I LOVE the Store for Knowledge! I freely admit, that we’re all a bit on the science-nerdy side, here in the lost world, so when the opportunity to review one of their Ginormous Geodes and a laminated Introduction to Rocks poster, I jumped on it!
Intact Geodes -appearances can be deceiving!
For those who may not know, geodes are geological rock formations which occur in sedimentary and certain volcanic rocks. Geodes are essentially rock cavities or vugs with internal crystal formations or concentric banding. The exterior of the most common geodes is generally limestone or a related rock, while the interior contains quartz crystals and/or chalcedony deposits. Some geodes are completely filled with crystal, being solid all the way through.
You might find this inside a geode -
or this -
or even this!
How cool does that sound? Trust me, the crystal formations inside a geode must be seen to be believed and appreciated! Some are absolutely breath-taking and you never know, before you crack one, what you’ll find. Each is as individual and beautiful as you are!
Introduction to Rocks Poster (Laminated)
The Earth is made of rocks and this poster provides a comprehensive overview of what they are and how they are formed. It begins by explaining that rocks are made of minerals and that each type of rock is the result of a specific mixture of minerals subjected to a clearly defined geological process. The bulk of the poster is divided into three sections, one for each type of rock: igneous, sedimentary and metamorphic. An illustration shows how they are made. It is followed by photographs of a dozen representational specimens. A dramatic photograph shows a natural formation. A bonus section shows and explains some of the more specialized and popular rock forms such as geodes, concretions, agates and thunder balls. This is a great poster for earth science classes, but one also appreciated by rock collectors as it is a helpful resource for identification.
I don’t want you to think, for a minute, that the only things stocked by the Store for Knowledge are geology related. No Siree! They have a large variety of science kits, encompassing many different interests, they have building toys, dinosaur toys, room decor, books and puzzlesgalore. You’re sure to find something for everyone on your Christmas list, big or little, at the Store for Knowledge!
They even have an "ugly box" section with savings up to 50%!! The items in the ungly box section are brand new and in perfect condition, but have torn or crunched packaging. Some items may have minor defects. All package or product defects are described in the description of each product. This is a great way to save some extra money, especially if you are going to throw away the outer box. Please note ugly box items are excluded from current discounts offered. What a great idea, and one I've never seen offered anywhere else before!
OK, here’s the part you’ve been waiting for. The great folks at Store for Knowledge are giving one of my readers an chance to win a Ginormous Geode and Laminated Introduction to Rocks poster for their own lucky budding geologist to find under the tree on Christmas morning! Thank you so much!
Here’s what you do ~
