One morning Ms. Tackle took her class on a walking
field trip of the school and surrounding neighborhood. Along the way the
class passed several puddles of water. They noticed birds and other small
animals drinking from these sources. As they continued around the campus,
they crossed a small creek. When the class turned the corner, one resident
was cutting the yard while another was changing oil. A drainage ditch was
between the two houses. A few blocks later, the students observed a pond
where several people were fishing. It seemed to be a popular spot for picnics
and gatherings because lots of debris could be seen on the banks and floating
in the water. Taking a different route back to the school, Ms Tackle lead
the class around the back of the campus to a well kept "secret."
On the back portion of the campus set a small body of water. It seemed
shallow with no visible water source but it was full of plants especially
algae.
The next day, Ms. Tackle repeated the journey. This
time the students carried small sample jars with them. They were instructed
to collect water samples from different sites as they traveled along.
When the students arrived at the school it was "test" time. Unfortunately,
one of the groups forgot to label the samples. Can you help?
