How do different types of materials filter contaminants out of our water to make it safe for drinking.
Your hypothesis was proven true. Congratulations!
Dear Student, this is a very well executed project! Your ability to design an experiment, make meaningful measurements, observations and data analysis is remarkable.
I like that you used glitter as your material to be cleaned from the water. Microplastics are a big concern for water purification. Your experiment shows how to effectively remove them. Keep sciencing!
You did an excellent job testing how different materials filter dirty water, and your observations and data were clear and consistent across all three trials. Your explanation of why sand worked best shows strong scientific understanding and using glitter as a contaminant was a creative choice that made the results easy to see. To make your project even stronger next time, you could measure flow rate with a timer or try building multi‑layer filters like real water treatment systems. Overall, this is an impressive and well‑designed investigation. Great work!
