Back

The conclusion summarizes the results of the investigation, stating whether the hypothesis was supported or not based on the data collected.

Front

What does the X-axis represent in a graph?

Back

The X-axis typically represents the independent variable in a graph.

Front

What does the Y-axis represent in a graph?

Back

The Y-axis typically represents the dependent variable in a graph.

Front

What are controlled variables?

Back

Controlled variables are factors that are kept constant throughout an experiment to ensure that the results are valid.

Front

What is a testable question?

Back

A testable question is one that can be answered through experimentation and observation.

Front

What is data analysis?

Back

Data analysis involves interpreting the data collected during an experiment to draw conclusions and make decisions.
