This text discusses public policy as a skill that can be learned and implemented in local, state, and federal government. The book goes through the necessary steps to work within public policy and the necessary steps to engage and implement effective policy.

Our purpose in this volume is to introduce you to the concepts of strategic public relations. Our basic assumption is that you have some general knowledge of management and business terminology; we will help you to apply that to the discipline of public relations. Our text is based in current research and scholarly knowledge of the public relations discipline as well as years of experience in professional public relations practice.

The course is an introduction to the preparation and delivery of oral presentations in an extemporaneous style. Emphasis is on ethical research, critical and logical analysis, and organization of informative and persuasive presentations.

This course assists students in developing oral communication skills. Students will be able to speak effectively and comfortably to audiences; explain the nature, value, and requirements of effective public speaking; speak effectively to groups in an academic environment; speak effectively to groups in a non-academic environment; apply principles of cultural diversity to public speaking; and, employ effective information literacy techniques in public speaking.Login: guest_oclPassword: ocl

After learning about the concept of transfer of energy, specifically the loss of kinetic energy to friction, students get a chance to test friction. Student groups are each given a wooden block and different fabrics and weights and challenged to design the "best" puck. First the class defines what makes the "best" puck. They come to realize that the most desirable puck is the one that travels the farthest, thus the puck with the least amount of friction. In the context of hockey, the "best" puck is the one that travels farthest and loses the least kinetic energy to friction. Students then apply their knowledge of friction the energy transfer from kinetic to heat energy to design new, optimal pucks for the National Hockey League.

El área total desde donde comienza el agua de un arroyo o un río hasta donde finalmente termina se llama cuenca hidrográfica (también llamada cuenca del río o cuenca del agua). Cuencas hidrográficas y líneas divisorias de las aguasson importantes para la mayoría de los seres vivos, ya que la corriente, dirección y localización del agua son vitales para disponer de agua en la vida diaria. Los ingenieros medio ambientales, químicos y civiles, junto a geólogos e hidrólogos, están todos interesados en las cuencas hidrográficas, en cómo cambian y en cómo fluye el agua a través de ellas. Recientemente, en la cronología geológica de la Tierra, estamos viendo cambios en las cuencas hidrográficas en respuesta a las actividades humanas de desvio y recogida de aguas. Comprender cómo tecnologías creadas por el hombre afectan a los recursos aquíferos, la calidad del agua y las líneas divisorias de las aguas es de suma importancia para proteger a la población, a las industrias y a la flora y fauna que dependen para sobrevivir de un sistema básico de agua limpia.

Los estudiantes diseñan, construyen y prueban puentes de celosía hechos de pajas y cinta para ver cuánto peso pueden soportar.

Los estudiantes diseñan, construyen y prueban puentes hechos de fideos de spaghetti crudos.

Using common materials (spools, string, soap), students learn how a pulley can be used to easily change the direction of a force, making the moving of large objects easier. They see the difference between fixed and movable pulleys, and the mechanical advantage gained with multiple/combined pulleys. They also learn the many ways engineers use pulleys for everyday purposes.

Pumps are used to get drinking water to our houses every day! And in disaster situations, pumps are essential to keep flood water out. In this hands-on activity, student groups design, build, test and improve devices to pump water as if they were engineers helping a rural village meet their drinking water supply. Students keep track of their materials costs, and calculate power and cost efficiencies of the prototype pumps. They also learn about different types of pumps, how they work and useful applications.

Water transport through pipes, pressure losses, (pressure) network design and building, pump selection, pumping stations, power supply, quantitative reliability, operation and maintenance.

Students observe and test their reflexes, including the (involuntary) pupillary response and (voluntary) reaction times using their dominant and non-dominant hands, as a way to further explore how reflexes occur in humans. They gain insights into how our bodies react to stimuli, and how some reactions and body movements are controlled automatically, without conscious thought. Using information from the associated lesson about how robots react to situations, including the stimulus-to-response framework, students see how engineers use human reflexes as examples for controls for robots.

In this task sutdents use a dotplot, histogram or boxplot to summarize data.

Students will investigate the interactions between colliding objects using pushes and pulls. After listening to the book, Push and Pull by Charlotte Guillian, students will play a game of kickball and observe how the ball is pushed, pulled, started, stopped, collided with other objects and how it changed position and speed. As a group, students will then brainstorm about other objects being pushed, pulled or colliding and choose one of those objects to investigate. This lesson is part of a bigger unit based on this Performance Expectation and items not addressed in this lesson are addressed in other lessons.

This lesson focuses on the conservation of energy solely between gravitational potential energy and kinetic energy, moving students into the Research and Revise step. Students start out with a virtual laboratory, and then move into the notes and working of problems as a group. A few questions are given as homework. A dry lab focuses on the kinetic and potential energies found on a roller coaster concludes the lesson in the Test Your Mettle phase of the Legacy Cycle.

This lesson contains background about the blood vascular system and the heart. Also, the different sizes of capillaries, veins, and arteries, and how they affect blood flow through the system. We will then proceed to talk about the heart's function in the blood vascular system. This will lead into a discussion of heart valves, how they work and what might cause them to fail. Then we will discuss prosthetic heart valves.

Uncountable times every day with the merest flick of a finger each one of us calls on electricity to do our bidding. What would your life be like without electricity? Students begin learning about electricity with an introduction to the most basic unit in ordinary matter, the atom. Once the components of an atom are addressed and understood, students move into the world of electricity. First, they explore static electricity, followed by basic current electricity concepts such as voltage, resistance and open/closed circuits. Next, they learn about that wonderful can full of chemicals the battery. Students may get a "charge" as they discover the difference between a conductor and an insulator. The unit concludes with lessons investigating simple circuits arranged "in series" and "in parallel," including the benefits and unique features associated with each. Through numerous hands-on activities, students move cereal and foam using charged combs, use balloons to explore electricity and charge polarization, build and use electroscopes to evaluate objects' charge intensities, construct simple switches using various materials in circuits that light bulbs, build and use simple conductivity testers to evaluate materials and solutions, build and experiment with simple series and parallel circuits, design and build their own series circuit flashlight, and draw circuits using symbols.

On the topic of energy related to motion, this summary lesson is intended to tie together the concepts introduced in the previous four lessons and show how the concepts are interconnected in everyday applications. A hands-on activity demonstrates this idea and reinforces students' math skills in calculating energy, momentum and frictional forces.

In this culminating activity of the unit, students bring together everything they've learned in order to write the code to solve the Grand Challenge. The code solution takes two images captured by robots and combines them to create an image that can be focused at different distances, similar to the way that humans can focus either near or far. They write in a derivative of C++ called QT; all code is listed in this activity.
