Four-Year Sequences in Science

Core courses in Science are: Ecology & Environmental Science, Biology, Chemistry, and Physics. All ARHS students begin their studies with Ecology & Environmental Science or Ecology & Environmental Science / Honors. After that year, students have a variety of options from which to choose. Students can take a college prep course one year and an honors course the next (or vice versa). Listed below are two possible sequences that allow students to take all four of the core courses (Note: Remember to consider mathematics prerequisites when planning a sequence):

Student #1: Standard Pathway

9^th Grade	10^th Grade (MCAS)	11^th Grade	12^th Grade
Ecology & Env. Sci. or Ecology & Env. Sci. / Honors	Biology or Biology/Honors	ChemCom or Chemistry or Chemistry/Honors or Electives	Physics or Physics/Honors or Physics/AP or Electives

Student #2: Alternate Pathway

9^th Grade	10^th Grade (MCAS)	11^th Grade	12^th Grade
Ecology & Env. Sci. or Ecology & Env. Sci. / Honors	Chemistry/Honors*	Biology or Biology/Honors or Biology/AP (3-term)* or Electives	Physics/Honors or Physics/AP or Electives

*Chemistry/Honors is open to tenth graders who plan to take AP biology (3-term) in eleventh grade.
