What is Earth Science??
1. List and describe the 4 main branches of Earth Science.
2. List and describe the 4 spheres of the Earth.
3. What do we mean by the Earth works as a “system”?
What is Earth Science??
1. List and describe the 4 main branches of Earth Science.– Geology, meteorology, astronomy, oceanography
2. List and describe the 4 spheres of the Earth.– Lithosphere, atmosphere, hydrosphere, biosphere
3. What do we mean by the Earth works as a “system”?
Earth works as a “System” – If you change something in one sphere another sphere will be affected
Scientific Inquiry
4. What is the scientific method?
5. What are the 6 steps of the scientific method?
6. What is a “hypothesis” and what must be?
7. What is the difference between an observation and an inference?
Scientific Inquiry4. What is the scientific method?
Series of steps scientists use to solve a problem5. What are the 6 steps of the scientific method?
1. Ask a question/state the problem2. Research / Observation3. Hypothesis4. Experiment5. Analyze Results6. Conclusion
6. What is a “hypothesis” and what must be?an educated guess and TESTABLE
7. What is the difference between an observation and an inference? An observation is based on your senses (ex. Sight, smell , touch, etc…) Inference is an EXPLANATION of the observation.
Experimental Design
6 When you design an experiment how many variables do you change?
7 What is the independent variable in an experiment?
8 What is the dependent variable in an experiment?
Experimental Design
6 When you design an experiment how many variables do you change?

Experimental Design Problem
12. Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. One tree is left outside in normal conditions. Height of the tree is measured once a week.
• List the following:– Independent variable– Dependent variable– Controlled variables– Control Group– Experimental Group
Experimental Design Problem
12. Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. One tree is left outside in normal conditions. Height of the tree is measured once a week.
• List the following:– Independent variable
• Humidity levels
– Dependent variable• Height of tree
– Controlled variables• Type of tree, same time
– Control Group• Tree outside
– Experimental Group• Trees in greenhouse
Measurement
13.The information gathered during an experiment is called ________.
14.What is the difference between qualitative data and quantitative data?
Measurement
13.The information gathered during an experiment is called data.
14.What is the difference between qualitative data and quantitative data?
Qualitative = data from senses (bubbly, rough, etc..)Quantitative = data based on numbers (12 mL, etc..)
Measurement
15.List the units and tool used to measure for the following;– Mass– Volume (solid)– Volume (liquid)– Temperature– Length– Weight
Measurement
15.List the units for the following;– Mass – grams (g) – BALANCE– Volume (solid) – centimeter cubed (cm3) - RULER– Volume (liquid) – liters (l) – GRADUATED CYLINDER– Temperature – Celsius (C ) - THERMOMETER– Length – meters (m) – METER STICK– Weight – Newtons ( N) – SPRING SCALE
