Unit 1

• Introduction to

Earth Science
2
What is Earth Science?

• With a partner come up with a definition of
• Earth Science

3
Earth Science is

• The study of the earths land, water and air.
• Earth Science also includes the study of outer
  space and the objects in it.

4
Fields of Earth Science
FIELD What is Studied
Geology The Earths land, including the surface of the Earth and the inside of the Earth how the Earth changes history of the Earth
Oceanography The Earths oceans
Meteorology The Earths Air and weather
Astronomy Outer space, including the planets, stars and other objects in space and how they interact with the Earth

Project 1

• With a partner you are going to work on a Earth
  Science Word Sort
• DIRECTION
• Get materials  
• Fold the paper so that you have three (3)
  sections. Label them
• Astronomy meteorology geology
•  Place the words on the poster board or boards
  that you think is the correct category
• When everyone has finished we will share out and
  then place on walls
• At the end of the year we will revisit these to
  see what we have learned.
• Be creative add pictures and color to your work
• This is your First GRADE

Why is Earth Science important
7
Some Basic Definitions

• Observation
• Using your senses
• What are you 5 senses
• sight
• taste
• touch
• smell
• hearing
• Inferences
• are conclusions based on observations
• Classification
• is grouping on the basis of common properties
• why do we classify?

8
More Definitions

• Mass
• - the amount of matter in an object. It is
  measured in grams
• It is measure with a triple beam balance of a
  electronic balance
• Volume
• - the amount of space that an object
  occupies. It is measured in ml or cm3
• - it is measured with a formula
• length width height
• - Or a graduated cylinder

9
Density

• http//youtu.be/rxb_6UANXqU

10
So what is Density then

• Density is
• the concentration of matter in an
  object
• Huh? What does that mean?
• how much stuff makes up the object
• Which is more dense

11
Now lets learn some density rules

• (Now doesnt that sound like fun)
• As the temperature of a substance increase the
  density will decrease
• example hot air rises
• As the temperature of a substance decrease,
• the density of the object with increase

12
Float or Sink

• Less dense objects
• Float
• More dense objects
• Sink
• (http//youtu.be/9K3MM2xu
  c3U)
• If an object and the fluid are the same density,
  the object will float in the middle of the
  liquid.
• The lower the density of and object the higher it
  will float.
• . And now for the fun stuff

13
Activity 1

• Now we are going to see what happens
• Directions
• 1. find a (1) person to work with.
• 2. get materials from teacher
• 3. Make the following table in your
  notebook
• 4. Fill in the first two columns of your chart
• 5. Now drop the objects in the water one at a
  time and see what happens.
• 6. Record data in the last column.
• 7. Finally , in your notebook place the objects
  in order from least to most dense

• Does is Sink or does it float?

Object Prediction Sink or float Actual Sink or float

So how do we find the density of an object
