NGSS (Partial Coverage):

4-PS3-2: Energy Transfer. Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents. (Energy and Matter)

MS-PS3-4: Thermal Energy Transfer. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample. (Scale, Proportion, and Quantity)

HS-PS3-3: Energy Conversion Device Design. Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy. (Energy and Matter)

TEKS:

6.8B Describe how energy is conserved through transfers and transformations in systems such as electrical circuits, food webs, amusement park rides, and photosynthesis.

Explore the fascinating world of thermoelectricity, where heat is converted into electricity and vice versa through the use of conductors and semiconductors. Students will qualitatively observe energy transformations using a thermoelectric module, while investigating the relationship between temperature and electric potential through the Seebeck and Peltier effects.
