Introduction to Web Quest

We want our students to consider the variety of products they may put into their water and the impact on water quality in the future.

Questions to be considered

What is the fate of the variety of products

that you introduce into the water?

Can the product residue be easily treated or removed?

Is there an impact on the water we drink?

Does this affect humans now or in the future?
