do experiment #5 "Will It Tip?"

do experiment #6 "It's Sinking In"



discuss:
is there an amount of weight that we could put on the living room floor where it would bend or shift? yes, if a huge amount of weight was put on top of the space between the floor joists!

walk barefoot along the upstairs hallway and feel the place where the floor noticably curves underfoot; go into the crawlspace to see the floor joists below the living room floor


explain the Four Components of Productive Soil

note that on a build site, before the foundation is poured, construction equipment will very carefully remove the topsoil in order to get down to the subsoil (the loose fluffy soil that farmers want is the exact opposite of the tightly compacted soil that builders want!)

Updated Notes:

We finally mastered Experiment 3!

In my notes from last time, you can see how much we struggled with the setup of this experiment. This time we used bamboo skewers and the little balls from a Zometool set. For the Tuesday group, I had us put the white balls into the soil. But we weren't able to get more than one book to stay.

The skewers twist dramatically when they fall, which helps the children to see why the stadium collapsed both outward and inward as it fell down.

Then a student in the Wednesday group finally figured out the secret!

The flat end of the skewer goes into the potting soil, and the pointed end (with the Zome ball) sticks up! The balls spread out the force from the pile of books. And she really stuck with it, determined to balance all the books...

Hooray!

Number Bases in Montessori: Binary Mat & Octal Mat

My oldest student started the year with an exploration of Number Bases (Jamie York suggests doing this in Waldorf in grade 8; I didn't learn it until my math teacher training at Smith). We focused on Binary and Octal.

The Number Bases page on my website gives a number of resources; here, I want to focus on the new Montessori-inspired Not-Golden Mats we made for the classroom! The original Golden Mat material looks like this:

It is base-10, and it uses a set of Colored Bead Material that goes up to 9 (the highest possible digit in any place value).

With base-2, the mat would be green (the Montessori color coding for two). The only beads you would use would be the 1-bars. This is because 1 is the highest possible digit in any place value in the binary system. The place value headings across the top of the mat would also be different:

BINARY

n⁰ = 1
n¹ = 2
n² = 4
n³ = 8
n⁴ = 16
n⁵ = 32
n⁶ = 64

and so on, multiplying the value of the column by 2 each time

Figuring these out is a wonderful exercise for the childen, and we were very pleased with the resulting felt mat.

In a traditional classroom setting, it would be very easy for each student to make their own Binary Mat using a sheet of large green construction paper. Simply place a bead in a section to show a 1; an empty section is a 0.

It's fun to see all the zeroes and ones change as you count up from 1 to 20!

We also made an octal mat, which was super helpful for Jamie's Number Bases Practice Sheet #2 (PDF sample from Jamie's grade 8 workbook ).

Note: It works out really well for base-8 to read Weslandia by Paul Fleischman first!

For base-8, the mat would then logically be made of a dark brown felt, and we removed the extra bead bars from my Decanomial Bead Bar Box so that we didn't have anything higher than 7. Here are the place value headings:

OCTAL

n⁰ = 1
n¹ = 8
n² = 64
n³ = 512
n⁴ = 4,096
n⁵ = 32,768
n⁶ = 262,144

In my experience, it works best to use the Multi-Base Bead Frame when converting from decimal to the other number base (base-2 to base-16) and the Not-Golden Mats when converting from another number base to decimal.

For example, 37_oct would be represented by a 3-bar in the 8s place and a 7-bar in the 1s place. 3 x 8 is 24, and 24 + 7 is 31_dec.

Oops, One More... Tree Bingo

Yesterday I finished my Botany Books post and was feeling all proud of myself. Then, walking down the hall at the end of the day to close the door of the Board Games closet, my eye fell upon Laurence King's Tree Bingo.
I pulled out the box, and what do you think was on the front?? Date Palm!

What's in My Botany Books

First, I would like to update everyone that I'm no longer an Amazon Affiliate.

I cancelled my entire Amazon account last night after seeing news items about their invasive "About You" page and the new glasses their delivery drivers will be wearing to take constant photos of the path to your front door (that you cannot opt out of) which they can then use to train their humanoid delivery robots. This means that while in the past I spent a lot of time tracking down Amazon links to the specific books I was recommending, I will no longer be supplying links to purchase materials. I get most of my curriculum things used on eBay anyway, but Amazon was so pervasive that I felt those links were actually helpful to people. Now that so many people are boycotting Amazon, there's no reason for me to take the time.

End rant.

Instead of using a prepared Botany curriculum with a specifically laid out scope & sequence, we are just doing plants as they come onto our radar. They drop nuts, bear fruit, change colors, open flowers, give us a rash, etc. And we want to learn about them!

This means I need to look at my Botany books in a new light, and simply note which plants are covered in each. When we choose a plant, I can go to this blog post and hit "Find" to see if I have any resources for it.

"Tommy's Insect Soup" - pitcher plant

I also wrote up a 2023 blog post detailing the Bloodthirsty Plants series.

Animal and Plant Anatomy
11 volume encyclopedia

vol. 1 - apple tree

vol. 2 - diatom, fern

vol. 4 - hawkmoth, honeybee

vol. 6 - marsh grass, mushroom, orchid

vol. 7 - potato

vol. 8 - saguaro cactus, seaweed, sequoia

vol. 10 - Venus flytrap, weevil

Diatoms and mushrooms are not plants, but we may end up talking about them and why they are not plants, so I want to remember that they're included. The hawkmoth and honeybee are pollinators; the weevil is a pest.
