14. Introduction to the Scientific Method

15. What is Science? Science deals only with the natural world Scientists
The goal of science is to investigate and understand the natural world, to explain events in the natural world, and to use those explanations to make useful predictions.
Science deals only with the natural world
The scientific method has allowed scientists to show that their ideas are clearly supported by observations and data.
Scientists
collect and organize information in a careful, orderly way, looking for patterns and connections between events.

16. Science begins with an observation.
This is the process of gathering information about events or processes in a careful, orderly way.
Data is the information gathered from making observations.

17. The Steps In The Scientific Method
Ask a question
Once scientists have posed a question and formed a hypothesis, they must design and conduct an investigation.
Develop a
hypotheses
Test the hypothesis with an investigation
Analyze the data and draw a conclusion.

18. A hypothesis is a scientific explanation for a set of observations.
A hypothesis must be stated in a way that makes it “testable”. The hypothesis is just a possible answer to a question, and it must be thoroughly tested.
Hypothesis

19. Scientific Method The Scientific Method is:
A series of steps used by scientists to solve a problem or answer a question.
Observation / asking a question
Form a hypothesis
Design a controlled experiment with an investigation
Record and analyze results and draw conclusions.

20. Step 1: Observation / Asking a Question
A problem or a question must first be identified.
How much water can a root hair absorb?
Why does a plant stem bend toward the light?
What effect does temperature have on heart rate?

21. Step 2: Form a Hypothesis
A possible explanation to the question or problem.
It is simply a prediction and has not yet been proven or disproven.
A hypothesis never can be proven true, but it can be supported.
If a hypothesis is supported repeatedly by investigation, it becomes accepted in the scientific community as valid and eventually may be considered scientific theory or law.

22. Step 3: Designing a Controlled Experiment
The factors in an experiment that can be changed are called variables. Some examples of variables would be: changing the temperature, the amount of light present, time, concentration of solutions used.

23. Controlled Experiment:
A controlled experiment works with one variable at a time. If several variables were changed at the same time, the scientist would not know which variable was responsible for the observed results.
In a controlled experiment only one variable is changed at a time. All other variables should be unchanged or controlled.

24. An experiment is based on the comparison between a control group with an experimental group.
a) These two groups are identical except for one factor.
b) The control group serves as the comparison. It is the same as the experimental group, except that the one variable that is being tested is removed.
c) The experimental group shows the effect of the variable that is being tested.

25. Example: In order to test the effectiveness of a new vaccine, 50 volunteers are selected and divided into two groups. One group will be the control group and the other will be the experimental group. Both groups are given a pill to take that is identical in size, shape, color and texture.

26. Describe the control group.
Even though the volunteers are given identical looking pills, the control group will not actually receive the vaccine.
Describe the experimental group.
This group will receive the vaccine
What variables are kept constant?
The size, shape, color, and texture of the pill.
What variable is being changed?
Whether or not the pill contains the vaccine.

27. There are two variables in an experiment:
The independent variable is the variable that is deliberately changed by the scientist.
It is the addition of the vaccine to the pills that were given to the volunteers.
The dependent variable is the one
observed during the experiment.
The dependent variable is the data
we collect during the experiment.
This data is collected as a result of
changing the independent variable.
The observed health of the people receiving the pills.

28. Step 4: Recording and Analyzing Results
The data that has been collected must be organized and analyzed to determine whether the data are reliable.
Does the data support or not support the hypothesis?

29. Step 5: Drawing Conclusions
The evidence from the experiment is used to determine if the hypothesis is proven or disproven.
Experiments must be repeated over and over. When repeated, the results should always be the same before a valid conclusion can be reached.

30. Forming a Theory Theory:
A theory may be formed after the hypothesis has been tested many times and is supported by much evidence.
Theory:
A broad and comprehensive statement of what is thought to be true.
A theory is supported by considerable evidence.

31. Practice Problem: State your hypothesis: Possible answer:
You want to determine the effects of a certain fertilizer on the growth of orchids grown in a greenhouse. Materials that are available to you include: greenhouse, 100 orchid plants, water, fertilizer, and soil. You want to know if the orchids will grow best with a weak concentration of fertilizer, a medium concentration of fertilizer, or a high concentration of fertilizer. How will you design an experiment to test different concentrations of this fertilizer?
State your hypothesis:
Possible answer:
I predict that the orchids will grow best with a medium concentration of fertilizer.

32. How will you set up a controlled experiment?
The 100 plants will be divided into 4 groups as follows:
Group 1: 25 plants will receive plain water.
Group 2: 25 plants will receive a weak concentration of fertilizer.
The plants will be watered daily.
Over a period of a month, the plants will be measured to see which ones grew the tallest.
Group 3: 25 plants will receive a medium concentration of fertilizer.
Group 4: 25 plants will receive a high concentration of fertilizer.

33. Experimental Control Group
What is the control group in this experiment?
The control group consists of the 25 plants that are receiving plain water.
What is the experimental group in this experiment?
The experimental group consists of the 75 plants that are receiving various concentrations of fertilizer.

34. What variables must be kept constant in this experiment?
In a “controlled experiment”, all variables must be kept constant except the one variable that is being changed.
What variables must be kept constant in this experiment?
All plants are grown in pots of equal size.
All plants are grown at the same temperature.
All plants receive the same amount of sunlight.
All plants must receive the same amount of fluid
each day.
What variable is being changed in this experiment?
The variable being changed is the amount of fertilizer received by each group of plants.

35. Is your hypothesis supported or disproved by these results?
After one month of measuring the orchids, the following data is obtained:
Group 1 (Control Group): Grew to an average height of 15 cm.
Group 2 (Weak conc.): Grew to an average height of 35 cm.
Group 3 (Medium conc.): Grew to an average height of 28 cm.
Group 4 (High conc.): Grew to an average height of 10 cm.
Is your hypothesis supported or disproved by these results?
We hypothesized that the orchids would grow best with a medium concentration of fertilizer.
The results do not support this.
The results disprove our hypothesis.

36. What is your conclusion based on these results?
After one month of measuring the orchids, the following data is obtained:
Group 1 (Control Group): Grew to an average height of 15 cm.
Group 2 (Weak conc.): Grew to an average height of 35 cm.
Group 3 (Medium conc.): Grew to an average height of 28 cm.
Group 4 (High conc.): Grew to an average height of 10 cm.
What is your conclusion based on these results?
Orchids grow best with a weak concentration of fertilizer.
At medium to high concentrations, plant growth is inhibited.

37. Terms to Remember
Hypothesis - a statement that uses a few observations - an idea or proposition based on observations without experimental evidence Theory - uses many observations and has loads of experimental evidence - can be applied to unrelated facts and new relationships - flexible enough to be modified if new data/evidence introduced Law - stands the test of time, often without change - experimentally confirmed over and over - can create true predictions for different situations - has uniformity and is universal 

38. GED READY INFORMATION

39. Did You Know?
Students who prepared for the GED test using the official practice test from GED Testing Service pass at a higher rate.
The best way to find out if you are ready for the GED test is to take the GED Ready practice test. The majority of people who score “likely to pass” on the GED Ready practice test, go on to pass the real test in that subject.

40. The GED Ready has the same look and feel as the
real GED test.
The score report tells students if they are likely to
pass or if it’s too close to call and they should keep studying.
The GED Ready is scored on the same day you take the test.
The GED Ready gives each student their own study plan based on the skills he or she needs to work on including specific guidance on what to study in publisher’s test prep materials.
The GED Ready takes about 45 minutes to complete and is available in English and Spanish.
You will receive an Enhanced Score Report that gives you specific pages or chapters in resource materials you need to study to score higher.
