Students are to\u00a0complete pages 16-18 in their Science Notebook as a preparation for their activity on calculating density of small objects.<\/p>\n
Students will practice on six different small objects to determine the mass and the volume\u00a0of each object,\u00a0and then derive the density of\u00a0each object that is based upon\u00a0its mass and volume.<\/p>\n
Note that the volume of objects\u00a0can have\u00a0regular or irregular shapes. If\u00a0the object\u00a0has a regular shape, find the length, width, and height\/depth\/thickness and multiply these three values together. If\u00a0the object\u00a0has an irregular volume (one of these three variables is missing), then use the water displacement method to determine how much of the water is displaced by the object. Then subtract the original volume from the\u00a0new volume of water to get the volume of the object. Once\u00a0the volume and the mass of the object ( “weighing” it on a scale for its mass)\u00a0are determined, then divide the mass of the object by its volume to figure out the value of its density.<\/p>\n","protected":false},"excerpt":{"rendered":"
