importance through my studies that we are running out of water and that there is something YOU can do to help out. My main purpose in this study is to inform young adults ages 15 through 35 on how to conserve and protect our water supply‚ by doing simple task throughout their daily lives. I chose to pick this age group because they are young and can still make an impact in our society by spreading it to others in their surroundings. There are many different ways to conserve our Nations water supply‚ but

packed closely together‚ but they are able to move around. Hence a fluid does not have a rigid shape‚ but adapts to the contours of the container that holds it. Like a liquid a gas has no fixed shape‚ but it has little resistance to compression because there is enough empty space for the molecules to move closer. Whereas a liquid placed in a container will form a puddle at the bottom of the container‚ a gas will expand to fill the container. Although the three categories seem very well defined

Objective: The main objective is to demonstrate the law of Conservation of Mass. Use Vinegar and baking soda to demonstrate the law of Conservation of Mass. Introduction: The law of Conservation of Mass states that mass is neither created nor destroyed during ordinary chemical reactions or physical changes‚ which means that no matter how dramatic of a change that a substance goes through‚ it will not lose mass. It may seem like it lost mass‚ and usually‚ if you weighed the result‚ it will have

OIL CONSERVATION In view of the need to reduce the ever-increasing gap between demand and indigenous supply of crude oil and petroleum products the Government has accorded top priority to conservation of petroleum products. Towards this end various steps to promote conservation of petroleum products in the transport‚ industrial‚ agricultural and domestic sectors have been initiated. These include adoption of measures and practices which are conducive to increase fuel efficiency and training

of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof hot-plate‚ and one using a rotovap. III. Theory Fig. 1a+1b. Figure 1a shows how water and oil separate in the separatory funnel‚ while figure 1b shows the actual apparatus. Liquid-Liquid extraction is a versatile and dependable

Jean Piaget (1896-1980) Piaget was a Swiss developmental psychologist and a philosopher known for his epistemological studies with children and his theory of cognitive development. He was born on August 9‚ 1896 in Neuchâtel‚ Switzerland. He was the eldest son of Arthur Piaget who was a Swiss professor of medieval literature and Rebecca Jackson‚ an intelligent and energetic woman‚ who was French. He attended the University of Neuchâtel where he received a degree in zoology in 1918. He then studied

Vygotsky & Piaget Cognitive Development Vygotsky and Piaget both had many theories on cognitive development. Some were similar and some were different. They discussed areas such as the relationship between learning and development and the way children’s cognitive abilities develop. I would personally like to integrate many of their wise theories into my classroom. Piaget and Vygotsky had similar views on many things and within those similarities were differences. Piaget believed that thinking

Initially‚ it was difficult to find out the appropriate age group for the assigned lab experiment. Later on‚ I found the kids with appropriate ages. One kid was from pre-operational stage who was 3 years old and another was from concrete stage who was 7 years old. I asked them several question while experimenting the things. Both kids were tested at different time period at different place but the questions which were supposed to ask them were the same. First of all‚ I asked a kid from Piaget’s
