• Meters (m)
• Milliliters (mL)
• Grams (g)
• Degrees Celsius (?)
• Grams/millilter (g/mL)
• Grams/centimeter cubed (g/cm³)

• Length
• Volume
• Mass
• Temperature
• Density

Length

• What unit of length Kilometers, Meters,
  Centimeters, Millimeters, micrometers would you
  use to measure the length of

• Kilometers
• Micrometers
• Meters
• Centimeters
• millimeters

• State of NY
• A bacteria cell
• This room
• Your hand
• A diamond

4
Volume

• Liquid Volume is measured by a graduated cylinder
  in milliliters (mL). You read the volume by
  measuring the meniscus, the bottom of the loop.
• The volume of solid, regular shape objects is
  found by using a ruler (L x W x H ) and is
  measured in centimeters cubed (cm³)

Mass

• Mass is NOT Weight!
• Mass on moon is the same as on Earth
• Weight on moon is much smaller than on earth.
• Why... Because mass is the amount of matter
  inside of something, weight is a measure of the
  attraction between two objects due to gravity.

Question

• A ship has a mass of 500 kg, a huge boulder has
  the same mass of 500kg. What happens when you
  put both the ship and the boulder in the ocean?
• The ship FLOATS and the boulder SINKS!
• Why???

8
Density

• Density is the amount of mass in a given volume
• The mass of the ship and the boulder are the same
• BUT the Volume of the ship is much LARGER than
  the volume of the boulder

Temperature

• The metric system uses Degrees Celsius
• Water boils at 100C
• Ice melts at 0C
• The body temperature of humans is 37C
