### Properties of Matter

March 21, 2005

DO NOW
• 1. What tool is used to measure temperature?
• 2. What is one unit used to label temperature?
• 3. What tool is used to view tiny organisms and objects that are too small for the naked eye to see?
GOAL
• To be able to state the characteristics of matter
• To use the proper equipment to measure various characteristics of matter
Length

Definition: The distance between two points

Tool: Ruler, Meterstick

Unit: cm or mm or km

Length
Mass

Definition: The amount of matter in an object

Tool: Triple Beam Balance

Unit: grams

Mass
Volume

Definition: The amount of space an object takes up

Tool: Graduated cylinder (liquids and irregular objects), or ruler (cubes)

Formula for Cubes: V= lxwxh

Units: ml or cm^3

Volume
Density

Definition: The number of particles packed into a space

Sinking or floating in water

Need to measure mass and volume

Formula: D = m/v

Units: g/ml or g/cm^3

Density
Gravity

Definition: Force of attraction between objects (amount of pull on Earth)

Tool: Force Scale

Unit: Newtons

Gravity
Weight

Definition: How much gravity pulls on an object

Tool: Scale

Unit: Newtons or pounds

Depends on

More mass = greater weight

Closer to earth’s core = more gravity pull = more weight

Weight
Inertia

Definition: The resistance of an object to changes in its motion

More mass = more inertia

Inertia
Assessment
• Decide which object has greater inertia. Explain
Assessment
• Explain why this animation is an example of inertia
Assessment
• Evaluate this statement: The people in the diagram have the same mass, but different weights. How is this possible?
Assessment
• A cube has a length of 2cm, a width of 3 cm and a height of 4 cm. It also has a mass of 48 g. What is it’s density? Will it sink or float when placed in water?
Assessment
• A liquid has a mass of 12 g and a volume of 36ml. What is it’s density? What will happen if it’s poured into a cup of water?
Assessment
• Which of the two cubes has a greater density? Explain
Assessment
• What is the volume of liquid in each graduated cylinder?
Assessment
• What is the volume of this cube?

1 cm

7 cm

3 cm

Assessment
• What is the mass of this object?
Assessment
• What is the mass of this object?
Assessment
• What is the mass of this object?
Assessment
• Work with your partner on the “Measurement Practice” sheet
• You will be performing a variety of measurements on several objects
• We will go over the answers when you have completed it
