Science Department

The Science department’s main goal is to provide students with exposure to all types of science (both physical and life) so that they have a well rounded understanding of the world around them. They also aim to increase their proficiency in scientific reasoning and problem solving skills, which will be an asset to them the rest of their lives. The department encourages students to consider professions in the science realm as there is a lot of important and meaningful work in the field and there is a shortage of people pursuing these careers. The department is excited to be widening the availability of courses to include more ability levels and grade levels so that more students have the opportunity to learn.
