  1. Metric System Mr. Martin

  2. What is the metric system? A standard system used by scientists to measure Length, Volume, Mass, Density, & Temperature Based on units of 10 A.K.A. International System of Units or SI

  3. Does this make sense to you?

  4. What is ______? What is ______? What is ______? The amount of matter in an object The amount of space an object takes up The amount of matter in a given volume of an object Jeopardy mass volume density

  5. What is matter? Anything that has mass & takes up space Examples: Solid, Liquids, & Gases

  6. Anyone want to work for me this weekend What are units? • Words used to describe numbers • Example: • meters, liters, grams, %, $…

  7. Meter (m) Metric ruler Metric ruler or graduated cylinder Liter, cm3 = mL Triple-beam balance Grams (g) Tools for mass & volume g/ml or g/cm3 thermometer ºC or K

  9. Date: 9/19/2006 Tuesday Aim: Lab: How can we use the metric ruler to determine the length of an object? Do Now: 1. Take out homework. 2. Put your name & period on the lab Homework: Handout (Section 1-4) BRING IN A CALCULATOR TOMORROW!!!

  10. Date: 9/20/2006 Wednesday Aim: How do we find the volume of a fluid & rectangular object? Do Now: 1. Take out homework. 2. What does the word “volume” mean? Homework: Complete Handouts: Lab Activity: Finding the Volume & Measuring Liquid Volume

  11. The amount of space an object takes up Graduated Cylinder mL

  12. Metric ruler Length x Width x Height (L x W x H) cc cm3 cm m3 1 1

  13. Volume Displacement • Add at least 20 mL of water to graduated cylinder. • Place the object in the water. • Note where the water level rises & then subtract: Final Water Level - Initial Water Level = Volume of the Object

  14. 5 mL 50 mL 55 mL

  15. Length Metric Ruler Liter Volume Gram Triple-beam balance ºC Temperature Mass = The amount of matter in an object Weight = The gravitational pull on the mass of an object

  16. The amount of matter in a given object Triple-beam balance Grams (g) mg

  17. The gravitational pull on the mass of an object Spring Scale Newtons Pounds

  18. mass gravity

  19. The amount of matter in a given volume of an object (how tightly packed together the particles are) Least Greatest D = M/V M V = M/D or M= D(V) D V Graduated Cylinder Triple-beam balance Metric Ruler

  20. g/mL g/cm3 D = M/V D = 150g/V (V = 1 x 5 x 2) D = 150g/10cm3 D = 15g/cm3

  21. D = M/V 3.2 g/mL D = 80.0g/V V = 65.0-40.0 = 25.0 mL D = 80g/25 mL

  22. 44 g 8 cm3 V = M/D V = 44g / 5.5 g/cm3 V = L x W x H 8 cc = L x W x H 8 cc = 2 x 2 x 2

  23. What do we know about density & water? Density of water = 1.0g/mL Anything less than 1.0g/mL FLOATS Anything greater than 1.0g/mL SINKS Density of Ice = 0.9 g/mL (Floats)

  24. Match the Following Densities to the Picture: A. 1.0 g/cm3 B. 2.0 g/cm3 C. 0.7 g/cm3 D E C D. 0.2 g/cm3 A E. 0.5 g/cm3 B
