Science
Unity High School expects to offer standard high school science courses, following this sequence: Astronomy/Cosmology; Biology; Chemistry and Physics. The science curriculum is built off of video instruction available through Khan Academy. The teacher will review the following subject matter and condense it into the 18-week semester schedule in each instance. Most classes during the entire four-year sequence will involve viewing a short video, instruction provided by the in-classroom educator, discussion, and some hands-on project work, either individually or in groups.
