Aluminum Metal (20 gauge sheet) - 12" x 12" x .032"
500 grams of Aluminum Metal Shot.
Aluminum metal shot is often used in classrooms for chemistry experiments and demonstrations, such as studying chemical reactions, investigating metal properties, and exploring concepts like density and reactivity. It is commonly used in reaction experiments with acids (like hydrochloric acid) to produce hydrogen gas, allowing students to observe the properties of metal reactivity and gas evolution. Additionally, aluminum shot can be used in physics experiments to study thermal conductivity and heat transfer due to its high thermal conductivity and low density.

Animal Kingdom 2 presents the new cladistics classification system. Six newly established phyla / clades have been added as well as eleven containing only extinct species. This increased the number of phyla / clades from 27 to 44. They are grouped into the nine primary clades. This poster is an essential reference chart for teachers, students, and professionals dealing with both living and prehistoric species.

24" x 36" full color laminated poster.
Arthropods are animals that have an external skeleton. They are the most abundant animals on Earth but are often misunderstood. Spiders, millipedes, and other arthropods are often mistakenly referred to as “insects” and “bugs.” This poster explains the differences.
Each of the five clades (formerly subphylum) is carefully explored. Highly detailed illustrations show an incredible 98 species, many life size. All are identified by both common and scientific names.
Insects account for the great bulk of the arthropods, and this poster includes representatives of all the major orders. The crustaceans include crabs and lobsters as well as shrimp, krill, and even barnacles. Included with them is the giant sea scorpion; this long-extinct animal is the largest arthropod that ever lived, reaching a length of six feet.
This remarkable poster even includes the prehistoric trilobites. They were the dominant life form during the Permian but became extinct. Highly educational, very attractive, and decorative, this poster appeals to teachers, students, collectors, and professional entomologists.
