Pre-Google Docs Lesson Plan

I've been working really hard on a Science lesson plan for my 3rd grade class and I will be using Google Docs in this lesson. The students will be learning about the food chain and working in groups to help put the correct order of the food chain together, then they will answer some higher-thinking questions. On Google Docs, each group will have a computer to use, and on the program, each student in the group will take turns writing the correct animal in the food chain. They will each also type up an unanswered question they may have or a detail they learned about the lesson that they would like to share. I'm a bit nervous to use the Google Docs in my lesson because I'm not very good at using technology, so I'm really hoping that the lesson goes good and that the students will learn what they need to know.
