1. Science is a way of learning about the natural world.
The body of knowledge that scientists have is always growing and changing.

2. Thinking Like a Scientist
Some of the skills that scientist use are
posing questions,
making observations and inferences,
developing hypotheses,
designing experiments,
making measurements and collecting data,
drawing conclusions,
and communicating.

3. a. The number of cavities the sixth graders have?
b. The number of people in the sixth graders’ families?
c. The ages of the sixth graders’ mothers?
d. The heights of the sixth graders in inches?

4. Posing Questions
Usually scientific inquiry begins with posing a question or stating a problem.

5. Making Observations and Inferences
Observation involves using one or more of the senses to gather information and collect data.
Data are the facts, figures, and other evidence gathered through observations.
Often a scientist’s observations and data lead to an inference, which is an interpretation of an observation based on evidence and prior knowledge.

6. Developing Hypotheses
Scientists may then develop a hypothesis, a possible explanation for observations or a scientific question.
A hypothesis must be testable.
A hypothesis can be worded as an If…then… statement. For example, you could develop the following hypothesis:
If fertilizer is added to the soil surrounding a tomato plant, then the plant will grow taller.

7. Designing an Experiment to Test a Hypothesis
Variables are factors that can change in an experiment.
Often a scientist changes one variable to test a hypothesis.
This changed variable is called the manipulated (or independent) variable.
A factor that changes because of the manipulated variable is a responding (or dependent) variable.

8. Designing an Experiment to Test a Hypothesis
An experiment in which all variables except one remain the same is called a controlled experiment.

9. Designing an Experiment to Test a Hypothesis
Controlled Variables – variable that are kept the same.
Independent Variables – variable that is being changed.
Dependent Variables – the variable being observed or tested.

10. Making Measurements and Collecting Data
Scientists collect data by measuring and observing.
They use a standard system of measurement called the International System of Units.

11. Interpreting Data
Data must be organized and interpreted.

12. Drawing Conclusions
This leads scientists to draw a conclusion, or sum up what they have learned from the investigation.

13. Communicating in Science
Finally, scientists communicate their results and conclusions to others.
Conclusions often lead to new questions and new experiments.

15. Scientific Theories
A scientific theory is a well-tested concept that explains a wide range of observations.
Sometimes, further testing can prove a scientific theory to be faulty.
In this case, scientists either revise or abandon the theory.

19. Laboratory Safety
A very important part of a scientific experiment is observing safe laboratory practices.
In general, laboratory safety means following instructions and making sure you understand all laboratory procedures before getting to work.
                                                    

20. Branches of Biology
Biology explores the structures, functions, and interactions of many living things.
Branches of Biology offer careers such as physician, botanist, marine biologist, emergency medical technician, park ranger, and physical therapist.
