Need help writing a science research paper

Please try to help to the best of your abilities. I have tried to get help many places, and they didn't do well.

This is due tomorrow so please try to give me as much information as you can.

Basically, I have a science research paper due tomorrow. My topic is one if metered dose inhalers deliver consistent amount of medication.

I need to write an introduction for that, and really am confused and have no idea where to start.

Here are the guidelines: https://docs.google.com/viewer?a=v&...kb3VibGVvc2NpZW5jZXxneDo3MjY0OThiMzk0MjQxN2Ux

Please scroll down to page 2, and read where it says 'INTRODUCTION.'

I need help with the introduction. I mean, if you can also state how this is helpful to me and or people around me, please state that as well.

I just need as much help as I can get, I have many things due tomorrow and have been working this whole weekend.

Thanks.
