1.0 INTRODUCTION 1.1 CONCRETE: Concrete is a composite material formed by combination of cement, fine aggregates, coarse aggregate and water together in a suitable proportion. This mix form easily workable paste known as plastic wet or green concrete. After mixing and placing the concrete in position the cement and water undergoes hardening, the cement paste in this way bind the aggregate like hard mass, which is called concrete. Now a days concrete is used most commonly as a building material because

California Water Crisis What if you were not able to shower for five months, what if you could not wash your clothes, have easy access to drinking water, do your dishes, or even flush your toilet? This is the plight of many Californians in this drought. In East Portville alone, “...at least 1,300 people have lost their water…” (Source 2). In many cases in California, cities have reached detrimental drought conditions, in fact, according to a study in July, 95 percent of California now faces severe

show the properties and capabilities of super absorbent polymers and how table salt (NaCl) affects the properties of the super absorbent polymer. For this experiment we were given three vials of substances; one vial contained a small amount of powder of super absorbent polymer, one was 1/3 full with water, and the last one was 1/3 full with salt water. We were then instructed to mix these vials in order to see how the materials relate and impact each other’s physical and chemical properties. Experimental

The difference between an intensive property and an extensive property is that the extensive property of a substance whereas an intensive property does not. Density is an example of intensive property of a substance Extensive property example: mass 2. In order to calculate the density of a solid or liquid sample, what measurements are needed? Mass and volume 3. The volume of

(that is, these forces of attraction are so strong that it requires a large quantity of energy in order for the bonds to be broken). Furthermore, this compound was highly soluble in water, which is another property of ionic compounds, as when they dissolve, the ions dissociate and attach themselves to the polar ends of water molecules (cations are attracted to the localized negative poles of the oxygen atoms; anions are attracted to the localized positive poles of the hydrogen atoms). Finally, the last

Thursday, October 28 in Ms. O'Brien's science class we performed two experiments. The first experiment was called the Mixed Substances Lab. In this lab we were to see how properties of individual substances compare with properties of mixed substances. There were three research definitions that we needed to know. The first was the definition of a mixture, which is a combination of two or more substances that are not combined chemically but physically. Secondly, the definition of a homogeneous mixture

fair project is on the surface tension of water and what affects the surface tension of water. The question that I am going to ask is how does temperature and salinity of water affect the surface tension of the water. My hypothesis is that the colder and the saltier that the water is, the stronger that the surface tension of the water will be. Some of the background research that I have done has explained to me that the surface tension of water is a property of a liquids surface that can cause it

control is water not having salt, and the constant variables are the amount of water in each cup and the objects. The independent variable is the amount of salt added in the cup. The dependent variable is the height of the water and the density of the water. Background Research How do objects float on water? The density and buoyancy are properties of matter that determine how objects float on water. Density shows the amount of mass in the volume of an object. For example, the density of water is one

LAB 1 – THE SCIENTIFIC METHOD *Adapted from LabPaq CK-GCC Purpose: The purpose of this experiment is to learn about and use the Scientific Method. The discussion of physical properties such as density, color, texture, smell, and solubility will take place. Observations and Experimental Data: Table 1: Making Observations Procedure Observation A. Torn paper Vertical tear: easier to tear, more visible fibers, more jagged edges and uneven tear. Horizontal tear: harder to tear,
