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!

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.

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!
