Throughout the years of teaching I have run into some really good sites and interesting things for teachers. Here is a selection for your perusal. This page is dedicated to you guys out there trying to make middle school students interested and engaged in science. Yay science!
I have also included a box on the bottom of each unit page for curriculum specific to that unit so feel free to check those out as well. All of the documents in those boxes are in PDF form, but if you wish for the Word form please email me.
