Science: The Law, The Theory, and The Investigation

What is the primary goal of scientific investigations?

• To develop scientific laws and theories

• To manipulate variables

• To perform experiments

• To use microscopes

Which tool might a biologist use to study cells?

• Microscope

• Rock hammer

• Telescope

• Seismograph

What is a hypothesis in scientific research?

• A testable prediction or explanation

• A description of a natural law

• A consistent pattern in nature

• A well-supported explanation

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

• To serve as a baseline for comparison

• To receive the experimental treatment

• To manipulate the independent variable

• To measure the dependent variable

What is the difference between a scientific law and a theory?

• A law describes patterns; a theory explains phenomena

• A theory becomes a law over time

• A law is a testable prediction; a theory is not

• A theory is constant; a law can change

Why is repetition important in scientific experiments?

• To ensure results are accurate and consistent

• To manipulate variables

• To develop new hypotheses

• To describe natural laws

What is the purpose of replication in scientific research?

• To validate findings and identify biases

• To change the independent variable

• To measure the dependent variable

• To develop scientific laws
