001314-035 TSAI, Jau-Ann 2 Jau-Ann Tsai Rooney IB Biology HL II 12 Mar. 2010 Bean Plant Lab Research Question: What is the effect of soil salinity on plant growth? Background information: Plants can tolerate certain levels of soil salinity, but excess soil salinity will stunt plant growth. The buildup of salts around the plant root hinders the plants from drawing water from the soil. It takes more energy for the plant to draw water from the surrounding soil when soil salinity is high. This decreases the amount of water the plant obtains and therefore stunts plant growth. Variables: Independent- Salt concentration Dependent- Height of plants Control- Time Materials: Bean plants Light Saltwater (0.2 M, 0.6 M, 0.8 M, 1.0 M, 2.0 M) Ruler Containers Labels Soil 100 mL Graduated Cylinders
