These students want to investigate how dirty water can be cleaned using simple natural materials like rocks, sand, coal, and cotton. They built a layered water filter, poured dirty water through it, and observed how much cleaner the water became. This experiment helps show how filtration works and how cleaning and reusing water can help conserve this important resource.
Great experiment! So glad to see young scientists working on real-world problems. Fresh water is so important for our planet. You should all be proud!! Great job!
This is impressive, guys! Your project is very interesting and definitely important. It focuses on a very critical global issue on sustainability and access to clean water. Thank you for conducting this experiment and for beautifully presenting it to us at this science fair.
