There are countless topics of research that would be great ideas for a research paper, such as alcohol abuse in teenagers and current political issues, including immigration and climate change. Other topics of interest may include America's dependency on fast food or the argument over whether to say the Pledge of Allegiance in schools.
The topic of a research paper depends largely on where a student's interests lie. A student who loves animals may want to write on animal rights and vegetarianism. Another topic may address whether animal abuse should be punished as a felony. A student more interested in history may want to research the Holocaust, while a student more involved in current events may want to research Al-Qaida or terrorism.
