Science Department

The Paint Branch High School Science Department is committed to providing science instruction for all students. Our program addresses what students should know and be able to do in science, preparing them for further scientific study, as well as for their role as young citizens, in a world where science literacy is a basic need.

Typical Science Experience

If the 8th Grade Science Grade is an A or B:  

  • Students can enroll in: Honors Physics 9 * OR Honors Biology. Students enrolling in Honors Physics 9 ALSO need to have completed Algebra I by the end of 8th Grade with a final exam grade of an A or B AND concurrent enrollment in at least Honors Geometry.

If the 8th Grade Science Grade is a C or below:  

  • Students can enroll in: Honors Matter & Energy
    As a Science Signature school, we believe all students need to be challenged academically. Thus, students not enrolled in Honors Physics 9 or Honors Biology will take Honors Matter and Energy.

Academy of Health Professions

In the double period Medical Careers class first semester students learn patient care, anatomy and physiology, pharmacology, diseases and disorders, and infection control and they earn CPR and First Aid certification from a registered nurse and certified teacher. Second semester they intern four days a week for 90 minutes each day at Holy Cross Hospital, where they rotate through at least ten departments for two weeks each. The departments include emergency, pediatrics, cardiology, radiology, physical therapy, and post-natal care.
