Scientific Notation and Significant Digits - Student Presentation 

Scientists have to work with some very large and some very small numbers. To represent these numbers more easily, they use scientific notation. Scientific notation relies on powers of 10. This video gives examples of how to represent a large and small number and explains powers of ten.

Lyrics:

When you take a measurement
What makes it significant?
The numbers that you measure
Are the ones that you should treasure
When rounding answers off with math
Sig figs can be the easy path
How ever can you see
How many sig figs that there be?
Heres a way for you to tell
Its better than a magic spell
So pay attention to the words
And it wont seem quite as absurd!

If your measurement is smaller 
Than the number ONE
Finding out the sig figs 
Can be a lot of fun
Find the first non-zero 
Thats on the leftward side
From that place on to the right, 
Theyre all sig figs, what a ride!

(0.00350 has three sig figs, starting 
from the 3 and going all the way to the end)

If your measurement is bigger 
Than the number ONE
Start with the first digit
Your countings just begun
Go right to the last integer
Or a line over a zero
Or look for a decimal point
Youre  a sig fig hero!
                                       _  
1300 has two sig figs, 1300 has three
sig figs, 1300. has four sig figs)

In a number that is bigger
Than the number ONE
The zeros on the end 
Could be place-holders, son!
If there is nothing on those zeros
To tell us different
Then the zeros are place holders
(I think thats what I meant!!!)

A line over a zero
Tells us where the sig figs stop
Unless its in the units place
(Then a decimal point youll pop)
And now its time to hear the rule
Please put on your wigs
Bigger than one with a decimal point
Theyre all sig figs!
