1. STAAR Chemistry Review Topic: Matter and its properties TEKS – The student knows the characteristics of matter and can analyze the relationships between chemical and physical changes and properties.

2. Student Expectation (4A) --differentiate between physical and chemical changes and properties.

3. Index Card Time Title: Changes Front: Physical Changes Back: Change in size, shape or state. Examples:

4. Physical Properties Malleable : Ability to be hammered into thin sheets Ductile: Ability to be drawn into a wire Luster: Ability to reflect the light

5. Index Card Time Title: Matter Changes Front: Chemical Changes Back: New substance forms. Color change. Temperature change (endo/exo). Gas forms. Precipitate (solid) forms.

6. 5 Signs of a Chemical Reaction There are five indicators that a chemical reaction has taken place. They are… 1.Color change 2.Temp. change 3.Gas. 4.Appearance of a precipitate (solid) 5.Light.

7. Physical or Chemical properties? 1.rusting iron Answer: Chemical 2. dissolving in water Answer: Physical 3. burning a log Answer: Chemical 4. melting ice Answer: Physical 5. grinding spices Answer: Physical

8. Physical or Chemical Changes Precipitant All phases changes are physical

9. Student Expectation (4C) Compare solids, liquids, and gases in terms of compressibility, structure, shape and volume.

10. Index Card Time Title: States of Matter and Properties Back: Make a chart which includes solid, liquid and gas and the properties of shape, volume, compressibility and a diagram. ShapeVolumeCompressibility (high or low) Sketch a diagram Solid Liquid Gas

11. Compressibility and the spacing of particles. Particle vibrate in fixed position Constant random motion spaced far apart. Particles slide past one another

12. What happens to the gas particles in a balloon when it is compressed?

13. Student Expectation (4B) --- identify extensive and intensive properties.

14. Index Card Time Title: Intensive vs. Extensive Properties Front: INTENSIVE IS SO INTENSE THAT THE AMOUNT OF MATTER DOESN’T MATTER!!!!! Back: Examples of each

15. Intensive or Extensive? 1.Boiling point Answer: Intensive 2. Melting point Answer: Intensive 3. Color Answer: Intensive 4. Odor Answer: Intensive 5. Mass Answer: Extensive

16. Student Expectation (4D) Classify matter as pure substances or mixtures through investigation of their properties.

17. Index Card Time Title: Substances and Mixtures Back: Make the flow chart for classifying matter. Include examples for each category.

18. Flow chart

19. Element Pure and made up of only itself!!!! Pure

20. Compounds: Combining two or more elements together. Chemically combined. The same no matter where you find the compound. Pure!!!!

21. Mixtures Can be separated physically, not chemically combined. Homogeneous or Heterogeneous Made of several different types of atoms and element. Solution Homogeneous Salt Water solution Homogeneous Heterogeneous Mixture

22. Learning Check Identify if the following are 1) Homogeneous or 2) Heterogenous 1.__air 4. __ salad dressing 2.__ink5. __coffee (black) 3.__ soft drink 6. __Chicken noodle soup

23. Learning Check Identify if the following are 1) Homogeneous or 2) Heterogenous 1. 1 air 4. 2 salad dressing 2. 1 ink5. 1 coffee 3. 1soft drink6. 2 Chicken noodle soup
