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.

Your students will become junior detectives, honing their forensic skills by solving the mysteries surrounding a fictitious "crime scenario". They'll conduct a series of forensic analysis activities to determine if a crime has been committed. Each activity is centered around a particular analysis technique to include toxicology, chromatography, finger printing, document analysis and simulated blood typing.
