The Moon Unplugged? Not For Me!!

By Mom Unplugged, August 27, 2007 9:52 pm

My second grade daughter came home from school today positively vibrating with excitement at the prospect of viewing the total lunar eclipse tonight.

I should have been overjoyed by my child’s excitement at the chance to observe first-hand a scientific wonder, a miracle of nature, becoming one with the universe for the very first time, etc. etc. etc. I should also have mentally applauded her new teacher for managing to instill in my daughter this voracious hunger for learning more about our universe.

My real mental first response: “Huh? Doesn’t all that happen at night? When I am enjoying my blessed few hours of solitude, comfortably asleep in my warm bed? Doesn’t it happen outside…where it is, well…cold? WHAT WAS MR. N. THINKING???”

My next thought was: “Can’t we just watch it online in the morning? Plus it’ll go faster and we won’t have to sit there for the full three and a half hours. We can’t Tivo or time lapse the real thing, plus we’ll freeze to death and be tired and crabby. With a time lapse webcam we could see the whole three and a half hours in about 20 seconds…and still get our sleep!”

I am ashamed of myself. Mom Unplugged indeed. Lover of nature and the outdoors, devoted to my children’s education…and it actually occurred to me to watch this great natural spectacle online in fast forward!! Or maybe on YouTube, like this version of the total lunar eclipse that occurred back in March.

I have reached a three-part mental compromise:

1) There are three skylights over my bed. If I wake up in the night and see the moon through the skylights, I will get my daughter and we can watch from the warmth of my bed. (In other words…she will be educated while I sleep. What could be better?)

2) If the moon decides to be stubborn and not position itself conveniently over my bed for its eclipse, then I will conduct a scientific analysis of the apparent cloud cover mathematically combined with my state of alertness, and then decide whether or not to get up and search for that naughty, uncooperative moon. (In other words…I might get to sleep. Hey, it might even be too cloudy!)

3) I sleep through the whole thing and I will have earned myself yet another Mom of the Year Award (In other words…I get to sleep, but with a guilty conscience.)

Happy Birthday Sea Monkeys!

By Mom Unplugged, July 15, 2007 8:58 am

I am sure you have all been dying to know how our Sea Monkeys are doing. Well, they are just fine thank you! At left is a bad picture of their tank. The little beige things swimming around are the Sea Monkeys who are now about 1/4″ long from head to tail. They are just a little over one month-old! HAPPY BIRTHDAY LITTLE GUYS!!!

I am supposed to be packing for our big trip tomorrow but I hate packing and have found the ultimate form of procrastination: attempting to photograph a 1/4″ long, rapidly swimming Sea Monkey using only a mediocre digital camera.

After about 25 attempts, I finally got it just right and snapped a Sea Monkey portrait to be proud of!

Here it is:

Isn’t he cute? His name is Squiggles 7, or maybe Squiggles 23, I am not sure since they all have a very strong family resemblance.

To read about the process of hatching Sea Monkeys, see my June 18th, Perfect Pet post, or click on the label “sea monkeys” in the right sidebar.

Now, back to my packing. Big sigh. I will be away for about three weeks and will have computer access, although my posts might be a bit less frequent.

I advise everyone to stay off Southwest Airlines on Monday, as you risk meeting my screeching 18 month-old in person. I plan on passing out ear plugs.

Project: Make Your Yard a Certified Wildlife Habitat

By Mom Unplugged, July 5, 2007 11:10 am

A really neat project to get kids involved with nature (and help wildlife) is to certify your yard as a Wildlife Habitat. The National Wildlife Federation has a certification program that is fun to do with kids. So far there are over 70,000 certified backyard habitats.

You do not need a big, fancy yard to get certified. What you do need however, are four basic habitat elements: food, water, cover, and places to raise young. Click on the links to each element for examples, as well as projects for incorporating these elements into your yard.

Sit down with your kids and evaluate your yard. Decide together what you can do to make sure that the four elements are present. Create a plan and carry it out. When you are done, complete the online certification questionnaire.

If you are still lacking in any area, the website will tell you what you need to improve. If you have the basic elements, then you will get a certification number. You will also get a one-year membership to the National Wildlife Federation which includes a subscription to National Wildlife magazine. They will send you a certificate and a press-release for your local paper to help spread the word about this program. Plus, you can order ($25) a cool, weather-proof sign like mine in the photo to really let the world know about the importance of gardening for wildlife.

Here are some examples of each element from our yard:

Bird feeders are an obvious choice for FOOD. Include many different varieties of seeds (sunflower is the favorite here, but we also have millet, thistle, and cracked corn), suets, and a hummingbird feeder of sugar water. We put peanuts out for the squirrels and chipmunks too (although quite a few birds enjoy the peanuts as well). Also, diversify your feeder types. Some birds like perches, some prefer to cling, some like platform feeders like the one on the left. We also have a birdseed block on the ground for ground feeders.

Other, less obvious FOOD sources are native plants, bushes with berries, and flowers that produce dried seed heads such as these Purple Coneflowers:

If you aren’t fortunate enough to have a pond or other natural water source on your property, birdbaths are essential for providing WATER. This is one of our three bird baths. One of them is heated so water is available in the winter also. Even the squirrels drink out of them! This photo also shows a FOOD source: the Cosmos flowers around the birdbath produce nice seeds.

This birdbath is near a tree so drinking birds have an easy escape if necessary. Our birdseed block is in the foreground.


Examples of COVER in our yard:

 

PLACES TO RAISE YOUNG can be man made such as nest boxes or bird houses, or natural: trees, shrubs, dead trees. Even a woodpile, like our messy one above, provides great nesting opportunities for chipmunks and other small rodents.

We are fortunate enough to have this lightning damaged, partially dead tree (a “snag“) behind the house which, as you can see from the photo below, has become a bird condo! In fact there is a very noisy family of Lewis’ Woodpeckers currently nesting in one of those holes.

We hung some roosting pockets under the eaves (near a window so we could watch the action), but there have been no interested birds so far.


Here are some book suggestions to help you too. The Backyard Naturalistis a wonderful book and has helped me a lot, but you will only find it used.

This one is a great guide to native plant species in my region. Obviously, if you don’t have a high elevation western garden it won’t do for you. But check your library, bookstore, or Amazon for similar regional guides to get native plant ideas.

I don’t have this one, but I think I will order it. It looks like a really good one too, with lots of ideas for projects.

The National Wildlife Federation also has an online gardening bookstore that you might want to look at as well.

The Perfect Pet (?)

By Mom Unplugged, June 18, 2007 8:09 am

On International Sea Monkey Day (May 16th - mark your calender for next year) I revealed my secret fascination with the sea monkey concept. So, during one of my as-infrequent-as-possible trips to Walmart, how could I pass up the $6.00 Sea Monkey kit that I happened to see!

Despite my warnings that the “Sea Monkeys” (aka. brine shrimp) would definitely not be as cute and cuddly as the picture on the package, my kids were thrilled with this experiment.

It was really quite simple. First we had to fill the tank with tap water. Then we put in the powdery contents of packet Number 1, a water purifier, and let it sit 24 hours.

The next evening was the fun time. After insuring that the water was the recommended temperature, my daughter poured in Packet #2, the eggs! My son stirred, and voila!

The results? Well, not much that we could see. Perhaps our water was a little colder than recommended (means a longer hatching period).

By the next morning however, three almost microscopic little squiggles were visible (sort of). The children christened them Squiggles, Squirmy, and Wiggles. By that evening we had such a colony that naming them was impossible (how about Squiggles 1, Squiggles 2, Squiggles 3… Squiggles 142, etc.). Such excitement! You’d think we were hatching chickens or elephants or something.

On day 5 we gave them a bit of food from Packet #3. They seem pretty happy. I guess I don’t see why brine shrimp can’t be happy.

We have had them a week now and I must say they are growing rapidly. You can now make them out easily, and if you look closely, you can even see their little waving legs (arms? fins? cilia?). Still too small for a photo though, so I will post this dramatic closeup from Wikipedia:

Try this project with your kids. I would say that we have definitely had our $6.00 worth of fun already!

Plus, maybe they are not so cute, maybe they are not so cuddly but - they don’t yack up furballs on your new sisal rug, need a walk in the middle of the night or shed fur all over your favorite little black dress.

Kids Bored? Whack a Geode!

By Mom Unplugged, June 7, 2007 6:55 pm

My 6 year-old daughter is obsessed with rocks. I find rocks in her pockets, in her little purses, in jars on her desk, in her nightstand drawer, and once, even in her bed! She even likes to look at and read books about rocks. I list her favorites below.

We got started on geodes when one of her school book fair books came with a small, uncracked geode. She brought it to school on her “Sharing Day” and cracked it in front of her class, a performance which was, apparently, a big hit with her classmates.

In case you have never encountered one, a geode is a very unimpressive looking rock on the outside, as you can see here:

Geodes form in porous rocks such as limestone or lava. If a hollow cavity exists in the rock, water containing dissolved minerals can seep in through the rock’s pores and crystallize on the inside walls of the cavity. If the crystals do not completely fill the cavity, then a geode is formed. The type of minerals in the water determine what type of crystals form inside the geode.

Geodes are a fun surprise of nature. You can’t know what you will find on the inside of a geode until you break it open!

During our trip to Phoenix we visited the Arizona Science Center. My daughter was very excited to find a large unopened geode in the gift shop. Here it is in its package:

The instructions said to keep it in its bag and bash it with a hammer. Here is my mini-geologist giving it a whack:

Well, it took a lot of banging and I was the one who had to deliver the final, fatal blow. I am not sure we centered our hammering too well (apparently it works MUCH better if you use a chisel first to score a line around the “equator” of the geode - see here for good instructions), but the crystalline interior is clearly visible:

Here is a close up of the surprise contents of our geode in the sunlight. Looks like lots of quartz and chalcedony:

You can find geodes in many science and museum stores, or order small and large geodes online at stores such as The Geode Gallery, The Desert USA Store or Mama’s Minerals.

My 6 year-old daughter’s favorite rock books:

Some good DK Publishing books for older children (9-12):

If you get REALLY into this geode-thing, here is a fascinating-sounding book all about geodes (written for adults, but mini-geologists might enjoy the photos):
