Looking for the Aurora Borealis

How do you find the Aurora Borealis? Can you see it near your house?

It depends on many factors. Most of the time, the Aurora is visible only around the polar regions of our planet (and other planets for that matter).

However, when there are fluctuations in the Earth’s magnetic field, sometimes the Aurora Borealis can be seen further south.

I found this website which shows where the Borealis is visible during different periods of activity. Check it out.

Here’s a gallery of recent photos since the Northern Lights have gone a bit further south, on Flickr. Beautiful photos.

Leave a message…did you see the Borealis near your house? I’d love to hear about it.

In Awe of the Aurora Borealis

The most beautiful shows on display in nature are the special feature known as the Northern Lights, or Aurora Borealis. If you live south of the equator, it’s known as the Aurora Australis, or Southern Lights.

The first time I ever saw the Northern Lights, I didn’t know what it was. I never heard it discussed in science class, nor had I ever heard too much about it. I had heard the name Northern Lights before, but wasn’t sure what it would look like or what to expect.

At the time, I was attending school up at Northern Michigan University, in Marquette, Michigan, where you could watch the Borealis dance across the skies over Lake Superior. The sight was quite breathtaking, to say the least, although my first sight of them made me a bit frightened and looking for cover. All I knew was that it was the mid 1980s, the cold war was on, and we were near a prime target military base. To me, it looked like a nuclear explosion. Sounds a little foolish now….I was young.

Thankfully my eccentric astronomy professor was nearby and explained to me what it was. He took the next day of class to explain the Borealis, since those of us who live more southernly had never seen it before.  I still stand in awe of the borealis.

I could only see a small flash of the Northern Lights near the northern horizon for the last couple of days, but that’s more than we normally see this far south. Still, it’s so beautiful, I’m in awe.

My Thoughts on Telescopes

Saturn from 1996 to 2000

After my post on Nature Study Supplies, Missy asked this question, and I think it’s a good one:

Can you post something or maybe even write more here in the comments about why you don’t like telescopes? A telescope was on our “wish list” and you have made me wonder if we should just not get it. Thanks.

When we only had two children, hubby and I both bought each other a telescope for Christmas. Not deliberately of course, but because we both think alike on these things. He saw a telescope on sale for a great price at Natural Wonders, and so did I, so we each secretly conspired with our Christmas money to buy them, and obviously one of them went back.

We soon found out something, living in the city at the time: City lights interfere with the telescope in a big, big way. You couldn’t really see much of anything because of the lights all around our neighborhood. We also had one little old lady (every neighborhood has one) call the cops on us for having a telescope “spying” on people. Um, yeah. In…the…sky….

So, naturally we were disappointed at the time,  but also excited when we moved up to a more rural area. Still, the lights were a little bit of a problem, but we were able to position the telescope behind our barn so that, although our view of the Southern sky was hindered slightly, we still were able to see quite a bit.

Except…there were a few other issues no one warned us about:

  1. If you even so much as breathe too heavily on your telescope while you are trying to look closely at an object in the sky, you may inadvertently and easily knock it out of your view with the slightest bump. As you might imagine, this makes it an exercise in extreme frustration for those of us with little kids.
  2. Objects in the sky move. Okay, we knew this already, but what I didn’t know was that although I can’t see it with the naked eye, after spending all that time lining up objects in the telescope, the object didn’t stay in our line of view with the telescope for too long.
  3. Focusing the telescope, depending on the telescope you have, takes great care and patience. You aren’t just going to say, “Okay, kids, lets go out and look at Jupiter!”, and then have it in your view within five minutes. It could take up to a half and hour or maybe even longer.
  4. What you see through the viewfinder of your telescope will look like photo bokeh at times or blurry lights…not like the photos you see on the Discovery channel or the Hubble Website. You’re using an amateur telescope, not Hubble.

Happy Birthday, Hubble

One of my favorite resource sites for science is the HubbleSite.org, which is the offical site of the Hubble Space Telescope. The photos, like the one above, are simply breathtaking, and leaves me reaffirming that the heavens really do declare the glory of God! What artistry!

Some of these photos which Hubble took could be great ideas for watercolor paintings or drawings.

Well, Hubble is now 20 years ald, so happy birthday to Hubble.

On the site this month, you can find some interesting resources, including a video about things that scientists have learned from Hubble and why it was important to have a telescope in space vs. earthbound, and a pdf file about the most important discoveries made by Hubble (both are on this page). Though I didn’t agree with some of their conclusions (the idea that the universe is billions of years old is based on the idea that the speed of light is constant and not relative as Einstein theorized, and unless we saw something come into existence, we can’t say “for sure” how old anything is), the kids and I found it very fascinating.

Something else we enjoy over at Hubble is their monthly feature “Tonight’s Sky” (now on the Amazing Space site) which will have you looking at the sky with more understanding, and learning different constellations and astronomical features. Do check it out! This month’s video also has a section on the summer solstice which your kids may enjoy.

We were sitting there, on the hood of the parked car, looking at the sunset. The colors were especially stunning last night, and we were just quietly watching the magnificent show, when my youngest asked me what made the colors all come up like that.

There was a brief memory of something I learned in Astronomy class about light refraction and blue filtering out because of particles or something…I couldn’t remember. Thank God for the Internet.

What follows is a very brief (and over simplified) answer, suitable for an elementary schooler who doesn’t care about physics just yet. There are literally thousands of other websites with far more detailed and technical answers available for you, for further study.

Basically light is made up of all of the colors of the rainbow (this is what causes rainbows…but more on that another time), and as it passes through the atmosphere, blue and violet light is filtered out first. So, in those areas where light has to travel the least distance, the sky tends to look more blue than in those parts of the world where, at that moment, the light has spent more time in the atmosphere, being filtered. In those parts of the world where the light has already passed through quite a bit of the atmosphere (in other words, those parts of the earth experiencing sunsets and, to some degree, sun rises at this moment) the sky will appear more reddish.

To help dear daughter understand the concept better, I drew her a diagram, which you may fine helpful (below).

Taking Time to Watch the Geese…and Draw Them!

Goose and Goslings by Kimberly Eddy

Sometimes I wonder what someone from the 19th century (or earlier) would think of our modern day claims of ” too busy” or “not enough time”. I am guilty of it too. I never seem to have enough time, despite having so many time saving conveniences available to me today.

One cure for feeling overly busy is to just take the time to stop, smell the roses, look at the geese…and then draw them.

The other day, we were super busy with a few errands, but my daughter was lamenting that we hadn’t been to a certain park in a while, where wild roses grow, and where beautiful geese are everywhere. I realized that part of why I have no time is because I need to make the time for some things, like going to the park. We got out of the car, a light rain was just starting (not enough to get us soaked, but enough to be refreshing on a hot day). The geese were out and walking around.

“Why are the geese out even when it’s raining?” my daughter asked.

“Hmmm. Why do you think? What are they doing?” I answered with a question. I wanted to see if she could figure it out.

“They’re eating. Oh! I know! The worms come out when it’s raining like this!”

“Right! Exactly.”

We watched them for a while, enjoying all of it. Then we went in the car once the rain picked up, and sketched them for a little bit.

Time well spent!

Why Nature Study?

Kids who spend time enjoying the out-of-doors experience many benefits

In an article I’ve quoted in a past post, by Adam Voiland entitled, Why Kids Need a Big Dose of Nature , Mr. Voiland interviews Richard Louv (author of the excellent book, “Last Child in the Woods”), about the today’s children and their lack of contact with the out-of-doors. Voiland asked Louv, ” In addition to preventing disease, is there evidence that exposure to nature can actually boost abilities?”, and Richard Louv responds:

“Much of the evidence points to benefits. We see increased self-confidence, better body image, and cognitive benefits. Kids who spend more time outdoors tend to do better on testing; they do better on science; they tend to play more cooperatively.”

I agree.

As I said in my other post, one of the biggest benefits to nature study is just being in nature, and the health benefits of being outside, enjoying creation. It can’t be underestimated. There are other benefits I’ve found to nature study too:

1. Nature Study Can Help With Attention

For one thing, being outside and starting to really observe the world around you helps you to better take a look at everything. You start to notice details you never noticed before. As a mom or a teacher, if we ask our children more pointed questions to get them looking closer at the natural world around them, they may start to notice these details on their own. Essentially, you start to train them to pay attention to details.

This eventually spills over into other subjects and diciplines. Attention to detail is a huge benefit in all subjects and endeavors.

2. Nature Study Provides a Practical, Hands-On Frame of Reference for Science

To read about the parts of a flower in a science textbook is one thing; to actually go outside, look at all different kinds of flowers, and try to identify the parts is another. You can learn about botany in a classroom or from a book all you want, but until you actually interact with nature, most of it will just be theory.

To put it another way, in the Bible, in the book of Proverbs, Solomon frequently refers to Wisdom, Understanding and Knowlege. A lot of us have Knowledge– that’s knowing facts. And facts are good. Understanding is when you can see how those facts fit together. You don’t just know the parts of a flower; you understand what they do and how they work together to form fruit and more seed. Wisdom however is being able to take what you know and understand, and apply in in practical ways. When a child (or adult) really grasps a concept, instead of just knowing facts about it, they have truly learned.

Hands on nature study provides a way to help make those lessons on the natural world stick in the minds of our children. It also will help our children to develop a love and respect for the world around them, helping them understand and care about conservation issues in a practical way.

3. Nature Study Provides Fresh Air and Exercise

By default, nature study requires some walking, some out-of-doors time, and a little bit of exercise while all of that learning is taking place, vs. spending time in front of a box. This is good for both health and emotional well being.

In fact, according to this article from the New York Times website, A Dose of Nature for Attenion Problems, a recent study points to simply being in nature as beneficial to those with attention deficit disorder. I know as someone who also has ADD as an adult, nothing clears my head and helps me focus quite like an afternoon outside. The author writes,

“A small study conducted at the University of Illinois at Urbana-Champaign looked at how the environment influenced a child’s concentration skills. The researchers evaluated 17 children with attention deficit hyperactivity disorder, who all took part in three 20-minute walks in a park, a residential neighborhood and a downtown area. After each walk, the children were given a standard test called Digit Span Backwards, in which a series of numbers are said aloud and the child recites them backwards. The test is a useful measure of attention and concentration because practice doesn’t improve the score. The order of the walks varied for all the children, and the tester wasn’t aware of which walk the child had just taken. The study, published online in the August The Journal of Attention Disorders, found that children were able to focus better after the “green” walks compared to walks in other settings.”

What benefits have YOU noticed when partaking in nature study?

Hooray for Imperfect Nature Sketching

June 10th, 2010

Right off the bat, there’s something you need to know. Nature sketching is not about drawing perfectly.

The whole point of the DVDs I’m doing is this: most kids (and adults) are afraid to sketch because they feel they aren’t “good enough” or “can’t do it”. Most of the time they don’t know where to start. That’s where my DVDs come in: I want to help them get a good starting point, and to know how to start drawing common flowers, plants, animals, and so forth in nature.

Wanting to pay attention to details or to do a good job is a commendable trait, unless it paralyzes us into doing nothing because we are unable to do things perfectly the first time. We need to break free, and help our children break free, from the variety of perfectionism that keeps us from trying new things. We need to run from the fear of failure that keeps us from venturing out of our comfort zones.

If you have a child like this (or if you are an adult like this, who is always afraid of “doing it wrong”, let me give you and them permission to scribble, make stick figures, and use crayons if you want. Your nature sketchbook doesn’t have to look as though it will be in a museum in 100 years. Your nature journal/sketchbook needs to reflect your experiences out of doors, things that have caught your eye, details you noticed. If you don’t want anyone else to see it: no biggie.

Like many other things in life, the more you sketch and journal, the better you tend to get at it, and the more comfortable you will be doing it.

Nature Study Supplies

A reader recent emailed me to ask:

I’m a little confused at to what I really need to do some nature study this summer with the kids. Is there anything in particular I need?

Short answer: no, just nature itself. A pair of comfortable walking shoes may also be a necessity (flip flops are a bad idea on a trail).

Now, there are some things that I’ve found to be helpful, but not really necessary.

You may find it generally helpful to have some kind of a back pack in which you can carry different things. We use a back pack as a picnic basket of sorts too, as we often have a picnic outside at the park or nature center when we go. In your knapsack, some things you may want to consider having on hand include:

Backpacking Indonesia

  • a small first aid kit (maybe just a few bandaids and neosporin)
  • bottled water
  • bug spray
  • sun screen (especially if you are fair skinned like me and my crew are!)
  • snacks
  • and any of the other items I’m mentioning below.

A camera is a great thing to bring along. As I’ve said before, you can’t always make nature sit still long enough to draw it (or draw it well) but a photograph can be used to sketch from later. In this day and age of many affordable digi cameras (with many good ones under $40– including one my daughter just saved up and bought by Vivitar), you may want to consider a digi camera to be a birthday or Christmas present coming up. With a digital camera, you no longer have the two expenses that made my parents not allow me to have a camera for years: film and picture development! If you are looking for a digital camera of good general use with your older children, make sure it has an SD card slot. The ones that don’t often result in lost photos.

A Magnifying Glass is pretty good to have around for looking more closely at bugs, flower parts, and so forth. These are usually not a lot of money at all (Under $10). Glass ones may break more easily but don’t scratch up as easily as plastic lenses. I keep ours wrapped in a towel in our bag.

Binoculars can also be helpful for seeing something a long distance away. A camera’s zoom also works pretty good if you don’t have binoculars, and you can actually take a photo of it while you’re looking. :-)

One thing I really don’t recommend: A telescope is more trouble than it’s worth. Unless you are a serious astronomer with lots of patience, you may be disappointed.

A set of field guides is also nice to have, so that you can look up those things you are seeing, to figure out what it is you are looking at. I’ve written more about field guides here.

Some basic sketching supplies are obviously important for keeping some kind of a nature sketchbook. I’ve written about basic sketching supplies here, and about choosing a sketchbook.
