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 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
