Science and Children and Science Scope are peer-reviewed science practitioner journals that publish articles for science educators who teach children ages 5-10 years and 10-13 years, respectively. As such these articles are a reflection of the science concepts that are being communicated to science educators. This comprehensive literature review was completed to determine the extent to which the articles included in these journals from 1990-2014 focused on biology concepts, included other topics and science subjects, and encouraged inquiry-based learning. The results indicate that out of the 2,701 total articles 557 (21%) focused on biology. The biology concept covered most often by both journals was animals. The biology concepts covered least often were fungi, photosynthesis, respiration, and viruses. The findings are taken into consideration and the educational implications for the journals and educators are discussed.
