A typical automotive oil may be rated as "5W-30."
Explain what this means.
"5W" is the indication of viscosity at the "winter" temp, or while it's cold.
"30" is the indication of viscosity while it's hot.

Double Points!! (quadruple if you already have the x2 multiplier)
Draw the formula for Ohm's Law
(regular points if you can at least identify the 3 variables)
E = I * R
E = Voltage (Volts)
I = Amperage (Amps)
R = Resistance (Ohms)
