Zoology Science Fair Project

Ants and Soil Fertility

Ants and Soil Fertility | Science Fair Projects | STEM Projects
In this experiment, we'll be looking at how ants can help plants grow faster. We'll be using radish seeds, two plastic pots, soil, ants, water, and a tray. We'll measure the height of the plants in each pot and compare the results.


The hypothesis is that the presence of ants in soil will help plants grow better and faster.

Method & Materials

You will fill two pots with the same amount of soil, place five radish seeds in each pot, add 50 black ants to one pot, and place both pots in a place with adequate sunlight and air ventilation. You will water the plants daily and measure their height every day.
You will need one packet of radish seed, two plastic pots, enough soil to fill two pots, 50 black ants, water, one tray, and a ruler.


The experiment showed that the radish plants in the pot with ants had grown taller than the radish plants in the pot without ants. The presence of the ants in the pot had helped to provide a better environment for the radish seeds to germinate and grow faster.

Why do this project?

This science project is interesting because it shows how ants can help plants grow faster.

Also Consider

To further explore this experiment, you could try repeating the experiment with more ants or with earthworms instead of ants. You could also consider repeating the experiment with a variety of other plants or more plants to obtain more accurate results.
