Playing with Rocks
My nephew found a really cool but simple
souvenir at the Northern Arizona Museum.
He was first attracted to the name “popcorn rock.”
I have to admit I too was very curious!
I was also attracted to the interactive/learning
experience compared to your typical selection of
stuffed animals, magnets, and generic toys stamped
with a logo. We both went to the register eager to take
our prize home. (My thoughtful and frugal nephew
picked a package with two rocks! He got to take one
back to Phoenix and I kept one here with the promise
of pictures to compare our results.)
The instructions are simple. You place rock in a
solid container, poor enough plain vinegar to cover rock
and then wait. The crystals take about two weeks
to begin to form but once they do the results
This was a fun learning experience for as little as $3.00!
I would have loved to bring this into my 4th grade classroom
for science, observation, writing, hypothesis and so much
more. You can research this rock easily on the internet
and you can find several websites to purchase it.
Thought I would share another cool find!
Learning can happen anywhere not just at
