摘要
PURPOSE: A leveling experiment learning tool is provided to perform accurate leveling experiment by marking a numerical part and a graduated ruler on the upper surface of a horizontal plate in order to accurately guide the location of a weight placed on the horizontal plate. CONSTITUTION: A horizontal plate(20) forms a magnetic layer(31) on the upper surface as same length. The horizontal plate forms a numerical part(22) and a protractor(40). The protractor is formed on the center of the horizontal plate. A weight is placed on the numerical part of the horizontal plate. A graduated ruler is marked at one side of the numerical part. A handle part(60) is formed on one side of the horizontal plate or a head part of a supporting stand in order to rotate the horizontal plate.
