Water Filtration System in Mr. Urla's Class

Last week, Mr. Urla’s Upper School Earth and Space Science class learned about water filtration. They created their own filtration system using gravel, charcoal, sand, and cotton as their filters.
Observing the process and understanding how long it takes for water to be filtered down into our aquifers, our students learned about the importance of having clean water for our ʻĀina.
