On a WorldStrides science action adventure program, students experience science like they never have before, as they visit some of the most educational and exciting destinations Costa Rica has to offer. WorldStrides educational activities support, at minimum, various Next Generation Science standards for students at the 6-12 level. Most importantly, our hands-on approach focuses on developing students understanding of inquiry-based science through investigation and experimentation. Please note that standards selected for grades 9-12 also incorporate standards selected for grade 6-8 in addition to application of greater depth and breadth of standards appropriate to a high school science curriculum. Program content for grades 6-8 may also draw from standards for grades 9-12, with appropriate adjustment for learning objectives and level.
