Today in class we began with a review on how to add, subtract, multiply and divide with significant digits. Then we got a sheet to work on for practice with working with significant digits. On the back side we worked on formula manipulation and working with word problems.
Ex: light can travel at $3.00 x 10^8 m/s$. How long long will it take for the light to go to the moon?
v = 300 000 000
d = 384 000 000
t = ?
$t = d/v$
$t = 384 000 000/300 000 000$
t = 1.28 sec.
Near the end of class we got our exam review. the person who will be writing Sept. 16 blog will be Michelle.
