CW2: Scientific Notation Practice & Intro. to Measurement
Chemistry
Due Date: August 27, 2013
SWBAT convert between standard & scientific notation.
SWBAT list and describe the appropriate equipment to take scientific measurements of
mass, length, volume, and temperature.
DO NOW:
1.
How should you if you need extra
help in chemistry?
4.
7.
2.
What does the classroom rule
“Respect Your Own Ideas mean to
you?
What are some common units for
mass?
What should you do the beginning of
every class period?
5.
8.
3.
How do you write 35,700 in
scientific notation?
What is something you’re really good
at?
How do you get your name onto the
“FAB FIVE” wall?
6.
9.
How do you write 4.8 x 103 in
standard notation?
What is one of your biggest regrets?
WHY?
1. Circle the number that is easier and faster to write:
A: 602, 200, 000, 000, 000, 000, 000, 000 = _____________________________ notation
B: 6.022 x 1023 = __________________________________ notation
Guess what? 602, 200, 000, 000, 000, 000, 000, 000 _____ 6.022 x 1023
2. Circle the number that is easier and faster to write:
A: 0.00000000000000000000000043 = _____________________________ notation
B: 4.3 x 10-25 = _____________________________ notation
Guess what? 0.00000000000000000000000043 _________ 4.3 x 10-25
Scientific notation is an ________________ way to write very ___________________ or very
__________________ numbers in science.
