Step 1: Planning
• Choose a water point in your area (e.g., a lake, pond, river, stream, artificial pond, well).
o If you don’t have access to this type of water source, you can test the tap water in your school or home.
• Formulate water quality issues for the target water point, for example:
o Where does this water come from?
o What are the risk factors that expose them to contamination?
o What human activities take place near this water point?
o How can we clean up contaminated water?
• Make an assumption about the quality of the water drawn from the water point you have chosen as well as about sanitation methods.
• Find reliable sources (more than one source should be used).
• Develops a protocol for filtering a contaminated water sample.
o Have it approved by your teacher before committing to the next step.
Step 2: Research and Experimentation
• Conduct research on the sources of contamination of water points of the same type as the one you have chosen and on the impact that human activity can have on it.
• Research methods to filter or clean contaminated water.
• Collect the material and products needed to carry out your experimental protocol of filtration of your water sample.
• Choose the ideal time to perform your experiment and to draw the sample of water to be analyzed.
• Take note of the exact location, date and time of your data collection, and weather conditions, if applicable.
• Take note of any difficulties encountered during your data collection as well as any other information you deem relevant.
• Proceed with the manipulation proposed in your experimental protocol.
• Record your qualitative observations of your water sample (before, during and after). Describe in detail what you can see with the naked eye or with a magnifying instrument allowing you to distinguish the finest details, if you have such an instrument.
• Records quantitative observations of your water sample (before, during and after) (e.g., tests pH and temperature).
Step 3: Analysis
• Find standardized data to compare your results with the literature.
• Analyzes and synthesizes information collected (e.g. process data, create graphs).
• Answer some questions based on your analysis:
o Why are some contaminants considered acceptable for health or the environment? Give an example.
o Where do you think these compounds come from that are possible to find in your sample? Can you determine that accurately?
o Does the use of home filtration techniques ensure the safety of the water collected?
• Demonstrates, based on examples, the impact of certain chemical compounds on water quality and on the conservation of the chosen water point.
• Draws a conclusion about contaminants and their source.
• Propose solutions to revitalize the chosen water point according to the contamination problems you observed there or propose solutions to maintain the safety of the water coming from this water point.
Step 4: power point
• Presents the information gathered during your experiment.
• Determine the method of communication you will use to make the local population aware of the conservation of the water point you have chosen or to promote its revitalization (e.g. local newspaper article, radio interview, city website post, open letter, social media campaign)
• Prepare your content based on your target audience and the mode of communication chosen.
• Uses the correct vocabulary associated with water chemistry and solubility, and populates concepts so that they are understood by your target audience (e.g. miscible, dissociation, neutralization, parts per million, parts per billion).
• Review your work before submitting
