Will the concentration of copper sulphate affect the amount of copper produced?"i
Max : I was impressed about the pictures in the method, which enables readers to understand the method easily. In addition, the method is clearly and carefully stated for easy understanding. However, in the data collection, the table was not uploaded by the image, but by the excel file itself. In addition, the hypothesis does not include any explanations. Also, the conclusion part is not clearly stated, too short and simple.

Lily: This is a well-done lab report which shows very thorough details about the procedure and helpful pictures which provide background information for the experiment. However, when reviewing it, some mistakes emerge as well. The aim for this lab is to find out how does the concentration of the copper sulphate affect the mass of copper produced. The hypothesis suggests that the increase in the concentration of the reactant will increase the final mass of the copper produced. Those information all give me a feeling that the experiment is all between the concentration of the reactant and the mass of the product. Nevertheless, the method and the table suddenly include the temperatures of the products and their changes over time into the experiment. The temperature factor is not mentioned or explained in the previous aim or hypothesis. This causes some confusion and misunderstandings. The tables and the graph that are included in the lab report are pretty interpretable and meaningful. But some amendments are also necessary for the tables. If the scientists who write this lab report want to include two tables in their lab report, they should number the tables consecutively. Also, the table (the one with the link) does not meet the requirements. It doesn't have a title, and it runs over two pages as well. In a scientific lab report, pronouns such as "you", "we" should be avoided. The people who write this l report use those words in their evaluation. Those words should be considered to be replaced with words like "the", "it" or more exact words.

David: Good work group 1! I liked your lab report, it is easy to undertand and the method part was very detailed with the support of those clear images. But the conclusion is a bit too short, I prefer you can tell why there's more amount of copper produced when higher the concentration of the zinc sulphate solution. And it is better to state how many of each material you used so it will be more specific. Also, you can avoid those nouns such as "you","we" etc. Good job! We all know this is not a easy work.

Ms Jordan: Don't forget to write a balanced chemical equation for all chemical reactions and remember that recording qualitative observations are an important part of all data collection. Do you have a further question or idea for an investigation that is related to the speed of chemical reactions?
