Light and SoundLight is a form of energy that travels in waves. A reflection occurs when light rays bounce off a surface, such as when you see your reflection in a mirror. Absorption is when an object takes in light wave. Refraction is when light bends moving from one medium to another. Sound is a type of energy that travels in waves that is caused by vibrations. Vibrations are movements made rapidly back and forth. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 3

Objects and substances can be classified by their physical and chemical properties. Mass is the amount of matter (or ''stuff'') in an object. Weight, on the other hand, is the measure of force of attraction (gravitational force) between an object and Earth. The concepts of mass and weight are complicated and potentially confusing to elementary students. Hence, the more familiar term of ''weight'' is recommended for use to stand for both mass and weight in grades K-5. By grades 6-8, students are expected to understand the distinction between mass and weight, and use them appropriately.
