Spirit Week and Weekly Themes for our Homeschool (Brainstorm Activity)

I just made this form and printed it out. We're going to brainstorm some ideas for weekly themes this school year. I don't mind if we only have one week of the month dedicated to a theme, the idea is to have us work together and think of something we can look forward to and plan for together. 
I want to propose a spirit week in September or October. I like the idea of having the kids feel proud of what we're accomplishing as homeschoolers. I don't know of a better way to create a visual than have a crazy hair day or pajama day, of course! 
I want the kids to be excited, all year long, for what's to come for our homeschool journey. We're stuck with each other, we should have fun! 

Some ideas I've come across are:
