Assignments will be posted on my static pages at the top of the page.  I like this method as it keeps things a little more organized for me.  I also like this as this is how our 7th grade science blog is set up based on our key units for the year.  The 7th grade science teachers set this up two years ago and it is an easy way for us to share labs, activities, websites, and videos that we use in our classroom in an organized way.
