Materials in Our Daily Life : 95 : 21 Materials in Our Daily Life The basic aim of science is not only to study and understand natural phenomena but also to use this knowledge to make our lives more comfortable. Science and technology have enabled us to develop more economical and convenient methods to recover useful materials from nature and to put them to various uses. Chemistry has enabled us to synthesize new materials which have desired properties‚ thus‚ making them even better than natural

Aim The purpose of this experiment was to plan‚ design‚ fabricate and test the structure of a microfluidic flow structure. Background Microfluidic structures are a relatively new topic of study. While the concept of fluids and the study of the flow of fluids through all sorts of various forms of ducts‚ environments and scenarios have been extensively studied by some of the greatest minds of in history‚ the novelty of microfluidics is not surprising. This is due to the fact that despite the fact

AIMS At the end of the experiment‚ students should be able to synthesise pure aspirin using chemical tests such as esterification and recrystallization independently and to also find out the melting point range of aspirin using melting point determination. INTRODUCTION Aspirin‚ which is also known as acetylsalicylic acid‚ is one of the commonly used and widely found in any drugstore or pharmacy. Its properties make aspirin a well-rounded drug that reduces inflammation and fever and also relieves

------------------------------------------------- Scientist A scientist‚ in a broad sense‚ is one engaging in a systematic activity to acquire knowledge. In a more restricted sense‚ a scientist is an individual who uses thescientific method.[1] The person may be an expert in one or more areas of science.[2] This article focuses on the more restricted use of the word. Scientists perform research toward a more comprehensive understanding of nature‚ including physical‚ mathematical and social realms

A good scientist should possess the following qualities: 1. A scientist must be curious about the world Example: Galileo Galileo’s curiosity about the heavenly bodies made him the first person to use a telescope to study the moon‚ the sun‚ the planets and the stars. 2. A scientist is logical and systematic Example: Among the reasons why Gregor Mendel discovered the principles of heredity when others have failed was his logical experimental methods and his careful and accurate record keeping

In a way it’s the world’s most powerful computer because it can process tasks at lightning speeds and simultaneously be in control of our reflexes and every other voluntary and involuntary functions. It is the most important and complex organ as well as our core for learning At the point of birth‚ the brain weighs an average of

Nutrition is a process; it is how the body puts all the processes together in order to provide what our bodies need to be healthy‚ to grow and to maintain good health while supplying all our nutritive needs. There are different stages to nutrition‚ it starts with the food we ingest‚ then it is digested‚ it can then be used and absorbed by the body and is then assimilated and finally any waste is eliminated. At the first stage of the process is ingestion and it could be argued that good nutrition
