Teaching Interdisciplinary & Experiential Sciences

TIDES™ is a multi-year, immersive marine science program for 7th -12th graders that combines rigorous interdisciplinary science curriculum, hands-on learning, and confidence-building scuba training to unlock students’ natural curiosity and passion for the ocean.

As part of TIDES, students receive real-life experiences in marine research and scientific diving. These place-based learning opportunities provide a window into the careers of marine scientists, technicians, and field researchers. Students will practice critical thinking and data analysis, which together introduce them to the process of asking questions, defining problems, and carrying out investigations in real-world settings.

In the classroom, or online, students will begin by investigating the seven principles of Ocean Literacy. These fundamental concepts will provide the backbone to understanding how we are connected to the ocean and why it’s so important. Students are then free to pick their own path of ocean discovery, from fish and coral identification to measuring sharks and sea turtles with lasers, the opportunities are limited only by our imagination. TIDES' place-based learning experiences are designed to inspire and challenge even the most ambitious young minds and increase engagement in and access to many important STEM related fields.

How It Works


As students progress through the program, they will take courses in both marine science and scuba diving, which together will be utilized as they move from the classroom and pool into the field and become citizen scientists.


Academics- The academic work is completed online via a teacher curated and facilitated learning community where students have access to expert dive instruction via Scuba Schools International and standards-based marine science instruction through Ocean First Education.


In-Water Instruction- Students will complete the Open Water Scuba Diver certification, which will be the foundation for their research projects, as well as a lifetime of exploration and discovery.

Choose Your Adventure- With six programs to choose from, the flexible format truly gives students the freedom to explore the aspects and questions that inspire them the most.


The science curriculum is aligned to Next Generation Science Standards (NGSS) and provides a safe and secure online learning environment. Our STEM (Science, Technology, Engineering & Math) focus increases engagement in, and access to, these important fields, which we hope will help combat the disproportionate representation of women in many scientific fields. Though studies have shown women are discouraged from, or become less interested in, entering the STEM fields at a young age, roughly half of all TIDES students are female.

In addition to the many benefits associated with experiential, place-based learning, students also:

  • Build confidence and self-esteem.
  • Help unlock students’ natural curiosities for science and the marine environment.
  • Practice critical thinking and data analysis.
  • Are introduced to the process of asking questions, defining problems, and carrying out investigations in real-world settings.
