ENERGY TRANSFER Energy Unit NGSS KCAS 7 th Grade Science

TEMPERATURE & HEAT

TEMPERATURE  Measurement

HEAT  Form of Energy  Has Kinetic Energy because molecules are moving

 More Mass = More Volume = More Energy  Lower Mass = Lower Volume = Lower Energy

 More Mass = More Volume = More Energy  Lower Mass = Lower Volume = Lower Energy

FIREWORK  Chemical (PE)  Thermal, Sound, Mechanical (KE), Chemical (KE)

HEARING  Sound or Mechanical (PE)  Sound, Mechanical (KE)

CIRCUIT  Chemical (PE)  Light, Thermal, Electrical (KE), Chemical (KE)

LAW OF CONSERVATION OF ENERGY  Some energy transfers are not useful, resulting in lost energy

 Be familiar with/know how to read  Won’t be tested
