8th Grade Standards:
- 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.
- 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.
- Students will be able to distinguish among, explain, and apply, the relationships between mass, weight, volume, and density.
- Students will understand that the physical characteristics and changes of solids, liquids, and gas states can be explained using particulate model.
- Students will understand that mixtures of substances can be separated based on their properties such as: solubility, boiling points, magnetic properties, and densities.
- Students will be able to distinguish between physical and chemical changes, noting that mass is conserved during any change.
- 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.
- Students will understand and recognize that waves such as electromagnetic, sound, seismic, and water have common characteristics and unique properties.
- 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.
