Transcript

  • 1. Warm-Up, 08.26.2009 (15 mins)
    Why is the scientific method important? Can you think of anything the scientific method can’t do?
    Why is it important that scientists (and people in everyday life) be as accurate as possible?
    What do you think life was like before systems of measurement were invented?
  • 2. Announcements
    By now you should have turned in:
    Lab Safety Sheet (signed)
    Class Rules/Syllabus (signed)
    By the end of today you should have:
    3 warm-ups & 3 wrap-ups
    Your binder and dividers
  • 3. Today’s Objectives
    Students will be able to:
    Understand how to measure and estimate lengths
    Become more aware of linear measurements in the world and communicate better about the significance of these measurements.
    Understand the importance of measurement in science.
    Understand the relative sizes of things using scientific notation.
  • 4. Measurement
    Baby turtle!!!!!!!!!!!!!omg!!!!!!!!!!

    How do you use the “ladder” method?
    1st – Determine your starting point.
    2nd – Count the “jumps” to your ending point.
    3rd – Move the decimal the same number of jumps in the same direction.

    4 km = _________ m
    How many jumps does it take?
    4.
    = 4000 m
  • 9.
  • 10. Scientific Notation
    A short-hand way of writing
    large numbers without
    writing all of the zeros.
  • 11. The Distance From the Sun to the Earth
    93,000,000
  • 12. Step 1
    Move decimal left
    Leave only one number in front of decimal
    93,000,000 = 9.3000000
  • 13. Step 2
    Write number without zeros
    93,000,000 = 9.3
  • 14. 7
    93,000,000 = 9.3 x 10
    Step 3
    Count how many places you moved decimal
    Make that your power of ten
  • 15. The power of
    ten is 7 because
    the decimal
    moved 7 places.
    7
    93,000,000 = 9.3 x 10
  • 16. 93,000,000 --- Standard Form
    9.3 x 107 --- Scientific Notation
  • 17. Powers of Ten - Video
    I need a two volunteers for after the video
    One will write out the size of the smallest thing we know about.
    One will write out the size of the largest thing we know about.
  • 18.
  • 19. The largest “thing” currently known
  • 20. The smallest measurable “thing” currently known
  • 21. Discovering even smaller particles….
  • 22. Wrap-Up
    If you had one wish, what would it be and why? You can’t wish for more wishes, by the way.
    What did we learn today?
    What is due next class?
  • 23. Metric System Scavenger Hunt
