If you need help creating this assignment you could write it kind of like this (Note, I can't do the whole assignment, but I can give you an example):
Make sure you first do an introduction before beginning: Hello! I'm a water molecule, and you are about to go on an incredible journey that my friends and I do all the time!
Make sure it's in order:
You don't want to go from evaporation to another cycle that isn't next! Like, say there are three people in line and you're introducing them, you wouldn't skip over someone!
Of course, make sure your spelling, grammar, and punctuation is correct (Grammarly is a great checker for this)
And: Act like you ARE a water molecule! Make it sound real and exciting! Don't just say "This is evaporation, where water is taken from blah blah blah..." say it excitingly like "And now we are at the next part of our crazy journey! This is evaporation! What happens here is so cool..." ext...
Hope this helps you!!!
