Final project: in the eyes of an 8 year old

For my final project I would like to do a documentary on my little sister Abari. She is a sassy now 8 year old busy body. The goal of my documentary is to discover what it's like to live in the life of an 8 year old, what do they go through, how do they handle their issues and what excites them. I feel like my sister is a perfect candidate seeing as her birthday party is this Friday. Also because she is extremely accessible. I will film for 4-5 days then I'll take a day to edit. I plan to be done by tuseday and am excited to see how it turns out.
