Environmental Pollution Science Fair Project

Investigating River Pollution

Medium
Investigating River Pollution | Science Fair Projects | STEM Projects
We're going to take samples of water from a river upstream and downstream to see if the water downstream is more polluted. We'll use a pH paper, a turbidity meter, and a freshwater test kit to measure the acidity, turbidity, ammonia content, and nitrate content of the water samples.

Hypothesis

The hypothesis is that the water sample taken upstream (where there is less human activity) will contain less pollutants compared to the water sample taken downstream.

Method & Materials

You will collect 5 samples of the river water upstream and 5 samples of the river water downstream. You will then use a pH paper, a turbidity meter, and a freshwater test kit to measure the acidity, turbidity, ammonia content, and nitrate content of the water samples.
You will need 10 empty resealable bottles, transportation, pH paper, a turbidity meter, a freshwater test kit, and a marker pen.

Results

The results showed that the acidity of the downstream water samples was higher than that of the upstream water samples. The turbidity, ammonia content, and nitrate content of the downstream water samples was also higher.

Why do this project?

This science project is interesting because it shows how human activity can affect the environment. It also shows how important it is to keep our rivers clean.

Also Consider

Consider testing the quality of the water in lakes and ponds located at different distances from urbanized/densely populated areas. Also consider testing the water samples from different rivers.
