Objective: SWBAT calculate equivalent resistance, current and voltage drop in a parallel circuit.
Warm Up: Diagram a circuit that contains a 12 V battery, a 3ohm resistor, a 5 ohm resistor, a light bulb with 1 ohm of resistance and a closed switch. Calculate the equivalent resistance and total current of the ciruit, as well as the current and voltage drop through each "resistor" (including the light bulb).

It's Tremendous Tuesday- brace yourselves for the peak of a solar storm due to hit us during class!
Objective: SWBAT review for tomorrow's test of Electrostatics and Electrical Energy.
Warm Up: I wanna give a shout out to the sun for providing us with an excellent event to discuss electromagnitism! What happens during a solar flare and why are scientists and cummunications managers so interested in them?

Objective: SWBAT infer data about point charges based on the fields that they generate.
Warm UP: On a computer, go to http://www.cco.caltech.edu/~phys1/java/phys1/EField/EField.html
Read the directions on how to use the Electric Field Applet. Place two point charges on your screen where the one on the left is a negative charge and the one on the right is a positive charge. What do you see? Change the one on the left to a positive charge of the same magnitude as it was previously and leave the charge on the right alone. Now what do you see? Why so these two situations produce different electrical fields?

Objective: SWBAT determine the efficiency of a heat engine.
Warm Up: Yesterday was a commuters nightmare in DC because the cold weather cracked some of the rails on one of the metrorail lines. Calculate the thermal contraction of a 20 m long steel metrorail line (whose coefficient of thermal expansion is 12 x 10^6) if the temperature drops from 32 oF to 12 oF.
