1. The Metric System

2. What is the Metric System?
The metric system is a system of measurement that is based on the number ten
It is often used in science and in countries around the world

3. How is it different?
The metric system uses meters, grams, liters and Celsius
The English System uses feet, ounces, gallons and Fahrenheit

4. What can be measured?
The metric system can be used to measure mass, volume, length, and temperature

5. What is mass?
Mass is the amount of matter in an object

6. What is volume?
Volume is the amount of space an object occupies

7. What is length?
Length is the distance between two points

8. What is temperature? Temperature is the average motion of particles
We can relate this motion to how hot or cold it is.

9. What is density?
Density is how much mass an object has in a given space.
The formula for density is:
Density = _ Mass__
Volume

10. How do we measure mass? Mass is measured by using a balance
The metric units for mass are the gram (g), and kilogram (kg)

11. What is weight?
Weight is the amount of gravity that acts upon an object

12. Are mass and weight the same?
Mass and weight are different.
Mass is the amount of matter in an object and weight is determined by the amount of gravity and matter in an object.
This is why your weight changes on different planets

13. How do we measure length?
Length is measured using a ruler
The metric units for length are the meter (m), centimeter (cm), and the millimeter (mm)

14. How do we measure volume?
We use a graduated cylinder for liquids
We use a ruler for rectangular solids
(L x W x H)
We use the water displacement method to determine the volume of irregularly shaped objects
The metric units for volume are the liter (L), the cubic centimeter (cm³), and the milliliter (mL)

15. How do we measure temperature?
Temperature is measured using a thermometer
The metric unit for temperature is Celsius (°C)
