1. What are 3 pieces of lab equipment you sorted yesterday and what was their purpose?
2. Were there any pieces of equipment you had never heard of before or never realized it was used for science?
Today’s Standard:2.1 - The student will safely and correctly use equipment, including the following: graduated cylinder, balance, meter stick, thermometer, weather instruments, and glassware.
Silently you are going to walk around the room and visit each station.
At each station you will identify the lab equipment and state what it’s purpose is.

Measurement Notes
Mass: the amount of matter in an object◦ Equipment to measure mass:
Triple Beam Balance Balance Scale
◦ What common units of measure we use to measure this: Grams, Pounds, ounces
Measurement Notes
Weight: the measure of the pull of gravity on an object.◦ Equipment to measure weight:
Scale
◦ What common units of measure we use to measure this: Grams, Pounds, ounces
Measurement Notes
Now mass and weight might seem like the same but they are different. Mass NEVER changes but weight does depending on the amount of gravity.
Measurement Notes
Length: distance between two points◦ Equipment to measure length:
Meter stick
◦ What common units of measure we use to measure this: Meters, Inches, Feet, yards, miles
Measurement Notes
Volume: The amount of space inside a solid◦ Equipment to measure volume:
Meter stick and measure: Length x weight x height Use a graduated cylinder Use a Erlenmeyer flask Use a Beaker
◦ What common units of measure we use to measure this: Liters, Cups

What do you mean there are two measurement systems???
English Units of Measure
AndThe Metric system
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 English 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 downScientists needed an exact and uniform system
of weights and measurements
The “founding father” of the metric system is Gabriel Mouton.
In the 1670’s Gabriel Mouton, the vicar of St. Paul's Church in Lyons, France, proposed a decimal system of measurement.
In 1790, during the French Revolution,the National Assembly of France requested the French Academy of Sciences to
“deduce an invariable standard for all the measures and all the
weights.”
How did the metric system come about?
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.
How did the metric system come about?
The Meter
The standard for the meter is kept in a safe in France.
The meter stick is a replica of that standard.

(CNN) -- NASA lost a $125 million Mars orbiter because one engineering team used metric units while another used English units for a key spacecraft operation, according to a review finding released Thursday.
For that reason, information failed to transfer between the Mars Climate Orbiter spacecraft team at Lockheed Martin in Colorado and the mission navigation team in California. Lockheed Martin built the spacecraft.
The findings of an internal peer review panel at NASA's Jet Propulsion Laboratory showed that the failed information transfer scrambled commands for maneuvering the spacecraft to place it in orbit around Mars. JPL oversaw the Climate Orbiter mission.
"Our inability to recognize and correct this simple error has had major implications," said JPL Director Edward Stone.
The spacecraft completed a nearly 10-month journey to Mars before it was lost on September 23.
The navigation mishap pushed the spacecraft dangerously close to the planet's atmosphere where it presumably burned and broke into pieces, killing the mission on a day when engineers had expected to celebrate the craft's entry into Mars' orbit.
Climate Orbiter was to relay data from an upcoming mission called Mars Polar Lander, set to set down on Mars in December. Now that mission will relay its data via its own radio and another orbiter.
Both Mars Surveyor spacecraft were designed to help scientists understand Mars' water history and the potential for life in the planet's past. There is strong evidence that Mars was once awash with water, but scientists have no clear answers to where the water went and what drove it away.
NASA has convened three panels to look into what led to the loss of the orbiter, including the internal peer review panel that released the Thursday finding.
NASA's metric confusion caused Mars orbiter loss
Why is it so important every country uses the same units of measure?
Answer on your paper
Let’s look at millimeters, how many are there in a centimeter?
Let’s look at a meter stick, can you find the millimeters? Centimeters? Decimeters? Meters?
Let’s look at the relationship between each unit◦ I will do some practice problems on the board to make
sure everyone can convert between all 4
Let’s take a look at a meter stick
Next let’s learn about decameters, hectometers, and kilometers.
Let’s take a look at a meter stick
