Project’s name: Greenhouse

Level 7th

Category: Demonstrative

Thematic Area: Environment and Energy


Year: 2012

General objective
Analyze the importance of the greenhouse effect forthe life of human beings.

Specific Objectives

1 - To investigate which is the greenhouse effect.
2 - As the greenhouse effect develops.
3 - Quote what are the benefits for our planet.
4 -Drawbacks for humans.

Hypothesis

To get to reduce global warming must overcome many bad habits that endanger the life of the planet and human beings.

Theoretical Framework
A greenhouse is astructure made of glass or clear plastic, which provides a controlled environment for growing plants indoors.
The Earth's temperature is kept warm by the atmosphere and the gases it contains, so-calledgreenhouse gases (carbon dioxide and water vapor mainly). These gases trap heat from the sun and prevent part of the insolation (amount of solar energy reaching the Earth) is reflected into space. Theaverage temperature of the surface depends on the amount of these gases in the atmosphere, these gases increased resulting in an increase in temperature and a decrease of the gas would cause adecrease in temperature.
Carbon dioxide is the result of breathing and burning lots of fossil fuels (oil, natural gas, coal), with increasing world population of these burn more fossil fuels, and thereforeincreases the amount carbon dioxide. Trees can help reduce the amount of carbon dioxide in the air, as it is used in the reaction of photosynthesis to make food. Deforestation (logging), burning fuelsand increase the amount of carbon dioxide.

Methodological Framework
To conduct this experiment was necessary to perform the following steps:
Material:
1 cup ground
1 medium jar with lid
2thermometers

Procedure:
1. Place the soil into the jar, and drop a thermometer into the jar and cover.
2. Place the jar near a window facing the sun, and the other thermometer near the bottle....
