A specimen set is only as good as its key

Specimen sets fail in a specific and predictable way. The specimens are handed round, put back in the wrong compartments, a few are dropped or taken home, the printed sheet is mislaid, and what remains is a tray of unidentified pieces that nobody is confident enough to teach from. Four things prevent it, and all four should be on the order:

• A numbered tray with compartments, and specimens numbered to match. Loose specimens in a bag cannot be audited; a numbered tray can be checked in thirty seconds at the end of a lesson, which is the only time a loss can be recovered.
• An identification key as a durable document - laminated, or two copies, one of which stays in the cupboard and never goes out with the set. Ask us for a spare copy with the order. It costs almost nothing and it is the single item whose loss ruins the set.
• Specimens individually replaceable. Ask before ordering whether single specimens can be bought. Students break and lose rocks - it is not misuse, it is what happens - and a set that can be topped up stays complete for decades.
• Specimen size large enough to handle and see. A set of very small chips is cheaper and much harder to teach from, because the features a student is being asked to identify - crystal faces, cleavage, banding, grain size - need a piece big enough to hold and turn. Ask for the typical specimen size.

What a hand specimen can and cannot tell a student

A rock and mineral set is bought to teach identification, and it is worth being clear about what identification from a hand specimen actually involves - because that determines what else you need to buy.

What can be determined by hand and eye: colour and lustre, whether the mineral is translucent or opaque, crystal form where it is visible, cleavage and fracture, relative hardness, streak, apparent density by feel, grain size and texture in a rock, and whether it is layered, crystalline or fragmental. That is enough to identify a large number of common minerals and to classify rocks as igneous, sedimentary or metamorphic - which is the school and college syllabus.

What cannot: precise composition, and the distinction between minerals that look alike but differ chemically. Those need instruments, and a teaching laboratory should not pretend otherwise.

So the specimen set needs a small kit beside it, and it is routinely forgotten:

• A hand lens - the single most useful item, because grain size and crystal form are often invisible to the unaided eye.
• A streak plate, for the colour of the powdered mineral, which is far more diagnostic than the colour of the lump.
• A set of hardness references, so relative hardness can be tested rather than guessed.
• Dilute acid in a dropper bottle, for testing carbonates - the fizz is one of the most memorable tests in the subject. Treat it as a chemical: dilute, labelled, eye protection, and supervised use.
• A magnet, for the magnetic minerals.

Tell us if you want that kit quoted with the set; we would rather send it than have the set used as a display.

Ores, alloys and metals: three sets that teach a process, not a classification

The metallic ores, alloys and metals sets are often bought as if they were more rock sets, and they are doing something different and more interesting. Used together they teach extraction and use as a sequence:

• The ore - the mineral as it comes out of the ground, usually unrecognisable as the metal it contains.
• The metal - the element after extraction, which is the point at which chemistry becomes visible to a student.
• The alloy - the material actually used, and the opportunity to ask why almost nothing is made of a pure metal.

Laid out as a row - ore, metal, alloy - for two or three familiar metals, that is one of the best single demonstrations in a chemistry or materials syllabus, and it needs no apparatus at all. Buy the three sets together if you buy them, because the sequence is the lesson and no one set shows it.

For the metallography that follows this subject at a higher level - how the structure of a metal is revealed and examined - see metallurgical equipment.

The astronomy models: what each one can honestly demonstrate

• An illuminated globe is more than a map with a lamp in it. Because it is lit from inside it shows political and physical layers separately, and because it is a sphere it is the only honest way to teach that every flat map of the world distorts something - area, shape, distance or direction. That single comparison, globe against wall map, is worth a lesson.
• A solar system simulator demonstrates relative orbital motion and the reason for day, night, seasons, phases and eclipses. Its honest limitation should be taught with it: no desk model is to scale in both size and distance - if the planets were the right size relative to their orbits they would be invisible specks. Ask what the model is to scale in, say so to the class, and the model stops being misleading.
• An elementary planetarium model is for the sun-earth-moon geometry, which is the part students find hardest - why the moon has phases but is not eclipsed each month, and why eclipses are rare. A model you can hold and tilt does that better than any animation.

The physiographic relief globes, relief maps and landform models sit in our meteorology and earth science listing, along with the fossil collections and the legal questions those raise.

What to tell us when you enquire

• Which sets and how many of each - a class working in pairs needs several sets, not one large one.
• Whether numbered trays, a laminated key and a spare copy of the key are required. We would recommend all three.
• Whether individual specimens can be replaced, and the typical specimen size.
• Whether the identification kit - hand lens, streak plate, hardness references, dropper bottle, magnet - is to be quoted with the set.
• For the astronomy models: what each must be to scale in, and whether a lesson plan or chart accompanies it.
• Destination country.

Frequently asked questions

Is a set of fifty specimens better than a set of forty?

Not necessarily, and the count is the least important thing about it. A set of forty with numbered compartments, a laminated key, a spare key in the cupboard and replaceable specimens will still be teaching in twenty years. A set of fifty loose in a box with one paper sheet will be a tray of unidentified stones within two. Compare the trays and the documentation before comparing the counts.

What else do we need with a rock and mineral set?

A hand lens above all, because grain size and crystal form are often invisible to the unaided eye; then a streak plate, a set of hardness references, dilute acid in a dropper bottle for carbonates, and a magnet. Without them a set can be looked at but not worked with. Ask us to quote the kit alongside the set - it costs little and it is what turns a display into a practical.

Can students identify minerals properly from hand specimens?

They can get a long way: colour, lustre, transparency, crystal form, cleavage and fracture, relative hardness, streak, density by feel, and the texture that classifies a rock as igneous, sedimentary or metamorphic. What they cannot do is determine composition, or separate minerals that look alike but differ chemically - that needs instruments. A course that is clear about the boundary teaches better science than one that implies the eye is enough.

Why buy the ore, metal and alloy sets together?

Because the sequence is the lesson. An ore is usually unrecognisable as the metal it contains; the extracted metal is where chemistry becomes visible; the alloy is what is actually used, and raises the question of why almost nothing is made of a pure metal. Laid out as a row for two or three familiar metals it is one of the best demonstrations available with no apparatus at all - and no single set shows it.

Are the solar system models to scale?

No desk model can be to scale in both planet size and orbital distance - at true relative scale the planets would be invisible specks. Ask what a particular model is to scale in, tell the class, and the model becomes useful rather than misleading. What these models do teach well is relative motion: day and night, seasons, lunar phases and why eclipses are rare, which is the part students find hardest.

What is the single best purchase for a school geography room?

An illuminated globe, because it is the only honest way to show that every flat world map distorts something - area, shape, distance or direction - and the globe-against-wall-map comparison is worth a whole lesson. After that, a rock and mineral set with its identification kit, which supports both geography and chemistry teaching.

Key takeaways

• The key, not the count. Numbered trays, a laminated identification sheet and a spare copy decide whether a set survives.
• Ask whether single specimens can be replaced. Students break rocks; a set that can be topped up lasts decades.
• Buy the identification kit with the set - hand lens, streak plate, hardness references, dilute acid, magnet.
• Specimen size matters more than specimen count, because the diagnostic features need a piece big enough to hold and turn.
• Ore, metal and alloy sets teach a sequence. Buy the three together or the point is lost.
• Say what the astronomy models are to scale in. No desk model is to scale in both size and distance.

Notes on this listing, published rather than hidden: the product names carry the padding phrase "For Earth Science Lab", which has truncated several of them where it overflowed the field, and the names also repeat the words "Set Of" and "Set" twice in several records ("Set Of Rocks And Minerals Set OF 50"); both are being corrected. The code sequence skips GLM-0002, which suggests a record was removed or reassigned and needs a database check rather than a guess - and a GLM- code also appears inside our high school physics listing, which is a separate fault we have flagged. Specimen counts, specimen sizes, what each set contains, what accompanies it and the scale of the astronomy models will all be confirmed in writing on the quotation. Verify them before tender submission, and treat dilute acid supplied for carbonate testing as a laboratory chemical with your own institution's rules applying.
