SCI 207 Week 5 Assignment Final Lab Report updated

 

Abstract

 

The abstract should provide a brief summary of the methods, results, and conclusions. It should very briefly allow the reader to see what was done, how it was done, and the results. It should not exceed 200 words and should be the last part written (although it should still appear right after the title page).

 

Introduction

 

The introduction should describe the background of water quality and related issues using cited examples. You should include scholarly sources in this section to help explain why water quality research is important to society. When writing this section, make sure to cite all resources in APA format.

 

The introduction should also contain the objective for your study. This objective is the reason why the experiment is being done. Your final report should provide an objective that describes why we want to know the answer to the questions we are asking.

 

Finally, the introduction should end with your hypothesis. This hypothesis should be the same one posed before you began your experiment. You may reword it following feedback from your instructor to illustrate a proper hypothesis, however, you should not adjust it to reflect the “right” answer. You do not lose points for an inaccurate hypothesis; scientists often revise their hypotheses based on scientific evidence following an experiment. Include an explanation as to why you made the hypothesis that you did.

 

Materials and Methods

The materials and methods section should provide a brief description of the specialized materials used in your experiment and how they were used. This section needs to summarize the instructions with enough detail so that an outsider who does not have a copy of the lab instructions knows what you did. However, this does not mean writing every little step like “dip the chloride test strip in the water, then shake the test strip,” these steps can be simplified to read “we used chloride test strips to measure the chloride levels of each sample in mg/L”, etc. Additionally, this section should be written in the past tense and in your own words and not copied and pasted from the lab manual.

 

Results

 

The results section should include all tables used in your experiments. All values within the tables or graphs should be in numerical form and contain units. For instance, if measuring the amount of chloride in water you should report as 2 mg/L or 0 mg/L, not as two or none.

 

The results section should also highlight the important results in paragraph form, referring to the appropriate tables when mentioned. This section should only state the results as no personal opinions should be included. A description of what the results really mean should be saved for the discussion. For example, you may report, 0mg/L of chlorine were found in the water, but should avoid personal opinions and interpretations of the data (e.g., “No chlorine was found in the water showing it is cleaner than the others samples”).

 

Discussion

 

The discussion section should interpret your data and provide conclusions. Start by discussing whether you accepted or rejected your hypothesis and how you arrived at this decision. In the same section, consider some of the implications of your results. Given the chemical differences you may have noted between the water samples, are any of the differences causes for concern? Why or why not?

 

The discussion should also relate your results to the bigger water concerns and challenges. For example, based on your experiments you might discuss how various bottled water companies use different filtration systems. Or, you could discuss the billion dollar bottled water industry. For example, do you think it is worth it to buy bottled water? Why or why not? Your final lab report should utilize credible and scholarly resources to put your results into context.

 

Finally, the results section should also address any possible factors that may have affected your results, such as possible contamination in the experiments or any outside factors (e.g., temperature, contaminants, time of day). If so, how could you control for these in the future? You should also propose some updated questions that have arisen from your results and what kind of experiment might be proposed to answer these questions.

 

Conclusions

 

The conclusion section should briefly summarize the key findings of your experiment. What main message would you like people to have from this report?

 

References

 

Include at least two scholarly references, two credible references, and your lab manual in APA format.

Lab 4 – Energy Sources and Alternative Energy

 

Experiment 1: The Effects of Coal Mining

Coal mining, particularly surface mining, leads to large areas of land being temporarily disturbed. Mines collect and conduct water that is in contact with pyrite, a mineral that produces iron and sulfuric acid when exposed to air and water. Limestone is often used to mitigate the effects of pyrite on water. In this lab, you will see first-hand the reasons why mine drainage can be harmful to the local drainage system if left untreated.

 

POST-LAB QUESTIONS

 

1. Develop hypotheses predicting the effect of pyrite and limestone on water acidity? Why would you predict these effects?

 

a. Pyrite hypothesis =

b. Limestone hypothesis =

 

2. Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Why?

 

a. Pyrite hypothesis accept/reject =

b. Limestone hypothesis accept/reject =

 

3. Based on your data, what effect do you predict coal mining has on the environment?

 

Answer =

 

4. Based on your data, why would you use limestone to treat acid mine damage? Utilize at least one scholarly resource to support your suggestions.

 

Answer =

SCI 207 Week 3 Assignment Outline of the Final Lab Report updated

 

Introduction

 

Body Paragraph #1 – Background: The rough draft of the introduction should describe the background of water quality and related issues using cited examples. You should include scholarly sources in this section to help explain why water quality research is important to society. When outlining this section, make sure to at least list relevant resources in APA format that will be used in the final paper to develop the background for your experiment.

 

Body Paragraph # 2 – Objective: The rough draft of the introduction should also contain the objective for your study. This objective is the reason why the experiment is being done. Your rough draft should provide an objective that describes why we want to know the answer to the questions we are asking. Make sure the objective ties back to ideas you discussed in the Background, above.

 

Body Paragraph # 3 – Hypothesis: Finally, the introduction should end with your hypothesis. This hypothesis should be the same one that you posed before you began your Drinking Water Quality experiment. You may reword it following feedback from your instructor to put it in better hypothesis format; however, you should not adjust it to reflect the “right” answer. You will not lose points if your hypothesis was wrong; scientists often revise their hypotheses based on scientific evidence following an experiment. In addition to stating the hypothesis, offer your rationale for it; in other words, why did you make that particular hypothesis?

 

Materials and Methods

Body Paragraph # 1: The rough draft of the materials and methods section should provide a brief description of the specialized materials used in your experiment and how they were used. This section needs to summarize the instructions with enough detail so that an outsider who does not have a copy of the lab instructions knows what you did. However, this does not mean writing every little step like “dip the phosphate test strip in the water, then shake the test strips,” these steps can be simplified to read “we used phosphate test strips to measure phosphate levels in parts per million”, etc. This section should be written in the past tense and in your own words and not copied and pasted from the lab manual.   Think cookbook recipe here; you should explain enough of what you did for others to repeat the experiment, but with nothing extra added.

 

Results

 

Tables: The rough draft of the results section should include all the tables used in your experiment. All values within the tables should be in numerical form and contain units (except pH, which does not have any). For instance, if measuring the amount of chloride in water you should report your measurement as 2 mg/L or 0 mg/L, not as two or none.

Body Paragraph # 1: The rough draft of the results section should also highlight important results in paragraph form, referring to the appropriate tables when mentioned. This section should only state the results; no personal opinions should be included. A description of what the results really mean should be saved for the discussion. For example, you may report, 0mg/L of chlorine were found in the water, but should avoid personal opinions and interpretations such as, “No chlorine was found in the water, showing it to be cleaner than the other samples.”

 

Discussion

 

Body Paragraph #1 – Hypothesis: The rough draft of this section should interpret your data and provide conclusions. Start by discussing if your hypothesis was confirmed or denied and how you know this. Then consider some of the implications of your results. Given the chemical differences you may have noted between the water samples, are any of the differences causes for concern?

 

Body Paragraph # 2 – Context: The rough draft of your discussion should also relate your results to bigger water concerns and challenges. For example, based on your experiment you might discuss how various bottled water companies use different filtration systems. Or, you could discuss the billion dollar bottled water industry. For example, do you think it is worth it to buy bottled water? Why or why not? Your outline should at least list some of the resources that you plan to utilize in your final paper to put your results into context.

 

Body Paragraph #3 – Variables and Future Experiments: Finally, the rough draft of your results section should also address any possible factors that affected your results, such as taking measurements over two different days instead of all at once. If possible sources of error were present, how might you control for these in the future? You should also propose some updated questions that have arisen from your results and what kind of experiment(s) might be devised to answer these questions.

 

Conclusions

 

Body Paragraph #1: This section of your rough draft should briefly summarize the key points of your paper. What main message would you like people to take way from this report?

 

References

 

Include at least 2 scholarly and 2 highly credible sources as well as your lab manual, in APA format.
