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! six sig figs 1

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

The Domestic Animal Chase Good Moral kittens hate dogs* But do chase many mice** normally * deka prefix = “ da ” not “d” ** micro prefix = “ μ ” not “m” 4

The Nonchalant Killer Millipedes Gigantic Millipedes killed hundreds down* By david’s charming magnificent mansion** nonchalantly * deka prefix = “ da ” not “d” ** micro prefix = “ μ ” not “m” 3

Knock Knock! George Mason knocked his door* But didn’t call mrs. mason’s** name * deka prefix = “ da ” not “d” ** micro prefix = “ μ ” not “m” 5

Meters, liters, and grams now you don ʼ t have to cram For your exam on 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 walkin ʼ a meter, it ʼ s easy to complete Because a meter ʼ s just a little bit more than 3 feet. But if you ʼ re walkin ʼ a kilometer it ʼ s gonna take a while It ʼ s 1000 meters, that ʼ s over half a mile! A centimeter ʼ s dinky the width of your pinky 100 of them go into a meter, you still with me? There ʼ s another kind of meter smaller than that, It ʼ s not very fat it ʼ s called a millimeter in fact and it ʼ s Tiny. 1000 of them in a meter fit, That ʼ s 10 in a centimeter, and that ʼ s it! Metric System Poem 6
