The short answer? No. You don’t NEED to decorate your high school science classroom. BUT… you’re room will look dull if you don’t. I don’t know where this idea came from that high school classrooms need to be boring. Big kids need stimulation too! That’s not to say you must go all out like those colorful elementary school teachers. You can if you want to, but that is a lot of work. You only need to do a couple of things to give your classroom some oomph!
