What is a pre lab for chemistry?

The Pre-Lab assignment is simply a means to show that you are prepared for the experiment for the day. Your GSI will also go over any details at the beginning of the lab period. Your Pre-Lab should be written in you lab notebook before you come into the lab.

What is a lab notebook for chemistry?

The purpose of a laboratory notebook is to legally record the experiments performed by a certain person in an organized format that can be used as a reference. Every discipline has subject specific lab notebook rules. The GTC Chemistry rules are: Use a bound composition notebook only.

How do you keep a lab notebook chemistry?

General tips

1. Use permanent ink.
2. Initial and date every page.
3. Leave a blank page or two at the beginning of your notebook so you can create a Table of Contents.
4. Draw only a single line through all errors written, so they still can be seen.

What is the purpose of a lab notebook?

lab notebook or lab book) is a primary record of research. Researchers use a lab notebook to document their hypotheses, experiments and initial analysis or interpretation of these experiments.

What are the requirements of keeping a laboratory notebook?

The laboratory notebooks should contain a summary of the information in those files and also give the name of the file (and format) in which the data are stored. The electronic data should be backed up and archived weekly. A new and separate file should be provided as a place to store data.

Are lab notebooks legal documents?

A laboratory notebook provides a permanent record of research, ideas, concepts, data, analysis, and/or observations. It is a legal record of your work and may be used as evidence for patent filing, patent protection, or other legal purposes. A laboratory notebook is a legal document and must be handled accordingly.

What should a lab notebook look like?

Your notebook should be like a diary, recording what you do, and why you did it. You should feel free to record your mistakes and difficulties performing the experiment – you will frequently learn more from these failures, and your attempts to correct them, than from an experiment that works perfectly the first time.

How do you prevent data loss in a lab notebook?

If this results in blank pages appearing in your notebook, simply draw a single diagonal line across the blank page(s) to avoid additional data entry; positioning the start of each experiment on an odd page will make it easier for you to locate experiments at a later date.

What is the purpose of a chemistry lab?

The purpose of the laboratory component of the course is several-fold. It reinforces the material you have learned in class and it gives you a chance to apply your knowledge. You will learn some important experimental techniques that are necessary for you to become an effective chemist.

What is the purpose in a lab?

One very important piece of the lab report is the purpose statement. This statement captures the original purpose of the test, experiment or research. The purpose statement is referenced various times throughout the lab report. Figure out what the purpose of your test, experiment or research actually is.

How do you write a lab introduction?

Sometimes an introduction may contain background information, briefly summarize how the experiment was performed, state the findings of the experiment, and list the conclusions of the investigation. Even if you don’t write a whole introduction, you need to state the purpose of the experiment, or why you did it.

What is a laboratory?

1a : a place equipped for experimental study in a science or for testing and analysis a research laboratory broadly : a place providing opportunity for experimentation, observation, or practice in a field of study.

What is laboratory report writing?

Lab reports are written to describe and analyse a laboratory experiment that explores a scientific concept. They are typically assigned to enable you to: Conduct scientific research. Formulate a hypothesis/hypotheses about a particular stimulus, event, and/or behaviour.

Does hypothesis come before aim?

The aim of an experiment is the objective. If a hypothesis was formulated before the experiment was done, than it should be written here.

How do you start a hypothesis for a lab report?

The steps below form the basic outline of the Scientific Method:

1. Ask a Question.
2. Do Background Research.
3. Construct a Hypothesis.
4. Test Your Hypothesis by Doing an Experiment.
5. Analyze Your Data and Draw a Conclusion.
6. Communicate Your Results.

How do you start a hypothesis?

However, there are some important things to consider when building a compelling hypothesis.

1. State the problem that you are trying to solve. Make sure that the hypothesis clearly defines the topic and the focus of the experiment.
2. Try to write the hypothesis as an if-then statement.
3. Define the variables.

What are examples of hypothesis?

Examples of Hypothesis:

• If I replace the battery in my car, then my car will get better gas mileage.
• If I eat more vegetables, then I will lose weight faster.
• If I add fertilizer to my garden, then my plants will grow faster.
• If I brush my teeth every day, then I will not develop cavities.
