STANDARD 1

Propose predictions related to some energy sources, taking into account the relationships between some variables involved in their functioning.

Problem situation :

In this city, the use of oil is very common. It can cause air pollution during its use. The inhabitants of the city need to use a new source of energy. (see picture)

Propose a prediction related to a form of clean energy that could be used, taking into account one advantage and one disadvantage of its use.

STANDARD 1

Propose predictions related to some energy sources, taking into account the relationships between some variables involved in their functioning.

Problem situation 1:

In a region, the main source of energy are fossil fuels, and they are generating a lot of air pollution problems.

According to the characteristics of the area shown in the picture, propose a prediction related to a form of clean energy that could be used, taking into account one advantage and one disadvantage of its use.

STANDARD 2.

According to the problem situation, explain the solution related to the Energy sources and the impact of each one of them on the environment.

Problem situation 1:

The use of this source of energy provides different advantages such as: they are easily transported for their various uses by train, tanker or pipeline, also the cost of electricity produced by using this energy, is relatively inexpensive.

1. According to the picture, what type of energy is it?

2.Explain two negative effects on the environment of the use of this energy.
