What is one of the main goals of science?

• To create fictional stories

• To provide natural explanations for events

• To ignore patterns in nature

• To predict supernatural events

What are the steps involved in the scientific methodology?

• Observing, asking questions, making inferences, forming hypotheses, conducting controlled experiments, collecting and analyzing data, drawing conclusions

• Observing, guessing, forming opinions, conducting random experiments, collecting data, making assumptions

• Asking questions, forming opinions, conducting uncontrolled experiments, analyzing data, drawing assumptions

• Observing, making assumptions, forming hypotheses, conducting uncontrolled experiments, collecting data, drawing conclusions

What do observations generally involve?

• Using scientific instruments

• Using the five senses

• Using mathematical calculations

• Using computer simulations

What is an inference?

• A scientific explanation for a set of observations

• A logical interpretation based on what you already know

• A random guess without any basis

• A proven fact

What is a hypothesis?

• A random guess

• A logical interpretation

• A scientific explanation for a set of observations

• A proven fact

What is a controlled experiment?

• An experiment where all variables are changed

• An experiment where no variables are changed

• An experiment where only one variable is changed, and others are controlled

• An experiment where two variables are changed

What is an independent variable?

• A variable that is observed and changes in response to another variable.

• A variable that is deliberately changed.

• A variable that remains constant throughout the experiment.

• A variable that is not measured in the experiment.

What is a dependent variable?

• A variable that is deliberately changed.

• A variable that remains constant throughout the experiment.

• A variable that is observed and changes in response to another variable.

• A variable that is not measured in the experiment.

What is an experimental group?

• A group where the independent variable is not tested

• A group exposed to the same conditions as the control group

• A group where the independent variable is tested

• A group that is not compared to any other group
