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

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.

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.

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

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

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
