PHYSICAL SCIENCE

This is a quick summary of some of the subjects we will be covering this year:

MATTER AND ENERGY

SECTION 1 - DIFFERENCE BETWEEN ELEMENTS AND COMPOUNDS
    (A)  know that an element is a pure substance represented by chemical symbols;
    (B)  recognize that a limited number of the many known elements comprise the     largest portion of solid Earth, living matter, oceans, and the atmosphere;
    (C)  differentiate between elements and compounds on the most basic level; and
    (D)  identify the formation of a new substance by using the evidence of a     possible chemical change such as production of a gas, change in         temperature, production of a precipitate, or color change.

SECTION 2: PHYSICAL PROPERTIES CLASSIFICATION
(A)  compare metals, nonmetals, and metalloids using physical properties such as luster, conductivity, or malleability;
(B)  calculate density to identify an unknown substance; and
 test the physical properties of minerals, including hardness, color, luster, and streak.

SECTION 3: RENEWAL VS. NON-RENEWABLE RESOURCES
(A)  research and debate the advantages and disadvantages of using coal, oil, natural gas, nuclear power, biomass, wind, hydropower, geothermal, and solar resources; and
 design a logical plan to manage energy resources in the home, school, or community.

FORCE, MOTION AND ENERGY

SECTION 1: POTENTIAL AND KINETIC ENERGY
(A)  compare and contrast potential and kinetic energy;
(B)  identify and describe the changes in position, direction, and speed of an object when acted upon by unbalanced forces;
(C)  calculate average speed using distance and time measurements;
(D)  measure and graph changes in motion; and
 investigate how inclined planes and pulleys can be used to change the amount of force to move an object.

SECTION 2: LAW OF CONSERVATION OF ENERGY
(A)  investigate methods of thermal energy transfer, including conduction, convection, and radiation;
(B)  verify through investigations that thermal energy moves in a predictable pattern from warmer to cooler until all the substances attain the same temperature such as an ice cube melting; and
 demonstrate energy transformations such as energy in a flashlight battery changes from chemical energy to electrical energy to light energy.
