Change and constancy occur in systems as patterns and can be observed, measured, and modeled.

These patterns help to make predictions that can be scientifically tested. The student, for at least 40% of instructional time, conducts laboratory and field investigations using safe, environmentally appropriate, and ethical practices.

Aquatic Science, Beginning with School Year 2010-2011 (One Credit). Students shall be awarded one credit for successful completion of this course.

Required prerequisite: one unit of high school Biology.

Scientific methods of investigation can be experimental, descriptive, or comparative.

Turning heat into motion via heating coils and hydrogels could provide a source of locomotion without a bulky, inflexible motor.The student is expected to: (A) demonstrate basic principles of fluid dynamics, including hydrostatic pressure, density, salinity, and buoyancy; (B) identify interrelationships between ocean currents, climates, and geologic features; and (C) describe and explain fluid dynamics in an upwelling and lake turnover. The student knows the types and components of aquatic ecosystems.The student is expected to: (A) differentiate among freshwater, brackish, and saltwater ecosystems; (B) identify the major properties and components of different marine and freshwater life zones; and (C) identify biological, chemical, geological, and physical components of an aquatic life zone as they relate to the organisms in it. The student knows environmental adaptations of aquatic organisms.The burst of vapor created when the hydrogel first hits the hot pan deforms the ball, which, because of its elastic nature, is able to store the energy.The ball bends first inwards and then springs back, providing the kick necessary to propel the ball back into the air.
