Many forms of energy can be considered to be either kinetic energy, which is the energy of motion, or potential energy, which depends on the separation between mutually attracting or repelling objects. Electrical potential energy is associated with the separation of mutually attracting or repelling charges. Gravitational energy is associated with the separation of mutually attracting masses. Thermal energy in a system is associated with the disordered motions of its atoms or molecules. Light energy is associated with the frequency of electromagnetic waves. Expand 10 7.3 None 3 Students will apply their knowledge of states of matter and phase changes in a game of Quiz-Quiz-Trade. Electrical energy is associated with an electric current in a circuit. Explain 20 4.2, 4.4, 5.4, 5.8, 7.3 None 3 Students graph their data and answer reflection questions about states of matter and phase changes. The following hands-on science activities from Science Buddies' library of STEM Activities for Kids can be used with students in or out of the classroom to explore states of matter science: Colorful Patterns in Melting Ice: colorful science activity helps students visualize and explore changes from solid to liquid. Polymers, Phase Changes, Physical Properties Middle School. Students will also discuss their classification system with their teacher and peers. Chemical energy is associated with the composition of a substance. In this activity, students will view, sort and classify pure substances and mixtures into the 3 common states of matter found in the laboratory. Elastic energy is associated with the stretching or compressing of an elastic object. Gravitational energy is associated with the height of an object above a reference point. Thermal energy is associated with the temperature of an object. Motion energy is associated with the speed of an object. Energy appears in different forms and can be transformed within a system.
