Class 11/20/08

In today's class we covered what our "Bell Ringer" final projects were supposed to be about. I am really happy that we are doing another project vs. having a final test. I think projects are more beneficial because they are hands on. Finals just require memorization, and then you can for get about the information after you take the test. Then, we covered part of our reading guide, which was also helpful because I am having trouble understanding electric currents. Dr. E gave many demonstrations in class on how electrons are transfered, and it helped me to see exactly what the book is talking about. Finally, we started working on a lab called " Electroscope." We made an electroscope by using plastic tape and haning it from straws. The tape can gain or lose electrons when you stick it to a surface and rip it off. By suspending the pieces of tape on the straws and holding the balloon up to them, we could tell which pieces of tape were positively or negatively charged. We haven't had time to finish the experiment yet, but we will next class period!
