SUCCESS

• Please work quietly during SUCCESS

• I have several students taking a quiz so there should not be any talking.

11/4/14

WARM UP:Pull out notes book and set up your notes as,“Describing Matter”.

Then write the date.

The EQ is “How is matter described?”

ANNOUNCEMENTS:• WEDS: – Finish Grading Water Lab

• FRI: Read & annotate Chpt 2– Elements– Compounds– Mixtures– ARTICLE DUE (on

website)

Learning Goal: Matter

4 - I can teach how matter is described based on properties and its composition. I can apply how it reacts with other substances.3 – I can explain some properties of matter and how it reacts2 – I can explain some parts but need some help1 – I can answer some questions and need more help

Learning Goal: Properties of Matter

4 – I can analyze substances based on properties to determine if they’re an element, compound, or type of mixture3 – I can describe what an element, compound and mixture is2 – I am familiar with elements and compounds1 – I need to review

Sorting Activity• Organize objects into categories of your choice

to share with the class1. Pull items out of envelope2. Organize on table3. Grab sticky note & give each category a

title/theme4. Walk-about classroom

1. Observe categories – note any differences from yours

2. Rotate clockwise as a table

Classifying Matter

EQ: How is matter classified?

What are some ways you’d categorize it?

1. States of Matter

• Slower moving particles =

• Sliding back and forth particles =

• Rapidly moving particles =

2. SubstancesHow would you describe/categorize the following?

Write on your whiteboards the titles for your categories:

• Salt• Sugar• Baking soda

• Flour• Milk• Eggs• Cookies

2. Substances

SUBSTANCE

• Salt• Sugar• Baking soda

MIXTURE

• Flour• Milk• Eggs• Cookies

Describing Matter Chpt 2

EQ: How is matter described?• Key Ideas1. STATES OF

MATTER

2. SUBSTANCES

• Notes1. SOLID LIQUID GAS

2. Substance = 1. Single kind of matter2. Pure3. Specific composition4. Specific propertiesEx: salt, copper, water, sugar

Elements

Elements Video

Pay attention to:• ELEMENT• COMPOUND• CHEMICAL• And 3 specific elements that stand out to you• https://www.youtube.com/watch?v=Uy0m7jn

Element

• What are some elements that stood out to you?

• What did they mean when they said “compound”?

• So is an element a “substance” or “mixture”

2. SUBSTANCES

3. Element

• Notes1. SOLID LIQUID GAS

2. Substance = 1. Single kind of matter2. Pure3. Specific composition4. Specific propertiesEx: salt, copper, water, sugar

3. Element = a pure substance that cannot be broken down into any other substanceEx: ____, ____, ____

Element Check

• Are the following elements?– Aluminum (Al)– Copper (Cu)– Oxygen (O2)

– Water (H2O)

Describing Matter Chpt 2EQ: How is matter described?3. Element

4. Compound

3. Element = a pure substance that cannot be broken down into any other substanceEx: Al, H, O

4. Compound = a pure substance made of 2+ elements chemically combined (can’t physically separate)

Ex: ______, _______

Describing Matter Chpt 2EQ: How is matter described?4. Compound

5. Mixtures

4. Compound = a pure substance made of 2+ elements chemically combined (can’t physically separate)

Ex: CO2 & H2O

5. Mixtures = 2+ substances are combined physically1. Heterogeneous2. Homogeneous

Mixtures – heterogeneous or homogeneous?

HOMOGENOUS• You cannot see the different

parts of the mixture• Substances are evenly

mixed

HETEROGENOUS• You can see the different

parts of the mixture• Substances that are

unevenly mixed

Mixtures

HOMOGENOUS• You cannot see the different

parts of the mixture• Substances are evenly

mixed

HOMO = SameGENOUS = kind

HETEROGENOUS• You can see the different

parts of the mixture• Substances that are

unevenly mixed

HETERO = DifferentGENOUS = kind

Mixtures

HOMOGENOUS

Milk

Salt water
