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 reacts 2 – I can explain some parts but need some help 1 – 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 mixture 3 – I can describe what an element, compound and mixture is 2 – I am familiar with elements and compounds 1 – I need to review

Sorting Activity Organize objects into categories of your choice to share with the class 1.Pull items out of envelope 2.Organize on table 3.Grab sticky note & give each category a title/theme 4.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. Substances How 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 Ideas 1.STATES OF MATTER 2.SUBSTANCES Notes 1.SOLIDLIQUIDGAS 1.Substance = 1.Single kind of matter 2.Pure 3.Specific composition 4.Specific properties Ex: salt, copper, water, sugar

Elements

Elements Video Pay attention to: ELEMENT COMPOUND CHEMICAL And 3 specific elements that stand out to you yv6U yv6U

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”

Describing Matter Chpt 2 EQ: How is matter described? Key Ideas 1.STATES OF MATTER 2.SUBSTANCES 1.Element Notes 1.SOLIDLIQUIDGAS 1.Substance = 1.Single kind of matter 2.Pure 3.Specific composition 4.Specific properties Ex: salt, copper, water, sugar 3. Element = a pure substance that cannot be broken down into any other substance Ex: ____, ____, ____

Element Check Are the following elements? – Aluminum (Al) – Copper (Cu) – Oxygen (O 2 ) – Water (H 2 O)

Describing Matter Chpt 2 EQ: How is matter described? 3. Element 4. Compound 3. Element = a pure substance that cannot be broken down into any other substance Ex: Al, H, O 4. Compound = a pure substance made of 2+ elements chemically combined (can’t physically separate) Ex: ______, _______

Describing Matter Chpt 2 EQ: How is matter described? 4. Compound 5. Mixtures 4. Compound = a pure substance made of 2+ elements chemically combined (can’t physically separate) Ex: CO 2 & H 2 O 5. Mixtures = 2+ substances are combined physically 1.Heterogeneous 2.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 = Same GENOUS = kind HETEROGENOUS You can see the different parts of the mixture Substances that are unevenly mixed HETERO = Different GENOUS = kind

Mixtures HOMOGENOUS Milk Salt water Mixture Video HETEROGENOUS Ice & Soda Trail Mix

Mixtures: homogeneous or heterogeneous? Give me an O or E

HOMOGENEOUS

HETEROGENEOUS…

HETEROGENEOUS

HOMOGENEOUS

Describing Matter Chpt 2 EQ: How is matter described? 5. Mixtures5. Mixtures = 2+ substances are combined physically 1.Heterogeneous = unevenly mixed, can pick out pieces Ex: 1.Homogeneous = evenly mixed, can’t see parts Ex:
