The Metric System is a standardized measurement system widely used by scientists for various parameters like length, volume, mass, density, and temperature. Known as the International System of Units (SI), it is based on units of ten, making it easier to use and convert between different measurements. Understanding terms like mass (the amount of matter in an object), volume (the space an object occupies), and density (mass per unit volume) is crucial for practical applications. This guide covers essential tools and techniques for measuring these properties effectively.

Transcription de la présentation

  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

  25. Date: 10/24/2006 Tuesday Aim: How can we determine the density of an object? Do Now: 1. Take out homework. Homework: Density Review Sheet. BRING IN A CALCULATOR & PENCIL EVERYDAY!!!

  26. Date: 10/25/2006 Wednesday Aim: Lab: How can we determine the density of a fluid? Do Now: 1. Take out homework. 2. Read over lab. Homework: Complete Lab & Work on review sheet BRING IN A CALCULATOR & PENCIL EVERYDAY!!!
