Comprehensive School Kit - 8 Tests for 30 Students

With a well planned teachers manual, navigate students through 11 experiments and tests in a format that actively promotes student involvement and class discussion. The PurTest® COMPREHENSIVE SCHOOL KIT contains enough material for 30 students to complete 8 tests each plus 3 tests for the teacher to demonstrate to the class. 

Features:

• Build simple models of the hydrologic cycle and a water well.
  
• Identify how water acquires acid rain. Includes the same bacteria test used by the Centers for Disease Control and Prevention (CDC).
  
• Test for lead in water in 10 minutes. Detects lead down to the EPA-safe standard of 15 ppb (parts per billion).
  
• Identify absence or presence of pesticides based on the EPA standard for safety.
  
• Identify absence or presence of nitrates, nitrites, hardness, pH, alkalinity, chlorine, iron, and copper in 30 water samples.
  

The Comprehensive Kit experiments include the hydrologic cycle, building a well, acid rain and the dilution solution, along with water facts, water usage, monitoring and general water awareness knowledge.
