Students in a riverside town discover that the fish in the river are suddenly dying prematurely. They suspect that the fish are dying because a nearby
factory must have started dumping industrial pollutants into the river. Following are some steps that the students can follow to verify whether what
they suspect is true. Arrange the missing steps in the flowchart in the correct order.
Collect samples of river
water over a period of
time and test them
for pollutants.

Analyze the composition
of the water samples.

Develop a hypothesis: The fish
are suddenly dying prematurely
due to the recent release of
toxic industrial pollutants into
the river.

Ask questions: Could the
nearby factory be releasing
pollutants into the water?
