Finding the Mass of Objects

In this worksheet, students will take everyday objects from the classroom and use balance scales to find the mass.  The students will first describe the object and then estimate the mass.  They will then weigh the object and write down that actual mass.  Finally, they will find the difference between the actual mass and the estimated mass.  Once students are finished they will sort the mass from lightest to heaviest.  The main purpose of this assignment is to have students make estimates and then use actual scales to find the mass.
