What does introduction in a science project mean?

Answer 1

The introduction is where you tell the reader (or the teacher or the judges) what

the question was that you investigated, and what answer you found. It can also

include a very brief description of how you investigated it, but that can't be more

than one single sentence.

If you look at the whole project from beginning to end, it looks like this:

Introduction:

In the introduction, you very briefly describe what you're about to tell them

in the main body.

Main Body:

In the main body, you tell them what question you studied, how you studied it,

and what answer you discovered.

Conclusion:

In the conclusion, you very briefly describe what you have just told them

in the main body.
