1. Topic-
Classification of Matter
2. Content-
Substances vs. Mixtures
Substance Element
Heterogeneous Mixture Solution
Homogeneous Mixture Compound
Tyndall effect Colloid
3. Goals: Aims/Outcomes-
1. Define key terms in unit
2. Identify Substances vs.Mixtures
3. Further identify elements and compounds
4. Compare and contrast: solutions, colloids and suspensions
ESSENTIAL QUESTION.: Can you identify 25 materials in your home as: Substances, mixtures, elements & compounds
4. Objectives-
1. Set up a lab to separate a mixture
2. Work within your group to make a list where your groups agrees as to the type of matter it is
3. Be able to use the vocab. terms correctly in class activities
5. Materials and Aids-
Lab: Sugar, sand, iron filings
Promethean Board
Power point Lesson
6. Procedures/Methods-

A. Introduction-

1. Show a mixture of sand and marbles
2. Ask class to identify what they think this would be called
3. Ask them how we could separate the two materials

B. Development-

Separate the mixture using a screen and a beaker and a tray

C. Practice-

1. Divide the class into 4 groups
2. Give each group a beaker containing a mixture of 3 solids
3. Have each group come up with a method of separating the mixture.
4. Go to lab and apply your plan.

D. Independent Practice-

1. Have student look around their homes and make a list of 20 materials.
2. Classify these materials as substances or mixtures
3. Further classify the substances as elements or compounds

E. Accommodations (Differentiated Instruction)-

Since all groups will be assigned homogeneously there will be no need for differentiation on this lesson

F. Checking for understanding-

1. Next day: students will return with their lists_ Checked off for participation
2. Groups will reform and as a group make a list of 35 objects and their classification.
3. As a group hand in a list--list will be graded 2 points for correct classification and 1 point for miss classification
Group receives a grade for their performance

G. Closure-

1. Go over with class the difficulty of determining classification for materials
2. With a better understanding of what makes up a substance you can better classify it.
7. Evaluation-
1. Students are evaluated on 2 areas:
A. Working as a group to plan a mixture separation and then doing it in the lab
B. As a group agree on the classification of a total of 35 materials and turn in list for evaluation
2pts for correct 1 point for incorrect.
