The Metric System

How do we measure things in science?

this lizard is 3 meters long
This lizard is 3 meters long!

(a meter is about 39 inches)

volume measures the amount of space an object takes up
Volume(measures the amount of space an object takes up )
  • Base Unit
    • Liter
      • (liquids)
    • Cubic centimeters
      • (solids)
  • Tool
    • Graduated Cylinder (liquids)
    • Ruler (solids)
graduated cylinders
Graduated Cylinders

Measure the volume of liquids

three steps to reading a graduated cylinder
Three steps to reading a graduated cylinder
  • Place the graduated cylinder on level surface
  • Read at eye level
  • Read from the bottom of the meniscus
measuring volume of a solid
Measuring volume of a solid

This solid is three cubic meters in volume. L x W x H = volume

finding the volume of an irregular object
Finding the volume of an irregular object

1. Place enough water in a graduated cylinder to cover the object. Record the volume.

2. Add the object and record the new volume.

3. Find the difference between the two volumes and that is the volume of the irregular object.

mass measures the amount of matter in an object
Mass (measures the amount of matter in an object)
  • Base Unit
    • gram
  • Tool
    • Electric balance
steps before using a balance
Steps before using a balance
  • Clean the weigh pan
  • Tare the balance (zero it out)
temperature measures heat and chill
Temperature(measures heat and chill)
  • Base Unit
    • Degrees celcius
  • Tool
    • Thermometer

This man is in a freezing cold environment as can be seen by his frozen hair and beard. He is sitting in a natural hot spring that is very warm at the same time!
density
Density
  • How closely the molecules of an object are packed together.
  • Density can be calculated if the mass and volume are known
  • Density = mass divided by volume
slide22
Less dense liquids

float on more dense liquids in this density column

weight of an object
Weight of an object
  • The mass of an object multiplied by the force of gravity.
  • Weight changes if gravity changes. (like on the moon)
  • Mass does not change on the moon.
