How could the student whose report you received have improved his or her lab report?

Report 3 could have been improved by talking about what sodium carbonate and sodium bicarbonate is in the introduction as well as removing the lists under Materials and Methods. The Materials and Methods should always be in sentence form in the past tense. Also more than two trials should have been done because replication is very important to scientific experiments. This ensures that there are no outliers in the results. Also, the author should have avoided personal pronouns like “I” in the conclusion. A sentence that could replace the last would be something like “Because the actual percent composition of the mixture is unknown, the accuracy of the current …show more content…

First, there are journals where scientists are welcome to publish their findings. This is an easy way for scientists to have easy access to work done by other professionals in their field. However, this is not the only method of communication. They can also give presentations at things such as TED talk that allows them to display their results to an interested audience. In a like manner, the media often finds research done by scientists and publishes it. This is not as common though because the media is more interested in stories that will get them more attention from the public. Due to this, they often only publish findings that tend to be simple and relevant to most people since scientists are often only a minority in the public.

What makes a good lab report? A good lab report is clear and concise. It includes a number of things but the foundation is giving the lab report good background information, having clear information, and clear data. A lab report must have a good abstract, discussion, procedure, observation, calculations, and conclusion. Also, it must have labeled graphs and tables if applicable. …show more content…

In this case, the grams of sodium carbonate (Na₂CO₃) is what is measured after the reaction takes place. Sodium carbonate and sodium bicarbonate is what makes up the initial mixture. Therefore, the leftover sodium carbonate can be reused allowing this experiment to fit in the definition of green chemistry.
When comparing the results above, the outlier of the data,1.358% NaHCO3, was inconsistent with the other data. This caused the average of the data above to be significantly less than the other averages displayed. The averages being discussed represent the amount of NaHCO₃ that is present in the reactant. Groups 1 and 4 had very similar data to the data above. Two of the values that were pretty consistent seemed to be 38% and 57% NaHCO3 in mixture. This means that the two mixtures had approximately the same amount of sodium bicarbonate to begin with. However, the differences in average shows that each different mixture is composed of different amounts of sodium bicarbonate and sodium carbonate. Although they seemed to be similar mixtures, the amounts of each substance are inconsistent for
