Swappin’, Part 2

While the Naturally Wild Swap Shop  is primarily for kids, I was allowed to trade so I could share the process.  I did misunderstand one of the rules, though – up to three items means three items, not three types of items.  So I traded in one Norway Spruce pine cone, one cicada, and the whole collection of shark teeth (they counted as one item).

Step three is bring in your items and discuss them with the naturalist. The first time you come, the naturalist will get your trader info: your name, your birthday, and your zip code.  She’ll also ask if you are a zoo member.  Zoo members get in free, so if you plan to trade a lot, you might think about becoming a member!

Based on this step, you move on to step four: earning points

Points are based on three things.  First is the item itself; what it is, what the condition is, how common it is.  The second is for your knowledge; what you know, what you learned that is interesting.  The third is effort; how much time did you research, how did you find it.

With all of those criteria, here are the results for my three items:

Pinecones are common and easy to get.  My cone was in excellent condition, so I got 5 points just for the cone.  Because I knew what it was, looked it up in a book, and had a lot of info, I also got 5 points for my effort and knowledge.  You don’t always get double, but in this case I did.  So 10 points for the Norway Spruce cone.

My cicada was also in excellent condition – all the “bits” were there, including both wings, all the legs, two eyes, etc.  Cicadas in good shape are worth 10 points.  The naturalist was very impressed with my information, especially since I used a dichotomous key and could tell her the species name.  I also pointed out the two things (the “cloudy Z” and the white dot) that told me what it was.  For all of that effort and knowledge, I got 15 more points!  So my cicada got me 25 points.

My shark teeth, which were tiny (all of them could fit on a quarter) but were in great condition, are not a common item.  I also had a bunch of them – if I had only had one, it wouldn’t have been worth many points. Even though I didn’t know much about them, the condition and size of the collection scored me another 100 points! 

Remember, my items were in good shape and I learned a lot about them.  If you bring in something similar, you may get the same points, but you might get less.  You may even get more!  (I hear that kids can get bonus points for being polite, waiting their turn, and asking questions.)

My total points came to 135.  Now comes the best step: trade your points!  You can bank your points, and save them up for something big.  I happen to like the Venus Comb shell, which is 700 points.  Or, if you want, you can trade in your points the same day!  I decided to go for the strawberry top shell, for 100 points.  If I get to trade again, I’ll save all the rest up for that comb shell. 

Now that you know how it’s done, plan to trade at the Naturally Wild Swap Shop the next time you come to the zoo!  Even if you don’t trade, at least check it out – with rocks, skulls, shells, bugs, and plants, there is always something cool to see and learn.  Even if you leave empty handed, you won’t leave without gaining something!

Swappin’, part 1

On August 12, the Naturally Wild Swap Shop  opened in the Children’s Zoo.  The Swap Shop is a place for kids to take items they have found in nature and trade them for other natural items.

There are certain steps to this process, along with some rules, so I decided to go through the process and help future swappers get an idea of how it works. 

Along with my birthday present, my mother-in-law sent a collection of natural items she had found (and a few of my husband’s that had been laying around her house).  I chose three to start with – and here is one of those rules, limit three items per trade.  So if you have a bunch of stuff, you’ll have to trade more than once!

The first step is to find an item.  Done.  If you are swapping, keep in mind that there is a list of things that will not be accepted.  Most of these have to do with state and federal laws.  For example, there are a lot of laws that protect birds, so nothing bird-related is accepted, including nests, eggs, and feathers.  We also don’t want people stripping our trees clean, so nothing is allowed from Zoo grounds.  You’ll have to collect before you come.

The items I have chosen are:  a bag of pine cones from an evergreen tree, two dead cicadas, and a collection of tiny sharks’ teeth.

The second step is to learn as much as you can about the item.  You get more points for your item if you know what it is and something about it.  Here’s how I started, and what I found out, for each item.

Cone and needles from a Norway Spruce

I started with the pine cones, because we have a field guide to trees on our bookshelf at home.  If you don’t have a field guide laying around, you can always check out your local library.   Flipping through the images of cones, I thought I might have a Norway Spruce on my hands.  I read the description in the book and found out that this tree is introduced, meaning that it is not originally from the US, and is used as a landscaping tree in the north.  We probably don’t have any here in Texas, but the tree these came from is in Indiana.  I also looked at some related trees, and decided that these cones are definitely from a Norway Spruce.

Dog-day cicadas

Dog-day cicadas

I don’t have an insect field guide, so I had to go to the internet to identify the cicadas.  I found this helpful website: BugGuide.net .  These cicadas are Tibicen pruinosis, a fairly common yearly cicada sometimes called a dog-day cicada.  It was pretty hard to identify them to start; I used a very scientific dichotomous key to get it down to two genera (the first word in the scientific name) but you may have to just look through pictures.  Pay attention to the tiny details – my cicadas looked a lot like other cicadas, but the “cloudy Z” on their wings and the white spot on their backs were the telltale signs.    

For the shark’s teeth, I already knew that they were sifted from the sand on a beach in North Carolina.  As I discovered by some internet browsing, identifying shark teeth is very difficult.  There are several websites that can help, but I decided to forego the extra points this time.

So I have 6 Norway Spruce cones, two Tibicen pruinosis cicadas, and some mystery shark teeth from North Carolina.  The Naturally Wild Swap Shop is open Wednesday through Saturday, so I’ll have to wait until tomorrow for the next step: bringing in the items.
