Students exploring biology through the Water theme

After investigating the physical and chemical properties of the water, students are now learning of its role in life: how, apart from our bones and teeth, we are mostly water, how much our life involves liquids (the water we drink, the urine we pee, our sweat, our blood, our cerebrospinal fluid, even our tears); how plants, too, are mostly water (97% in the case of lettuce); and how water is used in photosynthesis. Last week all classes went on their own water monitoring field trip at San Luis Park. This week, the students travel to the hydro-dam, and the middle schoolers go to the Capitol Courtyard to participate in educational activities—including a water-bottle rocket contest—to celebrate Earth Day.
