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

Metric Conversion: Stair-Step Method Kilo1000 Hecto100

grams liters meters

Deka10

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.

Base Unit Deci0.1

Centi0.01

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 0.001 times.

Milli0.001

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 d) 9 mg = _______g e) 2 mL = ______L g) 4 cm = _______m h) 12 mg = ______ g 3 j) 7.02 mL = _______cm k) .03 hg = _______ dg m) .32 m = _______cm n) 38.2 g = _______kg

c) f) i) l)

8 g = _______mg 6 kg = _____g 6.5 cm3 = _______L 6035 mm = _____cm
