1. anything that takes up space and has mass
What is matter?
anything that takes up space and has mass
matter is made of atoms
mass – the amount of matter in an object
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.

3. What is not matter?
What is matter?

4. 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

6. In science, however, we use 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!

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

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

9. Metric Conversion Stair Step Method
If you move down, the number gets bigger (multiplied). Move the decimal to the right.
kilo- (k) 1,000
hecto- (h) 100
deka- (da) 10
BASE lengthmeter (m) volumeLiter (L) mass gram (g)
deci- (d) .1 or 1/10
If you move up, the number gets smaller (divided). Move the decimal to the left.
centi- (c) or 1/100
milli- (m) or 1/1000

10. mass vs. weight mass 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?
