particles are given the sizes of equivalent spherical particles. The density of a soil-water suspension depends upon the concentration and specific gravity of the soil particles. If the suspension is allowed to stand‚ the particles will gradually settle out of the suspen- sion‚ and the density will be decreased. The hydrometer is the instrument used to measure the density of the suspension at a known depth below the surface. The density measurement‚ together with knowledge of specific gravity

Activity 3: DIY Lava Lamps Students will understand density‚ chemical reactions and simple circuits by creating a nifty take home‚ reusable lava lamp. Set-up: Every student will need two LED lights‚ two coin batteries‚ and a water bottle. Keep the water‚ vegetable oil and food coloring at a communal table so that you can track the amount each student is using. Electrical tape can be distributed to the tables to share. Demo and discussion: Although building lava lamps seems like a lighthearted

Introduction: Specific gravity or relative density is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. Temperature and pressure must be specified for both the sample and the reference. The following formula is used- Specific gravity= density of sample/density of same volume of water. Specific gravity is commonly used as a simple means of obtaining information about the concentration of solutions

Methods for studying cells in the lab Centrifugation A centrifuge is a device for separating particles from a solution according to their size‚ shape‚ density‚ viscosity of the medium and rotor speed. Centrifugation can be used to separate cells from one culture or to isolate an organelle from the rest of the cell. The process relies on speed; the faster and longer the particle is centrifuged‚ the smaller the particles are that will be separated. Separation occurs by causing the larger particles

scientifically designed to lengthen and strengthen the bone density for increased height. Pure Height Plus shares to be 100% natural‚ hence should achieve a height between 3-12 inches when used on a daily basis. Are there real proofs to show that Pure Height Plus really work to give this height range? We will get to that. In addition to the highlight of achieving increase in height‚ it is said to increase bone strength‚ enhance bone mineral density‚ and reduce the risk of osteoporosis and osteoarthritis

implement material handling systems. Material handling systems range from simple pallet rack and shelving projects‚ to complex conveyor belt and Automated Storage and Retrieval Systems (AS/RS). A more fundamental way of grouping the methods used for the bulk handling of materials‚ especially from the standpoint of the mechanics involved‚ is to consider the three main groups as: 1. continuous methods‚ 2. semi-continuous‚ or many small batches‚ methods‚ and 3. batch methods.

2102ENG : Soil Mechanics Hydrometer Analysis Semester 2‚ 2012 Introduction: The hydrometer test is an application of Stokes Law‚ which in essence states that larger particles fall more quickly in a suspending fluid‚ while finer particles remain in suspension longer. The time at which the hydrometer readings are taken determines the size of particle remaining in suspension‚ while the reading on the hydrometer determines the amount of that size. Aim: This
