  1. Measurement Review

  2. What is the definition of volume? The amount of space an object takes up. What is the name of the instrument used to measure the volume of a liquid? Graduated cylinder

  3. How is the volume of a liquid measured? Units? Use a graduated cylinder. mL or L How is the volume of a regular solid measured? Units? length x width x height cm3

  4. 2cm 5cm 3cm • 3 x 2 x 5 = • 30cm3

  5. Measure the volume of the liquid to the left. Measure the volume of the liquid to the right. 21mL 67mL

  6. Measure the volume of the liquid to the left. Measure the volume of the liquid to the right. 2mL 49mL

  7. What is the volume of this toy dinosaur? 0.8mL (5.6mL – 4.8mL) 2. What is the name of this method? displacement

  8. What is the definition of mass? The amount of matter in an object. 2. What is the name of the instrument used to measure mass? triple beam balance 3. What are the units used to measure mass? grams

  9. Mass = 137.4 gm

  10. Temperature: When using the Celsius scale: water freezes at 0°C water boils = 100°C human body temperature is 37°C

  11. Determine the cm length at each letter to the nearest tenth. Determine the mm length at each letter to the nearest whole number. 11.3cm 10.3cm 12.5cm 13.2cm 14.3cm 11.7cm 113mm 117mm 125mm 132mm 143mm 103mm

  12. 0 1 2 3 4 cm What is the length of the object in millimeters? Centimeters? 8mm .8cm

  13. 0 1 2 3 4 cm What is the length of the object in centimeters? Millimeters? 2.8cm 28mm

  14. What is density? Mass per unit volume 2. How is the density of an object measured? Density = mass/volume

  15. What is the density of one cup of water? 1g/mL 2. What is the density of half a cup of water? 1g/mL

  16. 1. What is the density of a 100gram object with a volume of 20 milliliters? 5g/ml 2. The object above was cut into three pieces. What is the density of one of those pieces? 5g/ml

  17. Explain why an object placed in a glass of water floats. The object has a density less than the density of water (1g/ml).

  18. Explain why an object placed in a glass of water sinks. The object has a density more than the density of water (1g/ml).

  19. Below is a list of the densities of different object. Will each one float or sink in water? • 0.38 g/cm3 • 1.7 g/cm3 • 1.2 g/cm3 • 0.99 g/cm3 • 100 g/cm3 float sink sink float sink

  20. mm, cm, m, km g cm3 mL or L g/cm3 g/mL

  21. Identify the meaning of each prefix. Kilo = Centi = Milli = 1000 .01 .001

  22. 1 kilometer (km) = meter • 1 centimeter (cm) = meter • 1 kilogram (kg) = grams • 1 milligram (mg) = gram • 1 kiloliter (kl) = liters • 1 centigram (cg) = gram • 1 millimeter (mm)= meter 1000 0.01 1000 0.001 1000 0.01 0.001

  23. CONVERSIONS KILO (k) HECTO (h) DECA (da) METER (m) DECI (d) CENTI (c) MILLI (m)

  24. Complete the following conversion: • 21hm = ____d • 21. 0 0 0 = 21000d

  25. Complete the following conversion: • 12cm = ____m • 12. = .12m

  26. Complete the following conversion: • .45m = ____ km • .45 0 0 0 = .00045km

  27. Complete the following conversion: • 6.3daL = ____ cm • 6.3 0 = 6300cm 0
