Powerful Pulleys
Students continue to explore the story of building a pyramid, learning about the simple machine called a pulley. They learn how a pulley can be used to change the direction of applied forces and move/lift extremely heavy objects, and the powerful mechanical advantages of using a multiple-pulley system. Students perform a simple demonstration to see the mechanical advantage of using a pulley, and they identify modern day engineering applications of pulleys. In a hands-on activity, they see how a
Engineering in Sports
Imagining themselves arriving at the Olympic gold medal soccer game in Beijing, students begin to think about how engineering is involved in sports. After a discussion of kinetic and potential energy, an associated hands-on activity gives students an opportunity to explore energy absorbing materials as they try to protect an egg from being crushed.
References 3.1 What is the value of teaching assistants? Hilary Cremin et al. (2003) in their evaluation of the ways in which teachers and teaching assistants can work together in teams, suggest that, while there is enthusiasm for additional support, little attention is given to how this actually works in classrooms. It is true that learning support staff have been introduced into classrooms without clear research evidence that they can make a difference to children's learning, but then life often moves faster than the supply of research evidence.< Acknowledgements Except for third party materials and otherwise stated (see terms and conditions), this content is made available under a Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Licence Grateful acknowledgement is made to the following for permission: 4 Conclusion This unit has explored the social impact of psychology and provided a brief historical overview to explore the diversity of psychology as a discipline. You have read about the different kinds of data that are used as evidence and the different types of methods used to gather these data. You have also gained an understanding of the ethical issues that need to be considered when conducting research. The material for this unit is taken from the introductory chapter to the course DSE212 3.1 The beginning of the research process What distinguishes psychological research from common sense is that psychologists approach information and knowledge in a systematic and consciously articulated way. They use rules and procedures about how to build and apply theories, how to design studies to test hypotheses, how to collect data and use them as evidence, and how to evaluate all forms of knowledge. (See Figure 1, ‘The cycle of enquiry’ in Box 1 2.3.2 Inner experiences A second kind of data is people's inner experiences, including their feelings, beliefs and motives. These cannot be directly seen from the outside; they remain private unless freely spoken about or expressed in some other way. Examples of these inner experiences include feelings, thoughts, images, representations, dreams, fantasies, beliefs and motivations or reasons. These are only accessible to others via verbal or written reports or as inferred from behaviours such as non-verbal communicat Introduction Ever wondered what social workers do? This brief introduction gives you some insight into social work practice and the theory which informs the practice. This unit is made up of a series of six extracts. You are introduced to the four components to good practice and will look at the importance of the following approaches to social work practice: Biography The social context of social work Responding to children’s needs Acknowledgements The content acknowledged below is used under a Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Licence.

Introduction Some elite athletes in the United Kingdom are provided with financial support to allow them to train and prepare for competition. Where does the money come from to finance this? This unit will examine this question by looking at the funding of elite sport in the UK.

This Unit will introduce you to a number of ways of representing data graphically and of summarising data numerically. You will learn the uses for pie charts, bar charts, histograms and scatterplots. You will also be introduced to various ways of summarising data and methods for assessing location and dispersion.

Honors College student Pooja Patel -- "Investigation of Threshold Energy Absorption for HPPH-mediated PDT in Pancreatic Cancer Cells" -- Our research group has been working in collaboration with physicians at Mayo Clinic to develop a method of drug and light dosimetry for photodynamic therapy (PDT). We are studying Panc-1 pancreatic cancer cells with the photosensitizer 2-[1-Hexyloxyethyl]-2-devinyl Pyrophenophorbide-a (HPPH) and 670-nm light. The goal of my project is to determine whether there
