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
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
What is matter? Anything that has mass & takes up space Examples: Solid, Liquids, & Gases
Anyone want to work for me this weekend What are units? • Words used to describe numbers • Example: • meters, liters, grams, %, $…
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

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
24 cm3 18 cm3 4 cm3 56 cm3 36 cm3
15,000 cm3 3,600 cm3 140 cm3 6,000 cm3 48,000 cm3 3,600 cm3
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
5 mL 50 mL 55 mL
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
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)

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
g/mL g/cm3 D = M/V D = 150g/V (V = 1 x 5 x 2) D = 150g/10cm3 D = 15g/cm3
D = M/V D = 80g/V V = 65-40 = 25 mL 3.2 g/mL D = 80g/25 mL
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
