Stem Cell Success Stories

Research what, if any, success scientists have had with stem cells in actually treating a human or animal health condition.  Using our CollaborizeClassroom site, post a summary of one success story.  Be sure to state whether the scientists used embryonic or adult stem cells in the treatment.  No two students can post the same story so first come, first served.  Be sure to cite your source.

Inside the Cell Reading and Stem Cell Debate

I will not be in class on Monday, 9/17/12.  Students who have biology that day should read, in class, the preface and chapter 3 in their ‘Inside the Cell’ book.  If you have not received your books in the mail yet, I have a classroom set that can be used during class only.  You can not take them with you.

My D-period biology class will do the above on Tuesday when we meet. (I’ll be back in class for that)

All biology sections should also go to our Collaborize Classroom site and participate in the Stem Cell Debate question.  You must post your position and at least two responses by Friday, 9/21/12, 11:59:59pm.

Welcome to Biology

Welcome to biology!  We have a lot of very cool things to learn and do this year, so let’s get this party started.  😎

  1. Go to http://docfleetwood.collaborizeclassroom.com and register for an account.
  2. Go to http://docfleetwood.net/wiki/tiki-index.php?page=Biology+List+of+Items and follow the instructions there to order or subscribe to various materials necessary for class.

Protein Test

You will have a test on proteins on Monday, 5/7/12.  The test will include everything we covered related to proteins, such as: structure, function, transcription/translation, protein folding, peptide bonds, RNA vs. DNA, enzymes, inhibition, digestion, immune system, blood types, The Structures of Life book, etc…

You will be provided with a codon table to determine amino acid sequences.

Here is a picture of a list of terms generated by my G-period class.  It may not be all-inclusive but should help.

Molecular Workbench Diffusion and Osmosis

Log into the molecular workbench software and complete assignment #10: Diffusion, Osmosis and Active Transport.  Be sure to click the links in the green boxes on some pages to complete all the sections and create a full report.  Don’t just keep hitting the ‘next’ button at the bottom of the page or you won’t see everything and won’t get full credit.

Due: Friday, 4/27/12

 

The DCAS is Coming

On May 1st, biology students will take the ‘End of Course’ biology DCAS assessment.  Here are some links to help you get ready for that test.

  • There is a practice test located here https://dept.tds.airast.org/student/
  • I have collected the ‘End of Course Specifications‘ for biology as a PDF document.  You can use that to see everything you are expected to know for the test.
    • Make sure to pay special attention to the items given a ‘priority’ of ‘essential’
    • You can mostly ignore the items given a priority of ‘compact’
  • For items we have not covered in class yet, you should go to my biology page and click the appropriate links to investigate those topics.  Here are the items I suggest you look over that we won’t get to before the test.
    • Diffusion and Osmosis – I will be assigning a Molecular Workbench activity this week to address this.
    • Punnett Squares – I have a general description and lots of practice opportunities available on my wiki page.
    • Dominant and Recessive relationships and Genotypes and Phenotypes – you can look these up most anywhere, but we will also be covering them this week in relation to blood types and blood type inheritance.
    • You might also want to read through the Classical Genetics section at the DNAFTB website
      • pay particular attention to #11 – which details ‘crossing over’ during meiosis.  This just means that parts of the homologous pairs of chromosomes swap a section of DNA.  The end result is more variation in the offspring, which is one reason that sexual reproduction gives more variation than asexual reproduction.
    • Energy – Photosynthesis and Cell Respiration – you can mostly just read the appropriate sections of the ‘specifications PDF’ above.  It will list the facts you need to know.  For the chemical equations you can see my wiki pages on photosynthesis and cell energy (as well as many other sources).
    • Cells – to learn about cellular organelles and about meiosis and another view of ‘crossing over’, you should read the Inside the Cell book from NIGMS.  We are going to read this book soon anyway, so you might as well do it now.  It is a very interesting tour through the cell and discusses many things we can and can not do with regard to disease and aging.  It is by the same people who wrote the ‘Structures of Life’ book.  I also have copies in school of the physical book if you want to read it during activity period or your study hall.
  • Also, don’t forget to use your textbook as a source of information.  After all, it is written with students in mind.
