SL Core D- Week 26 (Week 52) Dec.26-30th 2011

We are still sick and ambling through as we hope to recover, so we haven't completed very much.  We have added in a few new books to this week and should be using them as we go forward:

We have brought back one of our favorites from Core 2--Geography Songs!!!  Back by popular demand!  This week we are studying Continents and Oceans.

Geography Songs by Kathy Troxel
We have started a new Lamplighter book:
 The Bird's Nest (Rare Collector Series) by Christoph von Schmid
*we read the first short story called "The Bird's Nest"
Dd's Reader is:
Lots of Piano playing this past month; since we rec'd the new gift of a piano.  This week's favorite is Ode to Joy.

We finished our audio of THe Lion, THe Witch, and the Wardrobe by C.S. Lewis

Math--Teaching Textbooks-lesson 48

Some fun books Dd's read this week:
All-Action Classics No. 3: The Odyssey by Homer, Tim Mucci, Ben Caldwell and Emanuel Tenderini


We went to the Children's Museum this week.  We went to see a play specifically; but also saw a lot and had a great time.  These colorful pictures are from the Dale Chihuly's Fireworks of Glass exhibit:











The Lily Theater presented Dorothy and the Wizard in Oz : 







Some crafts from this week: 

Dd loves to make these mosiac pieces--very fun!



Dd's drawing of a mermaid in the sea

Dd got wooden tinker toys for Christmas and made this airplane/helicopter piece


At the Science Lab we did the following project:
DNA Extraction from Wheat Germ  (no pictures from this great experiment)
The DNA in raw wheat germ is enclosed in the nucleus of the cell.  To extract the DNA we must first break open the cellulose cell wall by vigorously shaking a mixture of cells and warm water.  The warm water (between 55 and 60 degrees Celsius) will deactivate an enzyme in the cell that can break down DNA.  After the cell wall is broken down our next barriers are the cell membrane and nuclear membrane.  The warm water will melt the membranes and soap can be added to dissolve the lipid layers.  Once the DNA is free in the mixture, it can be precipitated out by adding a layer of ethanol.  The DNA precipitates out because it is insoluble in ethanol and now the DNA can be spooled onto a wooden stick for collection.  Dd was able to get a very good sample of the DNA into a small beaker that we were allowed to take home.

Then dd worked at the Microscope Table.  She did a great drawing of a Garden Spider from viewing it under the microscope.  



Then we built a DNA Model out of pipe cleaners of various colors and macaroni of various size. 



This is suppose to be a DNA "double helix"- a twisted ladder- The colors of the pipe cleaners represent the chemical "rungs" of the ladder.   


Then we went upstairs to the Science Port - the experiments there revolved around archeology.   We looked at rocks under the stereo microscope; played on the big screen computer to put puzzles back together, Dd made a replica of a Egyptian Mummy (should have taken a pix of that!), and made molds of Chinese Warriors in some cool clay magic and mold forms; and she made this colorful -take home piece:
