1. Scientific Inquiry

2. Biblical Reference
Great are the works of the Lord, studied by all who delight in them.
Psalm 111:2

3. What is Science?
Science is the investigation and exploration of natural events and of new information that results from those investigations.
Using reasoning, creativity, and skepticism to solve problems.
People from many backgrounds, interests and talents have contributed to science over thousands of years.

4. Three Branches of Science
Life Science – the study of all living things
Earth Science – the study of the Earth and the forces that shape the Earth’s surface
Physical Science – the study of chemistry and physics

5. Life Science
Study of all organisms and the many processes that occur in them.
Questions from a Life Scientist:
How do plant and animal cells differ?
How do animals survive in the desert?
How do viruses spread?

6. Earth Science
Study of the processes that occur on, deep within and above the Earth
Questions from an Earth Scientist:
What are the properties of minerals?
How do volcanoes form?
How is energy transferred?

7. Physical Science Study of Matter (Chemistry) and Energy (Physics)
Questions from a Physical Scientist:
What happens to energy during chemical reactions?
How does gravity affect roller coasters?
What are protons, neutrons and electrons?

8. Branches of Science

9. Scientific Inquiry

10. Ask Questions
Asking a question is often the first step in using scientific methods.
Asking a question usually results from making many observations, using one of more of the five senses.

11. Form a Hypothesis
After scientists ask a question, their next step is usually to form a hypothesis.
A hypothesis is a possible explanation or answer to a question.
A good hypothesis is a testable idea that leads to scientific investigation.
A prediction is a statement of what will happen next in a sequence of events

12. Test the Hypothesis
After scientists form a hypothesis, they usually test the hypothesis to find out if it is a reasonable answer to their question.
If the prediction is not confirmed, the hypothesis might need revision

13. Organize and Analyze Data
Analyzing results by using tables and graphs helps scientists understand relationships between the data.

14. Organize and Analyze Data
Scientists must determine whether inferences or conclusions can be made from the data.
An inference is a logical explanation of an observation that is drawn from prior knowledge or experience.
Analyzing data from repeated tests can help scientists determine if their data are accurate and reproducible.
Data are reproducible when you get similar data from many tests.
If the hypothesis is not supported, it may have to be modified.

15. Draw Conclusions
After scientists analyze the results, they draw conclusions about whether their hypothesis was supported.
Valid conclusions can only be obtained with reproducible data.
Data are considered reproducible when scientists get similar data from many repeated tests.
Reproducible data helps scientists make sure that the results of their experiment were not an accident

16. Communicate the Results
After drawing conclusions, scientists often communicate their results.
When scientists communicate their results, it allows others to continue the investigation.
Results can be communicated through scientific papers, presentations, and the Internet.

17. Results of Scientific Inquiry
Scientists perform scientific inquiry to find answers to questions.
Who, what, when, where, why or how
The practical use of scientific knowledge, especially for industrial or commercial use is technology.

18. New Materials & Technology
Corporations, governments and universities spend millions of dollars to design new materials and technologies.
Using the Scientific Inquiry Cycle

19. New Objects & Events
NASA’s Hubble Telescope has identified several thousand new planets and galaxies.
Scientists discovered bacteria in a lake 60-feet below the ice on Antarctica.
Scientific research indicates that stem cells can be used to treat and cure many diseases.

20. Scientific Theory and Law
A scientific theory is an explanation of observations or events based on knowledge gained from many observations and investigations.
A scientific law describes a pattern or an event in nature that is always true.

22. Scientific Theory and Law
Critical thinking is comparing what you already know with the information you are given in order to decide whether you agree with it.

23. Scientific Theory and Law
To prevent bias in an investigation, sampling, repetition, and blind studies can be helpful.
Bias: Intentional or unintentional prejudice towards a certain outcome.
Sampling: A small, random representation of the whole population
Repetition: Experiments are conducted multiple times to ensure the results are valid.
Blind Studies: The investigator, subject or both do not know which sample they are testing.

24. Scientific Theory and Law
Questions about personal opinions, values, beliefs, and feelings cannot be answered scientifically.
Scientists follow safety procedures when they conduct investigations.
Ethics are especially important when using living things during investigations
