Scientific Method, Variables, & Graphing

Front

What is the scientific method?

Back

The scientific method is a systematic process used for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. It typically involves making observations, forming a hypothesis, conducting experiments, analyzing data, and drawing conclusions.

What are variables in an experiment?

Back

Variables are factors that can change in an experiment. They are classified into independent variables (the one that is changed) and dependent variables (the one that is measured).

What is the difference between independent and dependent variables?

Back

The independent variable is the factor that is manipulated or changed in an experiment, while the dependent variable is the factor that is measured or observed to assess the effect of the independent variable.

Front

What is a constant in an experiment?

Back

A constant is a factor that remains the same throughout the experiment to ensure that the results are due to the independent variable alone.

Front

What is the purpose of a control group in an experiment?

Back

The control group serves as a baseline to compare the effects of the independent variable. It is not exposed to the treatment and helps to isolate the effects of the independent variable.

How do you determine the scale for a graph?

Back

The scale for a graph is determined by analyzing the range of data and selecting appropriate intervals that allow for clear visualization of the data.

Front

What is the X-axis in a graph?

Back

The X-axis is the horizontal axis of a graph, typically representing the independent variable.

Front

What is the Y-axis in a graph?

Back

The Y-axis is the vertical axis of a graph, typically representing the dependent variable.

Front

What is a hypothesis?

Back

A hypothesis is a testable statement or prediction about the relationship between two or more variables.

Front

What is the importance of replication in experiments?

Back

Replication is important because it helps to verify results and ensures that findings are reliable and not due to chance.
