That is a great idea. I love the thought that our kids can look through them when they are adults and get such a kick from those memories. :)
i wanna have a folder...and just separate them by subject title...so he can easily go thru it and find whatever as the weeks and months and years go by...so like one major one each year with field trips and or a separate one for experiments..
using one binder/folder with dividers will help us both with organising and locating it lol
