1 Introduction to Global Science Ch. 1

2 Four Branches of Earth Science Match the Branch with the Picture!!! 1.Geology 2.Oceanography 3.Meteorology 4.Astronomy A B C D

3 Importance of Earth Science Journal: Why might studying Earth Science be valuable?

4 Ecology Where earth science and biology meet!!! Earth scientists study the solid earth, water, and the atmosphere. –These nonliving parts of earth are related to the living parts of earth. –Example: Ecosystem

5 How is Earth Science Studied? The Scientific Method –Observation –Research the topic –Form a Hypothesis –Test the Hypothesis (Experiment) –Conclusion

6

7 Hypothesis An explanation for a question or a problem that can be tested. It is NOT a random guess!!! Question: How does sunlight affect plant growth? Example Hypothesis: An increase in sunlight will improve plant growth. –Can be phrased as an “If, then statement” –Example: If the amount of sun exposure is increased, then plants will have an increase in growth as measured by height.

8 Think / Pair / Share Journal Create your own testable hypothesis. It can be about anything school appropriate.

9 Experiment Collecting information under controlled conditions Control Group: part of an experiment that is a standard against which results are compared. –Receives no experimental treatment. Experimental Group: one condition is changed in order to observe the result ControlExperimental (Test) Group No FertilizerFertilizer

10 Collect Data Quantitative Data: numerical –Measurements of time, temperature, height, mass, area, etc. Qualitative Data: descriptions

11 Conclusion Was the hypothesis supported by the results of the experiment? Is more data needed? –Experiment need to be repeated several times with similar results –Experiments need to be reviewed by other scientists

12 Review Journal List the steps of the scientific method Journal Explain the difference between a control and experimental group
