Tennessee Standard 2.2a - How an object functions is related to its form.

 

Specialized structures perform specific functions. Symmetry (or the lack of it) may determine properties of many objects, from molecules and crystals to organisms and designed structures. All objects in the universe are affected by the gravitational forces. Equal volumes of different substances usually have different weights. There are different forms of energy such as heat, mechanical, chemical, electrical, nuclear, and light. The flow of energy has an impact of geological, biological and environmental conditions.

THEME: 2.4 INTERACTIONS - At all levels of living and non-living systems, matter and energy act and react to determine the nature of our environment.

Tennessee Standard 2.4a - Interactions occur on scales ranging from elementary particles to galaxies.

 

Every object exerts gravitational force on every other object. Atoms and molecules are perpetually in motion. There are groups of elements that have similar properties. Gravitational force depends on how much mass the objects have and on how far apart they are. Human beings cope with changes in their environment through the interactions among the senses, nerves, and brain. Viruses, bacteria, fungi, and parasites may alter the function of an organism. Scientists are still working out the details of what the basic kinds of matter are and how they combine.

Tennessee Standard 2.4b - Interactions of matter and energy shape our world.

 

The cycling of water in and out of the atmosphere plays an important role in determining climatic patterns. Heat can be transferred either through materials by the collisions of atoms or across space by radiation. Electric currents and magnets can exert force on each other. In any particular environment, the growth and survival of organisms depend on the physical conditions. The relationships between two organisms may be competitive or mutually beneficial.

THEME: 2.5 CHANGE - Interactions within and among systems may result in changes in the properties, position, movement, form, or function of systems.

Tennessee Standard 2.5b - Cycles of change can be extended in scales of time, space, and material.

 

Some changes in the earth’s surface are abrupt while other changes happen very slowly. In the absence of retarding forces, such as friction, an object will keep its direction of motion and its speed. Sedimentary rocks provide evidence for the long history of the earth. The motion of an object is always judged with respect to some other object.

THEME: 2.6 CONSERVATION - In any natural process the form may change but nothing is lost.

Tennessee Standard 2.6a - Although there can be transformations of matter and energy in changes, the sum of matter and energy is conserved.

 

No matter how atoms are rearranged, their total mass stays the same. As in all material systems, the total amount of matter remains constant, even though its form and location change. Energy is neither created nor destroyed but only changes form.

In order for a question to be scientifically feasible it must be experimentally testable and answerable. Working hypotheses are formulated to guide the process of research. When events of the past are presented to explain present phenomena, validity is contingent upon similarity of conditions.
