Recommended Resources: To filter the sample, drag the test tube towards the funnel. Collect the water that passes through in a beaker. For this experiment we wanted to demonstrate the importance of wetlands on the water filtration process. as a qualitative observation. The next step is to create a solution of salt water by pouring the salt into a cup of warm water and stirring. These products were used to determine how well the purification process of water works. Place a full cup of water in front of a sunny window. When salt is dissolved in water, as it is in ocean water, it adds to the mass of the water and makes the water denser than it would be without salt. Therefore, we applied a pre-filtration method to better detect . Have fun with this experiment! 1 grams of sand, and 2. Of this tiny amount of freshwater, much is locked up in ice and glaciers. As a result, these impurities are trapped by the filter paper because they are unable to move through the pores also known as residue. Filter Your Water and Make Observations: 5. Step 4. Watch as the filter works its magic and cleans the water! The experiments have been selected by the Young . You will see it does not stick to the funnel. When trying each material alone they all had pollutants that they were capable of removing with the exception of the food coloring which represented the chemicals in the water. Fill a measuring cup with 1/2 cup of water. The salt makes the water denser than it would be without the salt. In this hands-on activity, students investigate different methods—aeration and filtering—for removing pollutants from water. Pour the remaining salt water into a saucepan. Pour the water into the bottle with its top cut off. Place it in the glass funnel. You will see the hydrogen and oxygen bubbling up. Filtration Examples. 8. For the plastic wrap, take the needle and poke 10 holes as small as possible into it. Let it sit and watch what happens as the water begins to flow up the paper. Obtain three 50 ml beakers 2. Instructions for Making a Filter. However, these results were not completely accurate due to mistakes that occurred during the lab. 5. The Earth is covered with water, about 70% of the Earth's surface, but only about 3% of the water on our planet is not salt water. Placing the cone tip into the water. I am constantly on the lookout for ways to take science out of that dry text book and to make it more applicable to a student's daily life. Water filtration methods were examined by using vinegar, oil and laundry detergent. Other important advantage is given by their ability to remove alkalinity and hardness from water. The most common example is making tea. We've tried a filtering experiment using dirty water before, using kitchen roll as the filter. Different methods of separation are used to get individual components from a mixture. During evaporation the solvent evaporates, leaving solid particles behind. When the end of a strip of filter paper is placed in a solution, the paper will begin to absorb the liquid. by. Notice that pepper remains in the coffee filter, while the second jar contains only salt water. This will adhere the paper to the funnel and prevent it from moving during the cold filtration. The water was filtered using a five step filtration process. Make sure students know that in this activity the filtered water is still unfit to drink. 1460 012082 View the article online for updates and enhancements. Procedure. Each group will then share their findings with the class. Fold the coffee filter in half. filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. We looked in the garden for three things that might make good filters, and chose large stones, small stones and sand. Wait several minutes for the water to filter through. For the paper products, create circles with the paper, fold twice and open up to create a cup. DIY Water Filtration System for Science Project Pour swamp water in the 2-liter bottle with a lid. Theory Natural substances are not chemically pure. Compare the results (color, odor, pH, conductivity) among student groups. For example, a teaspoon ot salt dissotve in warm water. Procedure: The first step is to create the filters. In the plastic cup, start by lining the bottom with the coffee filters. In this experiment you will be taking a sample of salt water and add a flow of electricity to it (the electrolysis). Put the lids on both jars and set the jars in a place where they won't be disturbed for a couple days. Punch a hole in the cap of the bottle with a hammer and nail. Conclusion - Filtering Water.
