The Effects of Gasoline Fumes on Plants

The Effects of Gasoline Fumes on Plants | Science Fair Projects | STEM Projects
In this project, we'll explore the effects of gasoline fumes on plants. We'll observe how long it takes for plants to die when exposed to gasoline fumes at different temperatures.


The hypothesis is that gasoline fumes cause plants to die, and the longer the exposure to the fumes, the quicker the plants will die.

Method & Materials

You will set up four potted plants in a well-lit area, and cover them with aquariums. You will then expose the plants to gasoline fumes at different temperatures for different lengths of time.
You will need four potted plants of the same size, four transparent aquariums, four ceramic bowls, one liter of gasoline, a thermometer, and a black marker pen.


The results showed that the plants exposed to gasoline fumes for longer periods of time, and at higher temperatures, died more quickly.

Why do this project?

This science project is interesting because it shows how gasoline fumes can have a negative effect on plants, and how temperature can affect the rate of death.

Also Consider

To vary the experiment, you could try to ascertain if certain species of plants are more resilient in the presence of gasoline fumes, or study the effect of gasoline vapor on insects.
