What I Can Do In these activities, you will investigate Newton's Law of Gravitation. You will experimentally investigate the fact that the acceleration of an object due to gravity is independent of its mass. Materials: Several objects of different masses and sizes, such as pencils, crumpled piece of paper, coins, plastic bottle cover. Make sure they are not breakable! Procedure: Record your observation in a separate sheets of paper 1. You will drop various objects to the floor to see if they will fall at different rates. Record your observation 2. Drop a pencil and crumpled piece of paper. Make a repeatable trial for your observation. Which one fell faster? Explain 3. Drop a coin and plastic bottle cover. Make a repeatable trial for your observation. Which one fell faster? Explain 4. Standing on a chair drop the pencil and coin. Make a repeatable trial for your observation. Which one fell faster? Explain 5. From your observation make a conclusion. Assessment for this Activity Points Description A. Learner is able to predict the motion of objects falling to the ground. B. Learner is able to make repeatable measurements of falling objects. C. Learner able to thoughtfully consider the initial predictions and revise them, if in correct. D. Learner is able to correctly conclude that mass has no effect on acceleration 3 Learner achieves the first three objectives above. 2 Learner achieves the first two objectives above. 1 Learner achieve only the first objective. 0 Learner achieves none of the objectives above
