Basic series of 9 lattice models

9 raw materialsHandpieces of different sizessold in subdivided collector's boxWhich resources are used in the construction of cell phones ?This small collection shows nine of them: On the inside of the lid is a collection description with name, weight proportion in the cell phone and type of application.This collection was created in collaboration with the Federal Institute for Geosciences and Natural Resources in Germany (BGR). On their website you can find instructions on how to set up lessons specifically based on this collection, as well as games and more for teachers.

A versatile teaching aid for geography and biology lessons!The wooden and glass covered showcase conveys the chronology of the first appearance of new animal groups, the course of tectonic events and a plethora of other facts from historical geology. The typical rocks and index fossils for each formation are arranged in a table showing our Earth's history.Contents: 26 rocks, 9 fossils and castsDimensions: 65 x 90 cmGerman language!

Mohs hardness scale in pocket size!Three metal rods are fitted with six conically cut mineral tips. The following hardness grades are included: 5 - 6 - 6.5 - 7 - 8 - 9.The degree of hardness is engraved on each pen.Comes in a black leather pouch with instructions.For technical reasons, the colors in product photos may differ slightly from those of the original product.Our images are for reference only; when you purchase, you will receive an item of equivalent quality.

Originally developed by the GSA (Geological Society of America) based on the Munsell color system and published for use by mineralogists and geologists in the field, theMunsell Rock Color Book was revised in 2009 at the Munsell Laboratories and re-released as a weatherproof chart.The updated Munsell Rock Color Chart, featuring 115 color patches, is perfect for describing rocks while conducting fieldwork. This applies to medium- to fine-grained rocks, as well as coarse-grained rocks. For very coarse-grained rock, it is necessary to determine the color of each mineral individually.Using the color book, and provided the rock is not too coarse-grained, the mixed color of the individual minerals is determined by rotating the sample or by viewing it from a short distance. It is compared with the color chart and documented along with the color designation.The chart contains 115 Munsell notations necessary for determining stone colorsfrom the following hues: 5R, 10R, 5YR, 10YR, 5Y, 10Y, 5GY, 10GY, 5G, 10G, 5BG, 5B, 5PB, 5P, 5RP, 5YR, 5Y, 5GY, 5G, 5B + nine neutral gray tones.For technical reasons, colors in product photos may differ from those of the actual product.Our images are for reference; upon purchase, you will receive a product of equivalent quality.
