Activity – Making Measurements I. Wood Block mass = __________ g volume = l x w x h __________ cm l = w = h = __________ cm __________ cm Calculate density = mass volume

II. Water massFC& Water = __________ g __________ g massFC = __________ g mass Water = __________ mL volume = Calculate density = mass volume

III. Measuring Volume - Beakers vs. Graduated Cylinders Measure 100 mL of tap water using a beaker, then transfer and measure with the 100 mL Graduated Cylinder 150 ml beaker __________ mL 250 ml beaker __________ mL __________ mL 400 ml beaker

Most graduated glassware is marked “TC” or “TD.” What do you think “TC” means? What do you think “TD” means? Which glassware (“TC” or “TD”) do you think is more expensive? Why?
