Botany Science Fair Project

Magnetism and Radish Growth

Magnetism and Radish Growth | Science Fair Projects | STEM Projects
Do you want to know if magnets can affect the growth of radish seedlings? In this experiment, you will use magnets, potting soil, and radish seeds to find out if magnets can affect the growth of radish seedlings.


The hypothesis is that the stem of each plant will be attracted to the magnet.

Method & Materials

You will gather materials, place magnets in the pots, plant the radish seeds, water the plants, and measure the growth of the plants.
You will need clay pots, a light reflector, permanent magnets, potting soil, radish seeds, a grow light, a carpenter's level, and a measuring cup.


The results of the experiment showed that magnets do have an effect on the growth of radish seedlings, but the method used to measure them did not show this. The magnet had an effect on the plants because they were all facing the middle where the magnet was placed, but the roots did not change significantly from pot A and B to pot C.

Why do this project?

This science project is interesting because it explores the effects of magnetism on the growth of plants, which is something that is not often studied.

Also Consider

Variations to consider include using different types of magnets, different types of plants, and different types of soil.
