Global advocacy on environmental sustainability strongly sheds light to illumine the ever pressing issue on exponential environmental degradation. In line with this, educating pro-environmental 21^st century learners with the vision of a sustainable future indeed serves as a crucial yet significant step towards the goal. Hence, the purpose of this study was to identify the level of awareness of the grade 8 Filipino students in urban and rural school contexts based on the seven environmental themes. It also aimed to determine its implications in teaching science. This descriptive quantitative study used purposive sampling. An Environmental Awareness Questionnaire (EAQ) was deployed using a sample of 150 students from two urban private schools and 150 students from one rural public school. From the conducted research, the analysis revealed that the students from urban schools have high level of environmental awareness while the students rural schools expressed very high level of using descriptive statistics. However, no significant difference was identified between the students' environmental awareness using z-test statistical analysis, which was then further supported by the values of standard deviation from two sample groups. Students situated in urban area manifested environmental awareness are greatly influenced by the fact that they are directly benefitting from the environment they live in.
