the Spanish culture is from Spain and there is no Hispanic culture since there are many different countries that speak Spanish and every one of them has a different culture , the food is different , the music even the way they speak the language
Is like you wanted to get info on English culture (which is from England) and you thought that Canadians, Jamaicans, Americans, Bahamians and English people are the same and have the same culture.
I think you should tell your teacher if he/she could let you do a project about a particular Spanish speaking country so you can focus in only one culture it is going to be a lot easier and you can do a better job. good luck.
