Fossil Shark Teeth
Real fossil shark teeth, some are black in colour and some are light brown or cream in colour, imported from Florida and/or Morocco. Miocene age. Larger teeth are impressive, but may not be complete with "root". Smaller teeth have a nicer shape & are more likely to be complete. Nearly all will show some natural rounding caused by erosion. Why pay big bucks for these in Banff or at fancy stores? Our prices are much more reasonable.
SHRK.06 Medium (up to 30 mm) $0.50 each
SHRK.09 Various sizes (mostly a little larger, more well-formed specimens) choice grade $2.00 each
Fossil Shark Tooth Excavation Blocks
We know teachers want to have exciting, hands-on activities for their students, but don\'t always have the time or resources to prepare materials that capture students\' interest in science. We hope this Fossil Excavation Block will provide a jump start for that interest. Excavation of fossils from the bedrock in Alberta normally requires a permit from the Alberta government, but now you can give your students the thrill of actually "digging" their own fossil, just like a real paleontologist! We make these blocks of "pseudo-rock" (semi-hard plaster/sand mixture), with a real Miocene age fossil shark tooth embedded near the centre of the block. (The fossils are imported from Florida and/or Morocco.) Sometimes if the specimen is small, we will put more than one tooth in the block. Students "excavate" their fossil with a simple scraping tool (i.e. a craft stick) to remove the fossil completely, or once exposed, leave the shark tooth half embedded for a more authentic look. Also available in sets of 12 for a ready-to-teach lesson or an emergency lesson for your substitute teacher.
FOSL.02 Single block $2.00 each
FOSL.03 Set of 12 w/Teacher\'s Guide, scraping sticks $19.95/set

Cloth Sample Bags
Designed for collecting geological samples, but could be used for any number of purposes. Simple cream-coloured cotton(?) cloth bag, 2 sizes available, string closure, large sewn-on tag for sample notes. Makes a great marble bag! The label on the bag is sewn onto the side of the bag, and sticks out like a flag on a pole. The label is approximately 2 X 3 inches, white, and made of an untearable plastic/paper material that is easy to write on with most pens or a permanent marker.

Geodes
Semi-spherical rock specimens, available in 2 sizes: slightly smaller than a golf ball and slightly larger than a marble. They don’t look like much from the outside, but crack them open with a hammer or cut them with a diamond saw, and you find that most are hollow, often with beautiful crystals lining the inside. Sometimes you get a dud, but even these can be filled with a form of agate, often showing banded colours. Lots of fun, but make sure the students wear safety glasses when pounding away on them. It’s also a good idea to wrap the geode in a rag or strong paper bag before commencing the pummeling. Sorry, but we cannot guarantee the contents or lack of same within the geodes.
ROCK.48 $3.00 each (slightly smaller than a golf ball, many irregular shapes, like small gnarly potatoes)
ROCK.66 $1.50 each (slightly larger than a marble)
Lodestone
The original magnet! Naturally-occurring iron-rich rock that is actually magnetic! Will pick up staples, gather iron filings, and deflect compass needles. Individual pieces approx. 2 to 3 cm across.
ROCK.04 $2.00 each
Pumice
Very unusual igneous rock! Produced when molten lava formed with a "froth" on it, then cooled. The millions of air pockets within this rock actually allow some specimens to float on water! Note that denser specimens do not necessarily float. Caution is necessary, as some pieces have sharp edges. Larger pieces (fist-sized and bigger) are also available, based on weight.
ROCK.05 $1.00 each (Standard 2 to 3 cm piece, may or may not float on water. Hey, it\'s a natural product, I can\'t help it!)
Rock Tumbler/Polisher Kit
Manufactured by Lortone (Model 3A), this is an excellent way to start or wrap up your "Rocks & Minerals" study unit. Transform dull, rough rocks into smooth, shiny, polished stones suitable for classroom giveaways or simple jewelry! Please note that not all rocks can be tumble polished. Trying to tumble sandstone, shale or limestone for example, will only result in a "soup" of muddy water and sand. The best candidates for tumble polishing are rocks such as agates, jaspers, petrified wood, amethyst, jade, rhodonite, sodalite, obsidian, etc. See "Mixed Tumbling Rocks" below. Full kit comes with electric motor/shaft support base, high quality water tight rubber tumbling barrel, grit kit (see below), approximately 1 pound (450 to 500 gram) bag of assorted rough rock and instruction book. High quality Lortone Rotary Rock Tumblers are quiet, durable grinding and polishing machines, capable of operating 24 hours a day for many years. (It will take 4 to 6 weeks to grind and polish a barrel of stones - 1 to 2 pounds or so.) One year manufacturer\'s warranty.
TUMB.01 $159.95 per kit
TUMB.06 $139.95 tumbler with barrel and instruction book only (no rocks, no grit kit)
Grit Kit
Refill grits for Rock Tumbler (above). Contains coarse grit, fine grit, pre-polish and polish media. Enough for 1 or 2 complete tumbling loads for above tumbler.
TUMB.02 $11.95 per kit
Mixed Tumbling Rocks
A refill of "fresh" rocks for the tumbler described above. Package contains approximately one pound (450 to 500 grams) of rough broken rocks, suitable for tumble polishing. Contains a variety of rock types, colours and sizes. May include: agates, jaspers, quartz, etc.
ROCK.35 Tumbling Mix $8.95 per package
You don’t need exotic rocks and expensive minerals to teach Rocks and Minerals. Granite and basalt, plus coarse sand with flecks of mica are your most exotic requirements. Your students will learn from those samples, then extend this knowledge to common rocks they find in their own back yards. They will identify the 3 basic rock types - igneous, sedimentary and metamorphic - and further subdivide these into 12 distinct groups based on geological formation. An egg carton organizes everything into a unique collection of personal discovery and learning experience. Book of 36 lessons, originally written for grades 6 to 12, but many lessons can be simplified for younger grades.
TOPS.23 Rocks & Minerals $26.95
