Reading Selections
• Read the passage assigned to your group
on pp.48-52
• Use library and web resources to gather
additional information about your pollutant.
• Be prepared to share your information with
the class in Lesson 9.
• Predict what would happen if your
pollutant was added to one of the class
ecocolumns.

listener. Take notes and write down any
questions you want to ask the groups.
Ecocolumn Observation
• Draw and label the components of your
ecocolumn.
• Record any changes that have taken place
since you joined the aquarium and
terrarium.
• Give one example of interdependence
found in your ecocolumn.
Lesson 10
Planning Pollution Experiments
• How can we test the effects of the
three pollutants using our class
ecocolumns?
• What factors (variables) will we have
to keep the same to have a fair test?
Pollutant Fact Sheets
• Use the pollutant fact sheet to help
design your experiment.
• You may test all three pollutants in
your class or only one.
• Don’t forget to leave one ecocolumn
as your control for comparison.
Record Sheet 10A
• The pollutant we are testing is _____.
• We will make it by mixing ______ with
______ water.
• We will add _______ dropperfuls to
our experimental ecocolumn _____
times per week.

• To make our experiment a fair test,
we will not change these factors:
Record Sheet 10A
• In our daily observations, we will look
for these conditions:
• We predict that our ecocolumn will
show these changes to the plants and
algae after adding the pollutant:
