This
website is maintained by an organization that assesses water quality
and eutrophication. It has volunteer opportunites and many contact
emails. It provides a great deal of information on water quality
assessment techniques and results of studies.
This is a project description for high schoolers about
aquaponics. The
project could take an experimental bent by using aquariums or a
building a large tank, as a school in Maryland did (and posted a
website about)
This is the LCRA
website which provides a listing of all current water assessment and
monitoring. It will allow students to compare their data to that of
other sites and also give them an idea of what kinds of tests can be
used to give information about the health of a water system when they
are deciding which aspects to measure.
Water Quality Testing Equipment and Materials (per
student group)
Hach
or Lamotte water quality testing materials
or meters for each group's workstation (for analyzing DO and pH). Each
group will make up to 5 pH and DO analyses with a meter or two analyses
with chemical reagent kits.
250 ml bottle with a cap
4 - two-inch minnows
(fathead minnows are readily available and tolerant of low oxygen
levels)
75 -100 ml of sandy sediment
75 -100 ml of organic/mucky
sediment
Thermometers (if water
temperature is the selected measure for the student inquiry lesson)
Conductivity pens (if
conductivity is the selected measure for the student inquiry lesson)
Worksheet for each group
(worksheet follows lesson plan).
