A list of the materials which are contained in each Operation Water Biology kit. Lesson 1 bag: 6 total chlorine test strips, 6 plastic cups, 6 empty 5mL vials, One tube of Granular Activated Carbon (GAC)
These are the directions for performing the tests that you will refer to each time you need to determine the total chlorine, free chlorine or ammonia concentration of a water sample.It is important to follow these testing instructions very closely. Extra test strips are not provided so you will need to make each one count.
Students will expand their understanding of chlorine demand by participating in an experiment. Students will learn about the Guidelines for Canadian Drinking Water Quality guideline for total chlorine. Students will learn how to perform calculations involving concentration, volume and dilution factors.
