Unit 7: Energy Transfer Model (ETM)
Unit 7 Learning Targets
“Create a model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.” (NGSS HS-PS3-1)
“Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative positions of particles.” (NGSS HS-PS3-2)
What these mean for you:
Conservation of Energy Videos
Walter Lewin from MIT- For the Love of Physics excerpt
Richard Feynman Conservation of Energy Lecture (7 min audio)
Use this worksheet to help take notes and check for understanding
Video of Feynman's Lecture
Energy Recap and Help
Common Types of Energy overview w/ teaching dialogue; how we began the unit w/ the "energy cheat sheet". Includes that filled in.
Getting the Most out of Energy Bar Charts (LOL Diagrams)
A nice overview of how to complete LoL diagrams and the storage and transfer of energy.
Simulations from the PhET Website (the first two use HTML5 so they can be done on a phone/tablet/computer; the third uses flash so it may not work on every device)
Energy Skate Park- good overview of Conservation of Energy; can also use this simulation at the bottom of the page
Hooke's Law Hooke's Law make-up lab handout
Masses and Springs- apply Hooke's Law
Physics Classroom Tutorials
Work, Energy, and Power- these tutorials introduce this unit opposite of the way we will cover it in class and in a different manner than we will cover these topics. We will eventually do everything found in these tutorials (most of it at least) just not in the same order.
