Students learn about the differences between types of water (surface and ground), as well as the differences between streams, rivers and lakes. Then, they learn about dissolved organic matter (DOM), and the role it plays in identifying drinking water sources. Finally, students are introduced to conventional drinking water treatment processes.
Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math (STEM) educational standards.
All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standard Network (ASN), a project of JES & Co. (www.jesandco.org).
In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; within type by subtype, then by grade, etc.

Lesson Background and Concepts for Teachers
|aquifer:||Underground storage unit for water.|
|coagulation:||Process in drinking water treatment during which chemicals are added to the water that make dirt and particles stick together.|
|disinfection:||Process in drinking water treatment during which chlorine is added to the water before it flows to taps.|
|disinfection byproduct:||Formed when chlorine is added to water with high DOM.|
|dissolved organic matter (DOM):||Result of decomposition of plants and animals in a body of water.|
|erosion:||The process by which the surface of the earth is worn away by the action of water, glaciers, winds, waves, etc.|
|filtration:||Process of running water through a filter to make it cleaner.|
|floc:||When particles group together into one larger particle.|
|groundwater:||Water that infiltrates through soil into the ground.|
|lake:||Relatively still, large body of water that has land on all sides.|
|river:||Flowing body of water that has a destination (another river, lake, ocean).|
|sedimentation:||Process in drinking water treatment where the clumps of particles formed in coagulation settle to the bottom of the tank.|
|stream:||Flowing water that has defined bed and banks.|
|surface water:||Any water located on Earth's surface.|
- A Matter of Leaching - Students design and build simple water filters. Then, they test their filters using dirty water.
