    Welcome to the Science Department

    The science program at IRHS provides students with many opportunities to develop skills that can be utilized in any area of future endeavour. A student participating in IRHS Science also has the opportunity to learn a tremendous amount about the physical and biological sciences.


    Introductory Biology

    Introductory Biology is a biology class for freshmen. We investigate a wide range of topics, from molecular biology to ecology, and lots in between. The class is designed to help students develop academic and personal skills, but is also geared towards promoting interest in the sciences, which statistically drops off in the high school years.
