Educational Materials Environmental Educational Materials Environmental Learning Activities
Discover how we impact the quality of our water.

  • Students will explore types of pollution and human impacts to water
  • Modules include in-depth background reading, quizzes, and ideas for lesson extensions that align with NGSS
In the "Earth and Human Activity: Water Quality" kit, students collect water samples from a local environment and test a suite of environmental parameters, including: pH, nitrates, phosphates, oil, and lead. Students are guided through the scientific method and design their own controlled experiments to investigate the effects of nutrient loading on an aquatic system. A teacher demonstration on particle settling time introduces a discussion about particulates in the environment and in drinking water.

Facts About California Proposition 65
Ward’s Science is committed to your safety and compliance with California’s Safe Drinking Water and Toxic Enforcement Act of 1986. As of August 30, 2018 the reporting requirements of this act, more commonly known as Proposition 65 changed. These changes require retailers who do business in the State of California to provide more robust and detailed labeling on items containing certain chemicals known to the State of California to be hazardous. In response, we have added new labels like the one shown below to many of our product packages and catalog descriptions. You may now see these labels on some products and packaging, even if you do not reside in the state of California. The safety and contents of our products have not changed. Our products continue to meet the highest safety standards for your classroom. For more information about California Proposition 65 and how it affects you, visit wardsci.com/prop65.
