My Stream’s Temperatures
– temperature is tested at a variety of places within a field site
Temperature: Air vs. Water vs. More Water
– air vs. water temperature and how the volume of water affects temperature
– activity illustrating pH concept with people as atoms
pH Test #1 – Scaling Common Liquids
– make a pH scale by testing the pH of some common substances
pH Test #2 – Manipulating the pH of a Liquid
– use household substances to create an acidic solution and then change it back to its
pH Test #3 – Rain vs. Surface Water
– measure the pH of the rain in your area to determine if it is acidic; compare the rain
pH to that of a local body of water

Water Chemistry Bingo
– review basic water chemical parameters
Module Resource Guide Information Sections:
General Sampling Information
Instructions on how to collect water samples, what equipment is needed, how to distribute jobs to various students, what tests can be done in the field, which in a laboratory, safety information, and scientific protocols.
Easy to use data sheets specific for the chemical kits in the modules.
Clear instructions are enclosed for each piece of equipment found in the watershed activity module (from the bailer to the test kits). If used, testing results have a better chance of being accurate.
For each chemical parameter that can be tested using module equipment, a background information sheet can be found about it. Great to use as student preparation or for research background.
In outline form and more visual than the information sheets, these highlight key concepts for each of the chemical parameters. Great to use with the test kits – have students read them over during breaks in the test kit procedures. Great for handouts in the classroom or visual aids.
Articles of Interest
About water parameters or chemical testing of waterways in general.
Data Analysis Information
For teachers that want their students to graph, interpret, analyze data, this section is helpful. It outlines parameter relationships and the effects on water quality that can be investigated.
General Activity Information
A list of module activities and an explanation of the activity format (layout).
Specific to the water chemistry theme, these are activities that can be used in the classroom and/or field. Some address specific water parameters, some are more general.
Sources from which module information was obtained. Resources that you can find for further investigations.
