Sci Fi Example Blog Post

Name and Author of Fantasy Book:
Ender's Game by Orson Scott Card

Three Fantasy Elements:
Book is set in the Earth's future
Book contains alien creatures that Ender must defeat
Book is set on a spaceship

Sci Fi Element I Would Add:
I would add another separate space command school of students who are also training to keep earth safe.  The command school develops and utilizes different scientific techniques to defeat the alien threat that Earth is facing.  The command school would have to go up against Ender's command school in order to determine which school would ultimately battle to keep Earth safe (since they don't share the same strategy or visions for how to do this).   Ender would befriend a student in the other command school and ultimately team up with him to defeat Earth's alien threat.
