Kindergartener
Ok, he listened to the hymn with us and looked at the bacteria under the microscope, but other than that, he got into everything...ransacked the living room...trashed his room...jumped on the couch and looked out the window, screaming...it was not a good day. sigh..
13 and 15 Year-olds
They mostly worked together today on Bible and finishing the bacterial colony lab. 15 year-old also read The History of Medicine and worked on her Health course. She also had her Musical Theater class at the enrichment center.
Bible
- Hymn Study - read the background info for the hymn "Amazing Grace" and listened to a version of it
- Saint Study - we didn't do a saint study this time, because we did the Angels & Demons study from this Lutheran Homeschool site: https://www.lutheranhomeschool.com/product/angels-demons-a-bible-study-anthology/ This study was incredible. We worked through the entire thing (all 50 pages) in one sitting. We spent a bulk of our time on Christian Dogmatics by Theodore Mueller, published in 1934. Excellent! The reason why we did this study in one sitting is because the teens didn't want to stop reading it.
Bacterial Colonization Lab
Procedure:
- 10 agar plates with 10 sterile swabs
- The teens dampened each swab with sterile water
- They swabbed ten different household items
- They ran the swabs over the agar plates
- Plates were sealed and place in a warm, dark area for 4 days
- We opened the plates today and compared bacterial growth between the 10 items
- We took samples of the colonies, smeared them onto microscope slides and examined them under the microscope
Results:
List of items from the MOST bacterial colonies to the LEAST (most disgusting to least disgusting)
- Bottom of dog paw
- Aquarium water
- Kindergartener's palm (yep. We are going to have a little talk.)
- Exterior of a worn medical mask
- Interior of a worn medical mask
- Laptop keyboard (at this point, these items #6-10 had very, very few colonies)
- Headphones
- Bottom of cat paw (ironically, one of the cleanest things on the list)
- Unused mask
- Inside of a toilet (yes, this was literally the cleanest thing on the list - which was shocking)
Some pictures of the bacteria under the microscope:
I'm assuming this is bacillus bacteria.
Close-up, this also looks like bacillus.
The picture didn't end up as clear as it looked through the microscope, but these looked like clusters of grapes. They were also much tinier than the bacillus bacteria. I'm wondering if they weren't cocci bacteria?
College Students
College freshman made an appointment for his TSI testing. He did a practice test for the math and only missed a couple of questions, so I think he feels better about it.
College sophomore is all ready for school on Monday. She is trying to buy a used camera for her photography class. They're supposed to develop their own film in the darkroom at the college. Her classes for the semester: Developmental Psychology, Intro to Speech Communications, Intro to Horticulture, Photography I, and Nutrition.
