What is SI?

In the late 1700s, The French Academy of Sciences set up a system of weights and measures based on the number ten

Unit A : Chapter 1

What is SI?

This “metric system” was accepted by scientists and governments around the world as the International System of Units, or SI.

SI Units for Length:

Unit A : Chapter 1

what is si26
What is SI?
  • A meter is the SI unit of Length. Other SI units of length are larger or smaller than the meter by factors of 10
  • A centimeter is 1/100th of a meter
  • A kilometer is 1000 meters

Unit A : Chapter 1

SI Units for Volume:

Unit A : Chapter 1

how can matter be measured and compared
How Can Matter Be Measured and Compared?
  • Volume can be measured using a graduated cylinder. It is marked in milliliters (mL).
  • A milliliter is equal to one cubic centimeter (1cc)

SI Units for Mass:

Unit A : Chapter 1

what are three states of matter
What Are Three States of Matter?

Mass is the amount of matter something contains. A large, heavy object has more mass than a small, light object.

Which has more mass?

Unit A : Chapter 1

how can matter be measured and compared31
How Can Matter Be Measured and Compared?

Mass is measured in units called grams and kilograms. When the pans are level, the objects on the two pans have the same mass.

Unit A : Chapter 1

how can matter be measured and compared32
How Can Matter Be Measured and Compared?

Try This!

  • Select 5 objects to measure on a balance.
  • Measure and order the objects from the least to the greatest mass.
  • Share your findings with the class.
  • Can you find objects that have the same mass?

Unit A : Chapter 1

what is si33
What is SI?
  • If you measure the mass and volume of an object, you can calculate its density
  • Density is the amount of matter in a given volume

SI Units for Temperature:

Unit A : Chapter 1

what is si35
What is SI?
  • Temperature is a measure of how hot or cold a substance is
  • Temperature is often measured using the Celsius scale, but the Kelvin scale is also used by scientists
