What is the metric system?
• A standard system used by scientists to measure
Length,Volume,Mass,Density, &Temperature
• Based on units of 10• A.K.A. International System of
Units or SI
Does this make sense to you?
What is ______?
What is ______?
What is ______?
The amount of matter in an object
The amount of space an object takes up
The amount of matter in a given volume of an object
mass
volume
density
What is matter? • Anything that has mass & takes up space
• Examples:Solid, Liquids, & Gases
Anyone want to work for me this weekend
