Science is great!

Fernando and Oscar are high school students.

They are talking about their science class. They

are amazed by the things they have learned,

Science is based on what is called scientific

method. The scientific method is a process of

experimentation that is used to explore

observations and answer questions. Scientists

use the scientific method to search for cause

and effect relationship in nature. In other

words , scientists design an experiment so that

changes to one item cuse something else to

vary in a predictable way, First they observe a

phenomenon.

These are some examples Fernando and Oscar found in

their general science book.

Conditional Sentences

El uso del condicional significa que una acción depende de otra. Los condicionales se utilizan para hablar sobre situaciones reales o irreales. En general, las frases condicionales llevan la palabra “if” (si).

Ten en cuenta que no existe un tiempo verbal para el condicional en inglés como existe en español. A la vez, se usa el verbo auxiliar “would” para formar el condicional en inglés.

Hay cuatro tipos de frases condicionales y el uso de uno u otro refleja la probabilidad de la acción.

ZERO

CONDITIONAL

Present real conditional or Zero conditional

Is a structure used for talking about things which always happen under certain conditions, also called general truths. It indicates certainty.

For example: What happens when you heat ice? It melts.

Every time you heat ice it melts, So you can say :

If you heat ice, it melts.

This example is based on scientific facts

A general truth can also be something personal or nor necessarily based on science. This is called a personal fact or personal truth.

The important thing about the zero conditional is that the condition has the same result.

If Valeria is close to a cat, she sneezes

This is a general truth for Valeria
