March 4th Scribe
First we went over the test, then we found out that test corrections were due on the 5th because five week grades were due at that time as well. Then Mr. Wirth asked the question, What do you know about electricity? Their were very few responses, but the class was eager to learn the wonders of electricity. In the beginning of class we did some amber demos. then we used the rubber and glass and rubbed them against silk and fur to see the power of static electricity. This is where we found out that opposites attract and that water attracts to both rubber and glass. Then we learned about the electroscope, and how positives repel each other. Next Mr. Wirth showed us the magic water and how it attracts and repels to different materials. It is important to know that static electricity is not actually static, it is in fact moving. Also, electricity comes from matter. Another important fact to remember is that protons never leave because that would change the atomic number of the atom. Hopefully for anyone that needed a refresher or was not in class, this will be an effective tool.
