Molten….toothpaste?

I’ve mentioned time and time again that the hands-on experiments we use in our homeschool classroom are what helps connect information and really solidify a concept. The more we homeschool, the more I realize I’m learning right along with Jeffrey.

When learning about magma, we talked about how new landmasses are formed by volcanic activity and that magma not only forms earth, but also moves the earth that is there, changing and re-shaping it as it flows through.

While the ideal way of learning this concept would be to visit someplace like Hawaii or Iceland, where volcanoes reign supreme, we figured we could get the picture at home with some easy household objects: some dirt, some toothpaste, and an empty yogurt cup.

Any size or shape will work fine for the experiment. We went with what we had on hand… Yoplait.

Using scissors, cut a hole in the base of the cup, about enough to fit the toothpaste tube’s tip in, without having it any larger than that.

Then, stick the tip of the tube through the hole, so you can see the tip going into the cup.

Just like this!

Fill the cup with dirt. There, now you have your earth’s crust.

Now start squeezing. Hypothesize… what do you think will happen?

Remember, the toothpaste represents the magma, the dirt represents the earth’s crust, and the cup is just a good container to help hold it in.

As you squeeze, the magma will raise and move the earth, which is one way mountains and islands are formed and shaped. Then, some magma will actually begin seeping through as the crust cracks and moves.

I love when a relatively simple, easy-to-assemble experiment can really show exactly how something works. To me, it is invaluable to not only read about it, but to physically, tangibly see how it works. Now, go grab your toothpaste and try it out!

Permanently Frozen

In Kansas, sometimes it seems that the frost will never go away. It seems like, when it’s still snowing in May, the ground will stay hard, and the moisture will never sink into the ground. But then, just days later, we end up getting sunny, stellar weather, and the hard ground softens with warmth and rain, the temperatures getting back to normal.

There are many parts of the world where this isn’t the case, though! In Siberia, for example, there is a thing called “Permafrost,” where the ground never fully unfreezes. Even though the top of the ground will soften during the warmer seasons, deep down, it stays frozen, hard, and impossible to soak or build down through. When we were studying Russia, we encountered this fact, but we never fully understood how this would affect life.

Luckily, we encountered this great experiment in our My Father’s World curriculum that gave us a better visual representation of what permafrost looked like, and it used simple household materials: a bowl, Jell-O, dirt, and ice.

Start by making Jell-O! Any flavor will work, including the unflavored, but we just happened to have some Cherry Jell-O on hand. You’ll want to prepare it in a glass or otherwise clear bowl so you can see the effect it creates!

Once it’s set, it’s all ready to go!

Cover that perfectly good Jell-O with a layer of dessert (if you’re smart, unlike us, you’ll make a second set of Jell-O before getting to this step… because you’ll sit there craving it through the whole lesson!)

Once you’ve got a good couple of inches of dirt, you’ll want to top that with some ice!

Now that you’ve got the ice on there, you’ve got a fairly decent representation of Siberia. It’s time to sit back and wait.

You see, the Jell-O represents the permafrost. The dirt is, well, dirt. It represents the ground in Siberia. And finally, the ice is the frozen tundra, which will thaw and melt, and you’ll see how the permafrost affects it.

At first, from a side view, you’ll notice nothing is happening. There will be an ice layer, a dirt layer, and a permafrost layer.

As the ice melts (as though spring and summer are coming!), you’ll notice that the ground gets soggy…

…but the sogginess doesn’t permeate or soak into the Permafrost (Jell-O) layer at all!

Eventually, your ice will totally melt! Summer has arrived!

But look… it still never fully permeates the permafrost! There is always that layer there– meaning the ground will be very soggy.

So what does this mean for people who live in Siberia? For one, paths are really muddy! But the worst part is that muddy ground like that will obviously provide a very unstable surface to build on. It means that many of the older homes are uneven and sinking into the ground. Newer buildings must be built up on stilts that sink far into the ground, allowing them to stay sturdy and stable, so they don’t sink or fall into the ground. It can cause some major problems when you spend time dealing with all of the water on the surface or extra mud.

Permafrost is a difficult concept to figure out or explain sometimes, but this is a great, visual way to show how permafrost works, and the effects that it has on structures and surfaces in Siberia.

 

Dirt Won’t Hurt Them

I had another post planned for today, but yesterday, I saw my son explore something he’d never gotten to explore before, and it changed my mind on what to write about. I felt this topic was so important, weighing on my heart so much, that I really need to share it with you.

I remember a few years ago, before my son was born, when the Crayola colored bubbles first came out. I was excited about them. When it turned out that they stained, I was okay with that. You know what? That’s why we have some stained hand-me-downs. No big deal. Another mom and I got into a discussion, and at one point, it got fairly heated. She said that she was absolutely not okay with her children playing with things that would get them dirty; she went on to say that destroying clothing, even old ones, was a waste of resources, and it was a waste of energy to clean up after the mess. I always said I wouldn’t be “that mom.” When I was little, my mom frequently allowed me a roll in the mud. She firmly maintained the stance that both children and clothing were washable.

So, when the new Crayola colored bubbles were released (still staining, but not quite like the original), I bought them. And honestly, Zach loves them. The thing is, I can’t tell you how many times Zach has come to me with a new marker tattoo when the pen strayed off of the page. I can’t tell you how many bubble-and-sand hairdos we’ve had.

One particularly fond memory was an evening when I gave Zach some chocolate pudding. I handed him a spoon, and he started eating it, the same way he does with his yogurt. Suddenly, though, that spoon was not enough, and before I knew it, he had chocolate pudding all over. His face, his ear, his hair, it had pudding. Chocolate, smeary pudding.

As soon as I saw him, I shouted “Zach! What are you doing?” Then, I saw him look down, ashamed, and I thought… wait a second. It’s not getting on anything. (Well, except for Zach). So I opened up another pudding cup, and began eating it directly out of the cup. Before I knew it, I had pudding on my nose to match his.

So yesterday, when Zach and I were playing outside, and I noticed a large stream of water flowing through a muddy path in the backyard, instead of keeping him out… I opened the gate and said “Go for it.”

He splashed. He slid. He used it kind of as a slip-n-slide. He went mud skating. He mushed it in his fingers. All of this is important. It’s a texture that he’s never felt before, a feeling he’s never experienced. And this was one more step in his learning process.

Sure. His clothing got muddy and wet. His hands were icky and mucky. If you look closely, you can even see some green marker from an incident earlier in the day.

As Zach grows, naturally, he will learn that there is a time for messy play and a time for clean play. Dressy clothes aren’t for mud pies, and mud pie clothes aren’t for church. But for now, these experiences mold and shape him. They make him who he is. They help him learn about different consistencies and textures, as well as the thought that dirt and water combine to create something that isn’t really dirt or water, but some sort of substance in between.

Obviously, as soon as his mud play was over, he went straight into a bath. And, within 30 minutes, you couldn’t even see a speck of evidence of the mud or the marker.

In some ways, I have to compare this to my journey in faith. I go through life. I sit there, and I get all of this muck, and filth, and dirt, and grime, and it’s everywhere. It’s in every nook and cranny, under my nails and between my toes. And I am gross. Disgusting. And then, I get this healing water, this Holy washing, basically, and I am made clean. I’m renewed. I’m a NEW creation in Christ. And all of that filth, that dirt, that grime, is gone. Washed down the drain, out of sight. Just like the mud on Zach’s skin. It’s just… gone.

I love that. I love when life provides me with a metaphor that helps me so clearly relate what happens in my life to what has happened to me spiritually, what is STILL happening to me spiritually. I still sin. And even then, God washes me and makes me new.

In the end, I really have no control, and no desire to have control, over whether or not another parent will let her kids play in the dirt and mud. In many ways, I kind of feel like they will anyway. Dirt, mud… it isn’t for everyone.

But as for me and my son, we’re going to be stocking up on a lot of stained clothing, colored bubbles, and pudding cups, because I see a LOT of messy days in our future.
