Center for Environmental and Natural Sciences


The Center for Environmental and Natural Sciences (CENS) specialty program at Freedom High School offers a rigorous four-year program of studies designed to include strong laboratory and field investigation components. The program emphasizes interactive science research and projects that make use of the on-site CENS lab, greenhouse, aquarium, diverse habitats, and wet pond. 

The mission of CENS is to promote environmental citizenship and a sustainable community through service and challenging hands-on collaborative learning experiences that promote innovative thinking, problem solving, and leadership within our school and community. Freedom High School aims to create a sustainable society of students that embodies respect and care for the community of life and ecological integrity.

Students will complete service hours and a sequence of required CENS science courses.  Students will select one of the three available pathways within CENS: Environmental Science, Environmental Engineering, and Law and Public Safety.  Within each pathway, students can earn a CENS Certificate, CENS Merit or a CENS Medal.  Additional information on the pathways can be found on the school website.
