What is matter?anything that takes up space and has mass
mass – the amount of matter in an object
matter is made of atoms
If the object has even one atom it
has a very tiny mass. If it has a
lot of atoms, it has
a larger mass.http://education.jlab.org/qa/atom_idx.html

Matter can be measured with different systems
• Many countries had their own systems of measurement
•Eventually almost all countries began using the same system of measurement:
the metric system

Only one country in the world doesn’t use the metric system as it’s national system of measurement:
The United States of America
We use the English System as our national system of measurement
In science, however, we use the metric system!

The metric system was created in France
It is also called
or the International System of Units
Units of the metric system are called SI Units
Systeme International d’Unites

How is matter measured?
mass – the amount of matter in an object
length – the distance from one point to another
English units: inches, feet, yards, miles SI base unit: meter (m)
English units: ounces, pounds, tons SI base unit: gram (g)
English units: teaspoon, cup, pint, quart, gallon
SI base unit: liter (L) *capital
volume – the amount of space an object takes up

If you move down, the number gets bigger (multiplied). Move the
decimal to the right.
If you move up, the number gets smaller (divided). Move the
decimal to the left.

mass vs. weightmass is the amount of matter in an object
weight is a measure of the force of gravity acting on an object
Do you weigh the same on the earth and the moon?
