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

What is matter?

What is not matter?

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?
