Metric Measurement

What is measured with a graduated cylinder?

• Passage of time
• Distance from one thing to another
• Weight of an object
• Volume of liquid

What is special about graduated cylinders?

• They hold large quantities of liquid safely
• They measure small amounts very accurately. We use them when precision is important.
• They allow us to examine the liquid, we use them when looking for suspended solids.
• They are easily heated. We use graduated cylinders to heat liquids

Where is the number 7?

• 7 is not marked. We know that 7 is between 6 and 8, so I infer that it is the longer line between 6 and 8
• We don't know where 7 is. It might be above 8 or below 6
• This cylinder cannot measure 7 because the marking is not there
• 7 is not an important number so it was left off of this piece of lab glassware
