different concentrations of salt water effect plants. The test that will be performed will prove which concentration will have the worst effect. The hypothesis is that by measuring the plants growth each day‚ the largest concentration of salt will harm the plants the most. First‚ the plants were purchased and the water was prepared with the salt concentrations. Second‚ the plants were watered each day with the different concentrations of salt.
