Homeschool Day 1/10: Flower Dissection Lab

 Flower Dissection Lab

We had specimens from the following flowers: Euphorbia, Haworthia, Tropical Hibiscus, orange Bird of Paradise and Purple Heart Tradescantia.

We identified:

  • xylem
  • phloem
  • stamen
  • anthers
  • carpel
  • ovules
  • petals
  • receptacle
  • sepals
  • pedicel
  • pollen grains
We looked at the petals and pollen grains under the microscope.  It was a great dissection.





Tropical Hibiscus




Very clear dissection




Petal with pollen grains under the 3D microscope

Botany Lab: Plant Slides

 We looked at the difference between Monocot and Dicot stems under the microscope.  We also looked at Zea mays cells (corn), Ranunculus cells (buttercups) and onion cells.

Here are the Zea mays slides - this is a monocot, because the vascular bundles are not in a clear ring around the edge of the stem.  The vascular bundles are in a random arrangement.

Also, these pictures are terrible, because it is really hard to take a picture with your phone through the eyepiece of a microscope.

Slice of a root (corn)- Monocot



Slice of a stem (corn) - Monocot



Onion cells with clear cell walls and nuclei.  One cell is undergoing mitosis.


I didn't take pictures of the ranunculus, but I should have.  It was clearly a dicot, with a ring of vascular bundles around the edge of the stem, with a pith in the center.

PlantSnap - plant ID app

 I just downloaded PlantSnap, an app for plant identification.  Here's the link: https://www.plantsnap.com

The app was free.  I went outside and took a picture of a plant.  The app has you move the image and expand it into a box, then it tells you what the plant is.  It gave me the common name, scientific name, a description, some of its classification (kingdom, division) and then there are options to learn more about the plant from tutorials on PlantSnap's Youtube channel.  Near the description of the plant, you click on the three vertical dots, click "watch tutorials" and it takes you to the videos of that plant species.  

There is an option for a premium version.

Pond Culture - Two weeks later

UPDATE: After doing some online research, we've figured out that these are Infusoria.  They eat phytoplankton.  They love decaying plant matter and you can actually culture these (which we accidentally did).

Two weeks ago, the 14 year-old and I collected pond water samples from a local pond.  When we looked through the microscope the same day the water was collected, there were a few protists on the slide.  We placed the remaining water sample into a jar with decaying plant matter.  The water sat unattended for two weeks.  

Today, we made new slides of the water to see if anything has changed.  There was a dramatic increase in microscopic life.  Here are a couple of videos of what we saw under the microscope.

Homeschool Day 4/13

 Kindergartener

  • Listened to me read aloud The Wonderful Wizard of Oz.  This was originally supposed to be for the 13 year-old, but he listened quietly to the entire second chapter, so I guess I'll invite him in to listen when I read it again tomorrow
  • Played in the woods, skipped rocks in a creek, played on the playground
  • Went with me to run errands
13 Year-old

Homeschool Day 3/29

 Five more weeks left of this "semester" - even thought we school year-round and it really doesn't matter.  But, I have been keeping track.

Kindergartener

  • Summer's Lab science - what is living and what is non-living (kinda obvious, right?).  This led to a discussion of cells, looking at onion cells under a microscope, looking at a model of a cell and watching an animation of the inner life of a cell.  This is actually a fun video - made by Harvard.    https://www.youtube.com/watch?v=B_zD3NxSsD8  We also watched a video of bacteriophages attacking an E. coli bacteria.  (He's really interested in cells for some reason)
  • We read I Am a Booger: Treat Me With Respect - yes, it was gross
  • We read Far North in the Arctic: Counting Alaska's Animals
  • I Spy! Extreme Challenger - we did one of the challenges
  • Ballet class today
13 Year-old
  • Gospel of John
  • Algebra video
  • Language Lessons for the Secondary Child
  • Free reading
  • She read To Kill a Mockingbird, I read Mrs. Frisby and the Rats of NIMH
  • History video: "WWI: The Aftermath"
  • I'm going to try to find All Quiet on the Western Front tonight on streaming
  • Anatomy reading
  • Ballet class today

Our cat sleeping on To Kill a Mockingbird.  Maybe the title of the book was interesting to her.



16 Year-old
  • 2 Samuel
  • Algebra 2 video
  • Also Ballet Class
  • Language Lessons for the High School Student
  • History video: "WWI: The Aftermath"
  • She'll also watch All Quiet on the Western Front if I can find it tonight

    • Researched Cotton Mather and write a short narration about who he was
    • Read "The Witches of Salem" from The New Yorker
    • Whatever Happened to Justice
    • The Fallacy Detective
  • Apologia Biology: Crayfish Dissection lab.  We followed along with this video during the dissection:  https://www.youtube.com/watch?v=oQ79ivCgNe8

This was probably one of the more disgusting dissections.  Its leg and claw popped off right away and the smell lingered around for several hours.  We were able to find everything in the dissection video, though.  A success!

Homeschool Day 3/17

 Kindergartener

  • eh...he skipped school today.  He went to Home Depot and looked at plants and played all day.
13 Year-old
  • Gospel of John
  • Algebra workbook page
  • Language Lessons for the Secondary Child
  • Free reading from her book crate.  She finished A Treasury of Poetry for Young People
  • She read To Kill a Mockingbird, I read Mrs. Frisby
  • She also went to Home Depot, which meant we didn't do more than we would've
16 Year-old
  • 2 Samuel
  • Algebra workbook
  • Language Lessons for the Secondary Child
  • Health - reading
  • Scarlet Letter Unit Study
    • Read The Scarlet Letter
    • Whatever Happened to Justice?
    • The Fallacy Detective
  • Apologia Biology - Earthworm Dissection. Boy, this was disgusting.  Surprisingly, we were able to identify the organs, including the ganglia.  I didn't think we would be able to, but our worm dissection abilities exceeded our expectations!  Yuck!

We ordered this earthworm from Home Science Tools.  It was huge and she didn't want to touch it.


Probably much easier to see in real life and not on a computer screen, but we were able to find all of its organs.  Dissection pins are an absolute must when you do dissection labs!  They really help.

Homeschool Day 1/21

 Kindergartener

  • Math workbook page
  • Handwriting without Tears - one workbook page + working with the capital letter chalkboard
  • Read a story from the Reader - All About Reading
  • Played Playdough
Five in a Row - Mirette on a High Wire

We went through the art sections in the teacher's guide.  We also got out some watercolor paints and paper.  We made a color wheel with complementary colors - paired blue/orange, red/green, and purple/yellow. 

13 Year-old
  •  Watched an algebra lesson
  • Language Lessons for the Secondary Child
  • Worked on spelling the books of the Old Testament
  • Free reading from her book crate and I read aloud
  • Apologia's Anatomy & Physiology - still reading about skeletal muscles.  I came to a realization today that she is getting more information from this middle school anatomy text than the high school sophomore is getting from her high school level Health course (ACE).  I've already been beefing up her labs with high school level labs to accompany the textbook.  She participated in several of the high schooler's biology labs at this point already.  If I can add a unit on First Aid/CPR, I'm planning to give her a half credit in Health.  She's literally covering the exact same material as the high school health course, but in better detail.  Because she wants to be a dentist, I plan to go through Apologia's Human Anatomy course anyway in a few years.
  • Ballet class
15 Year-old
  • Algebra 2 - we have reached a point where there are only a couple of lessons left of solving algebraic equations.  I'm now having trouble solving them.  I completely forgot about the Quadratic Formula.  I'm trying to remind her that there's light at the end of the tunnel.  After this unit is measurements and more graphing.  Then, on to Precalculus.
  • Wordsmith Craftsman - I'm dropping this after this week - this isn't working out
  • Huckleberry Finn
  • Narrative of the Life of Frederick Douglass
  • German together
  • Music Appreciation - last week, she asked, "What's bluegrass??"  Well, you're going to find out!  She listened to Earl Scruggs and Friends 'Foggy Mountain Breakdown' - a famous bluegrass song used in car chase scenes in old movies
  • Apologia Biology - lab 3.2
  • Ballet class
LAB 3.2

This lab entailed viewing different slides of protists under the microscope.  These are slides you can buy as part of a kit through Home Science Tools.  The protists are dyed, so you can see them more clearly.  Here's some examples of what we could see in our microscope:

Paramecium




Volvox
From my understanding, the circles that look like lily pads are the individual cells.  They group themselves together in colonies - which is what the pink bag-like thing is that's surrounding them.





We saw this under the microscope - it looks like the colony broke apart.



I love Apologia Biology and basically anything from Home Science Tools.  This is the third time I've taught this course and I really enjoy all the labs.

Homeschool Day 1/15

 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)
  1. Bottom of dog paw
  2. Aquarium water
  3. Kindergartener's palm (yep.  We are going to have a little talk.)
  4. Exterior of a worn medical mask
  5. Interior of a worn medical mask
  6. Laptop keyboard (at this point, these items #6-10  had very, very few colonies)
  7. Headphones
  8. Bottom of cat paw (ironically, one of the cleanest things on the list)
  9. Unused mask
  10. 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.




Homeschool Day 7/30

We will probably take next week off from school, since we are preparing for our daughter's wedding.  Also, we're almost halfway thro...
