  1. Warm-Up August 15, 2013 Have name card on desk. Have textbook, binder/notebook, calculator, and signed portion of letter on desk. What is chemistry? How have you encountered/experienced chemistry today? What are the major parts of the scientific method? Write two examples of a qualitative observation, and two examples for a quantitative observation. The two main types of products from the scientific method are _____ and ______.

  2. Warm-Up August 16, 2013 Have name card on desk. Have textbook, binder/notebook, calculator, and signed portion of letter on desk. What is chemistry? How have you encountered/experienced chemistry today? What are the major parts of the scientific method? If a stack of 7 quarters is 1 inch high, how many dollars are in a stack that is 8 feet tall? An average tree makes 2 x 105 toothpicks. Toothpicks are packaged 50 in a box. Each package costs 0.59. How much will it cost in dollars to buy all the toothpicks from 1 average tree? 2 +3(x+5) -7 = 327. What is x?

  3. Agenda August 16, 2013 • Review scientific method and demonstration • Practice identifying different aspects of the scientific method. • Describing Matter: States and Changes • Classifying Matter • Brief History of Chemistry • The Atom • HOMEWORK • Read pgs 4-9 • Section Review pg 9: 2-13 • do NOT need to write questions, only answers. • - Bring a Ziploc bag with cereal. Take a picture of the nutritional facts.

  4. Warm-Up August 19, 2013 Have name card on desk. If you did not have a calculator last week, check in with me at the front. Boron is a good conductor of electricity at high temperatures. What sort of observation is this? Oppositely charged particles attract each other. Is this a law, theory, a hypothesis, an observation? Which state has a definite volume, but no definite shape? Explain why by discussing about atoms and the attractive forces. What are some evidence of a chemical change?

  36. Why Chemistry?

  37. Why Chemistry? Understanding chemistry is ESSENTIAL for understanding much of the natural word, and because chemistry is central to many other disciplines

  38. Why Chemistry? Understanding chemistry is ESSENTIAL for understanding much of the natural word, and because chemistry is central to many other disciplines

  39. What is Chemistry?

  40. What is Chemistry? Chemistry is the study of matter. What is matter?

  41. What is Chemistry? What is matter? Matter is anything that has mass and occupies space. Essentially, matter = stuff.

  42. What is Chemistry? If matter = stuff And chemistry is the study of matter, Then chemistry is the study of…
