2. Branches of Science

3. Branches of Science Physical Science:
Physics: the study of matter and energy and their interactions
Chemistry: the study of matter and its interactions
Astronomy: the study of celestial bodies and the universe as a whole
Earth Science
Geology: the study of materials, processes, and history of earth
Oceanography: The study of the oceans (the geological, chemical, and biological aspects)
Meteorology: The study of the atmosphere
Life Science
Biology: the study of life
Behavioral Sciences: the study of human and animal behavior
Social Sciences: the study of human society and social relationships

4. Scientific Inquiry
Scientific Inquiry refers to the diverse ways in which study the world and propose based on the derived from their work.
Scientific inquiry involves:
questioning, observing and inferring, experimenting, collecting and organizing data, finding evidence and drawing conclusions, repeating the experiment several times, peer review.
Scientists, natural, explanations, evidence

5. Scientific Method
The Scientific Method is a set of steps that scientists follow to solve a problem or answer a scientific question.

7. Hypothesizing
A prediction is
Example:
A hypothesis is:

8. Inferences An inference is Observations Inferences
Examine the picture at your table. Complete the chart below with observations and inferences about the scene or event.

9. Cause and Effect Relationships
In a cause-and-effect relationship,
Examples (think of ones that are in the text):
Cause: Effect:
Some events are coincidental and are not the result of a cause-and-effect relationship. How would a scientist prove that an event was truly caused by another event?

10. Scientific Bias
Bias is
Sources of bias:

11. Faulty Reasoning Faulty reasoning is
Why is having more than enough data better than not having enough data?

12. Fact vs. Opinion A fact is An opinion is
Write one sentence that represents a fact about the Martha’s Vineyard.
Write one sentence that represents an opinion about the Martha’s Vineyard.

13. Variables Dependent Variable: Independent Variable: Control:
Constants:
Scenario 1: Imagine you are conducting an experiment to test the effect of temperature on the growth of a tomato plant.
Dependent variable = Plant Growth (Height in cm)
Independent variable= Temperature differences
Control = Tomato plant at room temperature
Constants = same type and size of tomato plant, same type of soil, same amount of water added, same size pot, same amount of sunlight, measurements are taken at the same time of day.

14. Variables
Scenario 2: Imagine you are conducting an experiment to test the effect of wheel size on the speed of a toy car as it rolls down a ramp.
Dependent variable =
Independent variable=
Control =
Constants =
