Electricity! Optional Assignments, HMWK due Friday

Notes: Circuits

Sims to experiment with class on Thursday:
John Travoltage
Build an Atom -  click on "show stable/unstable" and try to build various neutral, charged, stable, and unstable atoms.  See if you can find out what the word "ion" means.
Balloons Static Electricity Optional Assignment
Due 2/27
This last one won't work on Chromebooks but will work at home and is more of a game:
Electric Field Hockey Optional Assignment
Due 2/27

HMWK due Friday: Read p. 392-399, including the page on lightning.  
 p. 399# 1-7  Use Sig Figs properly.

Last week we tried looking at some topics in Astronomy in a different way to cover lost ground based on test results.  We also started experimenting with concepts such as electric charge and induction.  (electrostatics notes in last post).
Today in class we worked with a Wimshurst Electrostatic Generator and a Van de Graaf Electrostatic Generator and saw some extreme examples of induced charge with tens to hundreds of thousands of volts.

Wednesday we'll finish demonstrations with electrostatic induction and go over homework that was turned in on Monday.  Mrs. Greene, the Honors Chemistry I teacher, will also stop by to go over your work on the algebra skills pre-test answers and to share details about Honors Chemistry with you.  If you have any questions, we will have a visit on either Thursday or Friday from some past students who will be candid with you about their experience.

Thursday we'll set our sights on a new beast; adding to voltage - Current and Resistance in circuits.

Friday you can count on a quiz over concepts and perhaps a tiny bit of math... with sig figs tested.
