Do Deicers Affect Radish Survival?

Do Deicers Affect Radish Survival? | Science Fair Projects | STEM Projects
In this experiment, we'll be testing how different deicers affect the survival of radishes. We'll be using a control group and three experimental groups, and measuring the amount of living radishes two weeks after each deicer is applied.


The hypothesis is that the amount of living radishes will be less if any deicer is applied to them.

Method & Materials

You will need to gather materials, conduct the experiment, and record the results.
You will need 40 containers, 3 packages of radishes, 1 bag of potting soil, 50 grams of rock salt, 50 grams of calcium chloride, 50 grams of magnesium sulfate, a graduated cylinder, a triple beam balance, a fluorescent light with a timer, and 3000mL of tap water.


The results of the experiment showed that magnesium sulfate was the deicer that had the most negative affect on the radishes, followed by salt, being the second most harmful, and then calcium chloride, being the least damaging. The control group still had all 10 radishes standing by the time the experiment was over.

Why do this project?

This science project is interesting because it can help farmers and gardeners to select the deicer least harmful to their plants.

Also Consider

Variations to consider include using more deicers, more plants, and repeating the experiment multiple times.
