Science Department

The Science Department at ACS aims to raise scientifically literate life-long learning students who appreciate science and view it as a process-driven, dynamic and on-going pursuit that attempts to explain the natural world, regardless of their future aspirations. It also aims to promote among students the understanding of the impact of science on society and of the responsibility and ethical considerations involved in scientific pursuits. By showing students that science is a discipline worthy of passion, we share our appreciation of the beauty of science.

Science Courses

To facilitate and activate the learning process, all science courses combine class discussions, group work, cooperative learning sessions, problem-solving sessions, video projections, class activities, varied laboratory sessions, demonstrations, computer simulations and activities, web quests, presentations and others. Research skills are reinforced throughout the curriculum by projects, by planning labs, and/or by open-ended lab sessions. Assessment is frequent and is generally made through teacher’s observations, student answers and participation in class discussions, tests, quizzes, lab work, lab reports, assignments/homework, presentations, projects, and cooperative learning work using rubrics and other methods of evaluation. All courses have a course guide that includes a course description, outline, the learner outcomes, assessment policies, grading distributions, rubrics and any other course expectation and info. The lab work is also explained in the course guides.
