Students review metric units of mass/weight and the relative size of items that match the weights. They estimate the mass of a number of items before using a balance scale to find the actual measurement. Also, the classify the type of matter that is being held in film cannister. Finally, they calculate and graph the densities of the substances. Full Review »
