Last Chance! Take iTwixie's Prairie Dog Challenge!
June 5, 2012

So get this! Four, new prairie dog pup litters have already come above ground!



Hmm… does that change your guess? Help you to make one?

C’mon! Let’s get more brave girls taking the iTwixie Prairie Dog Challenge!

Here’s how:
All you have to do is make an educated guess about how many prairie dog pups will come above ground this year. That’s it! AND… you get some help!


Here’s how YOU can make an educated guess:

Use what we know:

  • There are 12 prairie dog litters. Four of them have come out of their burrow.
  • There can be between 1 and 8 pups in each litter, but the average number of pups in a litter is 5.
  • 75% of prairie dog pups born actually come out of the burrow.

This means:

  • The largest number of prairie dog pups would be 12 x 8 = 96.
  • The smallest number of prairie dog pups would be 12 x 1 = 12.
  • The most likely number would be 12 x 5 x .75 = 45.

There are no WRONG educated guesses… that’s because NO ONE KNOWS how many prairie dog babies have been born. Not even the Prairie Dog Experts!


With this information, you can make what is called an educated guess which is what a scientist calls her guess in science. This is because she uses good data to make her guess (it is not a totally random guess)!

Any guess between 12 and 96 is a good guess. We will all have to wait until all the prairie dog pups come above ground to know the correct answer.

The Prairie Dog Experts have started seeing pups above ground. iTwixie will let you know when all the litters have surfaced. There is still time to get your educated guess in!

Get guessing and enter your educated guess in the comments section below! The girl closest to the actual number of pups this year will get a SURPRISE!

The correct answer, the winner and the SURPRISE will all be announced on Thursday, June 14!

You go, girls!
