Measurement Review/Refresher

Master measurement! Review metric & customary systems, conversions, and density.

Measurement Systems Directions:Sort the information into the correct system. Metric System Customary System Also known as the International System of Units (SI) Also known as US Standard Units Length is measured in meters in this system Length is measured in feet in this system Volume is measured in liters in this system Volume is measured in ounces in this system Mass is measured in grams in this system Mass is measured in pounds in this system Most countries use this measurement system The United States uses this measurement system True or False: Measurements provide a reference so that people can communicate distance, time, weight, cost, size, etc. True False Metric Conversions "Adding a prefix to the base unit (meters, liters, grams) gives information about the unit's relationship to that base unit."**Remembering the acronym for the metric ladder will help you answer the questions below.** Directions: Fill in the blanks with the correct letter, prefix, or number using the ladder picture found above. A= Kilo = 1000B = Hecto= 100C = Deka = 10D = Deci = .1 (1 = Centi= .01 (1 = Milli = .001 (1 Measuring Length Identify the measuring tool used to measure length in the metric system. Triple Beam Balance Metric Ruler Graduated Cylinder Use the tool above to determine the length of the line in centimeters. 2.6 cm 2.7 cm 2.8 cm Use the tool above to determine the length of the line in millimeters. 28 mm 27 mm 26 mm Directions: Match the following measurements with their correct conversion. Use the ladder method to get your answer. 1000 mL 1 L 14 km 14,000 m .109 kg 109 g 160 cm 1,600 mm Measuring Matter Directions:Sort the information into the correct category. Mass The amount of matter (solids, liquids, gases) in an object Measured in the units grams (g) Measurement Tools: Digital Scales Triple Beam Balances Volume The amount of space an object takes up Liquids Irregular objects are measured in the units L or mL ; Regular objects in the units cm3 Measurement Tools: Graduated Cylinders Metric Rulers Density The amount of matter in a given space Measured in the units g OR g Formula to calculate is D=M Applying Measurement Skills Directions: Measure the matter in the pictures below using the correct methods, formulas, and units.

Calculate its density and choose the correct answer from the options below. .5 g 2 g 18 g Would the rock sink in water or float in water? (the density of water is 1 g Sink Float True or False: A large empty cardboard box would have a higher density than a small full cardboard box because it's bigger. True False
