Question

provide an example of the following terms: hypothesis, model, law, principle, theory, case study, descriptive study, observational experiment, manipulative experiment, independent variable, peer - reviewed journal. review question: what are the three essential elements of the scientific method?

Explanation:

• Hypothesis: A proposed explanation. Example: Plants grow taller with more sunlight.
• Model: A representation. Example: A scale - model of the solar system.
• Law: A statement based on repeated observations. Example: Newton's law of universal gravitation.
• Principle: A fundamental truth. Example: The principle of conservation of energy.
• Theory: A well - substantiated explanation. Example: The theory of evolution.
• Case study: An in - depth analysis. Example: A study on a specific rare disease case.
• Descriptive study: Describes phenomena. Example: A study on the behavior of penguins in their natural habitat.
• Observational experiment: Observes without manipulation. Example: Observing bird migration patterns.
• Manipulative experiment: Manipulates variables. Example: Testing plant growth with different fertilizers.
• Independent variable: Variable that is changed. Example: The amount of water given to plants in an experiment.
• Peer - reviewed journal: A journal with expert reviews. Example: "Nature" is a well - known peer - reviewed journal.

The three essential elements of the scientific method are observation, hypothesis formation, and experimentation.

Answer:

• Hypothesis: Plants grow taller with more sunlight.
• Model: A scale - model of the solar system.
• Law: Newton's law of universal gravitation.
• Principle: The principle of conservation of energy.
• Theory: The theory of evolution.
• Case study: A study on a specific rare disease case.
• Descriptive study: A study on the behavior of penguins in their natural habitat.
• Observational experiment: Observing bird migration patterns.
• Manipulative experiment: Testing plant growth with different fertilizers.
• Independent variable: The amount of water given to plants in an experiment.
• Peer - reviewed journal: "Nature"
• Three essential elements of the scientific method: Observation, hypothesis formation, experimentation.
