Unit 1
Introduction to
What is Earth Science?
• With a partner come up with a definition of
Earth Science:
Earth Science is
• The study of the earth’s land, water and air.
• Earth Science also includes the study of outer
space and the objects in it.
Fields of Earth Science
FIELD
What is Studied
Geology
The Earth’s land, including the surface of
the Earth and the inside of the Earth; how
the Earth changes; history of the Earth
Oceanography
The Earth’s oceans
Meteorology
The Earth’s 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:
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?
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

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
Now let’s learn some density rules
(Now doesn’t 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
Float or Sink
Less dense objects:
Float
More dense objects:
Sink
(http://youtu.be/9K3MM2xuc3U)
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
Activity 1
Does is
Sink or
does it
float?
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
Object
Prediction
Sink or
float
Actual
Sink or
float
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
Now lets come back together and share our findings
So how do we find the density of
an object
