NOTEBOOK SETUP

OBJECTIVES

SWBAT classify a mixture as a suspension, colloidor solution.

SWBAT identify the properties of homogeneousand heterogeneous mixtures.

CLASSIFYING MATTER CONCEPT MAP

Today we will create concept maps. A concept map helps us organize our information we review in class.

MATTER

Objects that take up space and have mass.

Everything in the universe is made up of MATTER.

Matter cannot not be created or destroyed by any chemical or physical process

PURE SUBSTANCES

Compounds

Chemical combinations of two or more atoms ex: NaCl, MgCl2, HCl

Elements

Made up of atoms, cannot be further separated by physical or chemical means ex: sodium, potassium

Substances that are made of only one type of atom or molecule.

MIXTURES

Heterogeneous

Mixture where the substances are not evenly distributed.

They usually involve a mixture of a solid in a solid.

Homogeneous

Mixture where the materials are evenly distributed.

Usually involves a mixture of two or more liquids, gases or a solid that dissolves in a liquid

Salad Soup Taco

Kool-Aid Iron Shavings

A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs

SUSPENSION

This type of mixture will create different layers for each substance in the mixture.

Example:

A suspension is a heterogeneous mixture containing solid particles that are sufficiently large for sedimentation. Usually they must be larger than one micrometer.

Seperatory FunnelOrganic Chemistry

COLLOIDS

Has the ability to scatter light.

Colloids include gels, sols, and emulsions; the particles do not settle and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.

Example:

A type of heterogeneous mixture that consists of particles of one substance dispersed through a second substance.

Mayonnaise Fog Smog

SOLUTION

Particles, atoms, ions, or compounds that WILL NOT scatter light.

Solution have 2 parts a solvent and a solute.

Examples:

Water Clean Air Salt Water

A type of homogeneous mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).

CONCEPT MAP ACTIVITY

Chemists study many thousands of natural substances from the earth's crust, the atmosphere, and the oceans, as well as synthetic substances produced in their laboratories. In order to simplify the task of learning about all of these different materials, scientists have developed classification schemes. How can different kinds of matter be classified to help scientists learn

about their properties?

What are the relationships between the categories and types of matter in the world?

How are compounds, elements, mixtures, and pure substances related to each other?
