Rocks / Rock Hounds
ActivitiesLast summer, most activities took place on the sidewalk and grass by the front door. Children:

| We've got a
bucket of very dirty rocks. If you help us wash them,
you'll discover nice pieces of quartz,
mica,
and feldspar -- the three minerals that form the rock called pegmatite.
(Click on the underlined names to learn more.)
The rocks that you wash can be added to your collection. Younger children can spray and scrub some larger rocks (rocks that are way to big to fit into small mouths). |

| There are treasures hidden in our pools of water and white sand. If you carefully sift the sands, you might find nuggets of copper and bits of fool's gold. You can add your best finds to your collection. | ![]() |
| Some treasures are much too small to sift for, including real gold dust that's buried in the sand. To find the gold, you have to pan for it -- just like prospectors have done for more than 100 years. During Rock Hounds, we'll teach you how to pan. When you're done, you'll find real gold dust (just like in the photo below). | ![]() |

| In the Rock
Hounds' Garden, we've got rocks
and not much else. That makes it the perfect place to
find rocks for your collection.
Our garden contains "decorative landscape stone" bought at local stores. In early July, it included brown chert, quartzite pebbles, trap rock, salt-and-pepper granite, and something we call "geode rock." |

The Wonder Works Rock Hounds' Garden is a
smaller version of the garden described on this Web page:
< http://saltthesandbox.org/garden.htm
>
If you look near the middle of the page, you can find out which local
stores carry these types of rock.
| Once
you've searched in the garden, washed some rocks, and sifted
and panned some sand, you can step inside the air-conditioned
museum building to cool off.
As you cool off, you can complete your rock collection by gluing your discoveries to name cards. |

If you need some extra name cards, you can try
downloading this Word2000 file and printing it on cardstock:
