Question

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?
Observe the fish
began dying prematurely
since the factory began operations

Answer 1

Explanation:

This investigation should follow the proper scientific method.

Observe the fish that began dying prematurely  since the factory began operations

In any scientific investigation into a problem, observation are first made. This is usually done with our senses and what we perceive around our vicinity. The dying fish in this regard should be properly observed for any kind of color change, smell e.t.c

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

Observations stems inquiry. Proper questions should be asked about the likely reasons why the fishes are dying. Is it the factory? Is there are period of the year when fishes die? Is it climate change?

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

A hypothesis should which is a scientific guess about the problem should be developed. Hypothesis furnishes conduction of experiments. It is made up of the if, then and because part that seeks to predict the problem, effect and the causes.

Collect samples of river  water over a period of  time and test them  for pollutants.

After developing the hypothesis, the experiments should kick start as soon as possible by collecting the river water and testing them.

Analyze the composition  of the water samples.

Analysis will reveal to us if the hypothesis is correct or not.
