A great way to display information is to use cardboard "Science Project" display boards. You can find them at any office supply store, Walmart, Target, KMart, etc. Use them to display center materials, an author spotlight, a poet of the week, science experiments, current events, or basically anything else you wish to have in your classroom. Your students will enjoy the visuals and it is a great way for you to keep things organized for future use. You can just fold them up and file them away in a cabinet.
