After this experiment, you should have a greater understanding of the scientific method. You can take this knowledge to the next level by designing other experiments pertinent to
environmental sciences. One major environmental concern of our time is soil salinity.
Soil salinity is a measure of salt content in soil and can result in degradation of soils and
vegetation, severely decreasing crop yields. The ions responsible for soil salinity are:
Na, K, Ca2+, Mg²+, and C1. High levels of salt in soil may result from human activities
such as irrigation, land clearing, aquaculture activities, and salting icy roads. Briefly
explain how you would use the scientific method to perform a lab experiment to study the
effects of soil salinity on plant growth. Make sure you use the concepts of experimental
design, hypothesis testing, data analysis, and interpretation of results. It may be helpful to
include the following in your experimental design. You may have to do some online
research for this question.
