Read More about Our world is such an exciting adventure in learning. Each day our students at LBJ are introduced to new stimulating fields of discovery. The latest topic in the 4th grade classrooms is how our planet Earth is changing. After studying chapters in science book our children were allowed to create their own dioramas illustrating the impact of pollution on ozone layer, global warming and temperature change. They worked very hard being unique and wrote excellent papers on what knowledge they had acquired in their many hours of devoted research. Hats off LBJ COWBOYS!
