36" x 24" full color laminated poster.
This poster begins by defining a mineral. It then expands on that by exploring atoms, molecules, and crystal structure. The various crystal structures are explained. This is followed by an excellent summary of the mineral classes.
Mineral collectors and students want to identify their specimens. However, specimens of the same mineral can vary greatly in appearance, which can make that a daunting task. Identification is based on a number of properties.
This poster provides an outstanding introduction to those properties: hardness, habit, luster, cleavage, specific gravity, color, streak, and fluorescence. Illustrations are used to explain principles. Photographs of truly outstanding specimens are used as examples.
Contains 15 representative metamorphic rock specimens, each approximately 1.5" x 1.5", number-coded in a compartmented container. Grades 5-12. Ages 10-18.
Used as starch indicator, biological stain and chemical reagent. This iodine is laboratory grade and cannot be used for food or medical purposes. 500ml.

24" x 36" full color laminated poster.
This is an especially important poster because it presents the new Sibley-Ahlquist bird classification system. Based on recent DNA studies, this system uses cladistics to reconstruct the evolutionary family tree. Who would have thought that birds as diverse as flamingos, eagles, and penguins would end up in the same clade? However, this revolutionary new system has been widely accepted by North American ornithologists and has made the previous bird classification system obsolete. Although this poster shows true clades, the scientific community continues to use the order names, which are cited.
This is a truly beautiful poster, one greatly appreciated by bird lovers. It certainly enhances the decor of their home or office, yet it presents information that has even greater value. All the bird clades are explored, and all of the many classification changes resulting from the transition from orders to clades are explained. This information has never before been published in such a concise and convenient form, making this poster an essential reference for anyone seriously interested in birds.
