Transcript of "1/19/12"

  1. 1. 1/19 A/B DayLEQ: How are natural substances differentfrom synthetic ones?1. What is solubility?2. What are three things that can change thesolubility of a substance?3. In salt water, what is the solute and what is thesolvent?4. If a scientist puts a bunch of different objects in anoven, which will get the hottest—the object with thelowest specific heat or the object with the highestspecific heat?5. Explain your answer to #4!
  2. 2. PRACTICE EOG REFLECTION1. Are you satisfied with your score on the practice EOG?2. Why or why not?3. So far this year, are you doing what you need to do in order to reach our class goal of a 3 or 4?4. If you are, what are three things you need to KEEP doing for our next two units? If you are not, what are three things you need to do better on for the rest of the year?5. What surprised you most about the practice EOG?

  18. 18. EOG QUESTION:Which of the following describes the law of conservation of matter?a. matter cannot be created and it cannot bedestroyedb. matter is made of everything and everythingis made of matterc. older layers of rock are at the bottom,younger layers of rock are at the topd. all living things are made of elements andcompounds
  19. 19. Today’s LEQ: How are natural materials different from synthetic ones?By the end of today, you should be able to…1. Describe the difference between natural and synthetic materials2. Identify natural and synthetic materials on the periodic table

  21. 21. CONTEXT CLUES:“This material is synthetic. It’s made in a factory by giant machines.”“This synthetic substance can only be found in specific parts of Charlotte. It is not produced naturally around the world.” Stop and Jot: Write your own definition of
  22. 22. Draw this in your notes:Natural SyntheticChemical Chemical
  23. 23. Synthetic Chemical:• Chemicals that are manmade and do not exist in nature• Examples: steel, bronze, plastic, and all elements with an atomic # of 95 or higher
  24. 24. Natural Chemical:• Chemicals that exist in nature• Examples: water, gold, oxygen
  25. 25. BOTH:• Made of atoms• Forms of matter• Make up all living and non-living things

  28. 28. EOG QUESTION:Which statement applies to all naturalelements? a. they are all found on earth b. they exist in nature c. they are made by humans d. they are all metals
  29. 29. How it’s made: Glass cookware, bars of soap, steel drums, and firefighter jackets
  30. 30. Summarizer: A science teacher tells his students that all natural chemicals are not harmful and all synthetic chemicals are highly dangerous.Based on what you know about natural andsynthetic chemicals, write 3-5 sentences to the science teacher to explain whether you agree or disagree with this statement and WHY.
