Tree and CO2
Day 3 Energy: Forms of energy
All forms of energy can be 100% converted into heat(flow)
Kinetic Energy, Potential Energy, work, mass, thermal energy
Classroom
Energy Transformation Examples.
Burn a peanut Calorimetry plus engineer a better calorimeter
Measure the Power of the sun
Efficiency, measure a solar cell.

Day 4 Conservation of Energy
Exhibits
Pendulums
Resonant Pendulum
: Gravitational Potential and kinetic Energy sum is constant
Orbits: Gravitational potential and Kinetic energy, sum is constant
E=Mc^2
Day 5 Temperature ?
A thermometer in contact with an object has the same temperature as the object. In the1800s Temperature was defined for an ideal gas thermometer as the average random kinetic energy of translational motion per molecule.
In the 1900s temperature is the negative derivative of internal energy versus entropy T = - dU/dS.
