...has mass and can takes up space. Generally, matter is not transparent like water. We can also observe matter. From this definition, we can say that matter has some criteria so that we can identify matter as a matter. Matter has four to five states according to scientists. In general they are formed in four categories. These states are as following: 1. Be Condensates 2.Solids 3.Liquids 4.Gases 5.Plasmas These states change one to another by changing their situation. This called physical change and it occurs usually when heat(energy) is either added or taken away. Each of these states also known as a phase. For example; when an ice cube melt by heating it turns in to liquid. Then if we still give heat on melted water it turn in to gases and start to disappeared in the air. By this way, energy transformed the matter in several states. Now, we are going to write down about the main forms of these states in details as below: Solid is one of the state of matter. The properties of solid is depending, how the particle are packed. Solid could be soft or hard. In solids, the particle are closely packed in a fixed position and cannot move anywhere. Solids are rigid this is why they cannot be squashed to compress. It is one of the reason that they cannot flow. Their fixed position give them a shape and fix volume as well. For example; The computer. In liquids, The particle are quite close together, but not so close...

...SBI4U Date: Designing a Controlled Experiment Step 1: Defining the Problem Every scientific investigation begins with the question that the scientist wants to answer. The questions addressed by scientific inquiry are based on observations or on information gained through previous research, or on a combination of both. Just because a question can be answered doesn’t mean that it can be answered scientifically. Step 2: Defining the Dependent and Independent Variable Dependent Variable (DV) | Variable the experimenter measures, after making changes to the IV that are assumed to affect the DV. | Independent Variable (IV) | Variable the experimenter manipulates (i.e. changes) – assumed to have a direct effect on the dependent variable. | Note: In many cases, the investigator does not manipulate the independent variable directly. He/She collects data and uses the data to evaluate the hypothesis, rather than doing a direct experiment. For example, the hypothesis that more crimes are committed during a full moon can be tested scientifically. The number of crimes committed is the dependent variable and can be measured from police reports. The phase of the moon is the independent variable. The investigator cannot deliberately change the phase of the moon, but can collect data during any phase he/she chooses. Why is the scientist limited to one independent variable per experiment? As the aim of an experiment is to see what happens when one thing is changed and how...

...SIMPLE SCIENCE EXPERIMENTS HANS JURGEN PRESS 1. Astronomy Image of the Sun Place a pair of binoculars in an open window in the direct path of the sun’s rays. Stand a mirror in front of one eyepiece so that it throws an image of the sun on to the opposite wall of the room. Adjust the mirror until the image is sharp, and darken the room. You would risk damaging your eyes if you looked directly at the sun through binoculars, but you can view the bright disc on the wall as large and clear as in the movies. Clouds and birds passing over can also be distinguished and. if the binoculars are good even sunspots. These are a few hot areas on the glowing sphere, some so big that many terrestrial globes could fit into them. Because of the earth’s rotation, the sun’s image moves quite quickly across the wall. Do not forget to re-align the binoculars from time to time onto the sun. The moon and stars cannot be observed in this way because the light coming from them is too weak. 2. Sun clock Place a flowerpot with a long stick fixed into the hole at the bottom in a spot, which is sunny, all day. The stick’s shadow moves along the rim of the pot as the sun moves. Each hour by the clock mark the position of the shadow on the pot. If the sun is shining, you can read off the time. Because of the rotation of the earth the sun apparently passes over us in a semi-circle. In the morning and evening its shadow strikes the pot superficially, while; it midday, around 12 o’clock...

...How Sugar is Made - the History It is thought that cane sugar was first used by man in Polynesia from where it spread to India. In 510 BC the Emperor Darius of what was then Persia invaded India where he found "the reed which gives honey without bees". The secret of cane sugar, as with many other of man's discoveries, was kept a closely guarded secret whilst the finished product was exported for a rich profit. It was the major expansion of the Arab peoples in the seventh century AD that led to a breaking of the secret. When they invaded Persia in 642 AD they found sugar cane being grown and learnt how sugar was made. As their expansion continued they established sugar production in other lands that they conquered including North Africa and Spain. Sugar was only discovered by western Europeans as a result of the Crusades in the 11th Century AD. Crusaders returning home talked of this "new spice" and how pleasant it was. The first sugar was recorded in England in 1099. The subsequent centuries saw a major expansion of western European trade with the East, including the importation of sugar. It is recorded, for instance, that sugar was available in London at "two shillings a pound" in 1319 AD. This equates to about US$100 per kilo at today's prices so it was very much a luxury. In the 15th century AD, European sugar was refined in Venice, confirmation that even then when quantities were small, it was difficult to transport sugar as a food grade product....

...Answers to Conceptual Integrated Science End-of-Chapter Questions Chapter 1: About Science Answers to Chapter 1 Review Questions 1 The era of modern science in the 16th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature’s behavior. 2 In Conceptual Integrated Science, we believe that focusing on math too early is a poor substitute forconcepts. 3 We mean that it must be capable of being proved wrong. 4 Nonscientific hypotheses may be perfectly reasonable; they are nonscientific only because they are not falsifiable—there is no test for possible wrongness. 5 Galileo showed the falseness of Aristotle’s claim with a single experiment—dropping heavy and lightobjects from the Leaning Tower of Pisa. 6 A scientific fact is something that competent observers can observe and agree to be true; a hypothesis is an explanation or answer that is capable of being proved wrong; a law is a hypothesis that has been tested over and over and not contradicted; a theory is a synthesis of facts and well-tested hypotheses. 7 In everyday speech, a theory is the same as a hypothesis—a statement that hasn’t been tested. 8 Theories grow stronger and more precise as they evolve to include new information. 9 The term supernatural literally means “above nature.” Science works within nature, not above it. 10 They rely on subjective personal experience and do not lead to testable hypotheses. They lie outside...

...human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, air and water heating/cooling, motor fuels, and rural energy services. Based on REN21's 2014 report, renewables contributed 19 percent to our global energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively. Both, modern renewables, such as hydro, wind, solar and biofuels, as well as traditional biomass, contributed in about equal parts to the global energy supply. Worldwide investments in renewable technologies amounted to more than US$214 billion in 2013, with countries like China and the United States heavily investing in wind, hydro, solar and biofuels. Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits. In international public opinion surveys there is strong support for promoting renewable sources such as solar power and wind power. At the national level, at least 30 nations around the world already have renewable energy contributing more than 20 percent of energy supply. National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond. While many renewable energy projects...
