When you take a measurement,
What makes it significant?
The numbers that you measure
Are the ones that you should treasure,
If your measurement is smaller
Than the number ONE,
No need to hollar
Soon you will be done,
Find the first non-zero
Thats on the left side
From that place to the right,
They're all sig figs, what a ride?“
Significant Figure Poem
If your measurement is bigger,
Than the number ONE
Start with the first whole number
to the left,
Your counting’s just begun
Go right to the last number
Don’t include extra zeros
Or look for a decimal point
You’re a sig fig hero!

Significant Figures’ Commandments
1. Thou shall count all non-zero numbers (1,2,3,4,5,6,7,8,9) as significant.
2. Thou shall remember all zeros between non-zero numbers are significant.
3. Thou shalt remember all zeroes which are to the right of the decimal point and at the end of the number are always significant.
4. Thou shall remember all zeroes which are to the left of a written decimal point and are in a number >= 10 are always significant. 2

Meters, liters, and gramsnow you donʼt have to cram
For your examon the metric system
Let me start with ways you can measure a distance, length, or height, Mad tall or super small
one of these will do you right.If you try walkinʼ a meter, itʼs easy to complete
Because a meterʼs just a little bit more than 3 feet.But if youʼre walkinʼ a kilometer itʼs gonna take a while
Itʼs 1000 meters, thatʼs over half a mile!A centimeterʼs dinky
the width of your pinky100 of them go into a meter, you still with me?Thereʼs another kind of meter smaller than that,
Itʼs not very fatitʼs called a millimeter in fact
and itʼs Tiny. 1000 of them in a meter fit,Thatʼs 10 in a centimeter, and thatʼs it!
