BRING IN A CALCULATOR TOMORROW!!!

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

Jeopardy

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

What are units?

• Words used to describe numbers

• Example:

• meters, liters, grams, %, \$…

Meter (m)

Metric ruler
