  1. Matter

  2. Entrance Slip: If I have 346.78 kg of gummy bears, and one gummy bear has a mass of 2.3x10^3 mg. How many gummy bears do I have? Give your answer in two significant figures using scientific notation

  3. Entrance Slip Part 2: If I have 300 mm of string. If I want to evenly divide it between three students. How many m of string would each student receive?

  4. Objectives -I can define and differentiate the key terms associated with matter -I can investigate recent scientific discoveries

  5. Collect Homework and Syllabus

  6. Introduction to Matter -What is matter? -Is anything not considered matter? -What are the three forms of matter?

  7. Modeling the three phases Liquid Gas Solid

  8. You will assigned a phase of matter: As a group you will have to -Model it -Explain the key details associated with that phase of matter You will have 10 minutes, then you will have to present it

  9. Phases of Matter -What differentiates the different forms of matter? -What are the key characteristics? -How can we tell which is which?

  10. Solid, Liquid, Gas -Shape -Compressibility -Volume

  11. Physical Changes: -Reversible -Alter matter but composition stays the same Physical Properties: -Observable qualities

  12. Chemical Property: -What occurs during a chemical reaction -Help ID unknown substances Chemical Change: -Cannot be undone -When reactants go through a reaction it is the end result

  13. Physical or chemical property -Tastes sour -Boiling point -Reacts with water -length -Toxicity

  14. Chemical or Physical Change -Baking a cake -Freezing ice cream -Burning Carbon -Formation of a snowflake -Spoiling milk

  15. Substance: Can’t physically separate Mixture: Combination Of two substances

  16. Is it heterogeneous or homogeneous Oil and vinegar? Chocolate milk?

  17. What is the difference between substance and a heterogeneous mixture?

  18. What is the Law of Conservation of Matter?

  19. What type of matter is this? -Identify the characteristics -Make observations -Develop a claim -Provide evidence to support your claim

  20. Plasma: the fourth form of matter -1879 -https://www.youtube.com/watch?v=AVEGJZxglIg

  21. DARK MATTER

  22. Lab Safety Video: https://www.youtube.com/watch?v=BRDApYgvDqQ

  23. Block Density Experiment: -Determine the order of densities of the blocks -From least dense to the most dense

  24. Objectives Review: -I can define and differentiate the key terms associated with matter -I can investigate recent scientific discoveries
