8 1/2 x 11" posters for 4th grade science common core learning goals. Divided into subject matter (i.e. Earth in Space & Time, Earth Structures, Properties of Matter, Changes in Matter, Forms of Energy, Energy Transfer and Transformation, Motion of Objects, Heredity and Reproduction, Interdependence). Each poster lists corresponding standard. Some standards are combined. I keep these in sheet protectors in a binder so I can easily remove to post them while teaching the standard then place them back into the binder when finished with the standard.
