If you are a middle school teacher, then you may have noticed that middle school-aged kids have a very short attention span. In my classroom, I try to “change gears” often to keep the kids engaged and interested. In my 50 to 60 minute class, I try to have at least 4 or 5 different activities to do. I use short, interesting videos to introduce a topic. Middle school-age kids pretend to be so cool, but they enjoy silly animated videos, and I am more than pleased to offer them. Here are a few of my favorite science channels.
