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.

This Economy Celestial Globe can be a low-cost alternative to our other Celestial Globes. It measures 8" in diameter and illustrates many of the same astronomical concepts as the larger versions. The Globe can be disassembled for easier storage. Constellations, right ascension and declination lines, and the ecliptic cover the Globe. A movable Earth and Sun complete the kit. A Teacher's Guide with assembly instructions and activities is included.

The Project Planetarium is ideal for individual study projects. Causes of 2 day and night, seasonal changes, phases of the moon, and planet locations are easily understood. The small planetarium model and solar system chart, 22"x17", may be set to show actual positions of the earth, the moon and planets at any given time. Each set includes planetarium, chart and study guide.

Features all 10 planetary orbits. The motions of the planets, their relative sizes and distances from one another are illustrated in this attractive model. This model enables the student to "see" and "feel" what the Solar System looks like. The student will be able to visualize the physical relationships between the planets and the sun, and realize a better understanding of the various motions of the planets. When used with Ptolemaic System, all the problems of the real and apparent motions become clear. Stainless steel arms. Instruction book, ?Worlds in Motion," is included.

This three dimensional model of the sun and planets teaches planet identification, sizes, distance and color. The planets may be set by month to show relative positions. A sturdy base supports the 6" diameter sun with the outer planet 18" from the sun. Illustrated Study Guide includes position table. Lesson Plan facilitates explanation of orbit and speed. 12" x 22" x 8".
Gives star positions for any date. Shows constellations, stars to 5th magnitude, nebula, Milky Way and the ecliptic. Major stars luminous for outdoor use. Has instructions, planet positions and Zodiac dial on reverse.
