Remember the primary purposes of the project:
- To assess the quality of water based on physical characteristics
and chemical substance.
- To look for relationships and trends among the data collect by all
participants.

In your group's Letter of Introduction, you should have
developed a hypothesis. Look at your results and the results from other
school. Do the experimental results support your hypothesis? Why
or why not?
You can use either the "checked" or
"unchecked" data for your analysis. Using the
"checked" data will probably be more important for younger students,
while it actually might be a good experience for older students to determine
if all the "unchecked" data makes sense. How to scrutinize
data is such an important lesson for students to learn. Students are
welcome to use the Discussion Area to question other students about their
results and to provide recommendations to the project leader about what to do
with "questionable" data.
