Water, Water Everywhere, But....Notes for the Teacher, Report Writing Directions and Experiments.
Provided in this teaching package are materials that clearly and simply unveil the mysteries of water pollution. Materials, written on an approximate seventh-grade level, include: (1) a student reading unit; (2) water quality factors pamphlet; (3) experiments; and (4) teacher's guide to field testing a local waterway. The student reading unit is the basic text, complete with diagrams, question sheets, and examination. The water quality factors pamphlet (written with the assumption that students have no background in chemistry and limited knowledge of mathematics and general science) is a reference unit listing a variety of popular chemical, biological, and physical tests which can be performed on a waterway. In addition, information is given about the environmental effects and toxic limits of each potential pollutant. Simple in-class/field experiments, printed on loose sheets for ease of reproduction, focus on: effects of biodegradable waste on dissolved oxygen; thermal pollution; effects of thermal pollution of fish metabolism; measuring amount of dissolved oxygen in a water sample; determining number of coliform bacteria in water samples; and measuring stream velocity/volume. Teachers notes for experiments, answer keys, a turbidity color chart, and test kit/reagent list are included. All materials are designed for but not limited to grades 7-10. (JN)
