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 »

Students identify that they do not have to live on a farm or own a garden to do an agricultural science project. Students research agriculture by using their reading skills and creative thinking. Students identify and analyze how different types of fertilizers affect plant growth and how various treatments change how fast seeds sprout. Students also identify how soil pH affects the pH of water in the soil. Full Review »

Students investigate the pH of certain types of substances and those being used in their project investigation. They use litmus and pH paper, along with pH meter probes to determine whether substances are acidic, basic or neutral. Students construct own pH scale and indicate where each substance tested lies in the scale. Full Review »
