Apologia Biology—still here, but stalled.

Update:  We met today to create new blogs and concept maps.  Total recall app is the one I recommend for iPads or iPhones.  Here is a review of other sites.  The kids are creating blogs now for the Designer Baby Project.  Finally.

We met on Thursday last week to finish the Carbohydrate, Fats, Sugar, and Protein lab tests.  I was afraid it would become the never ending lab.  After Christmas, we are weathering snow and flu.  I hope to meet again Thursday this week.  My goal is to have the kids make the different molecules and describe how they are different.  I’d like them to revise their lab notes, too.  We’re going to start the Designer Baby Project next.  I need to have the kids learn how to create blog posts and use different software apps.  Don’t give up!  I’ll be back.

Apologia Biology: Carbohydrates, Lipids, and Proteins Lab

BTW, this exercise coincides with the Organic Chemistry section in Module 5 of the Apologia textbook.). The class is focusing on the biomolecules.  I plan to teach Chemistry next year to most of the class.  I’ll teach them about the Periodic table, Iona, molecules, and balancing equations then.  So, the kids are learning a bit of biochemistry.

Once the kids finish the Biomolecules exercise, they'll work on the labthe detection of carbohydrates, proteins, and lipids.  The Bio class will use these tests(Here are photos.)  Next week, we have two classes, both of which will be this lab.  The goal is to understand what carbohydrates, lipids, and proteins are.  Here's hoping for good results.

Apologia Biology: Designer Baby Project

My class is working through biochemistry right now.  I’m prepping a project, Designer Babies.  So far, I started a scoring rubric and have amassed a number of links which are germane.  This article, “Ethics of Designer Babies” is a good place to begin.  Below is the announcement on my Google Classroom page.  As a devote Catholic, I follow Church teachings.  But, I believe the children should struggle through these thorny issues.  As a mother, my heart grieves for infertile couples and families with a sick child.  I firmly believe these are moral issues, not merely controversial ideas that make interesting ethical debates.  One apect is the fear of creating a class of ‘genetically elite’ children rather than the millions of embryos destroyed during IVF.   It appears creating  a ‘genetic elite’  supersedes all of the moral issues. So, my class is going to prepare blogs.  Below is the overview.  I’ll post links in the next post.  Once, we begin, I’ll post screen shots of class submission…

Apologia Biology: Biomolecules (Module 5–Organic Chemistry)

Yet another update...We have snow.  The kids may never finish working on their molecules.

Quick update: This is going to take awhile to finish.  But it’s so important!  I want them to understand complete carbohydrates are formed from glucose and sucrose is the product of glucose and fructose.  I believe this foundation is key to understand before tackling complete structures such as DNA.  We’ll be working through these structures at least one more class and likely two.

Update: Here is another molecular worksheet if your kit doen’t provide one.The website allows parents to request a key.). Frankly, I prefer the Labaids materials in their kit.

We need to do a little chemistry, beginning with biomolecules.  Our class is using this kit with the handout in the kit.  This exercise takes forever.  Any molecule set works!  Since there are 19 kids in the class, I ordered the Molecules of Life kit.  If you are working alone, this inexpensive kit works perfectly.  Goodwill ( fre…

Apologia Biology: DNA Extraction Lab

Update: The last photo has a decent shot of the DNA.  It is white threads which float into the alcohol.

Update:  This week (after Thanksgiving) we're doing the DNA lab.  Yesterday's class went as expected.  The girls extracted mounds of DNA; the boys all need to try again.  See pix below.
Tomorrow, we're doing the DNA extraction lab with split peas--the instructions are in the Apologia textbooks.  (The first edition uses onions instead of split peas.  The link has directions for extracting DNA from just about anything.)  The key is to use fresh meat tenderizer.  My class is doing the lab as an inquiry project.  I bought three types of alcohol: denatured ethanol, and two different percentages of isopropyl or rubbing alcohol.  I also bought salt with and without iodine.  My materials include two brands of dish detergent, shampoo, and hand soap (clear).  The students will hypothesize which factor produces the most DNA.  (Remember, it's fresh meat tenderizer.)  The kids ar…

Apologia Biology: Mitosis and Meiosis

Yesterday, we had an organelle quiz and resumed work on the mitosis and meiosis yarn models.  The kids are using the diagrams from the text book to create and label.  I know that this activity may seem pointless--it's not!  In the past, I had the kids use yarn, petri dishes, and chalk to duplicate the stages of mitosis and meiosis on lab desks.  It's like drawing microscope slides; it forces the child to study the diagram more closely and involves other parts of the brain.  Yes, it does take loads of time to do well.  I sent home a boat-load of coloring pages to complete--due after the Thanksgiving break next week.  On Thursday, we're doing the DNA extraction lab.
