    Description
    Eighth grade Science is a guided inquiry-based study of physics and chemistry. Students will analyze the properties of changes in matter, forms of energy, and interactions of forces. Students will inquire about how forces affect the position and motion of an object by exploring Newton's Laws of motion and how machines affect the work done. Students will investigate various forms of energy as well as exploring the properties of matter, atomic theory, development of the periodic table, conservation of matter, and kinetic theory. The guided exploration of the scientific and engineering practices through hands-on learning is embedded in all units of study.

    Note: This curriculum was written prior to the 2014-2015 school year. It is scheduled to be rewritten following the Rockwood Curriculum Schedule.

Unit Description
Details
8PS01Forces and Interactions
Students will engage in the science and engineering practices to understand ideas related to why some objects will keep moving, why objects fall to the ground and why some materials are attracted to each other while others are not.  Students will be able to apply Newton’s Laws of Motion to relate forces and explain the motion of objects.  Students will apply ideas about gravitational, electrical, and magnetic forces to explain a variety of phenomena. Students will develop ideas that objects can exert forces on each other even though the objects are not in contact, through fields. Students should apply an engineering practice and concept to solve a problem caused when objects collide.

8PS02Energy
Students will explore four sub-core ideas: Definitions of Energy, Conservation of Energy and Energy Transfer, the Relationship between Energy and Forces, and Energy in Chemical Process and Everyday Life. Students will develop their understanding of important qualitative ideas about energy, including that the interactions of objects can be explained and predicted using the concept of transfer of energy from one object or system of objects to another and that that the total change of energy in any system is always equal to the total energy transferred into or out of the system. Students understand that moving objects have kinetic energy and that objects may also contain stored (potential) energy, depending on their relative positions. Students will also come to know the difference between energy and temperature and begin to develop an understanding of the relationship between force and energy. Students are also able to apply an understanding of design to the process of energy transfer. These performance expectations expect students to demonstrate proficiency in developing and using models, planning investigations, analyzing and interpreting data, designing solutions, and engaging in argument from evidence, and to use these practices to demonstrate understanding of the core ideas in PS3.

8PS03Waves and Electromagnetic Radiation
Students will gain a better understanding of Wave Properties, Electromagnetic Radiation, and Information Technologies and Instrumentation. Students are able to describe and predict characteristic properties and behaviors of waves when waves interact with matter. Students can apply an understanding of waves as a means to send digital information. These performance expectations focus on students demonstrating proficiency in developing and using models, using mathematical thinking, and obtaining, evaluating and communicating information and using these practices to demonstrate understanding of the core ideas.

8PS04Structure and Properties of Matter
Students will be able to apply an understanding that pure substances have characteristic properties and are made from a single type of atom or molecule. They will be able to provide molecular-level accounts to explain states of matters and changes between states. In these performance expectations, students are expected to demonstrate proficiency in developing and using models and in obtaining, evaluating, and communicating information.

8PS05Chemical Reactions
Students will be able to provide molecular-level accounts to explain that chemical reactions involve regrouping of atoms to form new substances, and that atoms rearrange during chemical reactions. Students are able to apply an understanding of design and process of optimization in engineering to chemical reaction systems. In these performance expectations, students are expected to demonstrate proficiency in developing and using models, analyzing and interpreting data, and designing solutions. Students use these science and engineering practices to demonstrate understanding of the core ideas.
