The problem of this project is what is the effect of different concentrations of salt water on the growth of bean plants. The hypothesis for the experiment is that the beans will not germinate and grow as well using saltwater as opposed to freshwater. The germination of a seed is the carrying on of growth of the embryo plant inside the seed. Seeds need water and oxygen to germinate, so they are best started in a light, loose soil that will not compact, get soggy, or crust over. Free flow of water and air are a must. Any disturbances on the plant may cause a negative effect on the plant growth. Plants need water and light to carry out the process of photosynthesis. Photosynthesis is the process by which plants use the energy from sunlight to produce sugar. To conduct this experiment first, plant bean seeds in different pots, and then place the pots in a place where each pot can get the same amount of water. Next, water half of the pots with 300 ml of saltwater, and water the other half of the pots with 300 ml of freshwater. Measure the sprouts and take pictures everyday. . Observe the beans for days. Record the sprouts' average growth every day. Form charts and graphs to show data.
There are many processes and cycles that a plant must go through for it to grow into a mature and healthy plant. The first process that a plant goes through is photosynthesis. Photosynthesis is the process in which conversion of energy from light into chemical energy. The process happens in green plants and photosynthetic bacteria during biochemical reactions.
