This OLogy activity shows kids that there are simple, but very helpful things they can do to protect the ocean -- even if they live nowhere near the water. The activity opens by introducing kids to Gabby, a future marine biologist who wants to study dolphins. Then it has a checklist of 14 ways kids can be ocean helpers that includes asking for tap water instead of bottled water and leaving plants and animals where they find them.

This video segment from the Science and Technology Chat series focuses on dolphin pregnancy, birth, and care of the young, and features Atlantic bottlenose dolphins living in captivity at the Mirage Resort Dolphin Habitat.

The dolphin is built to be sleek. Its body is made of almost entirely backbone (a gliding joint) which makes it very flexible under water. The ribs protect the inner organs of the dolphin and the tail beats from side to side, thrusting the animal forward.

The flippers of the dolphin help it swim through water. The ball and socket joint at the shoulder help the dolphin steer and roll while in the water, allowing it to actively swim and catch food while avoiding its predators.

The carnivorous dolphin uses its sharp teeth to grab and hold onto slippery prey. The skull, which protects the brain, is built to be sleek and allows the dolphin to move fast through water.

The dolphin has a large mouth to consume large prey. This animal has a flexible skeleton and flippers/long fingers to move quickly and gracefully through the ocean. The ribs of the dolphin protect the animal's internal organs, but are loosely attached to the spine so they can collapse during dives to the deep ocean.

Dolphins are mammals because they have lungs. Even though they live in the water, they must come to the surface to breathe air. They are one of the few mammals that don't have fur.

Meet the Marine BiOLogists is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they meet three kids and one scientist who dive deep when it comes to learning about the ocean: Gabriela, an 11-year-old from New York whose interest in marine biology began with a family trip she took to the West Indies when she was five. Gwyneth, an 11-year-old from California who likes observing the sea birds when she visits her father's beach house. Luke, a nine-year-old from Belfast, Ireland, who watches the seals play in the Atlantic Ocean each summer during his two-month holiday at Portrush, on Ireland's north coast. Melanie Stiassny, an ichthyologist at the museum, who answers kids questions, including "Does identifying fish make a difference?" and "How do you know when you've discovered a new species?"

This video resource from Jean-Michel Cousteau: Ocean Adventures explores the unique adaptations developed by the pink river dolphin in order to survive in the freshwater rivers of the Amazon.

NBC's Lester Holt looks at the physically demanding pre-season ritual of NFL training camp. Douglas Casa, head of the Korey Stringer Institute at the University of Connecticut, and athletic trainers from the Pittsburgh Steelers explain what NFL players must do to stay hydrated and replenish the essential nutrients needed to maintain good health during rigorous practices. "Science of NFL Football" is a 10-part video series funded by the National Science Foundation and produced in partnership with the National Football League.

This case study is based on the 1978 – 1988 Bottlenose dolphin die-offs along the Atlantic coast of the U.S. It demonstrates nature of science, as new information evolved theories change. New observations lead to more sophisticated inferences, as more observations are carefully recorded, better inferences can be made.
