Join the See for Yourself Club and learn about drinking water, its source, testing, health impact, pipes, water filters, story creation, and movie-making. Start with a survey to assess your knowledge. Understand the drinking water delivery system and its components. Explore the water cycle and how water reaches us from Lake Huron. Discover the role of people in the system. Experiment with pH and water chemistry. Let's dive into the fascinating world of drinking water!

See for Yourself! What’s in Your Water? Session 1: Drinking Water and Where it Comes From
What is the “See for Yourself” Club About? • Session 1 –drinking water and where it comes from • Session 2 – testing to see what’s in your water • Session 3 – water and your health • Session 4 – pipes and related careers • Session 5 – water filters • Session 6 – creating your story and film-making • Session 7 – editing your movie • Session 8 – celebrating and watching your movies
Let’s take the starting survey! • This survey will help us understand what you know about drinking water and think about environmental issues at the start of the lessons. It is not a test.
What is the “drinking water delivery system”? • It is a system that moves and cleans water so that water comes to people (usually in buildings) and is safe enough to use for drinking, cooking and more. • The drinking water delivery system makes it possible for water to reach people at home, school, work, businesses (like restaurants) and other places like community centers and places of worship. • The system is made up of water, pipes and people.
The drinking water delivery system is… • Made of 3 components: • Water • Pipes • People • A closed-loop system • Complex and changing
Watershed Map – Flint River Watershed Above: The Flint River as we see it in our daily lives. Left: Aerial view of the entire Flint River Watershed. The land of the city of Flint includes 6 sub-watersheds, or branches, of the Flint River, including the lower main branch and Gilkey Creek.
What Are The 3 Components of the Drinking Water Delivery System? • Water • Pipes • People
People • People interact with the water system as: • Users, consumers (you, me!) • Builders and maintainers • Testers and monitors • People who pay for, and plan for, the future
Vocabulary – Pipes & Infrastructure • Water source • Water treatment plant • Water mains, water main breaks • Drains & sewers • Fire hydrants • Service lines (public and private components) • Curb stop • Plumbing and fixtures in homes, businesses, schools • Water pressure, Residence time of water in system • Point of Use (POU) filters
A “Curb Stop” Have you ever noticed a curb stop in your yard? It’s how you know where the service line to your home is buried.
Raw vs. Refined Water • “Raw water” is straight from the natural source • “Refined water” results from the treatment of raw water to remove: • Biologic agents: Bacteria, viruses • Disinfectants are added at treatment plant to protect us from biologic agents in water • Contaminants • Arsenic, Lead, Copper • pH (scale of acid-neutral-base)
Water Chemistry: Dissolving Stuff (Metal, etc.) in Water See for yourself: let’s make sugar dissolve in water!
pH and Dissolving in Water: See for Yourself! 3 Experiment Stations (fill out observation worksheet) 1) Use a strip of pH paper to test the pH level in each container. • Dip an end of the pH paper into the container and compare the resulting color to the pH spectrum provided in the kit 2) Write your hypothesis about what will happen to nails that are kept over weeks in jars of vinegar (acidic, low pH), water (neutral pH) and bleach (basic, high pH). 3) See how sugar dissolves in water when you stir it in.
Remember: What are the 3 Water System Components? • Water • Pipes • People
