The Real Scientific Method

Charlotte Mason said, “out-of-door nature-study lays the foundation for science.” (3/281) But have you ever wondered how that works?

To explain, I must start by clearing up a scientific myth — the ‘scientific method’ that you learned in school is ordinarily not used by scientists at all. The multi-step list seems to have started innocently enough when in 1945 a man named Keeslar prepared a paper with a list of things associated with scientific research. He submitted the list to research scientists and the items that were highly ranked were put in a logical order and made part of a final list of elements associated with the investigation of scientific problems. Textbook writers adopted this list as the description of how science is done and the “scientific method” was born. But scientists don’t usually conduct their research in the order outlined in the scientific method. They sometimes use it as an outline to write up their findings, but some people even take offense to this practice. (McComas) 

The scientific method then is a disjointed group of things a scientist does, just as a textbook is a somewhat disjointed list of things a student should learn in a particular field of science. Neither takes into account the natural way people learn or make discoveries in science. Charlotte Mason, on the other hand, always took into account the natural way people learn. She had an intuitive sense of the way a child would best learn a subject, but more importantly,  the way a child would best come to care about a subject. Continue reading

To Use the Scientific Method is Natural

 One of my children began reading a Christian Liberty Nature Reader this week.  So far I highly recommend this for early readers. One of the difficulties with a Charlotte Mason education is the necessity of finding very good beginning readers.  Our children have been hearing such high quality books from such an early age, so early readers have the potential to bore them. Thankfully there are good readers available, and it turns out that this is one of the gems. An added bonus is that it has a nature study focus.

The first chapter told how a mother Mud Wasps set up each of her eggs in a walled in nest. She puts several spiders within the nest, so the baby will have food when it hatches.  In the book there is a little sketched picture of the nest that really isn’t very clear, but my daughter found the description very interesting.

The morning following this first reading, she and I ran an errand, and out of the blue she made this sound of awe and disbelief.  I had missed whatever she saw, and had to wait until she could gather herself to explain. She spoke with amazement in her voice. “I can’t believe it.  I just saw it. There was a Mud Wasp nest on the wall in that tunnel. Will you go back?” I wish you could have heard the awe in her tone. It was like it was a gift set out just for her.  Of course, I went back and there is was. Just like she said.  I’m not sure I would have known what I was looking at, after all, the sketch had not been all that clear, but she could tell.

Once we returned home she looked up images of Mud Wasps nest, and sure enough, that is exactly what it was.

Now comes the good part. Sure, that was a pretty good part, but this is the science-y-blog good part.  After making these observations, she began asking questions: How does that mother Mud Wasp catch those spiders without getting stuck in the web? Does she have some kind of oil on her feet so she doesn’t stick, or does she swoop in like a helicopter, but not actually land? How does she collect several spiders and wall them in without them getting away? There were holes in those nests – is that from the baby wasps getting out? Are they little when they are born?

That right there is what we call the formulation of a question. (Well, several questions!)

A little later she said, “She might sting them, the spiders.” And another child said, “To paralyze them maybe.”

And there’s a hypothesis!

I was so good, (if I do say so myself,) because I casually responded by saying, “That’s a good hypothesis.” It’s so great when we can slip in correct terminology. Unfortunately, it requires knowing the correct terminology, and it’s better to say nothing than say the wrong thing, but I think I pulled it off this time.

So far there has been no testing or analysis, but just give it time!

I’ve been thinking lately that we really do a lot more experimenting than we realize, and if we are naturally experimenting, we are likely naturally using the scientific method.

To Experiment is Natural

Recently I purchased some grass-fed beef gelatin to make homemade jello. A friend told me that the best way to sweeten it is to use pineapple.  I thought pineapple was a no-no when making jello, but she was certain that it works great.  I gave it a try, and guess what – it didn’t set up. (It was yummy incorporated into a smoothy however!)

This made us ask why it didn’t work, or more precisely, why it did work for my friend. It turned out that the key was to use canned pineapple, instead of the fresh pineapple we had used. Canned pineapple is heated, which inactivates the enzymes that will prevent the jello from setting up. We read more about what precisely is happening when we make jello, and how fresh pineapple inhibits that. (If you are interested you can read more about it at chemistry.about.com)

Once we knew a little more, we tried again. We used the rest of the same fresh pineapple, but this time we heated it to 158°F first.  Good news! It worked great and we enjoyed a great dessert!

I share all of this because I’ve been thinking that we really do a lot more experimenting at home than we realize. We think that if we have not pulled out a book of chemistry experiments for young people, then we aren’t doing it right, but I would like to suggest that the opposite is true.

The first step in using the Scientific Method is to formulate a question. How better to start this process than to actually HAVE a question that you want to answer? When we open our book of experiments, we don’t have a question, we are just looking for an activity.

Start paying attention to the questions that arise while you cook with your children, clean, do nature study, play, whatever. Then notice how those questions get resolved.  Did anyone do any brainstorming or research that cause them to come up with a theory? (A hypothesis.) Did they do anything to test that theory? (An experiment.)  Did that confirm their theory or send them back to the drawing board? (Analysis.)

If you aren’t seeing this happen in your home, maybe it’s just because you’re not watching for it. It’s not necessary that you notice, but it might encourage you. However, if it really isn’t happening around your house, you may need to prompt things somewhere along the way. For instance, if you see that your child is left with a lot of questions, but never looks to find an answer, you might prompt him to research things he is interested in. If you see him looking for answers, but then always taking the “expert’s” word for it, maybe you should challenge him to test out these theories on his own to see if he gets the same results.

One last note. Please don’t take what I’m suggesting to the extreme and zap the fun right out of the adventure by forcing the process. This should be fun, inspiring, life.  Not another thing to check off their list.
