The study aimed to investigate the relationship between consciousness about environmental education (EE) concepts in senior secondary school chemistry curriculum and the attitude of Nigerian chemistry students toward the environment. The study utilized a descriptive survey design using simple random sampling and stratified proportionate sampling techniques. A sample of 400 senior secondary school science students from the 18 senior secondary schools participated in the study. Two structured questionnaires "Students Attitude to Environment Questionnaire" (SAEQ) and "Students Consciousness toward Environment Questionnaire" (SCEQ) were developed by the researcher. The validity coefficient of the SAEQ and SCEQ was 0.801 and 0.765, respectively. Three research questions and three null hypotheses guided the study. Data collected were analysis using mean standard deviation, one-way analysis of variance, and Pearson product moment correlation. The findings from the study revealed that the student environmental consciousness influenced their attitude toward the environment and that students' continuous exhibition of attitude toward the environment was rooted in their inadequate consciousness or knowledge of the causes and effects of environmental problems. As a result of this research, it is recommended that the Ministry of Education updates the curriculum of senior secondary school managing EE content.
