Procedure and Instructions for Testing of Drinking Water:
Students may expect the tap water to be clean, but isn't it? A good drinking science project can help them learn what water they use.
This framework will help them and do a drinking water test.
Mention Your Hypothesis
A good example would be, “If I test drinking water from different sources, what will I find best in my life?” A bad example would be, “If I drink tap water, what happens?”
Background research
Learn all you can about what water can contain. Research the effects of various pollutants, minerals, etc.
Improve the Drinking Water Test
What type of drinking water test will you use? What types of drinking water will you explore? Will you buy a kit or simply order the appropriate test kits? How do you collect water to make sure you don't change its contents?
What you need for a Drinking Water Test
Students will need Colorimetric test strips in most drinking water tests. Kits are available on the right science websites.
Safe Drinking Water Testing Water is a simple EPA-certified kit that identifies the eight most common levels of contaminants in the water: bacteria, chlorine, lead, nitrates, nitrites, pesticides, pH, and water hardness.
Predicting Results
Write a forecast for your expectations. Will your city tap water be the best in your life? Should your family only pay for bottled water? What do you predict your drinking water test will reveal?
Do Your Drinking Test
Students can choose from many drinking water tests. Here are a few possible tests. Younger students may want to use only one. Adult students can include a series of drinking water tests.
1. Basic: Basic drinking water testing can allow students to test water for alkalinity, chlorine (free and complete), nitrate and nitrite, pH, and water hardness. What is the basic structure of your water?
2. Bacteria: As well as basic drinking water tests, you can test for water bacteria. Water from a drinking fountain can show bacteria accumulating in a bubbler and then bathing in water.
3. City of Water: What is municipal drinking water? You can use the basic drinking water tests above but also check the weights and pillars. Do water pipes contaminate the water?
4. Water Well: Since the government does not inspect private resources, there may be contaminants in the water from which it is taken. What can you find? Can you expect more or less? Can your drinking water test find pesticides if the well is near a farm or garden where it is used?
5. Bottled Water: Is bottled water really pure? Better than tap water or worse? Start a drinking water test and see what you get.
6. Water Cooler: When your water cooler is normal, a large five-liter bottle is turned upside down in a pot of drinking water. Could there be germs on the top of the bottle? Will drinking water tests show these germs?
7. Pet Water Bowl: A small drinking water test will show you what your pet's water contains. An animal container should not be cleaned before testing. Allowing your pet to drink from it will determine whether the water is pure enough for humans or not.
Repeat Your Drinking Water Test
A good scientist repeats tests to make sure the results are the same. You will not have the right results if you do your drinking water test only once.
Review
Analyze your test results. Which water is clean? Which tastes better, looks better, and smells better? From your analysis, do you think your predictions will stick?
Come to conclusions
Conclude your drinking water test. Look at all the evidence and decide what it means for healthy drinking water.
1. Which water contains less pollution?
2. Which water contains fewer bacteria?
3. Which water is best for your health?
Prepare Your Exhibition
Decide in advance what the display will look like and leave plenty of time to complete it. Will you have any pictures? Will you have clear mirrors that contain water samples? How will you show the test strips used?
Most good science projects need a board to show your connection to others. A three-panel display board with a length of 36 by 48 ude length, when opened, is standard. On your board, insert these items.
1. Topic: Make it attractive - and big enough to read from the room.
2. Hypothesis and research: Arrange your information from top to bottom, from left to right, as if you were editing a newspaper page. Enter the Hypothesis and research details on the left side of your board.
3. Materials and Procedures: Place this information under your title in the middle of the board.
4. Data / Charts / Pictures: This goes down the middle of your board.
5. Results and Conclusions: The right side of your board contains the final information about your drinking water test.
A good science project to test drinking water can be fun and exciting, suitable for any age student. The results may surprise everyone.
