To practice the scientific method, students tested to find the soil combination that would hold the most water.
First, students observed garden soil, peat moss and sand. Next, they make 4 different combinations of the soils and poured water into a paper cup with holes in the bottom to collect water in a beaker. Students then compared their results and formed a conclusion about which combination would be best to use for your house plants.
A great start to learning about earth science for these 6th graders!
