Método científico: comprobando la hipotesis

The video tutorial explains the concept of experiments, highlighting how they are used to test hypotheses. It provides personal examples of experimentation in everyday life. The tutorial then focuses on controlled experiments, defining them as tests where one factor is varied while others remain constant. The video concludes with a detailed design of an experiment using saltwater as the variable, demonstrating how to set up controlled and experimental systems.

What is an example of an experiment you might have done without realizing it?

• Reading a book

• Learning to speak

• Cooking a new recipe

• Watching a movie

What is the main purpose of a controlled experiment?

• To test multiple factors at once

• To observe natural phenomena

• To test one factor at a time

• To prove a theory

In a controlled experiment, what is the term for the factor that is being tested?

• Hypothesis

• Constant

• Variable

• Control

What is the role of the controlled system in an experiment?

• To introduce new variables

• To serve as a comparison

• To change the outcome

• To confuse the results

In the salt water experiment, what remains the same in both systems?

• Amount of salt

• Type of container

• Position in the freezer
