Designing a Controlled Experiment
Farmers in the central valley of California have become increasingly concerned about the build-up of salt in the soil and water. Farmers know that small amounts of salt in the soil and water will not adversely affect the germination and growth of their crops. But as the salt concentration increases, negative impacts occur. Eventually salt concentration may become so great that seeds will no longer germinate.
These farmers want your “company” to do the research and present them with a report that show how increasing salt concentrations will affect the germination of their seed crops. They need to know the relationship between salt concentration and the percent of seeds germinating as well as the average growth.
