Expand the experiment by tying small objects to one end of the pencil to determine how this changes the point of balance. Gravity is pulling the ends down toward the center of the earth, and if the pencil is not properly balanced it will fall off the finger. Students can observe gravity by balancing a pencil on their finger. Simple experiments to test gravity and how it affects the balance of objects will provide experience with observation. Observation Grade school students are just beginning to explore the world of science. Some of these experiments can be replicated by students to learn about the force of gravity and how it relates to the motion of objects on earth. Sir Isaac Newton, rumored to have discovered gravity when he saw an apple fall from a tree, wrote mathematical formulas that proved the truth of experiments previously performed by Galileo centuries earlier. Gravity is defined as the force that pulls everything on earth toward the center of the earth. StartSOLE is a simple inquiry-based approach that can be implemented in a single class period with minimal constraints and serves as an excellent addition or supplement to this lesson.Every time you fall down you’re experiencing the pull of gravity.
