Do you ever feel like there are too many cool STEM fields to choose from? Ocean Science might be for you – a field that involves geology, biology, chemistry and physics! 

Dive into this multidisciplinary field with ocean scientist, Mikaela! Create a model of the great conveyor belt (if you don’t know what that is, you definitely need to check out this session!),  do experiments to explore how ocean acidity and temperature affect coral reefs and other marine life, and so much more!
