Exploring the Rate of Plant Growth in Crystals vs. Soil
In this project, measure the rate of growth of a bean seed or young plant placed in a superabsorbent crystal medium to that of a simular plant placed in soil. These crystals canstore water in the soil and then release it as the plant’s roots need it. Learn about the possible application of hydrogel superabsorbent crystals in forestry, gardening, and landscaping as a means of conserving water.
A hydrogel superabsorbent crystal is a long chain of molecules called a polymer that can absorb vary large amounts of water. This ability to hold water makes it an ideal medium for seed germination and plant growth. The research aspect of this science fair project is to compare the rate of plant root growth in water absorbing crystals to that of soil.
