  1. Date: 9/19/2011 Monday Aim: What are metric units of measurement? Do Now: Prepare for quiz (Scientific Method) What is the purpose of the Metric System? Homework: Read pgs 14-21 Answer questions (1, 2, 4, 5) on pg 21 BRING IN A CALCULATOR TOMORROW!!!

  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: 9/20/2007 Thursday 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: 9/21/2007 Friday 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: Have a great weekend!!!

  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. Date: 9/24/2007 Monday Aim: How can we determine the volume of a cube/rectangle & an irregularly shaped object? Do Now: What is the volume of the following objects: Homework: Study for quiz (BRING CALCULATOR) A. B. 2 cm 2 cm cube 5cm 3cm

  14. 24 cm3 18 cm3 4 cm3 56 cm3 36 cm3

  15. 15,000 cm3 3,600 cm3 140 cm3 6,000 cm3 48,000 cm3 3,600 cm3

  16. 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

  17. 5 mL 50 mL 55 mL

  18. 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

  19. Date: 9/25/2007 Tuesday Aim: 1. Take Quiz 2. How can we determine the mass & weight of an object? Do Now: Prepare for Quiz. Homework: Handout (Triple-beam balance)

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

  21. 389.3 g 578.6 g 499 g

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

  23. mass gravity

  24. Date: 9/26/2007 Wednesday Aim: 1. How can we determine the density of an object? (Density Determination Handout)2. Does density change with size? Do Now: 1. What is mass? 2. How do we determine the mass of an object? 3. What are units of mass? Homework: Handout (except #s 5,10,11 & Bonus) BRING IN A CALCULATOR & PENCIL EVERYDAY!!!

  25. 722.9 g 200.5 g

  26. 45.5 g 153.7 g 514.0 g

  27. Date: 9/27/2007 Thursday Aim: 1. How can we use the magic triangle?(Practice Problems)2. What do we know about density & water? Do Now: 1. Take out homework. 2. How do you calculate density? 3. What are units for density? Homework: Study for tomorrow’s Quiz. BRING IN A CALCULATOR & PENCIL EVERYDAY!!!

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

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

  30. D = M/V D = 80g/V V = 65-40 = 25 mL 3.2 g/mL D = 80g/25 mL

  31. 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

  32. Date: 10/3/2011 Monday Aim: 1. What do we know about density and water? Do Now: Brain Pop – Measuring Matter Homework: 1. Study for Quiz tomorrow on Density 2. Study for next Monday’s (Oct.11th) Exam on the Scientific Method & Metrics System (Units, Tools, Conversions, & Calculations of Volume/Mass/Density) BRING IN A CALCULATOR & PENCIL EVERYDAY!!!

  33. 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)

  34. 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

  35. Mouths Lips Gums K I D S H A V E D I R T Y D R I N K I N G C H O C O L A T E M I L K
