Why do objects with more mass weigh more than objects with less mass? All objects have weight on Earth because their mass is affected by EarthÃƒï¿½Ã¯Â¿Â½Ãƒï¿½Ã‚Â¢Ãƒï¿½Ã‚Â¯Ãƒï¿½Ã‚Â¿Ãƒï¿½Ã‚Â½Ãƒï¿½Ã‚Â¯Ãƒï¿½Ã‚Â¿Ãƒï¿½Ã‚Â½s gravitational force. Because the mass of an object on Earth is constant, the relationship between the mass of an object and its weight is also constant. You will measure the mass and weight of several objects to verify the relationship between mass and weight on the surface of Earth.
This lab provides students with the opportunity to actually see that mass and weight are directly related. To complete this lab a few items are needed: small classroom objects, a spring scale and a balance. I provide a completed data for the absent students. Of course, this lab can be revised to your liking including the items you wish your students to investigate.
