Introduction The introduction discusses the problem being studied and the relevant theory. The Discussion section often begins by making a statement as to whether the findings in the Results support or do not support the expected findings stated in the hypothesis.
In one sentence, state what you are going to do in the experiment and what you hope to find. Also, it gives you a chance to explain anything that might have gone wrong or could be improved, as well as propose future experiments.
Like the introduction, it should be short and to the point. Ideally, it would take up about sentences. The hypothesis is what you anticipate will be the outcome of the procedure, typically the results of the measurements of the dependent variables when the independent variable s is manipulated.
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. The reason you have a conclusion is because your lab report might be long and the reader may not remember all the important points that you how do you write a pre lab for chemistry.
This is actually a pretty powerful tool because if your answer has the wrong units you know you must have made an error somewhere along the way.
This is the kind of question you need to ask yourself. This is exactly why we want you to do it. This prediction is based on your understanding of the scientific concept of the lab.
Often the objectives are listed in the lab manual. 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 can even do the calculation using just units and no numbers and see if the units cancel out in the right way to test if you method is good this is called dimensional analysis.
Speculate on possible sources of error. There are three basic parts to a lab report: Or you can add anything else that you might think is relevant, like additional major procedural steps you will take.
Recopy your data from the in-lab here in a nice neat format tables are usually nice and neat. Read over the objectives again. Objectives are the activities you are being asked to do in order to complete the lab experiment.
Why or why not? Your hypothesis may be stated in sentences or sketched out as a graph. Procedural Flowchart This part of the pre-lab should take no more than one page. Write a paragraph or so describing the logic you used to go from your understanding of the scientific concept to formulating a prediction of the outcomes of the experimental procedure.
In other words, show the link between your response to question 2 what you will do in the lab to your response to question 1 what you are supposed to be learning about by doing the lab. What is the overall purpose of the lab?
If your experimental error RAD, RSD is small or large compared to the inherent error the error in the standards and equipment usedcomment on what this means, too. That way, if you make some amazing discovery, like blue aspirin is better than white aspirin btw: If they are not listed in the lab manual, read the lab procedure and figure out from the procedure what the objectives of the lab are.
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. What scientific concept s is this lab about? White-out is a big no-no, too. If it turns out that you get an unexpected result, you can go back and trace your observations to see where the error occurred.
The main purpose of writing a lab report, of course, is not to contribute to the knowledge of the field; but to provide you the opportunity for learning. It will be something like photosynthesis, chemical reactions, or inertia. They outline what you will be doing in the lab experiment.
In most lab classes, you will have a lab manual that contains background for the lab and directions for doing the lab procedure. So the hypothesis is what you expect, based on your understanding of the scientific concept of the lab--what the relationship among the variables will be.Some Tips on Writing Lab Reports.
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). This part of the pre-lab should take no more than one page.
A good flowchart should give a reader. The main purpose of writing a lab report, of course, is not to contribute to the knowledge of the field; but to provide you the opportunity for learning.Ý That's why it's important to begin the lab by establishing that learning context.Ý The learning context provides a way for you to situate the lab report within the overall purpose for doing.
Apr 03, · Introduction: How to Write a General Chemistry Lab Report By karadragunas Follow This instructable will teach you how to write a simple yet proper lab report for a college level General Chemistry lab course.
Pre-Lab Guidelines Please follow the format provided below for your pre-lab write-up. The pre-lab assignment is intended to prepare you for the lab and therefore should be written in your lab notebook before you come to the lab.
CHEM and – Organic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS Do not write on loose sheets of paper, or even in spiral notebooks from where pages can be torn.
Use a hardbound notebook, with numbered pages, that makes carbon copies as you write. That makes it easy.
