Science
Radnor High School's Science program provides students with depth and breadth of scientific knowledge and skills through a well-defined sequence of studies. The sequence of Science classes is, in order, Biology, Chemistry and Physics. Each discipline has three levels of instruction and each level has different expectations and requirements. Science electives, Bioethics and Genetics, are offered to juniors and seniors
Overview
Levels
Honors
An Honors-level class has the highest emphasis on rigor and mastery of the sciences. Students are highly motivated and hard-working learners capable of independent study at a rigorous pace. The average honors student will have 4-6 hours/week of out-of-class work including homework and written laboratory reports. The honors level assignments will engage students with higher critical thinking skills with the greatest conceptual understanding. These students are expected to study and read beyond what is done in the classroom. Higher critical thinking skills such as evaluation, synthesis, and analysis of data and concepts are emphasized. Students must be in either the advanced or more likely the honors level mathematics classes for success at this level.
Advanced
An Advanced-level class has a moderate pacing and workload. These advanced level classes are for students motivated in science and capable of some independent work. The average advanced student will have 3-4 hours/week of out-of-class work including homework and written laboratory reports. The assignments are more concrete and teacher-lead. Students are challenged to improve their critical thinking skills such as analysis, comparison and contrast concepts and also the ability to collect, organize, and interpret data. Students must be at the advanced math level to achieve maximum success.
College Preparatory
A College Preparatory-level class is paced appropriately for the students and emphasizes the fundamental concepts, vocabulary, and skills of each discipline. Hands-on activities and laboratory investigations are important in developing student understanding. The average academic student will have 2-3 hours/week of out-of-class work that includes homework and lab work that will reinforce concepts learned in the classroom. Assignments and tests emphasize comprehension, application, and analysis. They also stress more concrete concepts with greater hands-on applications. Students starting at this level will have the highest degree of teacher guidance, but will work toward greater self-reliance by the end of the course
