The horseshoe crab is a remarkable prehistoric animal and a modern medical marvel. Middle school students in South Carolina investigate horseshoe crabs, their life cycle, habitats, and the threats that affect them. One of nature’s puzzle pieces, they fit into place as an important partner with humans.

Animal researchers travel to Easter Island, one of the most remote inhabited islands on Earth, where a mystery illness is plaguing horses. A chance encounter by a veterinary pathologist reveals a disturbing fact: an invasive, non-native plant introduced to prevent soil erosion is poisoning the horses. Segment of video from Wild Chronicles Series.
Horseshoe crabs are "living fossils" more closely related to spiders and scorpions than they are to crabs. They get their name from the smooth, hard shell (exoskeleton) that is shaped like a horseshoe. Part of "The Remarkable Horseshoe Crab" series.
The ancestors of the horseshoe crab have roamed Earth for over 450 million years. They may look creepy, but they are not dangerous. Their numbers have been declining, and scientists have been trying to help preserve them. Part of "The Remarkable Horseshoe Crab" series.
During horseshoe crab spawning season, volunteers are dispatched along the Mid-Atlantic coast to help scientists track their populations. Learn how citizen scientists track the data to help preserve the horseshoe crab. Part of "The Remarkable Horseshoe Crab" series.
One of the oldest, most successful arthropods on Earth, horseshoe crabs have existed for over 350 million years. But in recent years their populations, have crashed by 75% from overfishing, resulting in moratoriums on catching them. Few of us know that most human lives depend on the valuable, shockingly blue blood of these "living fossils." Even more surprising, a tiny shore bird, the red knot, is so dependent on them that the crabs' population crash may make these long-distance flyers extinct. This mystery of mutual dependencies emerges from filmmakers and scientists revealing a disturbing ecology story ranging from the Arctic regions to the southern tip of the Americas.
New research led by scientists at the University of California, Berkeley, suggests that the shape of some animals' pupils could reveal whether one is hunter or hunted. An analysis of 214 species of land animals shows that a creature's ecological niche is a strong predictor of pupil shape. Species with pupils that are vertical slits are more likely to be ambush predators that are active both day and night. In contrast, those with horizontally elongated pupils are extremely likely to be plant-eating prey species with eyes on the sides of their heads.
How do horseshoe crabs keep humans healthy? They have blue, copper-based blood, which quickly clots in the presence of bacterial toxins. Medical researchers use it to test intravenous drugs, vaccines, and medical devices, ensuring that they are free of bacterial contamination. Part of "The Remarkable Horseshoe Crab" series.
Inside a cylinder that is about the size of a roll of paper towels lives a circuit board filled with sensors. It's called a dropsonde, or “sonde” for short. As the sonde falls through the air after being dropped for an airplane, its sensors gather data about the atmosphere. Dropsondes have a huge impact on understanding hurricanes and the ability to predict hurricanes. Part of the National Science Foundation Series “Science Nation.”
Meet an education specialist from the Delaware National Estuarine Research Reserve. She says becoming a scientist is all about being curious, and she helps researchers count the horseshoe crabs on the Atlantic coast. Part of "The Remarkable Horseshoe Crab" series.
Features Emily, the six-year-old host, who takes care of horses, rides on a tractor, learns about chickens, becomes a cowgirl, and makes goat cheese. Using a natural, unscripted format, Emily investigates the world through her own candid comments and questions, engaging everyone she meets. Teaches young learners basic concepts about the world around them in a manner that is positive and nonthreatening.
The king wants to buy two red horses and a humpbacked horse from a boy. From the Kool Books series narrated by Hector Bonilla.
This video discusses the principle of force and the application of Newton's three laws of motion. Through the use of real-world examples, students will witness the effect of friction on force. Other topics covered include inertia, weight, mass, gravity, and the law of universal gravitation.
Some miniature horses have experienced an unintended consequence of over breeding for smallness: dwarfism. This affects their physical appearance as well as quality of life. Shelters have been established to take of these horses.
When Genoveva opens her magic book, the screen is filled with feathers, beaks, horns, legs, wings, and snouts. Genoveva's magic book transports her to various habitats where she learns about the animals that live there. In this episode, Genoveva watches as horses run through open and green meadows.
Presents information on horses in magazine-type format. The first segment features children preparing for a vaulting competition (controlled gymnastics on the back of a horse). In the second segment four teens participate in a jumping competition at a horse show. Segment three shows a beginning rider visiting a tack shop to purchase riding apparel and equipment. In the last segment a professional horse trainer gives practical advice on buying a horse.
A riding instructor and barn manager discusses her career in equestrian therapy. She works at a nonprofit that provides services for people with developmental disabilities. Part of the "Career Connections" series.
Wilbur the puppet introduces preschool children to familiar farm animals and the sounds they make. Encourages viewers to imitate the sounds of pigs, horses, roosters, sheep, dogs, ducks, rabbits, chicks and hens, donkeys, cats, goats, geese, and cows. Shows both adult and baby animals. No factual information given.
A ball flying through the air, a deer walking in the woods, and a flowing river - these are all examples of moving objects. Students explore the characteristics of things in motion, and special attention is given to the forces that initiate and change their movement. Concepts and terminology discussed include: motion, push, pull, force, direction, and speed.
What are explorers? What do they do? What skills do they need? Is exploring done today? How can students be explorers? Following a summary of the 18-month Lewis and Clark expedition, elementary students learn about Will Steger, contemporary arctic explorer. Emphasizes the importance of keeping a journal to record what is seen and heard. Students explore nearby woods and share their discoveries.
