Electric Circuits

We are learning about electric circuits in physics. Circuit elements and electric current is the topic for today. Specifically Capacitors, which store electric charge.

Coulombs Law Lab

The Coulombs Law Lab link that I provided is missing a bit of the title so all you get is an error message. Add "tml" to the link URL and you will see what I intended. I plan to change it Monday. The real link is below

Monday Physics Fair

Hey, don't forget. Monday is Physics Fair in the Gym at Mounds View High School.

Third hour kids. Be here early (6:30 - 7:00 AM) to set up for Channel 11. They will be filming at 9:30 - 10:30 AM.
