2 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!!! Date: 9/19/2011 Monday

3 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

4 Does this make sense to you?

5

6 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 mass volume density

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

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

9 1. Length 2. Volume 3. Mass 4. Density 5. Temperature What are…UnitsTools Meter (m) Metric ruler Liter, cm 3 = mL Metric ruler or graduated cylinder Grams (g) Triple-beam balance g/ml or g/cm 3 Tools for mass & volume ºC or K thermometer

21 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) 5cm 2 cm 3cm A.B. 2 cm cube Date: 9/24/2007 Monday

22 24 cm 3 56 cm 3 18 cm 3 36 cm 3 4 cm 3

23 3,600 cm 3 15,000 cm 3 140 cm 3 48,000 cm 3 6,000 cm 3 3,600 cm 3

24 Volume Displacement 1.Add at least 20 mL of water to graduated cylinder. 2.Place the object in the water. 3.Note where the water level rises & then subtract: Final Water Level - Initial Water Level = Volume of the Object

25 50 mL 55 mL 5 mL

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

27 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) Date: 9/25/2007 Tuesday

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

29 499 g 578.6 g 389.3 g

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

31 mass gravity

32 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!!! Date: 9/26/2007 Wednesday

33 722.9 g 200.5 g

34 45.5 g 153.7 g 514.0 g

35 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!!! Date: 9/27/2007 Thursday

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

37 g/mL g/cm 3 D = M/V D = 150g/V (V = 1 x 5 x 2) D = 150g/10cm 3 D = 15g/cm 3

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

39 V = M/D V = 44g / 5.5 g/cm 3 44 g 8 cm 3 V = L x W x H 8 cc = L x W x H 8 cc = 2 x 2 x 2

40 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.11 th ) Exam on the Scientific Method & Metrics System (Units, Tools, Conversions, & Calculations of Volume/Mass/Density) BRING IN A CALCULATOR & PENCIL EVERYDAY!!!
