Teoría de la Ciencia

The video tutorial explains the concept of scientific theory, which is a well-tested hypothesis or set of hypotheses that explain phenomena. It distinguishes between scientific theories and laws, using examples like global warming, the Big Bang, and gravity. The tutorial emphasizes that scientific theories are subject to change with new evidence and that they cannot be proven with absolute certainty. Scientists work with accepted theories while remaining open to new ideas. The video concludes by encouraging reflection on whether science can truly prove a theory.

What is required for a hypothesis to become a scientific theory?

• It must be taught in schools.

• It must be published in a scientific journal.

• It must be tested and not disproved by various scientists.

• It must be accepted by the general public.

Which of the following is an example of a scientific theory?

• The law of gravity

• The Big Bang theory

• The description of photosynthesis

• The formula for water

How does a scientific law differ from a scientific theory?

• A law is always true, while a theory is sometimes false.

• A law explains why phenomena occur, while a theory describes them.

• A law describes phenomena, while a theory explains why they occur.

• A law is a hypothesis, while a theory is a proven fact.

What does the law of gravity describe?

• The phenomenon of gravity

• Why objects fall to the ground

• How fast objects fall

• The energy of falling objects

Why can scientific theories never be proven with absolute certainty?

• Because they are based on assumptions

• Because new evidence can always emerge

• Because they are not tested enough

• Because they are only opinions
