In this step-by-step classroom project students examine and identify individual rock specimens. As each rock specimen is examined and identified, students progress toward the completion of their own rock reference charts. The Teacher's reference chart uses illustrations and actual specimens for students to consult as they identify unlabeled rock specimens. For grades 6-12.

Without sacrificing size or key detail this three-part replica exposes the entire length of the ear canal and Eustachian tube so that the sound waves entering the ear can be easily traced and to demonstrate how air pressure on both sides of the eardrum is equalized. The hammer, anvil, transparent ear drum, and the labyrinth all lift out for hands-on study. 18 hand-numbered anatomical features are explained in-depth in the accompanying study guide.
Six times life-size with five detachable parts including the upper hemisphere, the iris/cornea unit, the Lucite Lens that magnifies and inverts images, the transparent vitreous body, and the retina. The eyeball disassembles and reassembles with ease, so students can effectively learn through hands-on activity. A 2-page study guide highlighting its 19 principal features is included. Overall dimensions: 6x6x6 inches (15x15x15 cm) overall.

Developed by the same teacher who created our DNA Manipulatives kit, this package includes colorful, large DNA, mRNA, ribosome, tRNA and amino acid models that attach to the blackboard. Teachers use these models to simulate the protein synthesis process, and students are provided with smaller size models for hands-on learning about the process and key concepts. As part of the activities, each student is given a unique DNA sequence and is asked to identify the resulting amino acid sequence. Kit also includes an instructional CD. Adequate for a class size of 40 students with students working in groups of two.

The Edinburgh II 16" Blue Ocean Raised Relief Floor Standing World Globe sports clean, sophisticated lines, a gyro-matic full swing meridian which allows you to fully view the soft blue oceans and brightly colored landmasses. Comes with additional hardware that will allow you to change it from a floor standing globe, to a desktop globe! Standing a total of 38" tall, this beautiful world globe boasts a rich walnut finished pedestal and matching base. The sphere features both political boundaries and raised relief, providing the mapping details you have been looking for in a world globe at the price you want.
Series of eight plastic raised relief models. Relates typical surface formations to subsurface structures that are shown as graphic cross sections on each model. Helps students to better understand the development of the landscape and the factor and force influencing the development. Geologic features are numbered and keyed to a comprehensive study guide. When combined, the 8 individual models form a continuous 8-foot long graphic landscape and landform reference. Each model is 12" x 15", printed in full color on durable plastic, thermo-formed and reinforced with rigid foam.

Graphic representation of the rock beds and real rock samples. Includes comprehensive Teacher's Guide which contains lab activities, color overhead transparency, blackline reproduction master, and 20 rock and sediment specimens. Transparent model cover and marking pen also included. Grades 5-12.

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.
