Test Day

Today was everyone's Chapter 17 and 18 exam and everyone starts with Chapter 19 tomorrow. This next chapter centers on electric current and resistance, a prelude to our work with electric circuits in Chapter 20. C Block has lab tomorrow and that investigation will focus on Ohm's Law, which pulls the three biggies in electricity together in one package - voltage, current and resistance. The reading you were assigned for tonight (p. 700-701) goes over Ohm's Law and should help you with the discussion questions/conclusion for the lab.
