Filed under: Rock Hunters

Rock Hunters takes place this Friday and Saturday, from 10 a.m. to noon, at Wonder Works.

You can touch and collect real rocks and minerals, sift rocks and minerals from sand, paint a smooth pebble, and dig rocks from the playdough quarry using toy trucks and wooden trains.  Every child (and any interested adult) gets to take home a collection of small rocks and minerals that they find and label. Also, we will have lots of children’s books about rocks for you read, including the ones recommended by Shira Belenke. You can go here to see Shira’s list of recommended books.

Some folks have asked about our dirt-colored playdough. Here’s a link to the recipe, which they call “Wolrd’s Best,” and they may be right: http://www.pact.9f.com/whats_new.html   We quadrupled all the ingredients and added 35 drops each of red, yellow, and blue food coloring to make it brown, like dirt.

Here are photos of the rock and mineral collections we’ve been making at Rock Hunters.  This collection has rocks you can identify, in part, by their color:

You can learn more about these rocks at Eric’s Neighborhood Rocks website. Here are direct links to five of the types of rocks shown above:

This collection has smaller rock and mineral samples that we sifted from the sand:

In August visitors also collected minerals and rocks from crushed pegmatite, a rock type quarried from the Rocky Mountains in Colorado:

Pegmatite is made up of large crystals of quartz, feldspar, and mica. Go here to read more about pegmatite. Granite is a lot like pegmatite, but it has much smaller crystals. Visitors could glue their mineral and rock samples to a card that helps you remember their names:

If you want to know more about where the rock and mineral samples came from, or if you want copies of the cards, you can always e-mail Eric at eric@saltthesandbox.org .
