Tuesday

We learned about alternating and direct current today. We watched a short video that demonstrated the movement of the electrons. Then we went to the lab and experienced that in D.C. the electrons move from the negative to the positive pole. We experienced open and closed circuits. We examined an A.C. wire and noticed that there are two parts, one that allows the current to go in and one that allows the current to exit.

We also wrote the metric prefixes down again so the students can use the prefixes in calculating metric changes.

To study for this lesson go to Youtube and watch Bill Nye on Electricity.
