White sharks are found mostly in cool waters close to the coast. White sharks are considered super swimmers, reaching speeds of over 56 km/h (35 mph) depths of 1,200 m (3,900 ft). They can live to be as old as 70 and don't produce offspring until they are about 33 years of age. White sharks can grow to be 6m (18ft) long with 300 razor sharp teeth arranged in seven rows. This coupled with the famous Jaws movies has given white sharks a bad rap.
The great white shark has no known natural predators other than, on very rare occasions, the killer whale. The great white shark is arguably the world's largest known predatory fish, and is one of the primary predators of marine mammals. It is also known to prey upon a variety of other marine animals, including fish and seabirds.
New research reveals that Atlantic white sharks, which were hunted indiscriminately for almost two decades following the release Jaws, have slowly been making a comeback. Listen to the program here.
NOAA Fisheries is responsible for the stewardship of the nation's ocean resources and their habitat. They provide vital services for the nation: productive and sustainable fisheries, safe sources of seafood, the recovery and conservation of protected resources, and healthy ecosystems—all backed by sound science and an ecosystem-based approach to management.
C1 Patterns. Children recognize that patterns in the natural and human designed world can be observed, used to describe phenomena, and used as evidence
C6 Structures and Functions. Students observe the shape and stability of structures of natural and designed objects are related to their function(s).
C1 Patterns. Students identify similarities and differences in order to sort and classify natural objects and designed products. They identify patterns related to time, including simple rates of change and cycles, and to use these patterns to make predictions.
C6 Structures and Functions. Students learn different materials have different substructures, which can sometimes be observed; and substructures have shapes and parts that serve functions.
C6 Structures and Functions. Students model complex and microscopic structures and systems and visualize how their function depends on the shapes, composition, and relationships among its parts. They analyze many complex natural and designed structures and systems to determine how they function. They design structures to serve particular functions by taking into account properties of different materials, and how materials can be shaped and used.
C6 Structures and Functions. Students investigate systems by examining the properties of different materials, the structures of different components, and their interconnections to reveal the system’s function and/or solve a problem. They infer the functions and properties of natural and designed objects and systems from their overall structure, the way their components are shaped and used, and the molecular substructures of their various materials.
ESS2.C The Roles of Water in Earth's Processes. Water is found in many types of places and in different forms on Earth
LS1.A Structure and Function. All organisms have external parts that they use to perform daily functions.
LS1.B Growth and Development of Organisms. Parents and offspring often engage in behaviors that help the offspring survive.
ESS2.C The Roles of Water in Earth's Processes. Most of Earth’s water is in the ocean and much of the Earth’s fresh water is in glaciers or underground.
LS1.A Structure and Function. Organisms have both internal and external macroscopic structures that allow for growth, survival, behavior, and reproduction.
LS1.B Growth and Development of Organisms. Reproduction is essential to every kind of organism. Organisms have unique and diverse life cycles.
PS4.A Wave Properties. Waves are regular patterns of motion, which can be made in water by disturbing the surface. Waves of the same type can differ in amplitude and wavelength. Waves can make objects move.
ESS2.C The Roles of Water in Earth's Processes. Water cycles among land, ocean, and atmosphere, and is propelled by sunlight and gravity. Density variations of sea water drive interconnected ocean currents. Water movement causes weathering and erosion, changing landscape features.
LS1.B Growth and Development of Organisms. Animals engage in behaviors that increase the odds of reproduction. An organism’s growth is affected by both genetic and environmental factors.
LS4.C Adaptation. Species can change over time in response to changes in environmental conditions through adaptation by natural selection acting over generations. Traits that support successful survival and reproduction in the new environment become more common.
PS4.A Wave Properties. A simple wave model has a repeating pattern with a specific wavelength, frequency, and amplitude, and mechanical waves need a medium through which they are transmitted. This model can explain many phenomena including sound and light. Waves can transmit energy
ESS2.C The Roles of Water in Earth's Processes. The planet’s dynamics are greatly influenced by water’s unique chemical and physical properties.
LS4.C Adaptation. Evolution results primarily from genetic variation of individuals in a species, competition for resources, and proliferation of organisms better able to survive and reproduce. Adaptation means that the distribution of traits in a population, as well as species expansion, emergence or extinction, can change when conditions change.
PS4.A Wave Properties. The wavelength and frequency of a wave are related to one another by the speed of the wave, which depends on the type of wave and the medium through which it is passing. Waves can be used to transmit information and energy.
