• 8th Grade Standards:
    Physical Science

     

    Quarter 1

    1. Students will understand that all matter is made of atoms, which are far too small to see directly through a light microscope. That elements have unique atoms and thus, unique properties. Students will also know that atoms themselves are made of even smaller particles.
    2. Students will understand that atoms may stick together in well-defined molecules or be packed together in large arrays. Also that different arrangements of atoms into groups compose all substances.
    3. Students will be able to distinguish among, explain, and apply, the relationships between mass, weight, volume, and density.

     

    Quarter 2

    1. Students will understand that the physical characteristics and changes of solids, liquids, and gas states can be explained using particulate model.
    2. Students will understand that mixtures of substances can be separated based on their properties such as: solubility, boiling points, magnetic properties, and densities.
    3. Students will be able to distinguish between physical and chemical changes, noting that mass is conserved during any change.

     

    Quarter 3

    1. Students will understand that there are different forms of energy, and those forms of energy can be changed from one form to another while total energy is conserved.
    2. Students will understand and recognize that waves such as electromagnetic, sound, seismic, and water have common characteristics and unique properties.

     

    Quarter 4

    1. Students will be able to identify and calculate the direction and magnitude of forces that act on an object, and explain the results in the object's change of motion.
