Post experiment discussion

Laboratory report format

See how that worked? Use the past tense when referring to what has been done in the experiment, but use present tense when talking about most everything else, such as scientific concepts, explanations, and references to articles. The data indicate that avoiding a low level of physical activity substantially reduces the risk of all fractures, particularly hip fractures—the most devastating of osteoporotic fractures—in men. One guideline for staging the discussion is shown here based on extracts from the discussion in one of the cholesterol reports. Stage 3 Explain your results. In most cases, providing a sample calculation is sufficient in the report. Step 2: Decide the order in which your tables, graphs, or other figures should be presented in the Results section. 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. Certainly the precise consumption of cholesterol was not monitored and could have varied from week to week.

Avoid putting results in the Methods. Step 2: In a second paragraph, decribe anything else you learned from doing the lab. For example: I gave coffee to the students.

A title should use the fewest possible words to adequately describe the content of the report.

What questions might we raise? Graphics need to be clear, easily read, and well labeled e. Content The information you put in the discussion should answer the following questions. Always remember to reference where the experimental procedures are coming from in the pre-lab report. Generally speaking, the Results begins with a succinct statement a sentence or two summarizing the overall findings of the experiment. Did you change anything about them? Consumption of a high cholesterol diet did not significantly increase blood cholesterol concentration over a 12 week period Figure 1. Just be sure to label it so you can refer to it in your writing i. Are they good? For instance, scientific reports are about what is being studied, and not about YOU. You can't really erase anything, anyway, because of the carbon paper below it. 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.

Also, if you make a mistake it's a good idea to keep a record if it so you or someone else trying to do your experiment can remember to not make the same mistake twice.

Always remember to reference where the experimental procedures are coming from in the pre-lab report. 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.

Ten dogs with no previous training were selected for the study.

lab report conclusion

In addition, I think it's actually very good practice for getting across your thoughts about the science you are doing in a manner that the reader can understand.

Also, show all of your work. Never scratch something out completely. Even when your methods and technique are sound and your notes are comprehensive, writing a report can be a challenge because organizing and communicating scientific findings requires patience and a thorough grasp of certain conventions.
