Biology projects for class 12 topics



Finding good Biology project topics is quite tough than answering the questions. Many students are confuse to select the good biology project topics. It depends on your interest. There are many things in biology

To select good biology project topics you have must follow some rules like
  1. Choose a topic that YOU are passionate about. Make sure to search for a topic that interests you. Follow your professor’s advice, but make your own choices
  2. Investigate old ideas you might have come across during your Master’s studies. Check out old resources you might have used for previous research during your graduate years.
  3. Ensure that no one else has already carried out a similar research.
  4. Your topic should be something your adviser finds interesting, 
  5. Find a topic you like to read about and develop interesting questions that lead to testable to you.
  6. choose a topic that is different from the rest, as it arouses some interest in the examiner and leaves an overall good impression on him /her.

So here is a list of topics that you might find interesting keeping in view your 12th std project:
