Shows over 100 intricate body structures. Outside shows superficial musculature, rib-casing, etc. Torso opens to expose respiratory, circulatory, digestive, nervous, and urinary systems. Lungs, heart, stomach, liver, and intestines are removable. Stands on a base or can be laid flat. 56 pg. lesson plan included with student observations and data sheets. 28" x 12".
This pre-assembled DC motor is designed for students to learn about electromagnetic forces. The open structure resembles the diagram found in many textbooks. The polarity of the magnets can be reversed to change the direction of rotation. The motor can also be used with a rheostat to observe the change of speed with the change of current. The DC motor can stand vertically or horizontally and operates on a 1.5V battery (not included). It comes in a sturdy plastic storage case with a student activity manual Shipping weight: 11.45 oz., dimensions: 5.5" x 4.5" x 2.5".

With the full-size kit, demonstrate important density concepts to an entire classroom. Challenge students to use scientific inquiry techniques to explore geology, meteorology, freshwater and saltwater systems. Using the illuminated flow of colored fluids, students can visualize abstract concepts related to plate tectonics, sea-floor spreading, air masses, fronts, air pressure, winds, ocean currents, thermoclines, haloclines, upwelling, El Nino and more. Dimensions: 44"L x 6"H x 3.75" W. 72-page manual.
Ask your class to identify each of 12 different samples by determining their density. Each cylinder varies in size and density since it is constructed of a different material. All are 1/2" in diameter and vary in length. This kit includes: 12 samples, an attractive wood storage rack coated in linseed oil for protection from wet specimens, and detailed instructions with theory. Samples include: aluminum, brass, copper, acrylic, pyrex, rubber, delrin (plastic), PVC, PTFE, nylon, poplar and oak.
What floats in cold water, sinks in hot? Our precisely calibrated cylinder demonstrates the differing density of a liquid at different temperatures. Fits most graduated cylinders. Illustrated instructions. Good for middle school.
