Section Date Student Name Report on Laboratory Experiment “Measurements and Unit Conversions” LABORATORY ACTIVITIES: 1. Measuring length: la Using your body while pacing: This is a quick and easy method in the absence of another instrument. 1. Count how many steps it takes you to cover the 50 ft distance marked on the hall’s floor. hamber of feet 2. Calculate your step size (p e sumber of steps). 3. Count how many steps it takes you to go from one end to the other end of the chalkboard. 4. Calculate the length of the chalkboard (Length (number of steps). (your step stre)). of steps for 50 ft Determination of length by pacing your step size # of steps for board (ft/step) (step) Length of board (step) 1b. Using a British measuring tape or ruler: Measure the length , width Wand height H of the shoebox shaped object and record them in inches plus fractions of an inch. Transform them to decimal format. Dimensions of shoebox shaped object measured with ruler Format length L width W height H In inches and fractions In decimal inches format (show your work)

1c. Using a metric (SI) measuring tape or ruler: Measure the length L, width Wand height H of the shoebox shaped object and record them in centimeters plus millimeters. Transform them to decimal format. height H Dimensions of shoebox shaped obiect measured with ruler Format length L width W In centimeters and millimeters In decimal centimeters format (show your work) 2. Calculating the volume of an object: 2a. Using the geometrical formula for the volume of the object: Calculate the volume of the shoebox shaped object. The values of L. W. and H were previously measured. V=LxWxH Unit to use Volume Show work below cm 2b. Using a graduated cylinder: 1. Put some water into the graduated cylinder. Record the volume indicated by the level of water. This is the volume of water. 2. Fully submerge the metal object provided to you into the water. Record the volume indicated by the level of water. This is the volume of water plus metal object. Content of graduated cylinder Volume (mL) water water plus metal object V(metal object) = V(water plus metal object) – V water Unit to use Volume Show work below mL
