In this activity, students explore methods to treat wastewater by creating a laboratory model that simulates large-scale commercial water treatment methods.
- Kit Aligned to Fundamental Frameworks Concepts ESS3
- Pre and Post-Laboratory Assessments
- Model Simulates Large-Scale Commercial Treatment Methods
- Estimated Class/Lab Time Required: 105 minutes over Three Lab Sessions
- Students Learn How Our Water Is Cleaned
They learn the purpose of each stage of the water treatment process and evaluate how effective each stage is. Students' understanding of the basic framework principle of Earth and Human Activity (ESS3) helps them learn and understand the importance of wastewater treatment.
Pre and post-laboratory assessments and vocabulary words target specific Science and Engineering Practices and common core standards. The teacher guide also contains specific "Did You Know" sections. A student copy master and material for five setups are included. The activity requires 105 over three lab sessions.
Certifications: aligned with all published National Standards.
