Draw a rough sketch that shows the layout of the science room, and make a preliminary plan for the arrangement of the room. Situate the desks in the center of the room in rows. Place several tables and chairs around the perimeter of the room, where you can create learning centers -- each dedicated to a different aspect of science.
Devote each learning center to a particular topic that you plan to cover in class. Include items and activities that engage all five senses. Create an assortment of fragrant herbs in test tubes, and allow your students to learn to identify them by their scents. Include magnifying glasses that allow students to visually examine a variety of objects.
Collect and hang colorful posters around the room to emphasize the topics to be covered. Create colorful bulletin boards on which to display the work of your students and impart age-appropriate information.
Invite your students to bring in items to add to the classroom. Pine cones, feathers, rocks, plants, leaves and other objects from nature often inspire impromptu discussions and add to the learning process.
Build a collection of age-appropriate reading material. Choose fiction and nonfiction selections that are connected to your current topic of study, so you can read them to the class. Display the books around the room on the chalk tray that lines the blackboards or on bookshelves -- presenting the books with their front covers facing forward.
