Know that an element is a pure substance represented by a chemical symbol and that a compound is a pure substance represented by a chemical formula;
Recognize that a limited number of the many known elements comprise the largest portion of solid Earth, living matter, oceans, and the atmosphere; and
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.
Compare metals, nonmetals, and metalloids using physical properties such as luster, conductivity, or malleability;
Calculate density to identify an unknown substance; and
Test the physical properties of minerals, including hardness, color, luster, and streak.
Research and discuss the advantages and disadvantages of using coal, oil, natural gas, nuclear power, biomass, wind, hydropower, geothermal, and solar resources.
Investigate methods of thermal energy transfer, including conduction, convection, and radiation;
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.
Compare and contrast potential and kinetic energy;
Identify and describe the changes in position, direction, and speed of an object when acted upon by unbalanced forces;
Measure and graph changes in motion; and
Calculate average speed using distance and time measurements;
Investigate how inclined planes can be used to change the amount of force to move an object
