Old UPDATES that are probably no longer relevant


Online Class Lesson and Communication News

UPDATE - May 19 at 1:02 AM: I will soon be sending out e-mails with the Final Exams attached. The cover letter for that e-mail is in a pdf file at Final Exam Cover Note so it can be studied before opening the exam. Be sure to respect the honor system when taking the exam.

UPDATE - May 11 at 0:39 AM: I have sent out the Chemistry Midterm Tests, but there are many Quizzes that I have not gotten back to grade. Please try to get them in so I can grade them and get feedback to you before you need to take Chemistry midterm and Final.

UPDATE - May 10 at 4:00 PM: I have now posted Information about the Chemistry Midterm and Final Exam.

UPDATE - May 9 at 3:53 PM: Just before social isolation, Angelica Morfin had asked in lecture about the cost of healthy eating. Here is a note about that interrupted discussion. It is not part of the Science-1A course.

UPDATE - May 8 at 02:26 AM: I have now posted May 6 Lecture Notes. These notes are to help you prepare for Quiz 8 which will be sent out shortly.

UPDATE - May 7 at 05:10 AM: I have now posted Week 17 Lab Notes which are about Nuclear Physics. This has quite a bit to read and view, but is quite important. This is the end of the lab activity. Next week is the Chemistry Test which will be due Sunday, May 17, so I can grade and get it back to you before the Final. I will get Quiz 8 out tonight. Consider May 10 the due date for Quiz 7 and May 15 for Quiz 8 so I can grade them and get them back to you before the Chemistry Test is due.

UPDATE - May 4 at 04:45 AM: I have now posted May 4 Lecture Notes. These notes are to help you prepare for Quiz 7 which will be sent out shortly.

UPDATE - May 2 at 02:32 AM: I have now posted Week 16 Lab Notes and April 29 Lecture Notes .

UPDATE - April 28 at 2:09 PM: Due date for Quiz 6: Consider the end of Sunday, May 3 to be the due date for Quiz 6. Also, for those of you who have a personal address as well as the school address in my address list and therefore got two different quizzes, choose one without comparing them and ignore the other.

UPDATE - April 27 at 11:27 PM: Oops! just fixed a bad link in the April 27 notes mentioned 17 minutes ago.

UPDATE - April 27 at 11:10 PM: I have sent out e-mails with Quiz-6 questions and have posted April 27 Lecture Notes which give detailed advice on how to prepare for it.

UPDATE - April 27 at 1:20 AM: I have sent out e-mails with the grading of the Physics Midterm. I have been getting a lot of Quiz 5s, but have neglected to acknowledge them individually. I will probably be grading them at the end of the week.

UPDATE - April 22 at 5:50 AM: I have sent out e-mails regarding Quiz 5. Also, could the student who asked about the contradiction between eating healthy and cost contact me. I'd like to know what you learned in your investigations.

UPDATE - April 20 at 1:03 AM: I have added April 22 Lecture Notes.

UPDATE - April 18 at 1:59 AM: I have just sent out e-mails to everyone about newly added notes and Quiz 5 preparation. See April 20 Lecture Notes and Week 15 Lab Notes. The Quiz preparation material is in the usual place .

UPDATE - April 13 at 3:20 AM: I have just sent out e-mails to each of you with your Physics Midterm Test and some notes about taking it. Let me know if somehow you did not get it. We will get though this challenge. Good Luck.

UPDATE - April 11 at 8:58 PM: I have sent reminders to students that still need to do some of Quizzes 1-4. Also, I have still been unable to contact Brenda F. and Breanna G..

UPDATE - April 10 at 4:13 AM: I have added Lecture Notes for April 15, 2020 below. These Notes are useful for Quizzes 5-8 and the Chemistry Midterm, NOT for the coming Physics Midterm.

(There will be no Lab notes for April 13-15 since that is our Physics Midterm Test Week.)

UPDATE - April 9 at 3:06 PM: I have added Lecture Notes for April 13, 2020 below. These Notes are useful for Quizzes 5-8 and the Chemistry Midterm, NOT for the coming Physics Midterm.

UPDATE - April 4 at 7:50 PM: I have added Lecture Notes for April 1, 2020 below. These Notes have advice useful while studying for the Physics Midterm.

UPDATE - April 3 at 5:40 PM: I have added Lab Notes for Week 12 - March 30 and April 1, 2020 below.

UPDATE - March 30 at 10:31 PM: I have added Lecture Notes for March 30, 2020 below.

UPDATE - March 30 at 4:54 PM: Our Physics Midterm will be after Spring Break. Right now I am trying to get students caught up with Quizzes 1-4. Here are the contents of an e-mail I just sent out about quizzes and tests:

This on-line process will require that you operate on an honor system. Specifically, you must not look at the Practice Quizzes and Test material while doing your quiz/test work. No quiz should require more than 1 hour of effort with coming Chemistry Quizzes being much faster. The work, of course, must be your own.

Also, you should use the Equations sheet at http://yosemitefoothills.com/Science-1A/EquationAndSymbolNotes.pdf unless your own Equation Sheet is unmarked. You can print out a Test version from the web site if needed.

Let me know if you have any questions. This is not nearly as efficient or effective as when we can meet in a classroom, but let's make this work!

UPDATE - March 30 at 11:39 AM: I sent out e-mails early this morning giving the current points for Quizzes and Calculations Test as well as returning via scanned copies graded quizzes that I had from the last Wednesday we met.

UPDATE - March 28 at 10:02 PM: I have added Lecture Notes for March 25, 2020 below.

UPDATE - March 27 at 5:05 PM: I have added Lab Notes for Week 11 - March 23 and 25 below.

UPDATE - March 27 at 2:07 AM: Here are the contents of an e-mail that I sent out to everyone.

My younger daughter sent me the following link to a Washington Post article entitled "Why outbreaks like coronavirus spread exponentially, and how to 'flatten the curve'" which I feel is worth passing along to Science-1A students. I'm hoping that it can be viewed without any cost.

Virus Simulation

I'm sure you appreciate the connection between rabbit reproduction, our hydrogen-oxygen explosion, Walt Disney's ping-pong ball and mousetrap demonstration, nuclear bombs, and the current Coronavirus pandemic. When you understand one, it is much easier to understand the others. This is for your enlightenment. You will not be tested on it.

UPDATE - March 26 at 8:50 AM: Everyone should have received an e-mail announcing that this server is up again. I'll have a new handout in about 24 hours.

UPDATE - March 25 at 10:20 PM: Networking problems remain. It seems that you can access this by using http://64.118.100.243/Science-1A or from a network cache, but not using http://yosemitefoothills.com/Science-1A/ .

UPDATE - March 25 at 8:43 PM: I had an abrupt failure of the DSL Modem connecting me to the Internet at 12:08 PM today which cost many hours to find a workaround and re-work my firewall and router. I am still working on getting e-mail working, but it appears that the web server is working. This has delayed my preparation of this weeks Lab summary and the March 25 Lecture summary.

UPDATE - March 23 at 2:45 PM: I have now added today's lecture at Lecture Notes for March 23, 2020 to the section below entitled "On-Line Lecture and Lab Notes". Also, I have still not received e-mails from McKayla G., Breanna G., Andre T., Jaclyn W., Taylor E., and Brenda F.. I need to know if they are still with us.

UPDATE - March 21 at 8:24 PM: I have now added a pdf file entitled Lecture Notes for March 18, 2020 in the section below entitled "On-line Lecture and Lab Notes". Please read these. I proofread them 4 times, but let me know of mistakes or unclear sections. Lecture Notes for March 16, 2020 were posted a few days ago.

I am still thinking about quizzes and tests and may do them by e-mail making the questions true/false, multiple choice, or fill in the blanks, but not writing equations nor drawing diagrams. Still, the questions will be designed to test the same facts learned by studying the Practice Quizzes.

UPDATE - March 20 at 3:24 PM: I have added a pdf file entitled Lab Notes for Week 10 - March 16 and 18, 2020 in the section entitled "On-line Lecture and Lab Notes" below. Read those notes and observe the animated gifs mentioned there which are at http://yosemitefoothills.com/Science-1A/#molecules.

UPDATE - March 20 at 1:16 AM: I have removed obsolete updates. I still need confirmations of receipt of my e-mail test from McKayla G., Breanna G., Andre T., Jaclyn W., Taylor E., and Brenda F.. Please send a message to science1a@yosemitefoothills.com to confirm that you can get the e-mails and can see this web page.

UPDATE - March 18 at 1:14 PM: We will make this work!!! One student sent me the following message "Hello Professor, I'm confirming that I receive your email. Just a heads up, if students like me do not have internet access at their home, I found out that Comcast (Xfinity) is letting college students sign up for two months free of charge during this difficult time. I just signed up, and was approve this includes free installment. Students can find the information on the Clovis campus website! Thank you!"

UPDATE - March 17 at 9:51 PM: I have created a section on this page entitled "On-line Lecture and Lab Notes" and placed within it my first pdf file of notes. Please take your time to read these carefully and follow their links. Speed reading science is a bad idea. More will be added as I can create and proof-read them. Let me know by e-mail about errors or parts that are unclear.

UPDATE - March 17 at 5:19 PM: I have watched an instruction video about the Zoom on-line system the school uses and really do not want to use it. Also, my Internet speed is probably inadequate for it.

UPDATE - March 16 at 9:27 PM: I sent out an e-mail message with the subject "TestEmailToAllStudents" at 5:18 PM today and have been getting "Got it" messages back. I am adding personal e-mail addresses to my address list when requested. The e-mails are being separately sent so that the addresses are not being shared the way mass mailings often do.

UPDATE - March 14 at 00:55 PM: I sent the message in the following link to all students via e-mail. If for some mysterious reason you did not get that e-mail, send me a note at science1a@yosemitefoothills.com and I will try to figure out why. I need to be able to count on e-mail messages getting to all of you.
