The Effects of Water on Radish Seeds

Medium
The Effects of Water on Radish Seeds | Science Fair Projects | STEM Projects
We'll be testing the effects of tap water, mineral water, and seltzer water on the germination and growth of radish seeds. We'll measure the height and weight of the plants to see which type of water helps them grow the most.

Hypothesis

The hypothesis is that mineral water will be the best for the germination and growth of radish seeds.

Method & Materials

You will set up three boxes with different types of water, place two radish seeds in each box, and observe the growth of the plants over three weeks.
You will need black plastic boxes with covers, rock wool, mineral water, tap water, seltzer water, air pumps, a plastic cup, pH paper, garbage bags, a thermometer, and radish seeds.

Results

The results showed that the plants were tallest in seltzer water, and the average mass for plants was greatest for those in mineral water. The T-Test showed that the difference between mineral water and tap water was significant, as was the difference between tap and seltzer water, while mineral water to seltzer water was insignificant.

Why do this project?

This science project is interesting because it shows how different types of water can affect the growth of plants.

Also Consider

Experiment variations to consider include testing different types of plants, such as beans or carrots, or testing different types of water, such as distilled water or rainwater.
