EARTH SCIENCE

1
EARTH SCIENCE

• WHAT IS THE GOAL OF SCIENCE?

2

• UNDERSTAND THE WORLD AROUND US...

3
HOW DO WE DO THIS?
4

• GATHER INFORMATION
• GATHER FACTS
• CREATE A SOLID THEORY

5
THEORY
6

• LOGICAL EXPLANATION

7
LAW

• IF A THEORY IS TESTED OVER AND OVER AND DOES NOT
  CHANGE IT IS A LAW

8
AREAS OF SCIENCE

• EARTH
• LIFE
• PHYSICAL

9
GROUPS / BRANCHES OF SCIENCE

• GEOLOGY- EARTHS ORIGINS
• METEOROLOGY-WEATHER CLIMATE ATMPSPHERE
  

• OCEANOLOGY- THE ANIMALS AND THE FEATURES OF
  THE EARTH
• ASTRONOMY- PLANETS - STARS ANY OBJECT IN OUTER
  SPACE

10
ALSO

• ZOOLOGY- ANIMALS
• BOTANY- PLANTS
• ECOLOGY- PLANTS ANIMALS

SCIENTIFIC METHOD
13
SCIENTIFIC METHOD

• RESEARCH
• HYPOTHESIS
• EXPERIMENT
• ANALYSIS
• CONCLUSION

14
STATE THE PROBLEM
15
RESEARCH

• FIND OUT MORE FACTS

16
HYPOYHESIS

• EDUCATED GUESS BASED ON FACTS
• THIS IS NOT.. BUBBA I KNOW THIS..

17
EXPERIMENT

• MUST FIND EVIDENCE TO SUPPORT HYPOTHESIS

18
ANALYSIS

• LOOK AT DATA YOU HAVE GATHERED
• CHARTS
• GRAPHS

19
CONCLUSION

• HOW ARE THE RESULTS SIMILAR OR DIFFERENT FROM
  HYPOTHESIS

20
WHAT DO YOU DO NOW?

• THE ENTIRE THING ALL OVER AGAIN...

21
THE METRICS SYSTEM0RTHE UNIVERSAL LANGAUGE

22
BROUGHT TO YOU BY THE NUMBER

23
METERS

• LENGTH

24
VOLUME

• AMOUNT OF SPACE AN OBJECT TAKES UP
• LIQUID OR SOLID

LITERS
25
MASS

• MATTER IN AN OBJECT

GRAMS
26
WEIGHT

• ATTRACTION DUE TO GRAVITY
• NEWTONS MASS X 9.8

27
DENSITY

• THE RELATIONSHIP BETWEEN MASS AND VOLUME
• HIGH DENSITY LOTS OF STUFF - SINKS
• LOW DENSITY- LITTLE BIT OF STUFF
• FLOATS ON TOP

28
VOLUME

• MASS DIVIDED BY WEIGHT

29
TEMPERATURE

• CELSIUS
• 0 FREEZING
• 100 WATER BOILS

k h da M d c m

• CHANGING UNITS
• MOVE DECIMAL POINT SAME DIRECTION AS YOU MOVE
  ACROSS THE CHART
• km to dm
• you move 4 spaces to right so...
• move decimal point 4 spaces to right
• lets look at an example

34
k h da M d c m

• 6km to ?dm
• you move 4 spaces to right so
• DECIMAL POINT ALWAYS AFTER WHOLE NUMBER
• 6.
• move decimal point 4 spaces to right
• answer...
• 60000

35
k h da M d c m

• 21hm ? dam
• you move 1 space to right so
• DECIMAL POINT AFTER NUMBER
• 21.
• move decimal point 1 space to right
• answer...
• 210

36
k h da M d c m

• 21dam ? mm
• you move 4 spaces to right so
• DECIMAL POINT AFTER NUMBER
• 4.
• move decimal point 4 spaces to right
• answer...
• 40000

37
k h da M d c m

• 28 cm ? dam
• you move 3 spaces to left so
• DECIMAL POINT AFTER NUMBER
• 4.
• move decimal point 3 spaces to left
• answer...
• .004

TELESCOPES
39
REFRACTING TELESCOPE

• USES LENSES TO FOCUS AND DRAW IN LIGHT

40
REFLECTING TELESCOPE

• USES MIRRORS TO FOCUS AND COLLECT LIGHT

41
MULTI MIRROR TELESCOPES

• EX. 6- 72 INCH MIRRORS
• 400- 1 INCH MIRRORS -
  SHAPED LIKE A BEE HIVE
