Water We Drink for Kids: From Source to Faucet (Grade 4 and 5 Science)

Hi, I'm Luna from DoodleBeez. When you turn on the faucet, clean water flows out. But where does it come from, and how does it get so clean? Let's follow water from its source to your glass.

Drinking water comes from two main sources. Surface water is found in lakes, rivers and reservoirs. Groundwater is stored underground and is pumped up through wells.

Water from nature can carry dirt, leaves and tiny germs we cannot see. So most cities send it to a water treatment plant before it reaches homes.

At the plant, chemicals are added that make small bits of dirt clump together. The heavy clumps sink to the bottom of big tanks. This settling step removes a lot of the mess.

Next, the water flows through filters made of layers of sand, gravel and charcoal. Then a disinfectant, often chlorine, kills germs. Clean water is stored and pumped through pipes to homes.

Clean water takes work, so we should protect it. Keep trash and chemicals out of drains and streams. Save water by turning off the tap while brushing and fixing leaky faucets.

Now it's your turn. Which step in water treatment kills germs? Is it settling, filtering or disinfecting? Pause and try. Disinfecting kills germs, often by adding a small amount of chlorine.

Great job! Remember, drinking water comes from surface water or groundwater. It is settled, filtered and disinfected, and we all help protect it. Practice the water we drink in the Science Lab at doodlebeez.com. See you next time!
