1. Inspiration for the week.
“The elevator to success is out of order.
You’ll have to use the stairs…one step at a time.”- Joe Girard
Inspiration for the week.
What do you think this means?
_Hard work, perseverance, determination.
Pair Share: I will give you a certain amount of time to talk about only the question asked. Today we will do this throughout the presentation. Sometimes I will look for share outs. Do not get off task. Dojo Points will be rewarded.

2. Physical & Chemical Properties
Materials:
Color Pencils
Pencil
Scissors
Tape or Stapler

3. Review Matter= Anything that has mass and takes up space
Mass= A measure of how much matter is in an object.
Weight= A measure of the force of gravity on an object.
Volume= The amount of space that matter occupies.
Density= The measurement of how much mass of a substance is contained in a given volume

4. Physical Properties Top Left Box
can be observed without changing the identity of the substance.
Examples:
Top Left Box
melting point
boiling point
density
Color
Smell/odor
Elastic
Shape
size
viscosity
conductivity
malleability
hardness
Magnetism
Density
Volume
Thing you can see about the object in front of you.

5. Examples of Physical Properties
Viscosity of a substance is its resistance to flow.
Examples: water = low viscosity
honey = high viscosity
Conductivity is a material’s ability to allow heat to flow.
Examples: metal = high conductivity wood = poor conductivity

6. Examples of Physical Properties
Malleability of a substance is its ability to be hammered into a thin sheet
Melting and Boiling points are the temperatures at which a solid becomes a liquid and a liquid becomes a gas.
Density of a substance is the ratio of its mass compared to its volume.

7. Physical Properties to separate mixtures
Two common separation methods:
Filtration – process that separates materials based on the size of their particles.
Distillation – process that separates the substances in a solution based on their boiling points.

8. Physical Change It is a physical change if . . .
A change in the appearance, without changing the composition of the material.
It is a physical change if . . .
Can be reversible, or irreversible
Substance may seem different, but the way the atoms link up is the same.
It dissolves.
Or the substance changes phase.
It changes shape or size
Choral Response

9. Physical Change Does not form a new substance Bottom Left Box
Draw and label each:
Melting Ice Cream
Streched Rubber Band
Sliced fruit
Bottom Left Box

10. Chemical Properties
Chemical property is any ability to produce a change in the composition of matter.
Examples of chemical properties . . .
flammability
reactivity
Material’s ability to burn in the presence of oxygen.
How readily a substance combines chemically with other substances.

11. Chemical Properties Top Right Box
Describes matter on its ability to change into new matter with different properties. These can only be seen during a chemical change.
Examples:
Rust Flammability
Reactions Explosion
Top Right Box

12. Chemical Changes
occur when a substance reacts and forms one or more new substances with new and different properties.
Bottom Right Box
A change in color.
(Draw a cup with a spot of color)
Production of a gas and bubble are formed.
(Draw test tube with bubbles)
You know a chemical change has occurred when . . .
Solid material forms in a liquid=precipitate
(Draw a cup with a solid square in the middle)
The change is difficult to reverse
(Draw a campfire)
