• ### Matter and Change

1. 1. IS MATTER?Matter is anything that has mass and occupies space.Matter is composed of tiny fundamental particles called atoms.Matter may be invisible, like air.Matter may be heavy , like a rock.
2. 2. IS MATTER?There are 3 Physical States of Matter: 1. Solids 2. Liquids 3. Gases
3. 3. Solids:1. Definite shape2. Definite volume3. Particles cling to one another4. Maintains shape outside of a container5. Amorphous solids: plastics, gels, and glass do not have a any regular internal geometric pattern
4. 4. Liquids:1. NO definite shape2. Definite volume3. Particles stick, but not rigidly4. Does NOT maintain shape outside of a container
5. 5. Gases:1. NO definite shape2. No definite volume3. Particles move independently of one another4. Does NOT maintain shape outside of a container
6. 6. IS MATTER? Matter Pure Substances / Homogeneous Mixture of two of composition more substances Solutions / Heterogeneous Homogeneous Elements Compounds mixtures Two or composition – one more phases phase
7. 7. IS MATTER?Pure Substance:• Single substances• Elements and compounds
8. 8. IS MATTER?Mixture: 2 or more substances:• Mixtures can be separated. They have two types: • Homogeneous – A mixture that is uniform throughout the solution and has the same properties consistently. Example: pool water • Heterogeneous – A mixture where the matter is physically distinct. Example: soil
9. 9. IS MATTER?1. Name 3 different states of matter. 5. Give an example of a pure substance.a.b.c.2. Name 3 characteristics of a solid. 6. Give an example of a compound.a.b.c.3. Name 3 characteristics of a gas. 7. Give one example of a heterogeneous mixture.a.b.c.4. Name 3 characteristics of a liquid. 8. Give one example of a homogeneous mixture.a.b.c.

Lesson Idea for Presentation ExerciseYour Name(s): Tracy ArnoldSubject Area: Secondary Science / ChemistryGrade Level: 9-12Lesson Title/ Matter and ChangeWeb Address http://www.teach-nology.com/lessons/lsn_pln_view_lessons.php?action=view&cat_id=8&lsn_id=1671Curriculum-Nevada State P.12.A.1Standard: Students know different molecular arrangements and motions account for the different physical properties of solids, liquids, and gases.Objectives: Students will know the definition of matter. Students will be able to distinguish between the various physical states of matter and know aspects of each state. Students will be able to differentiate heterogeneous and homogeneous mixtures. Students will know the difference between pure substances and mixtures.Instruction-Procedures: Matter and Change PowerPoint presentation. Copies of slides for student review. Begin with a general overview of matter. Discuss states of matter with graphic. Delineate aspects of each type of matter. Discuss pure substances and mixtures. Discuss heterogeneous and homogeneous mixtures.Assessment- Short group quiz / handout for students to use for exam study. Homework: students are to write a paragraph describingHow will you check student matter. The description shall include a definition of matter, states of matter and one example of EACH state.learning:
