Water Quality Report

Formatting & Content Requirements

100 points in the Test Category

General Format and Style Guidelines:

The following sections need to be included in your lab report:

1. Introduction

2. Materials and Methods

3. Results

4. Discussion

5. Conclusion

6. Water Quality Inforgraphic

1. Introduction

 The introduction defines the subject of the report. It must outline the scientific purpose(s) or

objective(s) for the research performed and give the reader sufficient background to

understand the rest of the report.

§ Provide an overall summary and answer the following questions:

o What is water testing?

o Why is water testing needed? Why is it important to continually test water samples?

2. Material & Methods

This section contains the detailed laboratory procedures for readers and the materials that

were used in order to conduct the water testing.

§ The following need to be included:

o A list of all the materials used in the lab

o The procedures used to complete EACH of the water quality tests

o Example: Chlorine Test

Material: Chlorine testing strips, color chart, and plastic cups for water samples

Chlorine Testing Protocol: Completed on three samples – unfiltered, filtered, and name

brand water sample

1. Fill the well plate with your water sample.

2. Immerse one-inch of the chlorine test strip into the water sample. Remove the test

strip immediately.

3. Wait one minute for the color to develop, determine the ppm using the color chart.

Repeat for the filtered water sample, and the bottled water sample.

3. Results

§ The results section should summarize the data from the experiments without discussing their

implications. The data should be organized into tables and/or figures. Figures and tables

should be numbered separately and should be referred to in the text by number.

 For the tests completed on the selected samples use the table similar to the one on your data

sheet.

Test Completed

Unfiltered Sample

(Sample One – Lindley

& Kittridge)

Filtered Sample (Lindley

& Kittridge)

Bottled Brand Water

(Aquafina)

Chlorine 100 ppm 50 ppm 0 ppm

4. Discussion

 This is where you should include the answers to the pre-lab questions and provide a summary

of your results.

1. Determine if all of your samples were inside or outside of the optimal range determined in

the pre-lab assignment for each of the test conducted.

2. Were there any similarities or trends in your results for the tests you conducted on all of your

water samples? (Hint: Think about the geography of your samples)

3. Compare your results to two other groups. Are there any similarities between your results or

are your results completely unique? Are there any trends? Be specific when comparing

your results.

4. If a sample was outside of the optimal range, what do you think caused the high or low

levels? Is there any consequence to these high/low levels?

5. Was there a difference in the filtered water versus unfiltered water samples? If so, does that

imply filtering water is an efficient way to clean water?

6. Was there a difference between your water sample and the bottled water sample? If so,

what were the differences? Does this mean you will only drink or use bottled water?

7. Based on your results overall, do you think your water samples are safe to consume? Do

you trust the quality of your drinking water? Explain why or why not.

5. Conclusion

 Summarize the entire lab procedure. Highlight the important steps and findings. How would

you improve your experimental outcomes?

6. Water Quality Inforgraphic

 You need to design an inforgraphic about water quality in your community. It MUST be

designed by hand, no computer generated graphics.

NOte: research is required for need information not provide in my notes.
