Studying and exploring spaceEdwin Powell Hubble (1889-1953) was an American astronomer who, in 1923, showed that the universe is expanding. He used photographs to prove that there are galaxies beyond our own. Prior to this, scientists believed that our galaxy was the entire universe. In 1990, the Hubble Space Telescope (clearly named in honor of the great 20th century astronomer) was launched by NASA and has provided some of the most spectacular images of the universe ever seen.

Nonrenewable resources are resources that, once consumed, cannot be replaced. Because oil, natural gas, and coal are the products of plants and organisms, they are known as fossil fuels. Fossil fuels are ultimately a limited resource, it is important to develop and use renewable energy resources.

Even though solid rock like granite or marble has no pores, it often has a series of cracks and possibly faults. Water accumulates in the cracks in solid bedrock and, at times, is a source of water. A layer of rock material that can store water and allow the movement of water through the ground is called an aquifer.

Systems and System Models
SCI.CC4.m. Students understand systems may interact with other systems: they may have sub-systems and be a part of larger complex systems. They use models to represent systems and their interactions—such as inputs, processes, and outputs—and energy, matter, and information flows within systems. They also learn that models are limited in that they only represent certain aspects of the system under study.

Energy and Matter
SCI.CC5.m. Students understand matter is conserved because atoms are conserved in physical and chemical processes. They also understand that within a natural or designed system the transfer of energy drives the motion and cycling of matter.

Properties of matter and EnergyWhat is matter? Matter is anything that takes up space and has mass. Kinetic energy is energy that is happening now; it is energy in motion. Potential energy is energy that is waiting to happen; it is stored energy. How does heat get transferred: By conduction, by convection and by radiation.

They understand changes in one part of a system might cause large changes in another part, systems in dynamic equilibrium are stable due to a balance of feedback mechanisms, and stability might be disturbed by either sudden events or gradual changes that accumulate over time.

Sound Waves: an invisible transfer of sound energy as it travels away from the energy source. Wavelength: the distance between a point on one sound wave and a similar point on another sound wave. Frequency: The number of vibrations in a period of time is called the frequency of a vibration. Volume: The loudness or quietness of a sound is its volume.
