Science Education Supplies By Eisco

• This round concave glass mirror is designed for physics and educational uses.
• It is approximately 2\" (50mm) diameter and 3.3mm thick. Note, thickness varies as they are not designed to be consistent in that respect.
• Because of their educational use design, there may be minor imperfections that do not affect physical function.
• 50mm Focal Length
• Bulk lens and mirror sets available upon request.

• Single, prepared slide of a lilium anther cross section. Shows developing pollen and the first meiotic division of cells
• Demonstrates the phase of meiosis, where homologous pairs of chromosomes separate to form two haploid daughter cells
• Slide measures 75mm wide and 25mm long
• Great for biology classrooms to explore structure-function connection as per NGSS standards
• Protective cardboard casing

• Single, solid Aluminum density cube with hook and stamped with element, (Al) for easy identification
• Measures 20mm cubed. Including the hook, the cube measures 1.5\" in height
• Excellent for physics classrooms. Density Cubes have a wide range of educational applications for all grade levels, including density investigation, specific heat and specific gravity exploration
• Due to the nature of raw metals, some oxidation or corrosion due to humidity and storage may occur. Simply scuff any oxidation off to make cube look brand new again
• Designed to be used in an educational setting and are not fabricated using ultra high precision machining. Expect tolerances in the +/- 5% range of any stated dimensions (although they are generally much tighter).

• Rock gypsum specimen approximately 1\" (3cm) in length
• Formed from the lithification of sulfate evaporite deposits
• Perfect size for use in classroom identification labs and exercises, corresponding well with Next Generation Science Standards evidence statements
• Useful for rock/mineral comparison studies, as well as lessons on sedimentary rock formation
• Specimen comes in clear labeled bag for ideal storage

• Solid copper cube measuring 20mm (0.78\")
• \"Cu\" Stamped into the cube for easy identification
• Density Cubes have a wide range of educational applications for all grade levels
• Due to the nature of raw metals, some oxidation or corrosion due to humidity and storage may occur. Simply scuff any oxidation off to make cube look brand new again
• This is for one single cube without hooks - Penny used for Scale (not included

• Sphalerite sample approximately 1\" (3cm) in size
• Often mined as a zinc ore
• Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements
• Sphalerite sometimes exhibits triboluminescence, meaning it will glow when fractured
• Specimen comes in clear labeled and barcoded bag for ideal storage

• Serpentinite sample approximately 1\" (3cm) in size
• Chemically metamorphosed rock
• Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements
• This rock often forms in veins where hot water has run through rock fractures
• Specimen comes in clear labeled and barcoded bag for ideal storage

• Red slate sample approximately 1\" (3cm) in size
• Earthy, fissile metamorphic rock
• Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements
• Slate is often used in countertops or as chalkboards
• Specimen comes in clear labeled and barcoded bag for ideal storage

• Simple plastic wall thermometer
• Farenheit and Celcius readings
• 8\" Length
• 2\" Width
• Economically priced

• Arkose sample approximately 1\" (3cm) in size
• Small, angular grains indicate deposition in an ephemeral river system near to the clast source
• Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements
• Great for offering a modest challenge to students during identification and depositional history exercises
• Specimen comes in clear labeled and barcoded bag for ideal storage
