Know that scientific theories are based on natural and physical phenomena and are capable of being tested by multiple independent researchers. The functions and properties of natural and designed objects and systems can be inferred from their overall structure, the way their components are shaped and used, and the molecular substructures of its various materials. These properties include water's exceptional capacity to absorb, store, and release large amounts of energy, transmit sunlight, expand upon freezing, dissolve and transport materials, and lower the viscosities and melting points of rocks.

The abundance of liquid water on Earth's surface and its unique combination of physical and chemical properties are central to the planet's dynamics. Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data (e.g., number of trials, cost, risk, time), and refine the design accordingly.Īlignment agreement: Thanks for your feedback! This activity focuses on the following Three Dimensional Learning aspects of NGSS: Plan and conduct an investigation of the properties of water and its effects on Earth materials and surface processes.Ĭlick to view other curriculum aligned to this Performance Expectation Submersibles enable the exploration of depths much greater than can be reached via satellite and shipboard technologies these creative submersible and remotely operated vehicle (ROV) inventions are necessary for researchers to explore very deep ocean communities and discover new species. Scuba divers use special equipment such as weighting systems, diving suits and buoyancy compensators to control their buoyancy. Most boney fish have a swim bladder that enables them to control their buoyancy, or height in the water column, without swimming. The concepts of Pascal's law, Archimedes' principle, the ideal gas law and the density-buoyancy relationship are important in science, engineering and technology applications such as fish physiology, scuba diving and various submersibles.
