2
|
The student will apply process skills to develop an understanding of physical science including: properties, changes of properties of matter, motion and forces, and transfer of energy.
|
|
|
|
|
2.1
|
The student will observe, compare, and classify properties of matter.
|
|
|
|
|
2.1.1
|
The student compares and classifies the states of matter; solids, liquids, gases, and plasma.
|
|
|
|
|
2.1.2
|
The student compares and contrasts the classes of matter; elements, compounds, and mixtures.
|
|
|
|
|
2.1.3
|
The student identifies and communicates properties of matter including but not limited to, boiling point, solubility, and density.
|
|
|
|
|
2.2
|
The student will observe, measure, infer, and classify changes in properties of matter.
|
|
|
|
|
2.2.1
|
The student understands the relationship of atoms to elements and elements to compounds.
|
|
|
|
|
2.2.2
|
The student measures and graphs the effects of temperature on matter.
|
|
|
|
|
2.3
|
The student will investigate motion and forces.
|
|
|
|
|
2.3.1
|
The student identifies the forces that act on an object (e.g., gravity and friction).
|
|
|
|
|
2.3.2
|
The student describes, measure, and represents data on a graph showing the motion of an object (position, direction of motion, speed).
|
|
|
|
|
2.3.3
|
The student recognizes and describes examples of Newton's Laws of Motion.
|
|
|
|
|
2.3.4
|
The student investigates and explains how simple machines multiply force at the expense of distance.
|
|
|
|
|
2.4
|
The student will understand and demonstrate the transfer of energy.
|
|
|
|
|
2.4.1
|
The student understands the differences between potential and kinetic energy.
|
|
|
|
|
2.4.2
|
The student understands that when work is done energy transforms from one form to another, including mechanical, heat, light, sound, electrical, chemical, and nuclear energy, yet is conserved.
|
|
|
|
|
2.4.3
|
The student observes and communicates how light (electromagnetic) energy interacts with matter: transmitted, reflected, refracted, and absorbed.
|
|
|
|
|
2.4.4
|
The student understands that heat energy can be transferred from hot to cold by radiation, convection, and conduction.
