Instructions:
For this project, you will engage in a variety of activities that
follow the scientific method beginning with making initial
observations and developing a hypotheses (see
Student Guidelines for the using the Scientific Method for more information).
- Introduce the Project: The main purpose of this project is to
make a general determination about the water quality of a fresh
water body, compare the data collected by all project
participants, and look for relationships, trends, similarities,
and differences. To do so, you will:
- Conduct a variety of water sampling tests to analyze physical
and chemical substances commonly found in a fresh water body
- Compare your findings with other participating classes.
- Initial Observations:
- Select a fresh water body such as a river or stream close to your community where you would like to conduct the
fresh water sampling tests.
- Make an initial visit of the site. If that is not possible, it
is recommended that you take a picture or several pictures of the
fresh water body and show them to the class.
- Develop Hypotheses based on the following questions:
(this can be done as a whole class activity, as teams, or as
individuals)
- Do you think your water is of good, or poor quality? Why?
- Do you think the water quality will be better in some areas
of the world or worse? Why?
- Are the organisms found in the water the same all over the
world? Why or why not?
- Once you have written down your hypotheses, continue to the
next activity.
