Scientific Method Day 1

In 1620, The ________ method involved the use of inductive reasoning. Inductive Reasoning is making observations, looking for a pattern in them, and formulating a hypothesis, (theory) based on these observations and patterns

• Newtonian
• Baconian
• Mendelian
• None of the above

All scientific investigations begin with:

• Forming a hypothesis.
• Conducting an experiment
• Observing and asking a question
• Forming a conclusion.

What answer BEST describes the purpose of the scientific method?

• To solve problems and create experiments
• To research new information
• To practice safety
• To become a scientist

A good scientific question needs....(select all that apply)

• An independent variable
• A dependent variable
• To be measurable
• None of the above

Although a hypothesis may be supported by evidence, it can never be proven true beyond all doubt since new data might indicate that the hypothesis does not hold true in all instances.

• True
• False

Forming a hypothesis is an important step in the scientific method. What is the purpose of the hypothesis in an experiment?

• The hypothesis is a possible answer to the question or problem.
• It is a “testable” statement that is either supported or unsupported by the data collected in the experiment.
• It is often in the "If, Then" Statement.
• All of the above

What is a hypothesis?

• An observation
• Something that you know
• An educated guess/answer to your question
• What you keep the same in an experiment

Which is a good example of a hypothesis for the following scientific question? Does playing stressfull video games lead to higher blood pressure?

• Playing stressfull video games gives people higher blood pressure.
• If you have stressfull blood pressure, then you play violent video games.
• If you play stressfull video games you will have higher blood pressure.
• If you play stressfull video games, then you will have higher blood pressure.

Why is the following hypothesis considered a bad hypothesis? "Plants not given fertilizer will grow taller"

• It is not written in the "if" and "then" format.
• The prediction is wrong.
• The independent and dependent variables are in the wrong order.
• This is a good hypothesis.
