8. Measuring Volume Lab Part 1: Count your drops! Follow the directions to find the number of drops in 1 milliliter of water, then answer the questions. You will need a graduated cylinder (100 mL), a water bottle, and a dropper for this section. 1. Fill a small graduated cylinder with 20 mL of water. 2. Count the number of drops it takes to raise the water to 21 mL. Record the number in the chart. 3.Leave the water in the graduated cylinder and count the number of drops it takes to raise the water to 22 mL. Record the number in the chart. 4.Leave the water in the graduated cylinder and count the number of drops it takes to raise the water to 23 mL. Record the number in the chart. 5.Calculate your average and round to the nearest whole number.

9. Volume Data Table Part 1: Count your drops! # of drops to 21 mL # of drops to 22 mL # of drops to 23 mL Average Based on your average, how close were you to your guess? __________ Based on your average, how many drops would it take to make 1 liter? __________ Hint: Did you include the proper unit in each of your measurements? If not, go back and label them.

10. Measuring Volume Lab Part 2: Volume Displacement Follow the directions to find the volume of three marbles using water displacement. 1.Add 20 mL of water to a 100 mL graduated cylinder. Record this amount in the chart. 2.Add three marbles to the cylinder and measure the volume. Record this amount in the chart. 3.Find the difference between the two measurements and record in the chart. The difference between the two measurements will be the volume of the three marbles.
