Student Water Investigators Classroom Modules

SWI Classroom Modules

Using the skills of a detective, students investigate water properties, explore groundwater and examine the community water cycle. The curriculum and supporting materials are FREE of charge, one per school. Activities are correlated with the Texas Essential Knowledge and Skills (TEKS) standards and designed to fit the 5-E model of instruction. The curriculum is divided into three models. Modules are complementary but not contingent on one another.

SWI Academy

At SWI Academy, students learn about the unique properties of water that make it essential to life on Earth. They become "part of the action" through video segments shown before each investigation. Activities include making observations, exploring the chemical composition of water and investigating properties of water such as density, surface tension and pH. After completing the module, students receive an SWI identification card signifying them as certified Student Water Investigators. (Recommended for sixth grade.)

Groundwater Sleuthing

In the Groundwater Sleuthing module, students become water investigators to explore groundwater. The investigators are called upon to determine the source of groundwater contamination in the fictional city of Rogers Glenn. The module uses innovative flash animation to bring the investigation to life. Investigators collect data, analyze information and draw conclusions to solve the mystery. (Recommended for seventh grade.)


Humans have always built our lives around water. All living things need it. In the AquaCity module Student Water Investigators will explore the water as it moves through a community. They will learn how water is moved from source to consumer, the importance of safe drinking water to a community and how and why used water is treated before it is returned to the environment. At the end of the module, investigators will have the opportunity to find out what it is like to be a water utility by playing "Where's the Water," a role-playing game in which participants face the challenges of providing water for their communities. (Recommended for eighth grade.)
