Diversity of Nature (DoN) is a cost-free BIPOC-focused and BIPOC-led educational initiative at Dalhousie University aimed at engaging, empowering and inspiring under-represented secondary high school students to pursue marine science and ecology. DoN offers a week-long immersive ecological field expedition, as well as a series of in-class science workshops to BIPOC secondary school students across Nova Scotia. Led by BIPOC graduate students in biology and oceanography, DoN aims to increase BIPOC representation within STEM by offering our program free of cost, letting students see themselves in leadership positions, and fostering long-term mentorships with successful BIPOC graduate students. Our graduate student teachers also benefit by taking on leadership positions and transmitting their knowledge of marine science and ecology to the next generation of scientists.
