Salt Saturation & How it Affects Salt Crystal Size 12/07/11 Research Question: How does the saturation of water affect the size of the salt crystals? This project was chosen because it was intriguing and to find out if more salt equals bigger crystals. Hypothesis: If the water is more saturated then the salt crystals will be bigger. The Independent Variable is the amount of salt in the water. The Dependent Variable is the size of the salt

Salt Marshes‚Mangroves‚and Coral Reefs Salt Marshes • Salt marshes are found along low lying coastlines where boggy ground is flooded by sea water either daily or less frequently. • Many UK salt marshes have been reclaimed for farm land‚ but those that remain provide valuable habitats where salt-tolerant plants grow and birds nest. Salt marshes also pay a vital role for coastal protection‚ they contain creeks which allow tidal waters to flow both in and out which reduces the wave energy

Mastering Chemistry Chapter 1 Notes: Mixtures‚ Solutions‚ Pure Chemical Substances‚ Compounds‚ and Elements Matter can be classified into several categories. All substances are either pure chemical substances or mixtures. Mixtures can be separated into their component parts through physical means‚ whereas pure chemical substances require chemical or nuclear reactions to separate them. Pure chemical substances can be further divided into elements or compounds. Mixtures can be either heterogeneous orhomogeneous

Jashandeep Gill Gammellos Chemistry Density is one of the fundamental principles of physics. Density is the reason why a plank of wood floats on water while a piece of metal several times smaller will sink. Density of an object is measured in g/cm³ or g/cc. The equation is D=M/V‚ D being the density of the object‚ M being the mass of the object‚ and V being the volume of the object. Mass is the space an object takes up. It is the amount of matter present in an object. Mass is measured using
