ESSENTIAL QUESTION 1. What are mixtures (solutions, colloids and suspensions? 2. How do we differentiate between elements, compounds & mixtures?

WHY IS THIS IMPORTANT ? TODAY I WILL ……. learn how to differentiate between SOLUTIONS, COLLOIDS & SUSPENSIONS. THIS IS IMPORTANT BECAUSE. . . because they are all MIXTURES.

ACTIVATOR DIRECTIONS : 1) LISTEN TO THE “SMASH-SONG/ VIDEO” from Glee Club 1) IDENTIFY THE MIXTURE OF SONGS

MIXTURES The Learning Period

• Elements • All elements are made of atoms. • Atoms of the same element are alike. • Atoms of different elements are different.

• Compounds are also pure substances. • But compounds are made from more than one element. • Water is a compound. • Water can be broken down into simpler substances – hydrogen and oxygen. •

• A mixture is a combination of two or more substances where there is no chemical combination or reaction. www. brainybetty. com 11

• Mixtures combine physically in no specific proportions. They just mix. www. brainybetty. com 12

Mixtures are classified as: HOMOGENOUS/HETEROGENO US SOLUTIONS COLLOIDS SUSPENSIONS www. brainybetty. com 13

COLLOIDS

• Colloids In a colloid the particles are mixed together but not dissolved. • The particles are relatively large and are kept permanently suspended. •

• Colloids A colloid will not separate upon standing. • The particles are constantly colliding, and this allows a colloid to scatter light – thus colloids often seem cloudy. •

Heterogeneous Mixtures (cont. ) Colloids are heterogeneous mixtures of intermediate sized particles (between 1 nm and 1000 nm) and do not settle out. Colloids are categorized according to the phases of their particles.

Heterogeneous Mixtures (cont. ) • Section 14 -1

SOLUTIONS

• Solutions A solution is a type of homogeneous mixture formed when one substance dissolves in another. • It is the best mixed of all mixtures. • A solution always has a substance that is dissolved and a substance that does the dissolving. • The substance that is dissolved is the solute and the substance that does the dissolving is the solvent. •

• Ocean water is a solution

• The universal solvent: Water

• Water as a solvent • Many liquid solutions contain water as the solvent. • Ocean water is basically a water solution that contains many salts. • Body fluids are also water solutions.

• Types of solutions Solute Solvent Example Gas Gas Liquid Solid Liquid Air (oxygen in nitrogen) Soda water (carbon dioxide in water) Ocean water (salt in water) Solid Gold jewelry (copper in gold)

• Air is a solution of oxygen and other gases dissolved in nitrogen

Homogeneous Mixtures (cont. ) • Section 14 -1

SUSPENSIONS

Suspension - a heterogeneous mixture in which the particles are large enough to be seen by a microscope or the unaided eye (eventually, they settle out of the mixture). Example: stirring a teaspoon of dirt in a glass of water.

CLASSWORK Directions: create a Triple Venn Diagram, or 3 Column Tchart to learn about the new vocabulary words. Each circle/chart needs to have 3 keys points, and 2 examples. • Solutions • Colloids • Suspension • Mixtures • Elements • Compounds

WE ARE TESTING !!!!!

SOCRATIC SEMINAR Directions: WE will participate in a Socratic seminar over the article. This is a dialogue discussion. Students will get a ticket. Their ticket is their way into the conversation. Students must keep the conversation advanced.

Closing Today I felt about the quiz…… Use the subatomic particle faces to describe what you feel your performance on the quiz was:

ESSENTIAL QUESTION 1. How do we differentiate between homogenous, elements, compounds & mixtures?

WHY IS THIS IMPORTANT ? TODAY I WILL ……. learn how to differentiate between heterogeneous & homogenous MIXTURES. THIS IS IMPORTANT BECAUSE. . . because MIXTURES are uniform and can be visually seen.

ACTIVATOR MAKE A PREDICTION…. . WHAT DO YOU THINK THE DIFFERENCES BETWEEN HOMOGENOUS & HETEROGENOUS MIXTURES ARE ?

• Is it uniform throughout? • If the answer is no, the matter is a heterogeneous mixture. Considered the “least mixed. ” • Does not appear to be the same throughout. • Particles are large enough to be seen and to be separated from the mixture. •

• Examples of heterogeneous mixtures • Sand pebbles • Oil and water • Powdered iron and powdered sulfur

• Examples of heterogeneous mixtures • Sand pebbles • Oil and water • Powdered iron and powdered sulfur

• Is it uniform throughout? • If the answer is yes, the matter is homogeneous (looks the same throughout). • That leads us to another question.

• Homogeneous Mixtures • A mixture that appears to be the same throughout. • It is “well mixed. ” • The particles that make up the mixture are very small and not easily recognizable.

• Examples of homogeneous mixtures Milk, toothpaste, and mayonnaise are homogeneous mixtures. They are also colloids.

Closing Illustrate !!!! Create a picture of your own examples of heterogeneous and homogeneous mixtures.

ESSENTIAL QUESTION 1. What is the difference between physical & chemical changes ?

WHY IS THIS IMPORTANT ? TODAY I WILL ……. learn how to differentiate between physical & chemical changes. THIS IS IMPORTANT BECAUSE. . . because it is important to understand how matter changes.

ACTIVATOR WHAT HAPPENED TO THE MILK ?

Mixtures, elements, compounds • Scientists like to classify things. • One way that scientists classify matter is by its composition. • Ultimately, all matter can be classified as mixtures, elements and compounds.

By asking these questions scientists can classify matter into: • Mixtures – two or more substances that are not chemically combined with each other and can be separated by physical means. The substances in a mixture retain their individual properties. • Solutions – a special kind of mixture where one substance dissolves in another. Elements – simplest form of pure substance. They cannot be broken into anything else by physical or chemical means. • Compounds – pure substances that are the unions of two or more elements. They can be broken into simpler substances by chemical means. •

• Elements • All elements are made of atoms. • Atoms of the same element are alike. • Atoms of different elements are different.

• Elements • In 1813, a system of representing elements with symbols was introduced. • • Each symbol consists of one or two letters. Two letters are needed for a chemical symbol when the first letter of that element’s name has already been used.

• Compounds are also pure substances. • But compounds are made from more than one element. • Water is a compound. • Water can be broken down into simpler substances – hydrogen and oxygen. •
