The Metric System

• SI (System International)

8
Metric System

• Used by every country in the world, except the
  USA.
• Always used by scientists.
• Based on the number 10, so its easy!

9
Measuring Length

• Length the distance between 2 points.
• Base unit meter (m)
• Use rulers and meter sticks to measure

10

• Problems
• We need more accuracy
• We cant measure everything with just base units
• We need prefixes!

Measuring Volume
We will be using graduated cylinders to find the
volume of liquids and other objects.
Read the measurement based on the bottom of the
meniscus or curve. When using a real cylinder,
make sure you are eye-level with the level of the
water. What is the volume of water in the
cylinder? _____mL
