What are the four branches of Earth Science? |
Oceanography, Meteorology, Astronomy, Geology |
|
|
Geology: What is it, what is an event, what is an activity |
It's the study of the origin, history, and structure of Earth. Event: earthquakes, volcanoes Activity: map earthquakes |
|
|
Meteorology: What is it, what is an event, what is an activity |
It's the study of the atmosphere and weather processes. (climate) Event: thunderstorms, tornado Activity: study/ predict weather |
|
|
Astronomy: What is it, what is an event, what is an activity |
It's the study of stars, other planets, and other objects in space. Event: solar eclipse Activity: study comets |
|
|
Oceanography: What is it, what is an event, what is an activity |
It's the study of the sea. Event: coastal erosion Activity: track ocean currents, study ocean floors |
|
|
Fact and Opinion |
A fact is something that can be proven. An opinion can't be proven. Opinions are based on thoughts, feelings, and someone's understanding. |
|
|
Theories and Laws |
A theory is an explanation of observations or events. A theory tells why something is going to happen. A law is a rule that describes a pattern in nature. A law just states that something will happen. |
|
|
Three main branches of science |
Earth Science, Physical Science, Life Science |
|
|
Steps of Scientific Method |
1. Observe/Ask questions 2. Form a hypothesis 3.Test the hypothesis (Experiment) 4. Analyzing data and draw conclusions 5. Share your results |
|
|
Variables and Groups |
A variable is a changeable factor in an experiment. Control Group- The group that is standard for comparison. it's the original. Experimental group- The group with the changeable factor. |
|
|
Bunsen Burner safety procedures |
Glasses or goggles need to be worn. Hair must be tied back and loose clothing must be tucked in. If not lit at first, turn off the gas. Use proper tools when handling hot objects. |
|
|
Safe lab practices |
You should always use equipment properly and wear protective clothing. If dealing with any live animals, provide ethical treatment and appropriate care. |
|
|
Scientist options if experiment fail |
Scientist can revise hypothesis with information gained from experiment and test it again as many times as needed. Results from experiment could lead to answers to different questions or information on a specific topic. |
|
|
Independent and dependent variables |
Independent variable- what is changed by experimenter, it's the cause Dependent variable- what is being measured, it's the effect |
