...Replication of Air pressure experiment Find an air filled ball that has an air input that will allow you to increase or decrease the air pressure. I used a rubber basketball but a leather basketball would have also worked. The smaller the ball, the harder it is going to be to see the differences in bounce height. Use an air pump and an air pressure gauge to put air in the ball and to measure the air pressure in the ball. Make sure you adjust the air pressure between bounces and measure and record the pressure readings each time. Create a system to measure the height of the ball’s bounces. I used a roll of paper and marked it every six inches with painter’s tape. Use something like a camcorder to record the bounces. I setup the camcorder on a tripod and aimed it at the area where it could film the entire bounce with the measuring paper in the background. Do a test drop and view the results in the camcorder to verify it gets the entire bounce and also that the angle is correct. Record the height of the bounces at the different air pressures. Make sure the surface you are bouncing on is free of anything that may interfere with the ball bouncing. Make sure the area you are doing the experiment in is free of wind and changes in temperature during the experiment. Log the results in some form of table. I used Microsoft Excel and created a graph from the results. Using a notepad and pencil would also have...

...not just a piece of rubber or leather, no it is far more than that. I always wonder about a basketball though, why is it orange? Why does a basketball bounce like it does? The things that a basketball does deceives the mind, especially when you put it in the hands of a well-trained player. There are all different kinds of people that use a basketball. You have kids just starting out to people that have never played before to the finest athletes in the world. There are people whose expertise is dribbling and others who are much better at shooting. There are others that can jump and grab the ball 12 feet in the air and you have players that focus their game on dunking the basketball. I often wonder why a basketball looks to appealing when you see one sitting on the ground. I don’t think I have ever walked by a basketball without picking it up to dribble it a few times and if there was a rim, there’s no chance I’m not shooting it. A basketball is appealing to the eye. One of my favorite sights in the world is seeing a basketball perfectly swoosh through the net. I still often wonder how the most recent version of the basketball got to be the way we see it today. The basketball we have all come to know is an inflated sphere. Basketballs range in size from very small promotional items to regular sized and finally extra-large balls nearly a foot in diameter used in training exercises to increase the skill of players.(1) The standard size of a basketball in the NBA is 29.5 to 29...

Turn on hit highlighting for speaking browsers by selecting the Enter button Abstract (summary) TranslateAbstract Engaging children in active investigations of topics that have personal meaning for them can enhance a curriculum and a child's desire to learn. Projects are ways to help children answer their own questions and learn more about the world. Full Text * TranslateFull text * Headnote Enhance your curriculum by engaging children in active investigations of topics that have personal meaning for them. Projects are ways to help children answer their own questions and learn more about the world. A PROJECT IS an in-depth investigation of a topic worth learning more about. The study is undertaken by a small group of children within a class, by a whole class, or occasionally by an individual child. The key feature of a project is that it is a research effort focused on finding answers to questions about a topic posed by children, the teacher, or both. Rather than simply seeking right answers, the goal of a project is to learn more about a topic. The Place of Project Work The project approach should be seen as complementary to the more informal parts of the early childhood curriculum. Project work is not a separate subject; it provides contexts for applying specific skills learned in other parts of the curriculum. Nor is project work an "add on" to the basics; it is integral...

...known as Hooke’s Law: The restoring force exerted by an elastic object is proportional to how far it has been distorted from its equilibrium state. Everything we associate with springs, has some place in the behavior of balls (Bloomfield, p.69). When a ball or a spring returns to its equilibrium state, it releases stored energy. Isaac Newton and the Law of Universal Gravitation: Isaac Newton (16431727) studied gravity and its effects on falling objects. He is most famous for the three laws of motion. Newton’s law of universal gravitation states that every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The earth’s gravity exerts a downward force on the ball, called the ball’s weight. Its weight causes the ball to accelerate downward (Bloomfield p. 10). Reasoning: What does elastic mean? When a rubber band gets stretched it returns to its original shape. What is something that is not elastic? When a piece of bubble gum gets stretched, it stays stretched. It does not return to its original shape. When a ball hits the floor, the energy of the collision is stored as a physical deformation of the ball (On the Rebound, 2011 para. 3). The ball has kinetic energy just before it touches the floor. As the ball gets squeezed against the floor, kinetic energy is converted to potential energy. If all the...

...Now, Tennis Balls Are Chasing the Dogs; Penn Racquet Sports courts canine customers Dennis Berman in New York. Business Week. Suppose your industry were in free fall. What would you do to find more customers? Would you go global in search of sales? Try the Internet? How about switching species? That's the drastic move made by Penn Racquet Sports, the nation's No.1 maker of tennis balls, which is suffering from flat sales and a decade-long lull in recreational tennis. This month, Penn begins marketing its familiar, fuzzy orbs to some undeniably loyal customers: dogs. R.P. Fetchem's is a traditional tennis ball that has been gussied up as a ``natural felt fetch toy'' for pooches. ``Ten times more people own pets than play tennis,'' explains Penn President Gregg R. Weida, owner of a schnauzer named Jake. NO DYES. Penn is teaching an old ball new marketing tricks--and hoping to bounce its estimated $70 million in sales up by 5% to 10%. For the benefit of four-legged consumers, Penn has made the balls dye-free. They sport the Ralston Purina Co. logo, thanks to a licensing deal with the dog-food giant. The biggest change is the price: $4 to $5 for a can of two Fetchem's vs. $2.50 for three old-fashioned tennis balls. That hasn't deterred retailers. [pic]PetsMart Inc. will test them, ordering 400 cases for its 413 stores. ``The fact that it's got the Ralston name and the natural felt are pluses,'' says Greg Forquer, [pic]PetsMart vice-president for merchandising. But that won't...

...Person Analysis We went to local, family based cricket ball manufacturers. We observed the whole process of leather ball making which is a two steps process consisting of leather processing and stitching. We use some of the key criteria’s for person analysis Work History Cricket ball making has a major work area in leather processing. As each product being made in Meerut, by family owned businesses is particularly based in distinct villages, cricket ball making is situated in Shobhapur. It used to be the major business of many families but currently only a few players exist there. The reason being, entry of bigger players and more importantly, the manual work of leather processing which is a taboo in that place since it creates a stink and makes the place inhabitable. Nevertheless, manually processed leather has its own positives too which has made sure the sustenance of these businesses. We spoke to the workers making the balls. The roles are caste based. Lower caste people do the leather processing work. It’s a week-long process which involves cleaning the leather and drying it. Their own community people follow them in that line of work. In case of stitching too new workers are brought by the old ones and taught. People continue what their family business is into, for example for a family; its generations would continue to manufacture balls, which they have been doing since years. Training received As per survey they all received on the job training. There isn’t any...

...Pokémon are different from humans in biological structure. In fact, their matter is unstable and has a certain tendency to turn into a special form of energy. This is, however, only triggered by certain radiation. This radiation is that of Apricorns, those nut-like fruits people made Pokéballs out of in ancient times. The inside of an Apricorn's shell contains energy drainers, a sort of biological energy black holes - they let out that certain radiation and they can suck energy in to their centers. Those are there to protect the Apricorns from Pokémon that might want to eat them in a very effective way - a Pokémon that cracks the shell of an Apricorn will be hit by the radiation, turn into energy, and be sucked towards the Apricorn. This can imprison smaller Pokémon inside forever - which additionally provides the Apricorn with more power to suck in more Pokémon - or if it is a powerful Pokémon, it would feel dizzy and perhaps decide the Apricorn is not good to eat. If a Pokémon actually eats the Apricorn, however, it dies and the energy drainers release the energy they contained. Different types of Apricorns, targeted as food for different kinds of Pokémon, contain different kinds of energy drainers which suck in different types of energy - usually some form which is dominant in some Pokémon and not others (such as Water Pokémon, fast Pokémon, heavy Pokémon, etc.). All Apricorns contain some drainers for all variations, though, so they can all catch anything that is weak...

...decent thing was the fact that the ball was always pumped right. Now imagine all the new, various forms of technology that has come about since 1863: computers, smart phones, smart watches, televisions, vehicles etc., it is only right that Football has a fair share of the technological advancements. From muddy fields to constantly trimming the grass before games, Astro Turf fields are the future. They don’t just save you the stress of refilling the worn out areas and constant mowing the grass, they enhance the performance of the players. Also suitable for any weather, the astro turf fields are made of plastic blades of grass that are filled with small, crumbly rubber like shavings with gives players a better grip. Another positive about this piece of technology is that it prevents unwarranted injuries that can come from unlevelled grounds or a field consisting of many holes. Moreover, technology has played a key role with the equipment used for the game. Firstly, the advancement of shin pads; they don’t just guard the shin anymore, they are now being mad with shock absorbers, reducing the impact of a tackle on that area. The shin is a very delicate part of the body, and even the advanced shin pads can’t really prevent damage from a reckless and dangerous tackle. Secondly, the ball. Different balls are made for different leagues and for different competitions within the various leagues. Officials and players complain every now and then about the balls being played with, but as of...

...scrolled through his public profile and checked out his pictures I thought he was pretty handsome, so I sent him back a notification of interest. We exchanged a few emails before finally deciding it would be easier to text. After just a few days of chatting online and through text we decided to meet, in public, and have a drink. I opened the door of the bar; he was standing next to the pool table. I took a deep breathe, swallowed the huge knot of fear coupled with excitement that had formed in my throat. He was wearing a blue mustang t-shirt which by the look of it was also a work shirt. His shirt was worn and stained from what I would later find out was the remnants of his job at a plastic molding factory. He wore a white OSU Cowboys ball cap, which for me was a major plus since I am a huge OSU Cowboys fan. As I approached the pool...

...the United States we have the highest level of basketball, the NBA. Now even in the pros there are a few levels that can be broken down. There are the greatest players, Jordan or LeBron, and then you have players that do not even make it a full year. There is the kind of ball player that practices every single day trying to perfect his craft, and maybe make it to the pros. He is the guy that does not have the newest sneakers or the most expensive gear. That stuff does not matter to him. He will never be able to attend one pro ball game, but will never miss a game on his local television channels. He will imitate every move, like the one Iverson crossed Jordan with, and he will dedicate his life to school because he knows that basketball is merely a dream. There is the kind of baller that just does one thing, shoot the ball. He does not care about running up and down the court, dunking, or even passing. This guy is what I call a three point camper. He will be the first person down the court to wait at the nearest three point spot and continually call for the ball. He studies the art of the jump shot. He will watch the greats, like Stephen curry, and master this shot. There is the kind of ball player who obviously does...
