“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.” Planet H2O Teacher’s Guide – www.thirteen.org/h2o
This activity allows students to compare the taste of water obtained from different sources in a “blind” taste test and to identify the one they like best.
