Experiment 1: Metric Measurement Lab In this experiment, you will learn to make measurements using the metric system. Procedure Length of Materials 1. Use the centimeter ruler to measure the items listed in Table 3. Remember to show your work required to convert from the different units. Take pictures of your measurements; this should be submitted as part of your lab assignment Mass of Materials 2. Use the scale to determine the mass the following materials. Place your measurements in Table 4. Be sure to check the unit on the scale to verify that you are measuring in grams (g) ​not ​oz or ct. Remember to show your work required to convert from the ©eScience Labs, LLC 2015 different units. Take pictures of your measurements; this should be submit as part of your lab assignment. Volume of Materials 3. Use the 10 mL graduated cylinder to measure the following volumes. Record your data in Table 5. Remember to show your work required to convert from the different units. Take pictures of your measurements; this should be submitted as part of your lab assignment. ©eScience Labs, LLC 2015 Table 3: Length of Materials Centimeters (cm) Millimeters (mm) Kilometers (kg) 0.01905 meters​ 1.9 cm​ 19.05 mm 1.905x10^-5 0.762 m 76.2cm 762 mm 7.62 x 10^-4 Material Meters (m) Diameter of penny Height of lab counter Width of the textbook Length of the room 0.219 m 21.9cm 219mm 2.19 10^-4 2.5 m 250 cm 2500 mm Material Grams (g) Centigrams (cg) Milligrams (mg) Kilograms (Kg) Mass of a penny 2.5g 250 cg 2500 mg 2.5x10​-3​ kg 2.58 g 258cg 2580mg 2.58 x 10​-3​kg x 0.25 Table 4: Mass of Materials Mass of empty 10 mL graduated cylinder Mass of 10 mL graduated cylinder with 10 mL water Mass of a pencil 36.5 g 8 kg 3650 cg 800 cg 2580000 mg 8000mg 0.0365 8 x 10 -3​​ ©eScience Labs, LLC 2015 Table 5: Volume of Materials Volume Liters (L) Centiliters (cL) Milliliters (mL) Kiloliters (kL) 2 mL 0.002 0.2 2 0.000002 5 mL 0.005 0.5 5 0.000005 6 mL 9 mL 0.006 0.009 0.6 0.9 6 0.000006 9 0.000009 Post-Lab Questions 1. In the metric system what unit of measurement is used for volume? 2. Describe the table that you measured and how the measurement was conducted. 3. Why were you asked to use a 10 mL graduated cylinder to measure volume instead of a 250 mL beaker? 4. Describe the room you measured and how the measurement was conducted. ©eScience Labs, LLC 2015 ©eScience Labs, LLC 2015
