Measurement Must have a standard. A standard is an exact quantity people agree to use for comparison. A standard means two people using the same object should get close to the same results.

Standards of the past People used to use parts of their body to determine the length of something. The standard would be a part of the king’s anatomy. The standard yard was the distance from the king’s nose to his outstretched arm

People would use their feet to measure distance This is how the term foot came about. Today the standard “foot” in the English system is 12 inches = 1 foot

The Standard system is very confusing because it has so many different values

America is the only country that still uses the old English system

Scientists give the English system the thumbs down Scientists needed an exact and uniform system of weights and measurements

How did the metric system come about? During the18th century scientists measured the distance from the earth’s equator to its North Pole and divided it into ten million parts. This is how they came up with the length of the standard meter.

The Meter The standard for the meter is kept in a safe in France. The meter stick is a replica of that standard A meter is made up of 100 centimeters and 1000 millimeters

How the liter came about Scientists needed a way to measure liquids so they took 10 cm and multiplied it by its length x width x height to come up with a standard for measuring volume The liter is the size of 10 cm(3) 10cm x 10 cm x 10 cm Length x Width x Height = Volume The liter is used to measure liquids

How the Gram came about Scientists needed a standard to measure mass. Mass is the amount of matter in an object They decided to take one cubic centimeter of water and call it a gram

The Mistake Two different groups of scientists were working on the calculations to send a probe to Mars. The American team did their calculations in the English standard and the other team did it in the metric system (OOPS!) MARS

This made scientists very upset. It cost the space program 125 million dollars It cost the scientists their time

Metric chart Kilo means thousand (1000) Hecto means hundred (100) Deca means ten (10) Deci means one-tenth (1/10) Centi means one-hundredth (1/100) Milli means one-thousandth (1/1000)

Exit Ticket Using what you learned in this power point and when you completed the prefix models( cereal) ; describe the mathematical pattern within the metric system. ( hint : think of the prefixes)

Copy This Down The Meter- Measures length Length is the distance between two points The Liter –Measures Volume Volume is how much space a liquid takes up The Gram- Measures mass Mass is how much matter is in an object
