The Roundhouse Aquarium is committed to providing ocean science education for all.


The Board of Directors for the Oceanographic Teaching Stations, Inc. (OTS) is proud of its long history of providing education equity for underserved children. Many of the young students who have attended our marine science classes are from disadvantaged or low-income families, or attend Title I schools. These marine science classes teach the children about the sea animals that live off our coast and the importance of protecting their environment from pollution. 

Since providing education equity for underserved children has historically been a priority for OTS, OTS hereby formally adopts a policy of providing educational equity for underserved children when providing free marine science classes at either the Roundhouse Aquarium or at schools. These OTS onsite and outreach classes provide access to underserved children and Title I schools that greatly benefit these children in their understanding of marine science.
