Minerals Set of 20 STEM Lab Manufacturer,Supplier and Exporter in India

Product Code : SCL-MH-12485

The Minerals Set of 20 STEM Lab, curated exclusively by Educational Instrument India, is an authentic, professional-grade mineralogical collection engineered for comprehensive classroom exploration, diagnostic tracking, and experiential earth science study. This curriculum-focused kit contains 20 distinct, hand-selected mineral specimens sourced directly for their classic crystallization characteristics, mineral pathways, and baseline purity profiles.

Designed to transform theoretical planetary science into an active discovery process, this kit provides raw, unpolished mineral segments instead of polished tumblers. This preserves natural fracture lines, crystal habits, and surface textures. Students can easily implement diagnostic testing procedures, including checking for specific gravity, testing acid reactivity, performing streak evaluations, and conducting scratch resistance tests using the Mohs hardness framework. It stands as an essential foundation piece for K-12 STEM hubs, university geography departments, and material testing modules across international training channels.

Our systematically grouped inventory offers deep analytical diversity across major mineral groups, including silicates, carbonates, sulfides, halides, and native elements:

Talc (Baseline Hardness: 1)

Gypsum (Baseline Hardness: 2)

Calcite (High Carbonate Reactivity)

Fluorite (Isometric Halide Crystals)

Apatite (Phosphate Baseline Specimen)

Orthoclase Feldspar (Silicate Framework)

Quartz (Crystalline Silica)

Pyrite ("Fool's Gold" Iron Sulfide)

Hematite (Iron Oxide Compound)

Magnetite (Natural Ferrimagnetic Core)

Galena (Primary Lead Ore Matrix)

Graphite (Layered Carbon Structure)

Halite (Natural Rock Salt Crystal)

Sulfur (Native Elemental Fragment)

Muscovite Mica (Perfect Basal Cleavage)

Biotite Mica (Ferromagnesian Silicate)

Bauxite (Primary Aluminum Hydroxide Ore)

Chalcopyrite (Copper Iron Sulfide Mineral)

Olivine (Magnesium Iron Silicate)

Tourmaline (Complex Borosilicate Specimen)

3. How to Use It (Step-by-Step Practical Lab Testing Protocols)

The Minerals Set of 20 STEM Lab serves as a complete field and lab toolkit. Below are standard guidelines for running earth science experiments:

Luster and Optical Characterization: Place an unwashed mineral sample under ambient laboratory light. Have students use the pocket magnifier lens to categorize its surface sheen as Metallic (e.g., Pyrite, Galena), Vitreous/Glassy (e.g., Quartz), Pearly (e.g., Talc), or Dull/Earthy (e.g., Bauxite).

Executing a Professional Streak Test: Grip a sample firmly and draw it firmly across the surface of the unglazed porcelain streak plate. Observe the color of the left-behind mineral powder trail. This test is key for separating misleading colors from authentic compositions (e.g., Golden Pyrite leaves a greenish-black streak, while brassy Chalcopyrite leaves a distinct dark grey trail).

Evaluating Mohs Relative Hardness: Systematically perform scratching scripts across unknown blocks. Attempt to score the surface of the softest specimens (like Talc or Gypsum) using a fingernail, followed by a copper coin or a steel nail on harder minerals (like Fluorite or Quartz) to construct a relative durability ledger.

Verifying Carbonate Effervescence: Place a drop of dilute hydrochloric acid (HCl) onto the surface of the Calcite sample using a dropper pipette. Watch for instant bubbling (carbon dioxide outgassing), a clear diagnostic test for checking the presence of carbonate minerals.

Diagnostic Magnetic Separation: Pass the included testing magnet strip directly over the iron-bearing ores. Observe the strong magnetic attraction from Magnetite compared to the inert or weak response from Hematite.

4. Frequently Asked Questions (FAQs)

Q1: Are the mineral specimens authentic, or are they synthetic simulations?

A:Educational Instrument India guarantees 100% authenticity. Every sample included in our STEM lab array is natively extracted from authentic geological fields, ensuring that students interact with genuine physical profiles rather than artificial alternatives.

Q2: Are there any toxic hazards associated with specimens like Galena or Sulfur?

A: Galena contains natural lead sulfide, and Sulfur is an elemental native crystal. These samples are completely safe to inspect in typical classroom labs, provided students follow the included safety guide by washing their hands with soap after handling and avoiding inhaling dust or rubbing their eyes.

Q3: What should I do if a single sample becomes lost or degraded over time?

A: To support continuous laboratory performance, we offer individual replacement mineral specimens indexed by SKU. This allows institutions to easily refresh their inventory without needing to buy a completely new kit.

Q4: How does this kit support Google E-A-T requirements for educational buyers?

A: The kit features precision labels that match strict geological data. It includes a comprehensive instruction book compiled by credentialed earth science professors, providing schools with trusted, accurate data that aligns with official curricula.
