Group Work  Part 1: (5-10 minutes)  Work in specialized group on one of the four topics: 1. Metric vs. Customary Systems 2. Metric Units 3. Measuring Matter & Density 4. Precision / Accuracy  Part 2: (5 minutes per topic)  Work in mixed groups to teach each other what you have become experts on in your specialized groups for each of the topics.

Cornell Notes: Please take out your notebook and properly set up your paper. Topic: Chemical & Physical Properties; Density Date: 10/1/2012

Physical and Chemical Properties  Physical properties:  Characteristics that can be measured or observed without changing the object’s composition  Chemical Properties:  Ability of a substance to change into one or more new substances (chemical reaction) Examples: Density, Color, Melting, Boiling, (Phase Changes), Cutting, Folding, Crushing Examples: Chemical Reaction: 1)Gas evolves (comes off) 2)Color change 3)Temperature change

Density  Density is a physical property of matter that is unique for each substance.  For example: The density of gold is g/mL. The density of pure water is 1.00 g/mL.  Density is defined as the amount of mass per unit volume  Density = _mass (g)_ or D = m volume (mL) V  Units = g/mL

Measuring Density (D = m/v)  To find an object’s…  Mass (grams)  Use a balance or scale  Volume (mL)  If the object has a regular shape, you can simply measure the sides and use geometry to calculate volume. If the object has an irregular shape, you can measure volume by the displacement of water in a graduated cylinder. V object = V water with object – V water without object

Practice: Which is more dense? Grape Foam Block

Practice: Calculate the Density of… 1. …an object with a mass of 50g and a volume of 5mL. 2. …an object with a mass of 8g and a volume of 16mL. 3. …an object with a volume of 3mL and a mass of 12g. 4. Which of these objects will float in water? (water’s density = 1.00 g/mL)

Practice: Check your answers Calculate the Density of… 1. …an object with a mass of 50g and a volume of 5mL. D=50g/5mL=10g/mL 2. …an object with a mass of 8g and a volume of 16mL. D=8g/16mL=0.5g/mL 3. …an object with a volume of 3mL and a mass of 12g. D=12g/3mL=4g/mL 4. Which of these objects will float in water? (water’s density = 1.00 g/mL) Object #2 will float, 0.5g/mL < 1g/mL

Cornell Notes: Please take out your notebook and properly set up your paper. Topic: Metric to Metric Conversions Date: 10/8/2012

Metric System  The Metric System…  … started in Europe in the 1800s.  … was adopted by the scientific community as its official measurement system.  … is a system based on 10’s.

Base Units  Base Units = Unit of 1 for different values  Distance or Length = meters (m)  Volume = liters (L)  Mass = grams (g)  Time = seconds (s)  Amount of substance = mole (mol)  Temperature = Kelvin (K) = ° C + 273
