Exploring Energy and Matter

A professional development course for science teachers at the Exploratorium. 2015.

Day 1 Matter

Atomic Theory "All the world is made of atoms." R. Feynman

On the floor Exhibits:

Gas Model
Too Slow to Notice
Molecular Buffeting

Classroom:

Gas Model
Too Slow to Notice Evaporation using a microbalance

Measure the size of an atom Emuller from 10:30 to 12:00

Brownian Motion SL

Day 2 Conservation of Matter

Matter

Burn steel wool, candle measure mass change PD

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.
