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 ScienceFIELD 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 SinkLess 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 1Now 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 denseNow lets come back together and share our findings
Does is Sink or does it float?
Object Prediction Sink or float
ActualSink or float
So how do we find the density of an object
