Scientific Method and Inference Concepts

What is the main goal of the scientific method?

• To prove a scientist's initial guess is correct.

• To explain why things happen in the world.

• To create new problems for scientists to solve.

• To make observations without drawing conclusions.

What is the initial step in scientific problem-solving?

• Formulating a hypothesis.

• Conducting an experiment.

• Recognizing the problem.

• Analyzing data.

Before making observations, what should a scientist consider?

• What new equipment is needed for the experiment.

• What is already known about the problem.

• The best way to publish the results.

• How to convince others of their idea.

Which statement best describes an inference?

• A direct observation of an event.

• A conclusion based on observations.

• A random guess about a phenomenon.

• A detailed plan for an experiment.

What is a hypothesis in the scientific method?

• A proven scientific fact.

• A final conclusion drawn from an experiment.

• A testable explanation for an observation.

• A summary of all collected data.

What were the controlled variables in the plant experiment?

• The amount of water and sunlight.

• The type of plant and watering schedule.

• The type of pot, soil, and amount of sunlight.

• The plant's growth rate and leaf color.

In the plant experiment, what was the variable being changed by the experimenters?

• The type of pot used.

• The amount of sunlight received.

• The type of soil.

• The amount of water given to each plant.

Based on the experiment's results, what was the optimal watering schedule for the fig plants?

• No water at all.

• Watering every day.

• Watering three times a week.

• Watering once a week.

What is the purpose of forming a conclusion in the scientific method?

• To state the problem that was investigated.

• To summarize the results and determine if the hypothesis was supported.

• To make a random guess about the experiment's outcome.

• To list all the materials used in the experiment.

How does a hypothesis become a scientific theory?

• It becomes a theory after a single successful experiment.

• It becomes a theory when it is repeatedly confirmed through experimental testing.

• It becomes a theory if it is a popular idea among scientists.

• It becomes a theory if it cannot be disproven.
