Three-ring Binder: Either a binder for Science alone or a divided Science section in a morning or afternoon classes binder. (A single binder for the entire day tends to become disorganized quickly.) Dividers with pockets are recommended. Students will need some sort of pocket to hold small pieces of paper. Pencils are used more frequently than pens. Both are necessary. Lined paper Highlighters (at least one) Colored pencils Calculator 3 x 5 index cards for flash cards
