Beginning next week (September 3, 2007) there are clothing requirements for laboratory. You not the rules, please remember. Students will not be allowed in laboratory with shorts are any type of open-toed foot wear.Remember laboratory experiments begin next week. There are no Monday labs due to Labor Day, but all other labs will meet. After class on Thursday you should be able to PS1.1, PS1.2 and PS1.4. Go ahead and try PS1.3 (look at Exercise 1.12 in your textbook). After you have completed PLE#2 you should work of PS1.5 - PS1.7. PS1.8 - PS1.10 are more challenging conversion problems. Someone may ask about those problems in class on Tuesday. If you have completed PS1.1 - PS1.7 by Tuesday you will be in a good position to work on the last three problems in PS1. Next week for laboratory you need to bring: 1) the handout you received in laboratory this week; 2) a calculator (graphing is OK); 3) your textbook. Following check-in of your locker you will work on an in-class exercise to practice doing problems from Chapter 1 of your textbook. Be sure to have completed PLE#2 before arriving in laboratory. Print out the Expert's response page and bring that with you to lab also. PLE#2 and ACA#2 are now available on your Personal Page. You will need a calculator and your textbook for the PLE. When expressing your answer in scientific notation (like 4.56 x 103) on the PLE or ACA enter the number as 4.56e3 (like you would when using Excel spreasheet). Here are some questions that were posted on ACA#1 from students and my responses. I'll try to answer more and post them here. HAve more questions? Ask away.
