Definition of: Scientific Method:
A process used to solve a scientific question that includes the following steps; observation, hypothesis, experiment, data collection, analyze the data, and form a conclusion
A testable statement based on observations that could be the solution to a problem
What is kept the same in an experiment in order to compare the results to the variable that is tested and measure change
A well tested explanation to a problem that unites many different experiments and can be revised as new information is found
Definition of: Investigation
A well tested explanation to a problem that unites many different experiments and can be revised as new information is found.
A testable statement based on observations that could be the solution to a problem
What is kept the same in an experiment in order to compare the results to the variable that is tested and measure change
When the scientific method is used as a process to figure out the answer to a question testing one variable at a time
Definition of: Qualitative Data
Data that is measurable or in numbers
Data that is descriptive and you can use your 5 senses to describe
Definition of: Quantitative Data
Data that is measurable or in numbers
Data that is descriptive and you can use your 5 senses to describe
Definition of: Hypothesis
When the scientific method is used as a process to figure out the answer to a question testing one variable at a time
What is kept the same in an experiment in order to compare the results to the variable that is tested and measure change
A testable statement based on observations that could be the solution to a problem
A well tested explanation to a problem that unites many different experiments and can be revised as new information is found
Definition of: Theory
A testable statement based on observations that could be the solution to a problem
When the scientific method is used as a process to figure out the answer to a question testing one variable at a time
A well tested explanation to a problem that unites many different experiments and can be revised as new information is found
What is kept the same in an experiment in order to compare the results to the variable that is tested and measure change
Definition of: Variable
What changes in an experiment depending on the hypothesis
What is kept the same in an experiment in order to compare the results to the variable that is tested and measure change
Definition of: Independent Variable
The variable that is being tested in an experiment.
The variable that changes in response to the independent variable
Definition of: Dependent Variable
The variable that is being tested in an experiment.
The variable that changes in response to the independent variable
Definition of: Control
What is kept the same in an experiment in order to compare the results to the variable that is tested and measure change
A well tested explanation to a problem that unites many different experiments and can be revised as new information is found
A testable statement based on observations that could be the solution to a problem
When the scientific method is used as a process to figure out the answer to a question testing one variable at a time
This part of the experiment serves as a basis of comparison; the one variable being tested has been omitted.

Variables
An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...
The type of plant
The amount of sunlight
The type of music
The type of liquid
A student wants to test the effects of type of exercise on heart rate. What is the dependent variable?
heart rate
type of exercise
amount of exercise
time of day exercise occurs
An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, what are the controlled variables?
Type of plant, amount of music, and sunlight
Water, apple juice, milk
Plant growth
All hypothesis are accepted.
True
False
In order to be accepted, a scientific theory must be
widely tested and supported by extensive data
based on the results of a single experiment
controversial and cause debate
in line with all previous historical ideas
Which is true about hypothesis?
A. It may reject or accepts your prediction.
B. It is an educated guess or possible answer to the question.
C. It summarizes the result on the experiment.
D. It is the final answer to the question
The summary at the end of an experiment that explains the results.

An experiment was carried out to determine whether drinking caffeinated soda increases pulse rate. The pulse rates of two groups of people at rest were measured. Group A was then given caffeinated soda and group B was given caffeine-free soda. One hour after drinking the soda, the pulse rates were measured. The participants in the experiment were all the same age, and they were all given the same amount of soda. The dependent variable in this experiment is the
type of soda given to each group
amount of soda given to each group
pulse rate of each group
age of participants in each group
