Presentation Transcript

  1. Starter: Answer these in your note packet Working with your neighborUsing Dimensional Analysis • Examples: 1. What is the volume of a 250-mL beaker in L? 2. What is your weight in g? 3. How many kg are equivalent to 4 lbs? 4. How many mg are in .500 lbs? 5. How many lbs are equivalent to 4.00 kg?

  2. Starter: Little Extra Practice with Scientific Notation. Convert the following into scientific notation. (On a sheet of notebook paper) • 345.986 • .0000256 • 34.26 x 1034 • 602000000000000 5. 602000000000032

  3. Starter: Little Extra Practice with Sig Figs. Solve for the following. (On a sheet of notebook paper) • .820- .030 = • (240,900)(120.0) = • 340/12.5 =  4. (2.450 x 106)(2.0 x 106) =

  4. Mastery QuizOn Wed/Thur • You have ~40 min • You may take the quiz one or more times during that 40 min. period. • To pass you must get at least a 85% which will earn you full credit (100%) • If you fail to earn an 85% or above during that time, you must retake the test before or after school until it is complete. (No seminar) • You will have until Sep. 19

  5. Mastery QuizOn Wed/Thur • 20 Questions (Randomly selected from a large bank) • Matching • Fill in the blank • Comparison using: <,>, = • Know the S.I. Base units (Example: What is the S.I. base unit for temperature) • Know the S.I. Abbreviations • Have a basic understanding of what the Kelvin and Celsius temperature scales are and how they are used. (Example: Which would be the most appropriate temperature in degrees Celsius for the temperature inside a refrigerator? 100, 30, 20, 5, -80) • Conversions (Example: What is 34.56mm in Km?) • Temperature as well (Example: What is -56.3 C in K)
