In our everyday life‚ we make decisions‚ decisions that may change the world we live in‚ if only slightly. However‚ each decision we make has an impact on our life and is therefore important. Each time we choose one thing over another‚ we draw from our previous knowledge to make the best choice we can. However‚ the ideas and thoughts that actually dictate how we make our choices are the morals that we base our life on. For some‚ these morals are simple and do not reflect what their life means to

As stated previously the purpose of this experiment was primarily based on about chemical changes. Many chemical changes are viewed through a screen‚ or read from a book. In this experiment‚ chemical changes are viewed directly from the eyes of the scientist. The procedure first begins by gathering all needed materials. Next‚ laying the first powder on four wells‚ followed by the next powders‚ each powder was placed on four wells. The liquids were then placed on each powder using the four droppers

children who came and visited the zoo. We saw different animals in the zoo and I explained for them: This is an elephant. They are very big animals and have a long memory‚ and a very long nose called a trunk. They make trumpet sound Or This is the lion. It is the king of the jungle and goes ROARRR! This is a monkey. They spend a lot of time up in trees and like to eat fruits. This one has a banana. And this is the giraffe. It has a very long neck to reach the tender leaves up high on a tree. They are

There is no deadline or penalties when Plant Managers did not submit contract for approval. That must have raised few doubts and questions regarding the perfection of this submission. $HK 800‚000 may not be a legitimate figure to benchmark. The figure could be too high‚ plant managers are not in favour of such high end procurement figure and legitimacy of the request has been compromised at large. Plant Managers did not treat Mr Chan’s email seriously due to designation or the way of communication

Based on the challenges of observing and recording discussed in class describe two you have experienced and what you did to over come them. Educators need to observe for several reasons. A few reasons include‚ health and safety‚ plan individual and classroom curriculums‚ self evaluation and asses/evaluate the children’s development. We observe the environment for hazards to ensure

INTRODUCTION Chemical changes occur when a substance combines with another to form a new substance whether by combination reaction‚ combustion reaction‚ decomposition reaction and etc. These changes can be observed by evolutions of gas‚ appearance or disappearance of a precipitate‚ evolution or absorption of heat or even change in color.

PHYSICAL SCIENCE physical change-changes affecting the form of a chemical substance‚Physical changes are used to separate mixtures into their component compounds Example:breaking glass Chemical changes- when a substance combines with another to form a new substance ‚called chemical synthesis. Example: burning wood Law of Conservation of Mass-The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations
