Group Work

Part 1: (5-10 minutes)

Work in specialized group on one of the four topics:1. Metric vs.

Customary Systems

2. Metric Units3. Measuring Matter

& Density4. 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.

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 change3) Temperature

change

Density

Density is a physical property of matter that is unique for each substance. For example:

The density of gold is 19.32 g/mL. The density of pure water is 1.00 g/mL.

Density is defined as theamount 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.

Vobject = Vwater with object – Vwater 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 answersCalculate 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

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 +
