Cauliflower Plant Growth

Easy
Cauliflower Plant Growth | Science Fair Projects | STEM Projects
We're going to explore how different salts affect the growth of cauliflower plants. We'll measure the height and root systems of the plants to see which salt has the biggest effect.

Hypothesis

The hypothesis is that the cauliflower plant watered with Epsom salt will have the shortest growth height and the smallest root system.

Method & Materials

You will split twelve cauliflower plants into four groups, label each group with a different color, and water each group with different solutions.
You will need 45 mL of MgSO4 · 7H2O, 45 mL of NaCl, 45 mL of KCl, and 300 mL of H2O.

Results

The results showed that the NaCl solution was most harmful to the height growth of the cauliflower plants, and the H2O group had the most complex root system.

Why do this project?

This science project is interesting because it shows how different salts can have a big impact on the growth of plants.

Also Consider

Variations to consider: try different concentrations of the salts, or try different types of plants.
