Many teachers hear about differentiated instruction frequently during professional development, but often we struggle to apply this to our own subject matter. If this sounds like you, then check out Access Center. On this site, you’ll find some tips and examples for various differentiated stratgies, such as choice menus, flexible grouping, tiering, and more. There is even a page for science (woohoo!). The site is geared toward K-8, but this will still give you some basic ideas to work from.
Go here to visit Access Center.

Hello!
I love your blog and will be visiting often. I found you through this post; I’m always interested in how teachers are supporting all students in their diverse classrooms. I also thought I would let you know about a new blog I have up on WordPress called Differentiation Daily: http://differentiationdaily.com/. If you are looking for some posts to “borrow” in your year of blogging (good luck, by the way- very impressive), I have a science post nearly every week. Hope it helps. I will be featuring your site in the near future so thanks in advance. –Paula
