should anyone else reading your notebook, for that matter. That way, if you make some amazing discovery, like blue aspirin is better than white aspirin btw: There are three basic parts to a lab report: Introduction The introduction discusses the problem being studied and the relevant theory.

Ideally, it would take up about sentences. The main idea here is to give the reader an idea of what you are going to do in a short paragraph. There are different styles to do this. You should try to write it in your own words, rather than paraphrasing or quoting the lab manual but if you have to, be sure to include the appropriate references.

I suggest the following: In one sentence, state what you are going to do in the experiment and what you hope to find. This is probably the most important part of the introduction. You should also list explicitly any main chemicals with which you are dealing vinegar, aspirin, NaOH and any techniques you will be utilizing titration, recrystallization, spectrophotometry, etc.

Or you can add anything else that you might think is relevant, like additional major procedural steps you will take. Procedural Flowchart This part of the pre-lab should take no more than one page. Think of a flowchart as a "road map" of the experiment. It gives a reader a "pictorial" representation of the experimental procedure.

What your approach says about you Each element should be followed by the punctuation mark shown here. Earlier editions of the handbook included the place of publication and required different punctuation such as journal editions in parentheses and colons after issue numbers.

PreLab SelfGuide In most lab classes, you will have a lab manual that contains background for the lab and directions for doing the lab procedure.

In general there are two major steps when constructing the flowchart. First, read the experimental procedure carefully.

Second, rewrite the procedures in a flowchart format. Keep in mind that the flowchart should be brief and cover all the steps in a simple and easy to follow manner. There should be no complicated sentences or paragraphs in the flowchart. You will have to do a lot of rewriting in order to simplify the procedures into a flowchart format.

This is exactly why we want you to do it. This gives you a chance to THINK about what you read and how to rewrite it in a way that can be implemented into a flowchart.

Always remember to reference where the experimental procedures are coming from in the pre-lab report. Please DO NOT simply copy the entire procedure or majority of the procedure and make it looks like a flowchart.

Data-taking Always write in pen. White-out is a big no-no, too. Always record data directly into your lab notebook. Never scratch something out completely. Observations In addition to writing down all those numbers datayou should keep an eye nose, ear, etc. If you add one thing to another and it evolves a gas, gets hot or cold, changes color or odor, precipitates a solid, reacts really quickly or slowly, or anything noticeable, you should write down that observation in your lab notebook.

Other things to consider including are: One of the reasons you are doing this goes back to what I said about mistakes earlier. An experiment is exactly that: If it turns out that you get an unexpected result, you can go back and trace your observations to see where the error occurred.

Recopy your data from the in-lab here in a nice neat format tables are usually nice and neat. This is your chance to organize it into a more readable form now that you are done with the experiment and impress the TA with your organizational skills. Personally, I like to work through the problem using just the formula, and then plug in the numbers at the end to get my final answer.Science Supply Store offers Lab Supplies and Equipment, ECO Funnels, Nalgene Lab Bottles, Pharmacy Vials and Containers, Safety Storage Cabinets and Safety Cans.

Break through to improving results with Pearson's MyLab & Mastering. We're working with educators and institutions to improve results for students everywhere. Write in the third person - Scientific experiments demonstrate facts that do not depend on the observer, therefore, reports should avoid using the first and second person (I,me,my,we,our, OR us.).

Using the correct verb tense - Lab reports and research papers should be mainly written in the present ashio-midori.com should limit the use of the past tense to (1) describe specific experimental methods.
