Students participate in a science lab to determine the pH of three different soil samples. Students conduct an experiment by creating a question, a hypothesis and then an investigation of soil samples. Then they compare colors apprearing in test tubes with those on the pH color chart to determine the soil's acidity, neutrality or alkalinity. Full Review »
