Metric Mania FND CHEMISTRY MS.PSTRZOCH
Once Upon a Time… in a faraway land named Metric Kingdom, there lived a king who loved chocolate milk. His name was King Henry.
Throughout his kingdom, King Henry made sure that all of the cows were fed great supplies of chocolate to continue to provide him with his beloved chocolate milk drink.
King Henry drank chocolate milk with his breakfast. He drank chocolate milk with his lunch. He drank chocolate milk with his dinner. He even drank chocolate milk for his bedtime snack. King Henry drank chocolate milk by the liters!
King Henry was so obsessed with his chocolate milk that he wrote a decree making it illegal for anyone to drink chocolate milk, except for himself.
After visiting the King, the doctor revealed something miraculous: the King was the healthiest he’d ever been! King Henry’s wife was concerned about the amount of chocolate milk he was drinking. She called the doctor to check him out.
The chocolate milk had made the King stronger taller faster and handsomer!
After hearing the news, the King drank more chocolate milk than ever. He drank, and drank, and drank his chocolate milk, until one day King Henry unexpectedly died! His body just couldn’t process all of the chocolate! Sadly, King Henry Died By Drinking Chocolate Milk
The Gift King Henry Left for his People of Metric Kingdom: King Henry may have died a long time ago, but his Metric Kingdom remembers him every year when students learn metric conversions. His RIP statement helps us remember the prefixes for metric measurement and how to order the units from greatest to smallest.

Metric System • Metric system is based on the power of 10. • Meter is a measure of length. • Gram is a measure of mass. • Liter is a measure of liquid volume.
Converting Units • To convert from one unit to another is like walking up and down steps. • Going Up • When going from a smaller unit to a larger unit, you move UP the steps and the decimal moves to the LEFT. • Going Down • When going from a larger unit to a smaller unit, you move DOWN the steps and the decimal moves to the RIGHT.

Decimal place moves to the RIGHT the same number of steps. • Find the measurement your starting with on the ladder. • Find the measurement you are converting to on the ladder. • Identify if you are moving up or down the ladder. • Then identify if you are moving your decimal to the right or left.
