i'm a student of class XII & i need to submit a biology investigatory project (based on any topic from class 12 c.b.s.e syllabus) for my board exams. I can't think of any topic. i am too confused. PLZ help me by giving some ideas on what to do, and how should i proceed. It should not be too high-standard project and i don't need to make a working model or presentation. Just some details such as graphs etc and a written article on the topic will do. plz help. its urgent.

you can do something related to human body or effects of environmental degradation on human body such as cancer etc. caused by UV rays.

I would recommend creating a closed ecosystem by putting together a self sustaining aquarium in which a fish can survive indefinitely because of the various trophic levels provided.

One such experiment is detailed here:

This would fit in with the class 12 c.b.s.e. syllabus through Unit IV: Ecology and Environment. Be sure to include documentation of the organisms and their required environments (air, water, soil, biota, temperature and light, range of tolerance etc.), as well as levels of organization (species, community and ecosystem) and even ecological interactions. You can provide charts showing energy flow in the system, as well as decomposition and nutrient cycling, and speculate on potential effects of environmental pollution or even environmental changes such as global warming (what happens to the closed ecosystem if the temperature raises?).

You can also include taxonomic data on all of the organisms you include in the ecosystem.

Plus, you get a pretty little aquarium with a live fish in it to present as part of your project, which should be worth a few bonus marks.

Good luck!

You do realise that every school board and every state and every country has its own biology curriculum, right?

YOU need to tell US what topics "class 12 c.b.s.e syllabus" covers before anyone outside of your county has a clue what you are talking about.

Since I don't know what was in your class 12 syllabus, I can't help you.
