Fungi Science Fair Project

Acid Rain and Lichens

Acid Rain and Lichens | Science Fair Projects | STEM Projects
In this experiment, we'll be looking at the effects of acid rain on different types of lichens. We'll be using vinegar and water to simulate acid rain and see how the lichens respond.


The hypothesis is that acid rain will have a negative effect on lichens.

Method & Materials

You will order two sets of lichens, place each sample into its own glass jar, and mist them with either water or an acid solution. You will then observe the lichens and record your observations.
You will need two sets of lichens, two spray bottles, Dannon bottled water, vinegar, Saran wrap, and a rubber band.


The results of this experiment showed that the lichens exposed to the acidic solution did not mature nearly as well as the control lichens. The fruticose and foliose lichens exposed to the acid solution grew flat and short, while the crustose lichens grew well in comparison.

Why do this project?

This science project is interesting because it shows how lichens can be used as bioindicators to measure the health of an environment.

Also Consider

Variations of this experiment could include testing different concentrations of acid solution or testing different types of lichens.
