Today’s Targets I can identify the transfer of energy among the 6 “Forms” of energy (#3) I can use the Conservation of Energy and the mathematical definition of PE and KE to solve calculations questions about falling objects. (#7) I can explain how heat, temperature, and thermal energy are all related (#8) I can describe how thermal energy is transferred through conduction, convection and radiation (#10)

Today’s Agenda Warm-Up (distribute quiz #1) Quiz #1 review and preparation for tomorrow’s requiz Heat Engines….a simple energy transformation
4
Warm Up Make an energy chain for the following: A wind turbine charging a battery A solar powered car A battery operated flashlight A battery operated radio A person playing the piano
5
Quiz Review Woah…. Let’s take a look at the most missed problems in preparation for tomorrow’s re-quiz

Warm-Up A measure of the TOTAL kinetic energy of the particles that makeup an object is that object’s _______________. This is measured in __________. A measure of the AVERAGE kinetic energy of the particles that makeup an object is that object’s _______________. This is measured in _________. The flow of thermal energy is called ______________. This is measured in _________. When materials are heated, the particles move ____________ and generally take-up more _______________. This is called _____________ ___________. Materials generally increase more in _____________ than _____________. (cold vs hot ring) Thermal Energy can be transferred in what three ways? Draw an energy chain for the following PHET examples: space Joules Temperature Kelvin Heat Joules faster Thermal Energy Thermal Expansion length width Conduction, Convection, Radiation

Remediation Time! Tomorrow, you will receive your quiz #1 back. After completing the remediation sheets that you picked-up on your way into class today, you will have an opportunity on Thursday (during class) to redo quiz #1. Let’s spend the time now breaking-down the steps to solve PE and KE problems.
