Weekend HW

The non-extra credit (ie mandatory) part of Paperclip Meiosis is to make a document with a picture and description (can be bulleted list) of each of the phases or steps listed on the assignment.  Finish up any descriptions you need for the Paperclip Meiosis.  Make sure you turn it in to your folder when you are complete.

If you made a movie (that is, if you are the person with the movie on your iPad), send me an email and I will add you to an iCloud photo album.  Then look for an email with an invitation to the Meiosis photo album.  From Lego Movie Maker, upload your movie to your camera roll, then you should be able to share it to the Meiosis album.  You have until the end of the quarter to turn in the movie for extra credit.

Continue reviewing for unit 2D quiz.  Outline in the 2D folder.

HW tonight: Meiosis reading

HW tonight is the meiosis reading in the Unit 2D folder.  Reminder that there will be a quiz on Unit 2D next week (Tuesday/Wednesday).  Review outline in the 2D folder.

First day back

Welcome back- I hope you all had a restful break.

Coming up we will be wrapping up Unit 2D with meiosis.  Quiz on all of Unit 2D will be on 1/13 and 1/14.  Check the folder for the study outline.

HW tonight:  begin reviewing for quiz next week.  Also make sure your Drive folder is up to date, including Osmosis lab final, strawberry lab, stem cell thing (from in class on the laptops).

Mitosis notes

Jellies (and Squids if you want them)- There is a new PDF of the mitosis slides with notes added, since I was out for the lecture yesterday.  Review them over the weekend and I will clear up any questions on Monday.

For everyone- continue working on your osmosis lab final.  Email me if you have questions (I won't be checking comments on the document until I grade the finals).

Squids- Finish up the stem cell activity if you didn't finish it in class.

In class work Wednesday Dec 17

Good morning Jellies,

I am out sick today. In class you should do your best to fill in the Mitosis notes found in the Unit 2D folder. You can use the reading (mitosis reading, 2D folder) or other online sources to help you. The most important part will be recognizing the phases of mitosis- the reading has some nice pictures. We will do a lab tomorrow and then fill in any gaps in your notes next class. Be sure to do the activity on the last slide (only takes about five minutes). 

Mitosis homework

Homework after the mitosis (PMAT) lecture: finish the mitosis reading on the stages of mitosis.  Continue to work on lab final (due Tuesday).

Monday night HW

Read pp 82-84 in the mitosis reading found in the unit 2D folder.  You should continue working on your lab final as well- those are due next Tuesday (last day before break).

Weekend HW

-Make sure you have completed the notes on Lessons 17-20 (17 and 18 we did in class.  If you are doing these on your own, note that we only did the last third or so of lesson 18).

-Answer the questions on the strawberry lab and share in your folder.  If you didn't do it in class you can do it at home- it only takes 10 minutes and everything you need you can get at the grocery store.  Use rubbing alcohol for the ethanol and an unfolded paperclip for the extraction loop.

-Read and take notes on the DNA replication reading in the 2D folder.  Pay attention to the steps of replication as well as the purposes of the three enzymes helicase, DNA polymerase and ligase.

Here is a really good animation of DNA replication (but unfortunately it doesn't work on iPads).  Don't worry about the RNA primer or about any of the enzymes besides the three we discussed in class.

**ALMOST FORGOT!!***  I am in the process of giving feedback on your osmosis labs.  Jellies are all done.  Squids, I will be done with yours by the end of the day today.  Finals are due Dec 23rd.  Remember to check the rubric in the Unit 2C folder.

Wed night HW

If you have access to a laptop or desktop, finish up your notes through the end of Lesson 19.  Then do the following:

Read the Wikipedia page on Rosalind Franklin.  Hers is a famous story in science about the failure to recognize the work of all contributing individuals as well as the sexism that was common and accepted at that time.  

Note: James Watson, one of the two scientists described in this lesson, worked as director, president and chancellor at Cold Spring Harbor Laboratory (the institution that runs the dnaftb.org site) for nearly 40 years.  This may explain why there is no hint of controversy over Franklin’s contribution in Lesson 19, although nearly all other publications at least mention this in passing.

HW after quiz

The link to the page with the animations is here.  Remember that the animations do no work on the iPad.  Additional information about the three experiments we looked at in class can be found here.

For homework, read this page which summarizes the work of Watson and Crick to elucidate the structure of DNA.  We will look at that animation (lesson 19) in class.  I highly recommend using printfriendly.com to convert the webpage into a PDF that you can bring into Notability to take notes on.
