Spots and Stripes: A Preschool Nature Walk

This week, for my naturalist walk at nature preschool, we talked about the two species of skunks found in Maryland: the Eastern striped skunk and the rarer, smaller Eastern spotted skunk. I brought a skunk pelt to show them, and the kids had a lot of questions.

“Turn it over!”

“What’s on the other side?”

“Where’s the bones?”

Apparently, although the kids had seen animal skulls before, they’d never seen a fur. One of their teachers explained how scientists preserve pelts of dead mammals to learn more about the animals and to teach others about them.

I pointed out that skunks have warning coloration, which is the opposite of camouflage. Instead of blending into the background, their striking black and white coloration warns other animals that they are dangerous, and not to mess with them. The scientific term for this is aposematic.

In keeping with the theme of spots and stripes, I decided that we should look for these patterns while walking. Finding stripes and spots in nature at the tail end of winter in Maryland took a little work! Frankly, everything looked brown where we were walking, with a tiny pop of color here and there.

Trees at Woodend
I did find spring flowers along the roadside: delicate white Snowdrops and flashy Glory of the Snow. Aren’t those great names for flowers?

Spring at Woodend
We noticed stripes in the tree rings of cut trees, along the bark of some tree trunks, and in little lines in the ice at the pond. We found spots of bird poop and in a series of tree slices.

But the most exciting find came when one of the teachers rolled a rotten log** and there was a yellow-spotted salamander resting beneath it! We squealed and took pictures and one of the teachers mentioned that she was going to forward this find to another preschool class and to the scientists working at the mansion. We rolled the log back to protect the salamander. I told the kids that this was really cool because they got to be citizen scientists - everyday folks whose findings help scientists.

It was a great nature walk!

Learn Bird Songs!

As we're getting ready for spring here in the northern hemisphere, it is the perfect time to start birding. I found a nice resource today to help you identify the birds in your neighborhood. Lang Elliott's Learn Bird Songs! provides photographs and recordings of nearly 40 birds common to North America. You can listen to birdsong by habitat (click on the bird pictures to find the audio files) -- countrysides, forests, cityscapes, and wetlands -- or pick a species from the main page, like Blue Jay Song and Sounds. Be sure to check out How to Learn Bird Songs for tips on memorizing the sounds made by different birds and enjoy the sounds of spring!

I like caterpillars

Today, I am pleased to announce that I have a guest blogger!

"Kerm" is 6 years old and likes to "play fun games and jump on the couch." Kerm's favorite subjects in school are science and math. When I interviewed Kerm, this is what he had to say about caterpillars:

I have a caterpillar in my room because I like studying the earth around me and I like studying bugs. I want the caterpillar to change into a butterfly. If it doesn’t, then it will probably turn into a moth. Between those two times [from caterpillar to butterfly or moth], it will turn into a cocoon. If it is a moth, I will let it out late at night. If it is a butterfly, I will let it out in the day. I feed my caterpillar leaves. Last night, I saw it nibbling on one.

If you are studying caterpillars, you might want [to read] these books:

Website(s) of the Week: Bubbles!

In honor of National Bubble Week, March 20 – 26th, here are two Websites of the Week devoted to bubbles:

First, visit the Bubble Blower Museum to learn more about all things bubble. Head to their page of Homemade Bubble Solutions or check out these World Bubble Records. [Note: The site was last updated in 2006, so some of these records may have since been broken.]

Next, be sure to drop by Bubble Town and check out their Bubble Engineering page to learn more about the science behind bubbles.

And finally, don't forget to go outside, blow your own bubbles, and enjoy spring!
