In this lab experience, students carry out an investigation to determine the effect of road deicers on the germination and growth of lettuce seeds. Specifically, they prepare solutions containing different concentrations of a salt used as a road deicer, and evaluate how the concentration of salt affects the sprouting and growth of lettuce seeds. Based on their results, they argue whether the salt in these solutions is a green choice for use as a deicer.
