The community problem we worked with was the lack of electrical safety in the district of La Molina.  After talking with Civil Defense of La Molina we found out that a recent law states that groundings must be installed in every place where electricity is present.  The consequence of this law not being enforced is that half of the deaths of domestic accidents are due to electricity, summing up to a statistic of 14.5 thousand deaths per year. Many schools were requesting the installation of groundings, but the people in charge of implementing that need, didn’t have the tools, knowledge or money to fulfill their needs. 

          After further discussing our ideas with Civil Defense we realized that the lack of groundings was a huge issue in the district of La Molina. Before performing further actions, we investigated about the topic and the project’s feasibility.  To learn about groundings, we visited many web pages and talked to professionals. Grounding is any metal conductor that has contact with the ground, which closes an electrical circuit using the Earth.  It is buried underground in the land with the lowest resistance possible.  Resistance is a force that acts against electricity, this means that the lower the resistance, the easier it is for electricity to travel.  Any metal including humans have a resistance.  The copper in the grounding is connected to the main electric box of a building so when there is a short circuit, the electricity has contact to the copper and it can be conducted through it to the ground instead of through humans.  By instinct, the electricity will choose the metal that conducts it to the ground with the less resistance.  So that this is possible, the grounding must have a maximum resistance of 25 ohms because it is less than the resistance of humans, animals and electronic devices. 

          Continuing our investigation, we attended talks along with the engineers of the Municipality delivered by professional engineers that regarded the use of an electrometer to measure the resistance of the ground.  Moreover, we investigated the budget of our project by measuring the resistance of the ground, which determines the cost of the grounding, the less resistance, the cheaper the cost. We measured in five schools with the help of professional engineers in the presence of workers from the Municipalidad.
