Scientific Method and Theories

The video tutorial explains the scientific method, emphasizing the importance of asking questions, conducting research, formulating hypotheses, and testing them through experiments. It clarifies the difference between hypotheses and theories, using examples to illustrate how scientific thinking is applied in everyday scenarios.

What is the first step in the scientific method?

• Drawing a conclusion

• Asking a question

• Forming a hypothesis

• Conducting research

Which of the following is NOT necessary to do science?

• Curiosity

• Asking questions

• Conducting experiments

• A PhD

Why is skepticism important in scientific research?

• It helps in accepting all claims

• It ensures that only proven claims are accepted

• It allows for faster conclusions

• It reduces the need for experiments

What makes a hypothesis scientific?

• It is always correct

• It cannot be proven wrong

• It is based on a guess

• It can be tested and potentially proven wrong

In the example given, which highway was hypothesized to be the fastest route?

• None of the above

• City streets

• Highway 280

• Highway 101

What was the conclusion of the experiment regarding the fastest route?

• Highway 101 was faster

• Highway 280 was faster

• City streets were faster

• All routes took the same time

What is the main difference between a hypothesis and a theory?

• A hypothesis is a proven fact

• A theory is a guess

• A hypothesis is a testable idea, while a theory is a well-tested explanation

• A theory cannot be proven wrong

How can a scientific theory change over time?

• By being accepted without evidence

• By being proven correct once

• By being ignored

• Through repeated testing and refinement

Which of the following was once a common theory but later proved wrong?

• The Earth is the center of the universe

• The Earth is flat

• All of the above

• The sun revolves around the Earth

What is the current scientific understanding of the solar system's structure?

• The Earth is at the center

• There is no center

• The sun is at the center

• The moon is at the center
