Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology. EISCO Scientific manufactures and supplies lab equipment for education and industry. The company, founded in 1968 and headquartered in Rochester, NY, meets International Organization of Standardization (ISO) standard 9001: 2000. Density ID Set - 12 Cylindrical Bars in a Variety of Materials Great for identification exercises and exploration of density, mass and volume. Each cylinder is the same diameter, 0.5" (12.5mm) but each has a different length. Set includes a wooden storage block. Excellent for physics classrooms. Set includes a complete manual that describes the basics of density, mass and volume, and instructions for making calculations. Set Includes one Cylindrical Bar of each Hardwood Softwood Aluminum Copper Brass Rubber Nylon Derlin PVC Glass Acrylic Teflon Required materials (NOT included): Weight device capable of tenths of grams (i.e. spring scale or digital balance) and a metric ruler or caliper. Due to the nature of raw metals, some oxidation or corrosion due to humidity and storage may occur. Simply scuff any oxidation off to make the item look brand new again. These density metals are designed to be used in an educational setting and are not fabricated using ultra high precision machining. Expect tolerances in the +/- 5% range of any stated dimensions (although they are generally much tighter). The Eisco Labs Density Investigation series is intended to help learners become familiar with appearance, feel, texture, hardness and density of a range of common substances in addition to providing them the tools to identify and figure out mass, understand the relationship between mass, volume & density, to understand specific heat and specific gravity and provide them with quality introductory physics and chemistry concepts Eisco Scientific started over 50 years ago as a small, family-owned manufacturing company serving the science education marketplace. Since then we have grown into a multinational corporation with headquarters located in both India and the United States that serve hundreds of distributors in over 100 countries throughout the world. Our mission is simple; to be TRUSTED by educators, researchers, and scientists throughout the world to design, manufacture, and DELIVER products that allow LEARNING and the development of scientific knowledge. We produce over 6,500 unique product lines for the science education and scientific research markets. Q: Are they suitable for density experiments?
