Acerca de este recurso...

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.Ahydrogel superabsorbentcrystal is long chain of molecules called apolymer, 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.Placing a plant seed or the roots of a small growing plant into a container of these crystals allows water to be absorbed by the plant’s roots as it is needed. These crystals function similar to hydroponics, which is the growing of plants in water instead of soil. The difference between the two activities is that for hydroponics to be successful, the water must be enriched with nutrients and sometimes oxygenated. Also, the plants must be placed in some type of inert medium like sand, vermiculite, or sawdust to provide mechanical support in order to anchor the roots. The physical structure of the crystals used in this science fair project serves as the anchor, soexternal support is not necessary.
