Scientific Method and Experimental Design

To make the experiment more complex

To ensure the experiment is quick

To reduce the number of trials needed

To isolate the effects of the independent variable

They should be based solely on data

They should be derived from assumptions

They should be influenced by societal norms

They should be based on personal opinions

To make the data more interesting

To ensure the integrity of the research

To fit the data into a desired hypothesis

To simplify the analysis process

To increase the complexity of the experiment

To make the experiment more expensive

To reduce the time needed for the experiment

To provide more supporting evidence for hypotheses

They should be discarded immediately

They should be kept unchanged

They should be modified based on the data

They should be ignored

To make the experiment more challenging

To ensure results are consistent and reliable

To reduce the number of trials needed

To increase the number of variables tested

To introduce new variables

To serve as a baseline for comparison

To complicate the experiment

To ensure all variables are tested

Designing an experiment

Formulating a hypothesis

Identifying a problem or question

Collecting data

Life can arise from non-living material

The Earth is the center of the Universe

All living things are made of cells

The sun revolves around the Earth
