The dependent variable is the variable that is measured or tested in an experiment. It is affected by changes in the independent variable.

The independent variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

A controlled experiment is one in which all variables are kept constant except for the one being tested, allowing for a fair test of the hypothesis.

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

Replicating experiments is important to verify results and ensure that findings are reliable and not due to chance.

Publishing scientific data allows for peer review, validation of results, and sharing knowledge with the scientific community.

A line graph is used to display data points over time or to show trends in data.

Holding variables constant means keeping certain factors the same throughout the experiment to ensure that the results are due to the independent variable.

Sunlight is essential for photosynthesis, which allows plants to make food and grow.

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
