Método científico: definiendo un problema o pregunta

The video discusses how scientists tackle unsolved problems by starting with questions. It uses the example of saltwater and freshwater freezing points to illustrate how observations lead to scientific inquiries. The video emphasizes the importance of defining problems and asking the right questions in scientific research.

Which of the following is NOT mentioned as an unsolved problem scientists are working on?

• Exploring outer space

• Finding cures for diseases

• Developing more fuel-efficient cars

• Predicting earthquakes

Which of the following is a characteristic of scientific research?

• It is only conducted in laboratories

• It begins with a problem or a question

• It always provides immediate solutions

• It is only about physical sciences

What is the main difference observed between saltwater puddles and freshwater ponds in winter?

• Saltwater puddles are larger

• Saltwater puddles do not freeze

• Freshwater ponds are warmer

• Freshwater ponds are saltier

Why do scientists spend a lot of time defining a problem?

• To publish more papers

• To ask the right question

• To ensure they have enough funding

• To avoid making mistakes

What is the scientific question derived from the observation of water freezing?

• Why do freshwater ponds have more fish?

• Why does saltwater evaporate faster?

• What causes freshwater to freeze at a higher temperature than seawater?

• How does temperature affect water density?
