What is a project introduction for a school project?

Answer 1

The introduction is where you explain the question you are trying to answer with your experiment.

Does X have an effect on Y?

From there you go on to explain why you would want to answer this question and the reason you chose the methods involved (in contrast to other possible methods you did not test)

A science experiment that does not attempt to answer a question is a pointless show and tell project.

Answer 2

it is about what your project is about

Answer 3

cleanliness
