Investigating the Effect of Temperature on the Height a Squash Ball Bounce :: Papers

Investigating the Effect of Temperature on the Height a Squash Ball Bounce Aim: To investigate the effect of temperature on the height a squash ball bounces. Prediction: I think that the higher the temperature of the squash ball, the higher the squash ball will bounce. I think that as the temperature doubles so will the height of the bounce. I think that they will be directly proportional. Scientific Knowledge: If you drop a ball onto a hard floor. It will rebound, but even the bounciest ball will not bounce back to its starting position. The ball behaves like a spherical spring. When the ball hits the floor it exerts a force on the floor and the floor exerts a force on the ball. This force compresses the ball. The force that the ground exerts on the ball does work on the ball, since it is in the same direction as the displacement. The gravitational potential energy the ball has before it is dropped is converted into kinetic energy while the ball is falling and then into elastic potential energy as the force from the ground does work on the ball. But because the material the ball is made of is not perfectly elastic, friction converts some of the energy into thermal energy. The elastic potential energy stored in the ball when it has lost all its kinetic energy is converted back into kinetic and gravitational potential energy. However the thermal energy is not converted back. The ball on the floor acts like a compressed spring. It pushes on the floor with a force proportional to its displacement from its equilibrium shape. The floor pushes back with a force of equal size in the upward direction. This force is greater in size than the weight of the ball. The resultant force is in the upward direction and the ball accelerates upward. When the ball's shape is the shape it has when it is sitting still on the floor, (just slightly squashed), there is no resultant force. When the ball's shape relaxes further, the resultant force is acting downwards. But it already has velocity in the upward direction, so the ball keeps on going upward until its speed has reached zero.

Stakeholders Influence

Stakeholders are all those who need to be considered in achieving project goals and whose participation and support are crucial to its success. Stakeholder analysis identifies all primary and secondary stakeholders who have a vested interest in the issues with which the project or policy is concerned. This information is used to assess how the interests of those stakeholders should be addressed in a project plan, policy, program, or other action. The goal of a stakeholder is to develop a strategic view of the human and institutional landscape, and the relationships between the different stakeholders and the issues they care about most. Working with your key stakeholders to flesh out unambiguous and measurable objectives will set your program off on the right track. Stakeholders provide opportunities to further align business practices with societal needs and expectations, helping to drive long-term sustainability and shareholder value. Stakeholder s is intended to help the practitioners fully realize the benefits of stakeholder engagement in their organization, to compete in an increasingly complex and ever-changing business environment, while at the same time bringing about systemic change towards sustainable development. Far West Elementary school is located in Far West in New Hampshire, which is a large metropolitan area with 2 million residents. Far West has a population of 30,000. Far West Elementary School has a student population of 700, 30% of the student having relocated from Asian countries within the last two years. Most of the student’s families are moving into the community to take advantage of the low income housing and are comforted by the presence of similar cultures. Many of the new residents have limited English writing, reading, and speaking skills. The school mission is work together as a team to promote responsibility, self esteem, and achievement that will last for a lifetime. The goal of the school is to maintain a safe and caring public school for the children, staff and the community by teaching good character throughout the school. The needs and expectations of the groups in terms of Far West Elementary School is very important because we want to promote responsibility, self esteem, and academic achievement where differenced are valued and learning is a lifelong goal. Children- The program of study for English at stage 1 aims to develop children’s independent and confident use of language in all its different forms in order to explore extend and allow reflection upon their experiences. As they develop as language users at stage 2, children learn to adapt their speaking, reading and writing to different situations, purposes and audiences across a range of genres, and learn to engage with more sophisticated layers of meaning. They also learn how language works. Parents – Parents obviously need the training to be able to help their children to work on learning the English language. It will be good for the parents to participate in the class because they will learn both stages as well. This will help the parents interact with the teachers as well as helping their children at home with homework assignments. Instructors – The instructors play an important part in the whole program. It’s the instructor responsibility is to make sure the children as well as the parents get the proper training. Being open and willing to learn about their students is a key component of teachers' learning. But this does not mean simply reading a book on cultural differences or adding a unit on different family traditions. Although these can be helpful activities, they may do little to inform teachers about the students in their classrooms. They need support of administrators and policymakers, who nowadays sometimes treat teachers as little more than test givers. Teachers also need the support of the general public. The funding institution that will fit Far West Elementary School program is called Fund for the Improvement of Education. This program supports significant program within a school. They administer grants and contracts to improve elementary and secondary education to meet state academic achievement standards. They also offer 3 million for a Teacher to Teacher Initiative that will help teachers of critical need language. If needed they also offer Teach for America, which recruit and train college graduates in communities what really need the help. Their goal is to improve the quality of education, assist all content standards, and contribute to the achievement of the elementary students. What’s also included in the program is a set curriculum that the instructor will have to go by to teach the students and parents. This will give the instructors the opportunity to be able to work towards certification or licensed for bilingual teaching. Even thought the instructors are getting the training, they will still able to start the program at least one a week until their training is over so they can learn and teach at the same time. The finding institution will also handle of cost of the training and the program for the students. The program includes the costs books for the instructors, children, and parents. To be able to continue to training for the program they have to report monthly reports for the institution so they can see how the program slowly falling into place. The funding institution will attempt to determine whether the program as implemented does what it is intended to do for the students and it is this determination of a true program that will impact the evaluation from other assessment. This program will make a big impact on the school because they will be teaching the targeted children including their parents the fundamentals of English language. The children who are in the program will get a chance to participate in other activities within the school and will also help them communicate with other in their neighborhood. This will also help the parents interact with others in the community, help children with their homework, build an relationship with the teachers, and will also help them look for jobs as well. Find for the Improvement of Education will help the school reach a higher level within the state. That will help increase more funds to help the school and if more Asian students come into the community. Reference Page Fund for the Improvement of Postsecondary Education.

The Effect Of Paced Breathing On Insomnia And Vagal...

Sleep can be effected in a number of ways whether it is by the environment, your thoughts, or your pre-sleep routine, there are multiple factors involved. Many people have their own techniques that work well for them and some doctors have recommendations of their own. The purpose of this paper is to investigate and show the effectiveness of paced breathing and breathing techniques on sleep, this will take into account peer-reviewed research, course and lecture materials. In a study used to determine the efficacy of paced breathing on insomnia and vagal activity 14 people with self reported insomnia (SRI) and 14 people who reported to be good sleepers (GS) were utilized to test the hypotheses that paced breathing would aid those with insomnia in falling asleep (Tsai, Kuo, Lee, Yang, 2014). The study measured variables such as sleep quality, sleep effectiveness, Heart rate variability, and cardiac vagal tone. For the individuals to be allowed in the SRI group they had to have difficul ty falling asleep, staying asleep, or trouble with waking up too early and not being able to go back to sleep more than 3 times per week, for 6 continuous months. All subjects of the study had to be between 20-25 years old and have a BMI within the normal range for their height and weight (18.5-24.5 Kg/m^). The subjects all had regular times that they went to bed and woke up and none reported having any history of sleep disorders such as sleep apnea or periodic limb movement, substance abuse,Show MoreRelatedThe Effects Of Sleep On Insomnia And Vagal Activity 14 People With Self Reported Insomnia867 Words   |  4 Pagesinvolved.
