“Bottled water is a $50 billion-a-year industry worldwide, and people in the United States consume more bottled water than people in any other country. How is it different from what comes out of our taps? Is it really tastier, fresher and healthier – or is that just the advertising hype? The quality of tap water varies depending on where you live, and you can check on the EPA’s Web site to find out if your community’s water meets national standards. For most of us in the United States, tap versus bottled water is a personal choice.”

    SC2015 (9-12) Biology
    5. Plan and carry out investigations to explain feedback mechanisms (e.g., sweating and shivering) and cellular processes (e.g., active and passive transport) that maintain homeostasis.
    a. Plan and carry out investigations to explain how the unique properties of water (e.g., polarity, cohesion, adhesion) are vital to maintaining homeostasis in organisms.
    SC2015 (9-12) Biology
    8. Develop and use models to describe the cycling of matter (e.g., carbon, nitrogen, water) and flow of energy (e.g., food chains, food webs, biomass pyramids, ten percent law) between abiotic and biotic factors in ecosystems.
    SC2015 (9-12) Earth and Space Science
    13. Analyze and interpret data of interactions between the hydrologic and rock cycles to explain the mechanical impacts (e.g., stream transportation and deposition, erosion, frost-wedging) and chemical impacts (e.g., oxidation, hydrolysis, carbonation) of Earth materials by water's properties.
    SC2015 (9-12) Environmental Science
    9. Develop and use models to trace the flow of water, nitrogen, and phosphorus through the hydrosphere, atmosphere, geosphere, and biosphere.
    SC2015 (9-12) Environmental Science
    10. Design solutions for protection of natural water resources (e.g., bioassessment, methods of water treatment and conservation) considering properties, uses, and pollutants (e.g., eutrophication, industrial effluents, agricultural runoffs, point and nonpoint pollution resources).*
