Anything that has mass and takes up space (volume) is considered matter.
What is Matter?

The amount of matter in a object is its MASS. It is measured with a The base unit is theGRAM.The more matter in the object the more mass it has.

Weight is the pull of gravity on an object’s mass. It is measured with a
Weight depends on the pull of gravity. It can change with location!
What is weight?
scale!

What would you weigh on the moon???
You would weigh 1/6 of what you weigh on Earth!Would your mass change on the moon?
On which planet would you weigh the most?

JUPITER!! WHY???

The amount of space an object takes up is called VOLUME.
Volume can be measured with a
VOLUME
Graduated cylinderThe base unit in the metric system is the LITER but when you use a graduated cylinder what is the unit?milliliters

If the object is a regularly shaped object, measurements can be used to calculate the volume.
Like a box!
Volume can be calculated.

Volume of a box: Volume = L x W x H
What is the volume of this box?
You need to know a formula!
120What are the units? It depends on what the units for each dimension is!!
cm3

The water/liquid in a graduated cylinders makes a curve. It is called a MENISCUS.
Always read the volume from the BOTTOM of the curve! Make sure you are eye level with the meniscus.

What are these volumes?

To find the volume of an irregularly shaped object, you use a method called:
What if the object is irregularly shaped? (like a rock)

What’s the volume of these items?

The base unit for length in the metric system is the METER. It is abbreviated with a m.
Length/distance measurements are made using a RULER or METERSTICK!
Length or Distance

There are 100 centimeters (cm) in 1 meter.
Think about there are 100 cents in a dollar! Smaller divisions are on the meterstick –
MILLIMETERS (mm).

There are 1000 mm in a meter!
