Ways to save electricity Nowadays many people have electricity‚ but they don’t know how to use it wisely. There is many way to save electricity. We must use electricity wisely. 1. Way is only use electricity when needed. 2. Replace all of your inefficient incandescent light bulbs with energy efficient CFL bulbs. Replace halogen spotlights with much more efficient and longer lasting LED Spotlight. 3. Hang your clothes out to dry rather than using an electric tumble dryer. Ideally use a spin dryer before

OF SCIENCE IN HUMAN LIFE The word science comes from the Latin word “scientia” which means “knowledge”. [pic] It is a broad field of human knowledge concentrated with facts which are logically explained by rules‚ regulations and principals. The word science always lives with us. The people who study science are known as “scientists”. They perform chemical reaction and invent different objects which help us to make our life easier than before. They include

150 years ago‚ approximately around 1886‚ electricity was becoming a very exciting thing as AC plants started to appear all over the world. This meant great change for not only our establishments but also‚ for families that were near it and could afford it. It was the dawn of aluminum‚ cars and now a better way of life with electricity‚ life was about to get more exciting as well as easier for many families. Around the time of the late 1800’s‚ under the idea of “separate spheres”‚ caring for children

Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well- know effects such as lightning‚ static electricity‚ electro magnetic induction and the flow of electrical current. In addition‚ electricity permits the creation and reception of electromagnetic radiation such as radio waves. Electrical phenomena have been studied since antiquity‚ though advances in the science were not made until the seventeenth and eighteenth

Atomic Structure & Electricity 1. Draw an atom with an atomic number of 12. Label the protons‚ neutrons‚ and electrons. Use the periodic table to identify which atom you have drawn. 2. How many valence electrons are present in this atom? 2 3. Would this atom prefer to gain or lose electrons? Why? Lose‚ because the octet rule dictates that if there is less than 4 valance electrons‚ they would prefer to leave the atom. 4. Describe the differences between conductors‚ semiconductors

Hazards of Static Electricity; Lightning Lightning is a massive electrostatic discharge between the electrically charged regions within clouds or between a cloud and the surface of a planet. It is the sudden high-current discharge caused by the atmosphere’s electrical breakdown. Lightning is also one of the most deadly natural phenomena known to man. Lightning is an electric current; thus within a thundercloud up in the sky‚ many small bits of ice (frozen raindrops) collide into each other as

Living a human life/human nature Aristotle was a man of philosophy‚ science‚ and mathematics. He used these three tools to explain what he thought the purpose of being a human being was‚ and just what being a human being entailed. To describe what a human being was‚ he came up with many theories‚ which involved friendship‚ happiness‚ and human nature. He also believed that not everyone was a perfect human‚ meaning‚ there were things an individual must do throughout his or her life to achieve
