Data presented in this paper were gathered in 2016 as part of a research project on water-related infectious disease exposure and WASH in Rumuruti, Laikipia County, Kenya. Based on a rapid screening of teaching materials used in the study area, we identified science education as the single source of information related to WASH and disease risks in primary schools. We therefore collected the science text books in use at the time of this study. Eight primary school standard science books used from class 1 through class 8 covering the age range from 6 to 13 years were obtained and analyzed.
