Abstract
Ever wonder how marine mammals communicate with each other in an expansive dark ocean? Most of their communication is through the sense of sound, and their vocalizations can travel great distances in the ocean. However, human-generated noise pollution can interfere with their communication. This student activity provides information about dolphin and whale species and examples of their vocalizations. It is engaging for all students, including those with visual impairment, as the lesson is auditory. We anticipate that the provided information will spark further interest in marine mammals and help develop a better awareness of interactions between organisms and their environment. The activity conforms to Next Generation Science Standards, National Science Standards, and includes Ocean Literacy Principles.
Highlights
Student opportunities for hands-on, experiential activities can be rare for a variety of reasons, including budget cuts, liability, and curricula focused on standardized tests

Summary
Student opportunities for hands-on, experiential activities can be rare for a variety of reasons, including budget cuts, liability, and curricula focused on standardized tests. These changes might require more energy on the part of the sound producer, affecting their physiology in addition to the more obvious impacts on communication and echolocation For this activity, marine mammal sounds have been compiled from colleagues and from the Macauley Library at the Cornell Lab of Ornithology and the Watkins Marine Mammal Sound Archive at the Woods Hole Oceanographic Institution (http:// www.whoi.edu/watkinssounds/; Sayigh et al 2016). The PowerPoint can be supplemented with plastic models of cetacean species if available, which provides a hands-on component that is useful for both sighted and visually impaired students by incorporating the sense of feel with the sense of sound, enhancing multisensory learning. What is the largest animal to have ever lived on Earth? What does it eat? How does the relative size of its food compare to the size of its body?
