Answer 2

It is from net.

Introduce yourself. "Hello, my name is _____________."

Give the title of your project.  "The title of my project is__________."

Explain the purpose of your project.  "The purpose of my project is_________."

Tell the judges how you got interested in this topic.

Explain your procedure. "The procedure I followed was________."

Show your results.  If you have charts, graphs, or a notebook, show them to the judges and explain them.  If results are shown on your backboard, point them out.  

List your conclusions.  Explain what you have proven.  If you think that you had some problems or error in your experiments, don't be afraid to admit these.

Tell the judges what you might do in the future to continue your experimentation.  What would you have done differently if you were to do the project again.

Of what importance is your project to the world?  Explain any applications of your study.

"Do you have any questions?"  If you do not know the answer to a judge's question, then say, "I'm sorry,  I don't know the answer, but I think the answer is___________."   Do not "fake" like you truly know an answer when you really don't.  If a judge is asking a question, then he / she most likely knows the real answer.  

Thank the judges.
