Manufacturer: American Educational Brand: American Educational Products Model: 2325

The American Educational 2325 specific gravity of minerals kit is used for geological study, and has 15 mineral specimens for calculating specific gravity, which describes the density of a mineral numerically. The kit is number coded and includes a key sheet for identification. The 2325 has a compartmented tray for display and storage, with specimens that measure 1-1/2 x 1-1/2 inches (L x W). (L is the horizontal distance from left to right; W is the horizontal distance from front to back.) Specimens in this kit may vary, based on availability at the time the product is packaged. The kit has directions for instructional use, and is suitable for grades 6 to 12 and ages 11 to 18.Science education products incorporate applied math and science principles into classroom and homeschool-based projects. 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 applic...

The Hydrometer is an instrument which is constructed on the Archimedes principle that a solid body displaces its own weight of the liquid in which it floats. Hydrometers can be divided into two general classes; namely for liquids heavier than water and for liquids lighter than water. The base hydrometer scale is Specific Gravity, in which distilled water equals 1.000 as the initial point. Liquids lighter than water are scaled below 1.000 specific gravity and liquids heavier than water are scaled above 1.000 specific gravity. Hydrometers are usually calibrated at 60°F/60°F. To determine the density of a liquid, the liquid should be at 60°F. If the temperature varies, the liquid will either contract or expand, depending upon the temperature. Where there is a variation from the standard 60°F, corrections must be applied to the hydrometer reading. To assure proper corrections, a separate accurate thermometer should be used, or a hydrometer in combination with a thermometer, which is sometimes referred...
