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)
