Bernido and l\faria Victoria Carpio-.Rernido Research Center for Theoretical Physics Central Visayan Institute Foundation Jagna, Bohol 6308, Philippines The Ascending Levels of Learning and Pedagogical ~1axims that could guide effective teaching of physics are presented. As an example of how these may be applied, the Dynamic Learning Prof:,lfam (DLP) of the Central Visayan Institute Foundation is briefly discussed. The DLP, together with 21st century technology, provides a scenario where the perennial lack of high school physics teachers in the Philippines can be bypassed. Introduction The breadth of topics that may be covered in teaching physics can be extremely wide. After all, physics probes the smallest things in the universe (the quarks and leptons), aiJ the way up to the "biggest" subject one can think of-the birth, death, and fate of the universe itself. One definition for physics states that it is the study of matter and energy. Most everything in the universe is either matter or energy, and this can make physics quite interdisciplinary. No wonder, therefore, that sub-areas in physics may be referred to as Biophysics, Geophysics~ Chemical Physics, Mathematical Physics, Astrophysics, Nuclear Physics, Econophysics, etc., and one also has the physics of sports, the physics of art, and so on. Because of its breadth, there is always...

...GS1140_Burke Mindy Cohen Project B: Living on another Planet/Designing a Green building Biosphere-Project — Dan Burke’s Class Purpose - A Feasibility Study - to see how different planetary light cycles/ seasonal changes and isolation does to the behavior of 25 humans, plants and animals on the surface of Mars. Duration of experiment 5 Years. **** (Why this project is not feasible at this time--We can’t work/live safely on the surface of mars without getting radiation poisoning, the atmosphere is too thin for us to breathe. It’s consists mostly of carbon dioxide, and temperatures on Mars can dip down to -87 degrees C, and rarely get above 0 degrees C). We definitely should first try to build something similar on earth, perhaps on the ocean surface or on the ocean floor- this also would be very difficult, but at least if anything goes wrong, we are not so far from home. MARS – What resources are readily available on the Surface? Weather Conditions, Gravity. How long is a day, Seasonal changes? Soil conditions? In 2013, NASA's Curiosity rover discovered that Mars' soil contains between 1.5% and 3% water by mass (about two pints of water per cubic foot or 33 liters per cubic meter, albeit attached to other compounds and thus not freely accessible). Besides silicon and oxygen, the most abundant elements in the Martian crust are iron, magnesium, aluminum, calcium, and potassium. The Phoenix lander returned data showing Martian soil to be slightly alkaline and containing elements...

Appendix Slowly, and sometimes, ever so slowly, a train of cars are being pulled up to the highest point of the roller coaster. Of course, one by one, the cars are pulled downhill until gravity takes over and push it all across the tracks. The way the roller coaster goes around is one of the best examples of how the conversion of gravitational potential energy to kinetic energy from the highest points. As the cars go up the track, it is acquiring the potential energy until the cars are at the highest point of the track. At this point, the cars have reached its maximum gravitational potential energy. Next as the cars go down the track, the potential energy is then changed to kinetic energy. Eventually the cars go up another hill and some of the kinetic energy is changed again to potential energy. This is the loop of energy conversions that go around dealing with roller coasters. Energy is the ability to do work. Roller coasters...

...Then human beings become aware of the awesome forces that are shaping Their planet. These forces are fuelled by three powerful sources of energy - heat from within the Earth, heat from the Sun, and the force of gravity. Every landform in the world has been shaped by these ttu.ee energy sources. 'the continents that drift across the surface of the globe, setting off volcanoes and earthquakes and Building mountains. are driven by heat from the Earth's interior which has a temperature of about 5000"C (9000'F). Most of this heat is created by the breakdown of radioactive elements. Earth is unique among the planets of the Solar System in having liquid water on the surface and water has a major role in shaping the planet. The warmth of the Sun evaporates water from seas and lakes. The vapor rises and condenses to form clouds and then falls again as rain and snow. It is then that its landscaping powers begin, weathering rocks and washing away the loose material. or grinding down the landscape under the power of a glacier. The Sun's heat also produces the rain and the waves that scour the land. The third force - gravity - causes the tides, which nibble away at the edges of continents, and landslides. which alter the shape of mountains. Under the influence of gravity. rain works its...

...Trebuchet Intro 1st Draft A trebuchet was the first war engine to use the laws of gravity and physics to hurl a projectile across a vast amount of space. "The Medieval Trebuchet was capable of hurling stones weighing 200 pounds with a range of up to about 300 yards," (Medieval Weapons - Trebuchet 1). Physics is a key part in contributing to the effectiveness of a trebuchet. "It relies on the principle that stored potential energy of the counterweight can be converted into kinetic energy of the payload, launching it into the air," (Science Buddies Staff 1). The trebuchet was a very advanced weapon long ago, when there were no guns or bombs, and it was a huge step toward modern war. The trebuchet was invented in China in 300BC. It dates back...

The company attempts the first step answering numerous questions related to consumer's needs, motivation and values, at it's important to understand consumers. The company constantly tests and refines its products, examines the market and competition long before starting the actual design process. 2. Ziba takes a new approach to the design process, it analyzes the customer needs from many different angles – the experience that consumers had in past, it examines competition, context and trends of the marketplace. The company focuses on a deep research of consumers' values before creating new product. Ziba indeed attempts to create a whole new brand experience to steer their clients away from the trap of “marketing myopia”. Also, I think the fact that Ziba's staff is so internationally diverse may be helpful in avoiding the marketing myopia. In such a mix of culture, intellect and experience chances to create a profound product can be significantly higher. 3. - Production concept. Ziba doesn't seem to be very very concerned about affordability of its products. It rather focuses on the whole experience, on the creation of the unique product that would delight customers. It doesn't necessarily mean that it has to be highly affordable, because that would require to cut down on the research cost and production....

...Mankind has long dreamed of touching the stars. Our first taste of expansion came with the moon. It whet humanity’s thirst for the unknown in a whole new way. Now, the biggest step after landing a man on the moon is putting one on Mars. The planet is the closest rock possibly capable of sustaining life and has been a huge subject of debate since the 1960s. Mars captivates the imagination, with many books and movies trying to guess or dream about what life there might be like. But before those dreams become reality, there are many advancements in science that need to take place, just as there were in the Space Race. This project will be intense, but like the Space Race, which brought us incredible advancements such as duct tape, GPS, and cell...

...However, their mass is so low, that they are much colder than the main sequence stars like the sun. They do have an advantage up their sleeve, however. They are able to keep the hydrogen energy stored inside their core, so red dwarfs are estimated to burn up in ten trillion years. The smallest red dwarf star ever recorded was 0.0075 times the mass of the sun. The largest was half the mass of the sun. If a star has 1.35 to 2.1 times the mass of our sun, it actually doesn’t transform into a red dwarf or a white dwarf star when it runs out of energy. A neutron star is a rare star type that is made up completely of neutrons. This occurs because of the protons and electrons in the star that are crushed together by the intense gravity. If a star is any bigger than a neutron star, they will become black holes after the supernova. Supergiant stars are the largest type of stars in the universe that humanity knows of. These stars are so massive, they can be up to dozens and dozens of times the size of the sun. The supergiant stars do not live long. They constantly consume the fuel and energy in their core until it is all gone. They only live for a few million years. That may seem like a long time, but compared to other stars, this is barely any time at all. When supergiant stars die, they explode as supernovae, which will completely destroy...

...the four types of research theories – deductive, inductive, grounded, and axiomatic. I will also discuss why and how these theories are used, and which is the most relevant, or most important. I will discuss the differences and similarities in theory and hypothesis. I will also discuss variables, and why they are important components of theoretical research. Four Types of Research Theories When doing research, it is important to first have your idea, or subject you will be researching. Once you have chosen the subject, then the research begins. There are so many places to go to use as sources. There are books, articles in magazines or newspapers, interviewing sources, and the ever growing internet. Personal experiences are another great way of getting information for your research. There are many ways to obtain information for your subject, but deciding on the subject to research is the first step. Then you need to decide how narrow or wide-ranged your topic is going to be. One example is Crime Scene Forensics. Will the paper be done on the entire subject of forensics, or will it be narrowed down to one element of forensics, such as DNA testing, or maybe ballistics? This is a decision that you will make before you start researching the subject. A very intelligent instructor, said to choose something that interests you and the researching will be a lot more interesting and fun to do. I think this is a very good concept to remember about research, and can also make...

...aman Research Institute (RRI) is an institute of scientific research located in Bangalore, India. It was founded by Nobel laureate C. V. Raman. Although it began as an institute privately owned by Sir C. V. Raman, it is now funded by the government of India. Contents * 1 Research * 2 History * 3 Achievements * 4 External links | Research The main areas of research are: * Astronomy and Astrophysics * Liquid Crystals * Theoretical Physics * Optics History Much before Raman thought about founding a research institute of his own, he had approached the then Maharaja of Mysore seeking land to build office and conference premises for the Indian Academy of Sciences (IAS), which was again a brainchild of Raman's. The Maharaja readily acceded to Raman's request and a 10-acre (40,000 m2) plot of land in the posh Malleshwaram suburb of Bangalore was alloted to the Indian Academy of Sciences in 1934. However, the Academy (headed by Raman) made no use of the land for seven years. According to the terms of the allotment, the land could be resumed by the government of Mysore at the end of 1941, if it remained unused. Therefore, in 1941, Raman as President of the IAS held an extraordinary meeting of the academy and proposed that a research institute (to be named after himself) be build on the land. This proposal was sanctioned and a stone was laid on the ground, signifying that the land was now in use. However, it was not until 1948 that the institute could be inaugurated...
