The Scientific Method

▪ Scientific method• the process scientists use to investigate a

problem, question, and/or observation

Steps in the Scientific Method

I. Making Observations and Asking Questions (leads to a problem to investigate)

II. Developing a Hypothesis

III. Doing the Experiment (includes identifying variables, constants, and control group and writing a procedure)

IV. Collecting and Analyzing Data

V. Forming a Conclusion

VI. Communication

The Scientific Method: Making Observations– An observation is when you

use your senses to obtain information.

– There are 2 types of observations:

• Quantitative: involve numbers and measurements

• Qualitative: use your 5 senses

1.3

The Scientific Method: Making Observations

Observations vs. Inferences

▪ Inference: a logical explanation for an

observation; not a fact

▪ Can only be used in the conclusion of a lab

1.3

Observation

• That plant is extremely wilted.

Inference

• That plant is extremely wilted due to a lack of water.

Observation

• The car didn't turn on when the key was turned.

Inference

• ????

There are two footprints.

The footprints are different shapes.

The footprints are different sizes.

Each footprint has a longer middle toe.

One footprint is narrower than the

other.

There are two animals in this

picture.

Making Observations & Asking Questions

– Observations and inferences

lead to questioning

• Which brand of trash bag

holds the most mass?

• Which brand of toilet paper is

the strongest?

• Which brand of paper plate

will hold the most mass?

• Which brand of nail polish will

last the longest?

1.3

The Scientific Method: Developing a Hypothesis

• Hypothesis

– An attempt to answer and explain an

experimental problem, question, and/or claim

– written as an “if…then…because...” statement

• Example: If I put more weight on the pirate ship

ride, then it will slow down because the extra

weight will cause it to not flow as freely.

UNDERSTANDING

sensing another's emotions and feelings,and taking a genuine interest in them and their concerns


Listening well to what others have to say

Showing sensitivity to what someone has to say

Imagining yourself in the position of another's perspective

Remaining sincere (displaying genuine feelings; not "fake")

Knowing that you do not need to agree, but you need to recognize another point of view and accept that it is different than your own

The Scientific Method: Designing the Experiment

• Experiment

– a scientific procedure used to make a discovery,

test a hypothesis, or demonstrate a fact or claim

• Variables

– Factors that change in an experiment

• Groups

– The people or things tested in an experiment

1.3

Variables

• Independent variable:– The factor that the experimenter changes during the

experiment; if you are the experimenter you say it’s the variable “I” change; follows ‘if’ in a hypothesis• Example: If I change the weight in the pirate ship ride…

• Dependent variable:– The factor that changes in response to the independent

variable; experimenter makes observations of this variable; follows ‘then’ in a hypothesis• Example: …, then the number of swings will reduce.

• Constants

– Factors that stay the same throughout the entire experiment• Example: length of pendulum’s swing, height at which

pendulum is dropped, person who drops pendulum

Groups• Control group

– The group of subjects (people or things) that is used as a comparison, which will help us to determine the effect of the independent variable

• Example: A pirate ship that has NO weight in it will help us to determine how weight influences the number of swings.

• Experimental group

– The group of people or things that is directly influenced by the independent variable

• Example: The pirate ships with weight in them.

Doing the Experiment

• Procedure: step-by-step directions on how to do the experiment

• Experiments require many trials to improve accuracy

– Trials: Repetitions of testing during the experiment

Scientific Method: Collecting Data

• Data: recorded observations made during an experiment; can be qualitative and quantitative– Organized in a data table: a visual display of data

using rows and columns; typically organized by trials (repetitions during the experiment)

Favorite Animals

Micah asked all of his classmates what their favorite animals are. He found that 12 students liked dogs, 5 students liked cats, 3 students like horses, and 1 student liked bearded dragons.

Scientific Method: Analyzing Data

Scientific Method: Writing a Conclusion

• Conclusion:

– Completed at the end of an investigation

– Summarizes the purpose and the results of the investigation

– Makes recommendations for future testing

Let’s put our knowledge of the Scientific Method to a realistic

example that includes some of the terms you’ll be needing to use and

understand.

Making ObservationsJohn watches his grandmother

bake bread. He ask his grandmother what makes the

bread rise.

She explains that yeast releases a gas as it feeds on sugar.

Initial Observation →Problem/Question

John wonders if the amount of sugar used in the recipe will affect the size of the bread loaf?

Developing a Hypothesis

John researches the areas of baking and fermentation and

tries to come up with a way to test his question.

He keeps all of his information on this topic in a journal.

Developing a HypothesisAfter talking with his teacher

and conducting further research, he comes up with a

hypothesis.

“If more sugar is added, then the bread will rise

higher.”

Doing the Experiment: Identify the Independent Variable

The independent, or manipulated variable, is a factor that’s intentionally varied by the experimenter.

Independent variable: The amount of sugar

John is going to use 25g., 50g., 100g., 250g., 500g. of sugar in his experiment.

Doing the Experiment: Identify the Dependent Variables

The dependent, or responding variable, is the factor that may change as a result of changes

made in the independent variable.

Dependent Variable: the size of the loaf of bread

Doing the Experiment: Procedure/Materials

His teacher helps him come up with a procedure and list of needed materials.

• The materials list must be VERY complete.

• How much of each material will be used in the experiment (25-mL of water or 250-mL of water)

• The size of all equipment (ex 25-mL beaker or 250-mL beaker)

• Every step of the experiment is included

• Each step is short

Then she discusses with John how to determine the control group.

Doing the Experiment: Identify the Control Group

Remember: In a scientific experiment, the control is the group that serves as the

standard of comparison.

The control group may be “no treatment” or an “experimenter selected” group.

Doing the Experiment: Identify the Control Group

Because his grandmother always used 50g. of sugar in her recipe, John is

going to use that amount in his control group.

Doing the Experiment: Identify the Constants

John’s teacher reminds him to keep all other factors the same so that any observed

changes in the bread can be attributed to the variation in the amount of sugar.

What would be some constants for John’s experiment?

Doing the Experiment: Identify the Constants

They might include:1. Other ingredients to the bread recipe2. Oven used3. Rise time4. Brand of ingredients5. Cooking time6. Type of pan used7. Air temperature8. Humidity where the bread was rising9. Oven temperature10. Age of the yeast…etc.

Doing the Experiment: Procedure

John writes out his procedure for his experiment along with a

materials list in his journal. He has both of these checked by his teacher where she checks

for any safety concerns.

Trials

Trials refer to replicate groups that are exposed to the same conditions in an

experiment.

John is going to test each sugar variable 3 times.

Collect and Analyze Results

John comes up with a table he can use to record his data.

John gets all his materials together and carries out his experiment.

Trials

Control group

Collect and Analyze Results

John examines his data and notices that his control worked

the best in this experiment, but not significantly better

than 100g. of sugar.

Conclusion

John’s hypothesis is unsupported so John rejects his hypothesis, but decides to re-test using sugar

amounts between 50g. and 100g.

ConclusionJohn finds that 70g. of sugar

produces the largest loaf.

Communicate the Results

John tells his grandmother about his findings and prepares to

present his project in Science class.
