## Description

EISCO 12pc Cylindrical Bars Density ID Set - Hardwood, Softwood, Aluminum, Copper, Brass, Rubber, Nylon, Derlin, PVC, Glass, Acrylic & Teflon - Includes Storage Block - Study Density & Mass: desertcart.com: Industrial & Scientific

Review: EXACTLY as presented - Exactly what I was hoping for - we are using in our auction house to assist High School team members identify materials used in products so they are able to correctly label the images and lots
Review: Missing manual - I ordered four of these and the quality was good, but there were no manuals in any of the four shipped. They were wrapped in saran wrap which didn't make sense either.

## Features

- Set of 12 cylindrical bars in a variety of materials for identification exercises and exploration of density, mass and volume. Materials included: Hardwood, Softwood, Aluminum, Copper, Brass, Rubber, Nylon, Derlin, PVC, Glass, Acrylic & Teflon. 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. This set allows learners to explore the relationship between density & mass, and how the density of a substance is constant, even as its mass and volume change
- Set includes a complete manual that describes the basics of density, mass and volume, and instructions for making calculations
- 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 the appearance, texture, hardness and density of a variety of common substances, explore volume, density & mass and provide them with quality introductory physics and chemistry concepts
