The Scientific Method
|
Problem-solving procedures to form a hypothesis, an appropriate experiment to test the hypothesis, the collection and analysis of data, and drawing conclusions. |
|
|
Independent Variable
|
The one factor that can be changed in an experiment. This is the factor that is changed/tested to see if the outcome of the experiment will be altered. For example: If you want to see if the amount of water given to a plant will affect the height of the plant, the height of the plant is the outcome and the amount of water given is the independent variable. |
|
|
Dependent Variable
|
This is a value or factor that changes as the result of the independent variable. It is DEPENDENT on the independent variable. For example: If you want to see how giving plants different amounts of water might affect how high they grow, the heights of these plants are the dependent variable. The height is DEPENDENT on the amount of water given (the IV).

|
|
Control
|
This is the part of the experiment not being tested or "experimented on". Experiments must a have a control so that there is something to compare the results of the experiment to. If you are manipulating how much water you are giving plants to see if height is affected, the control group must have a constant amount of water for the entire experiment. This way plants that start receiving less or more water can be compared to the control. |
|
|
Bias
|
When an experimenter lets their opinions, predictions, or beliefs influence the outcome of the experiment. Bias can lead to false outcomes and results. |
|
|
Confounding Variable
|
An unintentional factor in an experiment that influences the outcome of an experiment. Confounding variables can be outside the experimenters control and cause false results. |
|
|
Hypothesis
|
A statement or idea that can be tested using an experiment. |
|
|
Observation
|
The gathering of information about a phenomena that helps formulate a hypothesis. |
|
|
Data
|
Can be quantitative or qualitative. Gathered from doing an experiment. |
