Botany Science Fair Project

Electricity and Plant Growth

Electricity and Plant Growth | Science Fair Projects | STEM Projects
Have you ever wondered if electricity can help plants grow faster? In this science project, you will find out if electricity can help radish plants grow faster.


The hypothesis is that radish seeds induced with DC voltages will grow more quickly.

Method & Materials

You will plant radish seeds in two pots, one with an electric current and one without. You will measure the height of the plants and compare the results.
You will need a packet of radish seeds, two plastic pots, two copper rods, soil, a DC 9V battery, a pair of crocodile clips, tap water, and a ruler.


The results showed that the average height of the radish plant in the pot with the electrical stimulation was taller than the radish plants in the pot without. This proves that the hypothesis is true.

Why do this project?

This science project is interesting because it shows how electricity can be used to enhance plant growth.

Also Consider

Consider repeating the experiment by comparing the growth rate using different voltages like DC6V or DC12V. You can also try changing the length of time of exposure to the DC current and compare the plant growth.
