  1. Turn in LAST week’s Catalyst Sheet and Pick up papers from the front!Answer the Catalyst below:1. Classify each as a pure substance or a mixture: A. Kool-Aid B. Copper (Cu) C. Sodium Acetate (NaC2H3O2) D. Cookies and Cream Ice Cream2. What is the law of conservation of mass? Magnanimous Monday

  2. BIG GOAL: Class average of 80% Mastery on all Tests and Quizzes!

  3. ExplosionPractice!

  4. Explosion: Rapid fire questions! What day is today? What is the scientific method? What is the first step to the scientific method? What is an experimental problem? What is a hypothesis? What is the Passaic mascot? What is a Pure Substance? What are the 2 types of Pure Substances? Name 3 elements. Name 2 Compounds. What is a Mixture? What are the 2 types of Mixtures? What is a homogeneous Mixture Give 1 example of a Homogeneous Mixture. Give 1 example of a Heterogeneous Mixture. What is the Law of Conservation of Mass? What is 9x8? What is 7x11? What is 6x12? What is 12 x 12? What is the square root of 81? What is the square root of 169? Spell Chemistry.

  5. CHANGE SEATS!

  6. Law of Conservation of Mass

  7. Law of Conservation of Mass states: In a chemical reaction matter can neither be created nor destroyed! In other words…The mass before a chemical reaction equals the mass after the reaction

  8. Again…Mass (g) before a reaction = Mass (g) after the reaction

  9. Demo!

  10. Where did the Matter go?

  11. Video! Magic!

  12. Separation of a Mixture!

  13. Activity: On your table, you have 1 mixture and a few supplies…find a way to separate the mixture! (15 min) Write down your procedure as you go!

  14. Filtration • Filtration is a technique that uses a porous barrier to separate a solid from a liquid. This type of separation involves a mixture poured through a piece of filter paper that has been folded in to a cone shape. The liquid passes through and the solid stays behind.

  15. Distillation Distillation: a method of separating mixtures based on boiling point

  16. Decantation Decantation: a method of separating a solid and a liquid by pouring the liquid off the top of the solid

  17. Chromatography Chromatography is a technique that separates a mixture (called the mobile phase) on the basis of size and the time to travel across the surface of another material (called the stationary phase).

  18. Activity: Now it’s time to try Chromatography! (5 min)

  19. Properties of Matter

  20. Physical Property: A Characteristic that does NOT change the composition of a substance (you can get it back!)

  21. Physical Property Examples: Density Color Boiling Point Melting Point

  22. Chemical Property: A Characteristic that CHANGES the composition of a substance (you can NOT get it back!)

  23. Physical Property Examples: Flammability Toxicity Heat it takes to combust

  24. Physical CHANGE: A Characteristic that does NOT change the composition of a substance (you can get it back!)

  25. Chemical CHANGE: A Characteristic that CHANGES the composition of a substance (you can NOT get it back!)
