Student Worksheet - Activity 1: Develop a Hypothesis
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 using the following Student Guidelines for the using the
Scientific Method:
Formulate or state the question.
Identify prior knowledge that is related to the question.
Predict what you think the answer to your question might be.
State the hypothesis.
Test the hypothesis by doing an experiment or activity.
Collect data.
Study the data: Look at the postings of other classes. Think about what
their information means
Make conclusions; decide if your hypothesis is correct. What did you learn?
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:
Name of fresh water body: ______________________________
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 ins 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.
