4 Volume Lab K H da m/l/g d c m Name Part A: Count your drops! Take a guess - How many drops of water will it take to equal 1 milliliter? drops Follow the directions to find the number of drops in 1 milliliter of water, then answer the questions. You will need a small graduated cylinder (25 ml), a beaker of water, and an eyedropper for this section. (1) Fill a small graduated cylinder with 10 ml of water. (2) Count the number of drops it takes to raise the water to 11 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 12 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 13 ml. Record the number in the chart. (5) Calculate your average and round to the nearest tenth. # of drops to 11 ml # of drops to 12 ml # of drops to 13 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? Part B: Water 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. Volume of water before adding marbles Volume of water after adding marbles Difference in volume Volume of 3 marbles Part C: Volume by Formula Use the formula to find the volume of the box. Measure to the nearest centimeter (no decimals) before calculating your answer. Volume = length x width x height x x = T. Trimpe PAGE 4

K H da m/l/g d c m Date: Check out Metric Conversion: Stair-Step Method Kilo Hecto- 100 Deka- 10 Base Unit grams liters meters The Metric System of measurement is based on multiples of 10. Prefixes are used to indicate what multiple of 10 the base unit is being multiplied by. Deci- 0.1 Centi- The prefix Kilo (k) - means 1000 times. The prefix Hecto (h) - means 100 times The prefix Deka (dk) - means 10 times. The prefix Deci (d) - means 0.1 times. The prefix Centi (c) - means 0.01 times. The prefix Milli (m) - means times Milli Base Units will include the gram (g), liter (L), and meter (m) and will have no prefix. To use the Stair-Step method, find the prefix the original measurement starts with. (ex. milligram) If there is no prefix, then you are starting with a base unit. Find the step which you wish to make the conversion to. (ex. decigram) Count the number of steps you moved, and determine in which direction you moved (left or right). The decimal in your original measurement moves the same number of places as steps you moved and in the same direction. (ex. milligram to decigram is 2 steps to the left, so 40 milligrams =.40 decigrams) If the number of steps you move is larger than the number you have, you will have to add zeros to hold the places. (ex. kilometers to meters is three steps to the right, so 10 kilometers would be equal to 10,000 meters) That s all there is to it! You need to be able to count to 6, and know your left from your right! 1) Write the equivalent measurement: (.5 pt each) a) 5 dm = m b) 4 ml = L c) 8 g = mg d) 9 mg = g e) 2 ml = L f) 6 kg = g g) 4 cm = m h) 12 mg = g i) 6.5 cm 3 = L j) 7.02 ml = cm 3 k).03 hg = dg l) 6035 mm = cm m).32 m = cm n) 38.2 g = kg PAGE 6
