Conduct an investigation: sample 50 people regarding any hereditary characteristic you choose. Write up a lab report following proper format. Proper lab Report Form Here are the main elements found all lab reports, and a brief description of what they entail: Purpose This is where you get to state why you are doing the experiment. It is usually in the form of a question to guide your research or investigation. Introduction In a few words tell what you already know or have found about the problem that will let you make an educated guess. This is your background information from the text, teacher, or other sources. It gives the reader an understanding of underlying principles and content information of the laboratory. Hypothesis: What do you expect to find? The hypothesis can be stated as an "If..., then..." statement. The ''If'' part of the statement is based on related facts that you know to be true. The ''then'' part of the statement is an educated guess on the outcome of the experiment. The hypothesis does not have to guess the correct outcome, but the experiment must be set up to test the hypothesis. Materials Simply a list of everything you used to carry out the the experiment. Include quantities and sizes. Procedure Be specific. The procedure you use affects the results. So, it is important to be accurate in explaining what you did as you carried out your experiment. It may be written in point form or as a paragraph. Either way, because it is a description of what you did and is thus written in the past tense. You may include a sketch of your equipment setup to show more clearly how you proceeded to carry out your experiment. Observations The observations tell exactly what happened when you did the lab. Some observations may be measurable information that comes to you through your senses. Results include experimental (raw) data in the form of well-labeled tables, graphs, drawings and other observations. Place your observations and data in this section without discussion or comment. This is also where you include any calculations made during the experiment. Conclusion Conclusions explain your observations and describe how the data you collected relates to the purpose of your experiment. It is written in paragraph form and should include why you did this experiment. You should explain in your own words what you found out or discovered. Your conclusion should state whether or not the data confirms or rejects your hypothesis. Discuss any errors as well as any patterns you see. Part of the conclusion may be a new hypothesis based on your findings and suggestions for testing the new hypothesis in a different experiment. You may also make any predictions you would expect based on what you discovered. Discussion This is where your questions are usually answered if they are provided. If no questions are provided, then it is here that you discuss various aspects of your experiment, such as where you may have made errors, problems with equipment, problems with the design of the experiment, etc.
