The Metric System

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

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

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

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

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

What is length?  Length is the distance between two points

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

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

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

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

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

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)

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)

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