you can start a science project by explaining What it is your writing about. Remember though, to say it in a formal context. for example e.g..
I am going to explain what yours and my life cycle is and the order it happens in. You always start of in your mother's womb and then...
start it off like that and you are bound to have piled of A+ come flooding to you.
I hope you found this helpfull and remember to give your thanks!
