Here's a simple and engaging science project suitable for students in classes 5 to 8. This project involves creating a "Homemade Water Filter." Project Title: Homemade Water Filter Materials Needed: Plastic or glass bottles (2) Sand Gravel or small pebbles Cotton balls or filter paper Coffee filter or fine cloth Dirty water (to simulate contaminated water) Measuring cup Funnel (optional) Rubber band or tape Procedure: Prepare the Bottles: Cut the bottom of one bottle and the top of the other. Keep the bottle caps. Layer the Filter Materials: In the cut-bottom bottle (upside down), layer the materials in this order: cotton balls or filter paper, sand, gravel or pebbles. Each layer should be about 1-2 inches thick. Secure the Filter: Use a funnel or shape a piece of paper into a funnel to make it easier to pour water. Secure the top bottle upside down onto the bottom bottle. You can use a rubber band or tape to ensure a tight fit. Test the Water Filter: Pour dirty water into the makeshift filter and observe the water dripping through the layers. Collect the filtered water in a measuring cup. Observe and Analyze: Observe how the water looks cleaner after passing through the filter. Discuss the role of each layer in the filtration process. Explain the basic concepts of water purification. Present the Project: In your project presentation, explain how water filters work in real water treatment plants. Discuss the importance of clean water and how such homemade filters can be a simple solution in certain situations. This project not only demonstrates a working model but also teaches students about the importance of clean water and basic filtration concepts. It's a hands-on way for students to understand science principles related to water purification. #youtubeshorts #banaen
