Solar System Science Project Ideas

Solar System Science Project Ideas Do you have a science fair project in your future? If so, consider focusing on the solar system. Outer space is rich with mysteries and scientific questions to explore, from the phases of the moon to the existence of space dust (micrometeorites). Start with this list of solar system science fair projects. Build a Working Sundial The ancients used sundials to tell time using the position of the Sun in the sky.  You can build your own sundial with two simple materials: a flat surface (e.g. paper, cardboard) and a thin object that can stand up (e.g. a popsicle stick or straw). Once your sundial is functional, test it for accuracy a few times per day by comparing the sundials reading to your watch or clock. Make Your Own Telescope Build a telescope. Galileo did, and so can you. Learn about the basics of telescopes  here, then check out  NASAs page on building your own. The easiest one to build is a Galileoscope, made out of a cardboard tube and some lenses.   Build a Model of the Solar System You can make a scale-model solar system out of paper or in a diorama. First, find out the distances between solar system objects, then do some math to get the distances to scale within your own model. Some tabletop scale-model solar systems contain marbles for the planets, a tennis ball for the Sun, and other smaller pebbles for asteroids and comets. Make a Spacecraft Model Build a model of a NASA space probe. Many of the major probes and space-based observatories have patterns you can download and use to make scale model, including the  Hubble Space Telescope and the NASA Jet Propulsion Laboratory. Track the Lunar Phases First, read about the phenomenon of lunar phases here. Then, for a few months, observe the Moon in the sky each night, recording how, where, and when it appears. Record the information in a chart and include a drawing of the moons shape each day.  If you have the materials, you can construct a 3D model of the sun using small balls and a light source to show how the Sun illuminates the Moon and Earth throughout the month.   Study Renewable Energy For many years, NASA and other space agencies have been using solar panels to power their satellites and the International Space Station. Here on Earth, people use solar power for everything from household electricity to powering their watches and other electronics. For a science fair project on solar power, study how the Sun generates light and heat and how we convert that light and heat into usable solar power. Collect Bits of Space Micrometeorites are tiny bits of asteroid that drift through our atmosphere and land on the surface of the Earth.  You can collect them by looking in places theyre likely to end up. For example, rain and snow can wash them off of roofs, and they can flow down the drainpipes and storm gutters. You might also try looking in the piles of dirt and sand at the bottom of a rain spout.  Collect that material, remove anything that obviously is not a micrometeorite (e.g. large rocks and leaves), and spread out the remaining material on a piece of paper. Place a magnet underneath the paper and tilt it. Most of the material will slide right off; anything that does not slide off is magnetic. Study the remaining magnetic material under a magnifying glass or microscope. Micrometeorites will appear rounded and may have pits. Edited and updated by  Carolyn Collins Petersen

5 interview questions you shouldn’t ask potential employees

5 interview questions you shouldn’t ask potential employees We talk a lot about what questions interviewees should be prepared to answer, but what if you’re on the other side of that equation? Are there any danger zone questions (or just plain ineffective) questions you shouldn’t ask? There definitely are, and they range from inappropriate to downright illegal. Let’s look at some of them. 1. How old are you?Age is always a no-no in an interview. Even if the interviewee mentions it themselves or you can deduce the age based on their resume, you can’t ask about it or use it as a factor in the hiring decision. Per the Age Discrimination in Employment Act (ADEA), it’s illegal to use age as a discriminating factor in hiring. So by mentioning age, you’re opening the door to potential legal consequences for your company- whether you’re just making small talk or not.2. Are you married/do you have kids?Again, illegal, even if it’s just small talk. The U.S. Equal Employment Opportunity Commission (EEOC) forbids using gender or family status as an element in hiring someone for a role. A question about family status could make the interviewee think you’re fishing to see if she is planning to take maternity leave, or a question about marriage could make the interviewee think you’re trying to determine sexual orientation. It’s best to leave it alone and find other ways to make small talk. And you don’t want to risk making the interviewee feel uncomfortable about having to discuss personal issues. It’s better all around to keep discussion limited to professional areas.3. If You Were a [blank], what kind of [blank] would you be?This one isn’t illegal, by any stretch. It’s just not a very useful or effective interview question. Knowing which kind of tree the interviewer identifies with or which former member of One Direction they’d like to be doesn’t tell you much of anything about how they’d approach the job at hand. Whenever possible, you should avoid filler questions like these.4. What’s your salary history?What a candidate made before is largely immaterial to what they’d make at your company, unless you’re trying to take the easy way out and determine how low you can go, salary-wise. Either way, it’s not a terribly appropriate or relevant thing to ask someone who’s applying for a specific job. It could put the interviewee on the defensive and steer the conversation away from the job itself.5. What’s your biggest weakness?If you ask this, you’re not going to get a 100% truthful answer. Candidates are on to this game, so you’re going to get an answer with spin on it. No one is going to say â€Å"Yeah, I’m just not good at motivating myself to get work done in the morning† or â€Å"I make a lot of careless mistakes.† And does the spin answer like â€Å"I am too much of a perfectionist† really help you make this hiring decision?When you’re the interviewer and have all the power, it’s important to make sure you’re making a good faith effort to ask the right questions to get someone hired. The last thing you want to do is open legal cans of worms for your company or ask questions that just don’t tell you much about the person you’re hiring to fill this job. Learning to become a great interviewer is just as much a skill as learning to become a great interviewee, and the more you work on what to avoid, the more effective you’ll be.

Barack Hussein Obama Research Paper Example | Topics and Well Written Essays - 1000 words

Barack Hussein Obama - Research Paper Example President Obama has plenty of detractors and many blame him for things that he really has no control over. But despite this, Barack Obama represents America in ways that few other Presidents have in the past. He is a unique president that has been elected because he has experiences and attributes that appeal to the rapidly changing demographics of the United States of America. An important distinction that President Obama has that makes him unique among Presidents of the United States is his ethnicity. President Obama’s mother, Ann Dunham, was a student in Honolulu, Hawaii when she met Barack Obama Sr. They were both studying in the same program at the university. Ann was from a working class family that had lived throughout the Midwest before relocating to Hawaii. She was a smart, able student with a passion for learning about cultures from all around the world. Barack Obama Sr. was from the Luo tribe in Kenya. As a child, he herded goats in his native Kenya. He was attending college on a scholarship. Ann and Barack Obama Sr. married in 1961 and Barack Obama Jr. was born a few months later. The fact that Ann was a white woman from the Midwest and Barack Obama Sr. was a black man from Africa is significant. President Obama became self-conscious about his race when he was a young teenager (Barack Obama Biography, 2011). He wondered why being black was looked down on by some white people. This is significant because President Obama is leading America during an age when ethnic minorities are the new majorities in several major metropolitan regions. America is a more ethnically diverse place and it is important that there are people in leadership that have experienced discrimination first hand. Some minorities think the Barack Obama should do more for them than he has while he has been in office. There may be few legislative victories he can point to, but it is good to have an ethnically mixed President so the issue of race can be discussed in a more constru ctive way than in the past in America. Barack is an important President for our day and age because he is a minority and that helps all Americans know that minorities are capable of sound judgment and capable leadership. Barack Obama’s parents divorced when he was two years old. He then moved to Indonesia and lived with his step-father, mother and step-sister for several years. This is a second reason that President Obama is uniquely qualified to be our President. He is the only President in the history of the United States to have lived in a Muslim country for any period of time. America’s relations with the Muslim world are at an all time low in many respects. We still have close allies such as Saudi Arabia, Qatar, Bahrain and Yemen. But many Muslim countries hate America and Americans. Having experienced Muslim culture first hand, President Obama is in a strong position to understand the Muslim world. He knows from first hand experience that not all people in the Mu slim world are bad. He understands that the vast majority of Muslims are peaceful people that want peace with America. President Obama gave a famous speech in Cairo soon after he was elected. In this speech he called for greater unity and understanding between the western, democratic nations and the Arab, Muslim nations (Holzman, 2009). It is interesting to note that many of those people that heard this speech would begin peaceful protests two years later,

Animals and Myriad Ways they can Kill or Heal Us Essay - 2

Animals and Myriad Ways they can Kill or Heal Us - Essay Example Though, the defence mechanism can differ, but it still causes serious injury to the victim (prey) or survivor (attacker). Some animals use their claws, sharp teeth or horns and other strong body parts (tail or legs) to shield and defend from the potential danger; others, intimate their opponent with stings, bites or even with a single lethal touch. The term poisonous or venomous animal is generally used to refer the category of animals, which use their poisonous toxins or venom for attack or defence. However, there is a significant difference in the meaning of poison and venom. The former is absorbed by a touch and the later is injected through a bite, sting or stab. Thus, venom containing animals purposely inject their injurious toxins and poisonous animals contain poison in their skin, which is absorbed upon a single touch. The effect of the venom differs, as it is mainly dependent upon the amount of venom injected and the physical health of the victim. Therefore, venomous animal are active slayer and poisonous animal are passive slayer. Majority of the venoms are highly complex proteins that instantly or slowly deficit nervous system of humans or animals and adversely affect the blood circulation of the victim. Marbled cone snail or conus marmoreus is categorized as the most lethal animal in the world due to its potency of venom, but specific neurotoxins or conotoxins of its unique venom are utilized by the pharmacists to produce drugs, which have the potential to cure terminal pains. These beautiful tropical and sub tropical species have approximately 700 carnivorous predator kinds and almost eighteen of them cause human envenomation. Biologically known as Conus marmoreus, are generally termed as marbled cone snail, they nourish and breed on the reef of the oceans and are known as marine snails. These species belong to family of Conidae and fall into the phylum Mollusca. Their

Female Genital Mutilation Essay -- essays research papers

For one minute I just want you to think you were born a female in an African country. Did you no you are 90% more likely to have had gone through some form of female genital mutilation. Every day, thousands of girls are targeted for mutilation. Like torture, female genital mutilation (FGM) involves the deliberate infliction of severe pain and suffering. Its effects can be life-threatening. Most survivors have to cope with the physical and mental scars for the rest of their lives. Female genital mutilation (FGM) is the partial or complete removal of the external female genitals for cultural rather than medical reasons. Other names for FGM include female circumcision or ritual female surgery. It is performed in some African, South American, Asian and Middle Eastern countries. Mutilation is a cultural rather than a religious practice, and its origins are unknown. Usually, it is performed from a few days after birth to puberty, but in some regions, the torture can be put off until just before marriage or the seventh month of pregnancy Globally, approximately 5 girls are mutilated every minute." If we do the math, we discover that equates to 300 per hour, or 7,200 per day, or 50,400 per week, or 2,620,800 per year. Considering that women make up 49% of the world, form 35% of its paid labor force, head 33% of its households, make up 95% of its nurses, perform 62% of its work hours, yet receive 10% of the world's income, own 1% of its property, make up 70% of its poor, 66% of the illiterate, 80% of the refugees, 75% of the sick, it seems to me that women--in these country’s live in a male dominated world and are there for convenience not happiness. The different types of FGM are classified by the extent of the surgery involved, and include: †¢ Type I -. The hood of skin that sits over the clitoris is removed. †¢ Type II - The entire clitoris is removed. †¢ Type III - The external genitals are partly or totally removed and the wound stitched together, leaving a small gap to allow the passage of menstrual fluid and urine †¢ Type IV - other practices including piercing, cauterizing, scraping or using corrosive substances designed to scar and narrow the vagina. In most cases only a small opening the size of the tip of a matchstick is left for th... ...fertility †¢ Painful sexual intercourse †¢ Reduced sexual enjoyment †¢ Childbirth difficulties, such as severe tearing and hemorrhage †¢ Posttraumatic stress syndrome, including nightmares and flashbacks. If this pain in known to all of the communities taking part in this practice, why is it still legal to perform? This violence has been inflicted systematically on millions of women and girls for centuries. Governments in the countries concerned have done little or nothing effective to prevent the practice. "FGM is an issue that concerns women and men who believe in equality, dignity and fairness to all human beings, regardless of gender, race, religion or ethnic identity. It must not be seen as the problem of any one group or culture, whether African, Muslim or Christian. FGM is practiced by many cultures. It represents a human tragedy and must not be used to set one person against the next, one religious group against the other, or even women against men." But just think, is it really necessary? Has anyone even bothered to ask What do these women truly want?

Case Study Principles Of Management Education Essay

Introduction: Learning is a procedure. Learn mean know something freshly. It may get cognition, behavior and accomplishment. Human acquisition may happen as portion of instruction or personal development. Learning manners are a manner to assist better personal quality and accomplishments. This differs adult male to adult male. There are many learning manners ; ocular, logical, verbal etc. There are some theoretical accounts and manners in larning like as ‘TRAP ‘ theoretical account ‘VAK ‘ theoretical account and there are some known figures who presented their position for larning. As an illustration Kolb ‘s learning rhythm. Kolb ‘s learning rhythm: Kolb presented the following learning rhythm in 1984 which is called Kolb ‘s learning rhythm. Kolb ‘s experiential acquisition theory are today good known to faculty members, instructors, pupils, directors, and trainers and every bit good as others. Successively, Kolb ‘s acquisition manners theoretical accounts and Fundamental constructs towards our apprehension and explicating human larning behavior and towards assisting others to larn besides. He described larning system in two levels- a four phase rhythm and four-type definition of larning manners. Four phase rhythms is as below: Concrete experience ( making or holding an experience or CE ) Brooding observation ( reexamining or reflecting on the experience or RO ) Abstract conceptualization ( reasoning or larning from the experience or AC ) Active experimentation ( be aftering or seeking out what anyone has learned or AE ) And these four manners are the rhythm and that is every bit below:Figure: Kolb ‘s acquisition rhythmPage-3 ( hypertext transfer protocol: //www.ldu.leeds.ac.uk/ldu/sddu_multimedia/kolb/static_version.php ) Four-type definition of larning manners, ( each stand foring the combination of two preferable manners from Kolb ‘s manner, it is like a two-by-two combination, harmonizing mathematical matrix regulations of the four-stage rhythm manners, as presented below ) , for which Kolb used the footings: Converging ( AC/AE ) Accommodating ( CE/AE ) Assimilating ( AC/RO ) Diverging ( CE/RO ) ( hypertext transfer protocol: //www.businessballs.com/kolblearningstyles.htm ) Abstract conceptualization ( AC ) Concrete experience ( CE ) Active experimentation ( AE ) Converging ( AC/AE ) Accommodating ( CE/AE ) Brooding observation ( RO ) Assimilating ( AC/RO ) Diverging ( CE/RO ) We besides can stand for it as follows ;( Class talk and class stuffs )Active experimental – abstract conceptualization Active experimental – Concrete experience Brooding observation – Concrete experience Brooding observation – Concrete experience But this tabular array can be represent in many manner merely we have to administer Diverging ( CE/RO ) Assimilating ( AC/RO ) , Assimilating ( AC/RO ) and Accommodating ( CE/AE ) in different manner. And anyone can make that and explicate in his ain manner. Now we will hold a expression how these systems adaptable encephalon or people work or execute in practically. Converging ( making and believing – AC/AE ) – this is a practical and engineering based acquisition system. Peoples with meeting larning manner attempts to work out any job utilizing their acquisition and attempts to happen work out any practical issue. They like proficient jobs and their concern about people and inter personal facets is less. They are best at happening Page-4 Practical utilizations of theories and issues. They are most attracted to proficient undertakings and jobs apart from societal and interpersonal issues. They like to make experiment with new jobs and issues. Accommodating ( making and experiencing – CE/AE ) – The people who are with Accommodating larning manner, they are really active and relies on surmising instead than logical. They use analytical theories and practical attack to make any undertaking. They prefer new challenges and they are much planned. Peoples with an Suiting acquisition manner prefer to work in squads to finish undertakings. They set marks and actively work in the field seeking different ways to accomplish an aim. Assimilating ( watching and believing – AC/RO ) – The significance of absorbing is absorbing. Absorbing larning penchant is for a concise, logical attack. Their Ideas and constructs are more of import than people. They need a good clear account instead than practical chance. They excel at understanding wide-ranging information and organizing it a clear logical format. They ever prefer to garner thoughts knowledge. Peoples with this manner are more attracted to logically sound theories than attacks based on practical value. They are really of import for effectivity in information and scientific callings. Peoples with this manner prefer readings, talks, researching analytical theoretical accounts, and holding clip to believe things exhaustively. Diverging ( experiencing and watching – CE/RO ) – People with this manner are able to look at things from different positions. They are really sensitive. They prefer to watch instead than make, be givening to garner information and usage imaginativeness to work out any job. They are good at sing concrete state of affairss several different point of views. This is called ‘Diverging ‘ manner because these people perform better, in such state of affairss that require ideas-generation, for illustration, brainstorming. They are interested in people, tend to be inventive and emotional, and be given to be strong in the humanistic disciplines. Peoples with the Diverging manner prefer to work in groups, to listen with an unfastened head and to have personal feedback. Different acquisition manners are appropriate in different phase: Human existences are ever larning. In different age and phase people learn otherwise. When we were in school we learned in one manner but after that our acquisition system has changed. And there are some people who learn faster than the other in his same age and phase. So it differ age, phase, state of affairs. There are some people who learn merely by listening. This called auditory scholar. These people they attend any category ( pupil ) or seminar or meeting any where they learn best by listening. They are really sensitive to outside noise. There are some people who learn from optic. They are called ocular scholar. Basically they learn from assortment of coloring material and image or written information. They like to read instructions and conceive of about any topics or subject. They are besides be more sensitive to ocular distraction. Page-5 There is another larning manner named kinesthetic larning manner in VAK theoretical account. This is really physical learning manner. It is like when person traveling, walking, his/her sense is larning. These scholars learn from assorted motions. When they are on any motion they use to do notes. When they read something they scan it foremost and so they focus on it. So human being, they start larning when they are childs. And that clip they learn from listening and watching. But after a certain period they learn to utilize their encephalon. They learn how to speak how to walk. Then they go to school they start their academic acquisition. Person learn by analyzing, average memorising. Person learn from understanding. Briefly, any pupil, he attend the categories and dressed ore talks and he does non necessitate to analyze more to catch the subject. But on the other manus there is person who needs to analyze more than concentrating the talks. At last when they enter their occupation there is another state of affairs. Person can think what he has to make or non. Person needs to explicate everything point to indicate. But it depends how he learns. My learning manner: I can retrieve something a long clip as I have learned it practical. If I do non understand something I try all my best to larn it. But sometimes I can non. If I can hold a expression practically any theory, I can retrieve or use, Especially Scientific footings. But sometimes when I am analyzing something I do guess and seek to compare with any practical events. I think when I do it ; I can capture it really rapidly. For an illustration when I was analyzing in secondary degree, there were a scientific theory name ‘principle of Archimedes ‘ my instructor tried his all best to do it clear to me but he failed. So he shown me this in research lab how it does work and what was the rule. Still today I can retrieve this theory and I can explicate this. Sometimes I when I am in a new phase, I try to set myself with that state of affairs and comparison with some old state of affairs to happen out the similarities. Sometimes it happens but sometimes my thoughts go incorrect. On the other manus I have seen some people who can think something, they can understand anything immediately. But I can non make the same thing. There is person who can conceive of sing any jobs, subject, or undertaking but I ca n't make the same thing. When I think something I find out some critical thoughts where as some easy thoughts could be the best solution. I ever think something which is that solution what is effectual but non instant solution means this could be use subsequently but it is a possible solution of that job. So I think I have to alter this. Another thing when I learn something from person I ca n't catch everything immediately, when I review that so I can understand that. But I think I am better, when I teach something others. And I am reflector sometimes. It is because when I tech something other chap that clip I try to retrieve my lectors and their manner. Finally, I think I have to develop my thinking power, happen out some possible easy solution. Decision: As acquisition is a uninterrupted and lifetime procedure. So it really of import to holding thoughts about assorted larning manners. And there some people who learn otherwise. And there are some celebrated people, they contribute and presented their thoughts and positions on larning procedure. And nowadays Kolb ‘s manner is popular.
