Hypothesis	We believe the acid rain will discolor and deform the objects.  We also think it will kill the plants. We think that the acid rain will evaporate and then fall as rain.
Purpose	We wanted to find out how acid rain effected the earth, and we wanted to have fun doing our science fair project.
Materials	1 terrarium 1 metal cereal bowl  1/4 of a cup of vinegar   1/2 a cup of water   1/8 of a cup of lemon juice   1 brass cup   1 ceramic flower pot   1 bag of grave  1 penny  1 piece of wood  2 pieces of thin glass   1 violet plant   1 green leaf plant   1 wooden board
Procedure	First, we washed out the terrarium with soap, bleach and water.  Next, we sanded off the board the terrarium is standing on.  We put 1/2 of a bag of gravel on the middle of the board.  Next, we carefully set the two plants, a bowl filled with acid water, a piece of wood, a penny, two pieces of thin glass, a ceramic flower pot and a brass cup into the terrarium.  We then observed, once a week on Saturdays, what happened to the objects in the terrarium, over a three week period.
Results	The results that happened to our science project was that almost all of the objects either discolored, deformed or died.  The two plants both wilted, then died.  Both the penny and the brass cup turned a greenish-brownish color.  Parts of the wood broke off. And, nothing happened to the ceramic flower pot, the glass or the gravel.
Conclusion	Our conclusion is that acid rain will have an effect on brass, copper, wood and plants in our environment, but it wonít have an effect on ceramic, glass or gravel. Thus we, as a planet,  may need to look at what it is we are using  as materials to build with.  With the plants being  killed by the acid rain, animals (humans are animals too!) would not have enough oxygen for us to breath and live on.  As we researched we found out that acid rain will not only effect the environment, it will also affect humans as well.  We need to take this matter seriously!  Everyone should be concerned about these results and start now to help clean up our environment from acid rain.
