Botany Cabinet: Focus on the Essentials

An excerpt from the elementary biology album that reminds us why we use generic shapes in the botany cabinet, as opposed to leaf names specific to a particular region:


Once the child gathers a large body of knowledge from sensorial exploration, she can then begin to order and classify it.
An example of how this happens is by giving the child the name of the new shape rather than just giving the name of the plant from which the leaf comes. For example, the child can see that this plant has obovate leaves and so does this plant. That plant over there has sagittate leaves. When you give the name of the leaf shape, you give the children a tool to classify leaves and plants alike. Just giving the names of the plants, does not provide a basis for ordering and classification. This base of information is also built up through the use of nomenclature material in the primary. The nomenclature material is used by children who are reading and also those children who are not yet reading. Through the use of the nomenclature material, children learn the names of plants, parts of plants, names of animals and names of parts of animals. Eventually, all of this information can be ordered and classified. Another source for building up the child’s store of information comes from the stories, the poems and the songs that the teacher introduces about plants and animals.
All of this work becomes a foundation from which the children will launch with her work in the elementary.

Botany Studies: Herbal Remedy Kit

Just a quick post to show how much we LOVE our Herbal Remedy Kit from LearningHerbs.com.

LearningHerbs.com - Browse their website - they offer SO much more! (and so much is FREE!)
I think this was actually making elderberry gummies
(not included in the kit,
but the elderberries are!
And the recipe is easy-easy-easy -
we added some extras for specific ailments)
The Herbal Kit - price ranges from $67-97 with various promotions. WORTH - EVERY - PENNY.
In fact, after you have the kit and you get started - just getting your hands into it, you'll find that you can buy replacements or change things up through purchasing items from Mountain Rose Herbs (or elsewhere, but we love Mountain Rose Herbs too!).... and we do that! BUT we decided to buy a second kit too!

The kit includes step by step EASY instructions. Nothing fancy; nothing complicated. So don't let my out of order photos here scare you! Legoboy could do all of these himself - in fact, he does done much of it all by himself, when modifying or re-making some items later. He has been doing so since he was 9 years old. :)



We have now made everything in the kit - including the elderberry syrup which works SO great for the flu virus! (the FDA does not approve of that statement, just as a disclaimer - even though there are scientific studies done that strongly show the affect of eldererry syrup on flu strains)

By the by - when it comes to flu.... I had those dried elderberries for almost 2 years. Every time I'd open that cupboard, I'd think, "What is that smell?" It wasn't *bad*, it just wasn't a yummy kind of berry smell either. Well, the day after we fully moved into our house (the apartment was empty but still needed a final cleaning), I opened the new cupboard that housed the elderberries, and thought, "Oh, THAT smells SO GOOD!" When I realized what it was, I realized, "I am sick." Our bodies do tend to crave what they need, until we train them otherwise. And I'd been ignoring all the signs of being sick (blaming it on the stress of moving, the all-day training I'd done that Friday, then doing the final moving of stuff in the rain at the end of a long day, coming into the house (where carpet people were supposed to be GONE already) to find broken dishes in the sink and broken glass all over the floor --- apparently the pounding from above had shaken loose a light fixture, hitting the sink and shattering everywhere, I blamed my feelings on "that time of the month", and my son's own moodiness (oh wait - he was sick too!!!). Talk about ignoring all the signs!!!!

Elderberry syrup though. YUM. And when my body didn't need it anymore, it didn't taste so good anymore. Still good, but not something that I was craving. Same with Legoboy. He really noticed the change in desire for it as he got better.

The best part of doing all this learning together? He could take care of me when I was sick and I could take care of him - no worries!

The pictures below start with the second kit; then move to the first kit. In no particular order. I will try to identify what is going on in each picture, but this is not a narrative so much as a demonstration of what could be done with an herbal remedy kit!



Full contents before unpacking anything.
That white spot is a wrapped up bottle of Lavendar essential oil.
Chunks of beeswax
All the jars, bottles eyedroppers, and tins needed for this particular kit.
Dried herbs (see below)
DVD instructions (with online access and some printed instructions)






First Kit:

stinging nettle sitting in place to make an infusion (all the goodness goes into the water,
then you strain out the physical herbs and drink the infusion - highly nutritious - and EASY)

strained herbs - these can go into the compost or be used other ways, depending on the herb mixture

This is maybe the stinging nettle infusion - the top part looks right,
but the liquid looks the wrong color.
So it might still be the herbal healving salve
herbs when being strained. 

the completed herbal healing salve
once you know how to make one kind, you can make ANY
getting supplies ready for making the salve

further straining the herbs that had been extracted into warm olive oil
just the liquid/oil is then added back to the pan with the beeswax
The bag helps to squeeze all the rest of the goodies out of the herbs. 

the herbal healing salve setting up - just poured into the jars
warm is darker and more liquidy yet
the solid parts are cooler and lighter in color

just a pretty picture of the lavendar essential oil, the olive oil and the tin tops

the salve while setting up - some was still warm (darker)

the pretty box the herbal remedy kit comes in ;)

Vermi-Composting Part 2 - Building the new Bins

The worms are doing quite well! 

One little friend in the corner. 

Another from the other side. 

What caption would fit here? 

With the drill bit, he could do 3 at a time, so he stacked a 4th underneath
to ensure he didn't into the material below. 

He acts like he doesn't want to drill. So I said, "Oh just plug it in!"
"Just line it up here."
"Just squeeze the power button."

Amazing how powerful the word "just" can be ;) 

In the meantime, I was tracing, cutting and sanding 2 inch wide
strips for the frames to hold plastic sheets over the basement windows. 

Working totally independently now. 

Pretending to sand the rough edges (and tunnels from the melted portions!)

Authentic sanding

Bin #1 (the original - transferred into the new deeper, now drilled bin)
The bottom bin received no holes so it can catch the worm tea. 

The second one - a deeper bin with the drilled holes
placed in the original bin to catch the worm tea.
I moved about half the worms to this one. 

The second one I made more full by adding the rest of our fruit/veggies scraps that has been sitting in our garage and some soil from a dead plant and some more dry stuff. This one I will leave sit, removing the lid each day for a time, until it is almost fully composted; then we'll place the next bin on top of it (placing the lid on top of the new bin) so the worms can crawl up through the bottom holes, leaving the completed compost behind. When the worms are fully migrated, we'll take that finished bin out of the stack and use the compost!

Everything I read talks about that worm tea. And all the good worm compost bins I could have paid $65 or more for include a spigot in the bottom portion to drain the tea. I wonder how LONG it takes to get any?


I caught him peeking in on the worms earlier today - he claims he thinks they are creepy now that we have them and he throws a dramatic "AAAH!!!!" every time he sees them and I am around. Without an audience though? Well, I'll see if I can catch him in the act!

Biology: Vermi-composting

Yep. Counts for school ;)

Vermi-Composting

Composting. With worms.
Montessori elementary practical life in action.
or is it biology?
or geography?
Actually - practical life at the elementary level is integrated into every subject. 


The container just to get started.
Our real bins arrive soon. 
Our "real bins" are still going to be homemade; I simply can't justify spending $65 on the cheapest variety; $120 on the one I really want... And Legoboy approved (actually he was the one who balked at the price first!). So we have bins coming about twice the size of the above (6 of them for $30) - drill holes in the bottoms; the bottom bin will be placed inside a tub we already have, for liquid (worm tea) to drain from it; then we start filling the bottom bin; as it gets pretty full, we place the next bin on top of it with some scrumptious yummies for the wormies - they crawl upward through the holes (the bottom of the top bin rests on the top of the compost below) as they have less food below and more options above. As that one fills, we add another bin. Eventually, the bottom one is pretty much worm-free (doesn't have to be perfect) - and we have perfect compost for both indoor plants and our outdoor garden.
(WE HAVE AN OUTDOOR GARDEN!!!)

Just have to lift the bins and remove the bottom one. The liquid we have a hose set up to suck up the "worm tea" which is also good for enriching the soil around plants.

Awesomeness.

I was looking for a drawer system - so we could move drawers around and not deal with lifting out bins -- but I couldn't find one I liked. I sent Legoboy on a mission to find one and he came up empty too. Some close calls, but we both really like the systems where *we* don't move the worms - the worms transport themselves, so the next bin up needs to touch the compost below...

(if anyone has ideas, please share!!!)

Here is one little guy!  

We ordered a 250-count bag. Comes with the worms and some soil.
Our mailman placed these on our front porch in 32 degree temps. 

Yep. SOMETHING told me I better stop at home between dropping off Legoboy to tae-kwon-do and going to the atrium. Sure enough, a small white priority mail box was sitting on my freezing porch. 

It looks like they are no worse for the wear! 

Less than 12 hours - they've made some nice tunnels!
How did we know how many to order? Recommendations seem all over the place - and it does depend on the size of your bins. In the end, Legoboy decided we should go with one person's recommendation which really seemed to hit home: buy the smaller amounts and the worms will adjust to their environment. Everything we read agrees that the worms WILL adjust - they will not lay eggs if there is not enough food; but they will lay more eggs when there is more food and more space. They naturally balanced themselves out --- so why buy more that might die, when we can spend less money and let them "be fertile and multiply" - even if it is worms, let's create life instead of intend to destroy it. 

Cool. Then he has his joke below. Sigh. 

Legoboy is ok with the worms; but when it came time to actually look at them? 

"Ewwww! I am STAYing OUT of the kitchen!" (where we have the bin sitting for now - it will be moved to our basement once I get the windows better insulated.)


Today's reaction? Well, I will post all of the video attempts - none of which correspond to yesterday's reaction - and all of which highlight his goofy personality ;) 













I guess we count this as a preparation for adolescence. Learning those individual skills now (in elementary) that will be useful then. 

It is creeping closer and closer..... 



Exercises of Practical Life at the elementary level should be integrated into all areas of life and study. Children participate in Goings Out, so need lessons on finding their way on a map, planning bus or vehicle driving routes, exploring options for other forms of transportations, making phone calls to inquire about available products or set up an interview, interviewing skills, and the list goes on - just for Goings Out.

This leaves me yet pondering primary level practical life - if elementary practical life is SO practical, why DO we decide to get into the froo-froo stuff at primary? We tong-transfer pom-poms to the tops of golf tees to help with fine motor skills, but what else? It's just not *practical* - and there are SO MANY *real* practical life activities we can incorporate to practice those fine motor skills AND build skills in other areas.

Every primary (3-6) Montessori material might be intended to have one direct aim- one main purpose - but the indirect aims for some of the materials are almost endless! They are just that deep.

So let's keep up the standard! Real practical life in primary; moving into real (and integrated) practical life in elementary; leading into continued real practical life in adolescence and beyond!

Biology: Health and Dissections


One of Legoboy's August plans is to finish his study of human anatomy health (or come close to finishing). 

He selected the book "My Temple of the Holy Spirit" as his core resource, with "Blood and Guts" for follow-up. He is also using two anatomy "coloring books" (high school level) to read and color in as he learns about each area of the body. 

We added a couple of books on the development of unborn children to cover reproduction. 


This past week, he has been studying the brain, the sense organs and circulation as interest and focus strikes him. This morning (of the day I write this), he and I had a conversation about these topics, as something of an oral exam. He had his choice of styles of presentation of information to me: write about each area, create something in the area to show what he has learned, chat with me about it, or pick another adult with whom to chat. He chose chatting with Mama ;) Can't complain there! ;) 


As part of the brain topic, we looked at a model we had on hand; he identified the parts and function of what he knew and we looked up the rest. 

Repeated for the heart. We just happened to have both of these on hand. Not planned what-so-ever. 


But then he said, "Didn't we purchase a cow's eye from Home Science Tools?"

Why yes, Son, yes we did. 


Removing some of the fat. 

Removing the cornea

beyond the instructions:
let's cut in half laterally!
He wanted to see the layers behind the eyeball

there they are

any one more, just in case you wanted to see it again ;)
