Name ______________________________________________________________________ Room _____________ Measuring Volume Class Notes MEASURING VOLUME Volume is the amount or how much space an object takes up. Milliliters (mL) is the unit measure for liquid volume. The beaker often has lines every 5 mL (milliliters). Meniscus is the curved shape of the waterline. To measure the volume of a liquid, scientists pour the liquid into either a beaker or graduated cylinder. The surface of the liquid curves up the sides of the beaker and graduated cylinder. Measure the volume of the liquid from the bottom of the curve. See which line from the side of the beaker is closest to this level. What is the volume of water contained in each of these two beakers? What is the volume of water contained in the graduated cylinder? A. _40_ mL __36.5__mL B. _75__ mL What is the volume of water contained in the graduated cylinder? A graduated cylinder contains 20.0 mL of water. After a rock is placed in the cylinder, the level rises as shown below. What is the volume of the rock? __43__mL __14___cm3 The diagram shows two containers, A and B. Container A contains 150 milliliters of water. Container B is empty. The diagram shows two measuring containers, A and B. Container A contains 10 milliliters (mL) of a liquid. All of the liquid from container A is poured into container B. Shade container B in the diagram above to show the volume of the water in container B after it was poured from container A. The diagram shows four identical marbles and a graduated cylinder containing 43 mL of water. A student puts two marbles in the cylinder and the water level rises from 43 mL to 45 mL. The student then puts the other two marbles in the graduated cylinder. 1. What will the water level be when all four marbles are in the graduated cylinder? A 43 mL C 47 mL B 45 mL D 49 mL 2. Which property of the marbles causes the water level to rise when they are put in the graduated cylinder? A. color B. shape C. texture D. volume If all of the water from container A is poured into container B, what will happen to the volume of the water? A. It will decrease. B. It will increase. C. It will remain the same. If all the water from container A is poured into container B, which property of the water will change? A. mass B. color C. shape Review Complete the chart by filling in the three shaded boxes with the correct property, tool, and metric unit of measurement.

If the first tick-mark is 20 mL, what is the volume of the liquid in the beaker? A. about 40 mL B. about 60 mL C. about 80 mL D. about 100 mL Use the illustration below to answer questions 6-8. 6. What is this tool called? A. funnel C. graduated cylinder B. flask D. beaker 7. What kind of measurement do you make with this tool? A. length C. temperature B. mass D. volume 8. How many milliliters of liquid are shown? A. 40 B. 43 C. 45 D. 50 The diagram below shows liquid in a container and an empty container. 9. All the liquid is poured into the empty container. Which property of the liquid changes? A. color B. odor C. shape D. volume The diagram below shows a glass of water and a rock. 10. When the rock is placed into the glass, the water level will A. decrease B. increase C. remain the same 11. Which force causes the rock to sink to the bottom of a glass of water? A. gravity B. friction C. magnetism D. electricity 12. Complete the chart by identifying the scientific tool used to measure each of the physical properties listed.
