Students design and build prototypes for protective eyewear. They choose different activities or sports that require protective eyewear and design a device for that particular use. Students learn about the many ways in which the eyes can be damaged and how engineers incorporate different features and materials into eyewear designs to best protect the eyes.

Students experience the steps of the engineering design process as they design solutions for a real-world problem that could affect their health. After a quick review of the treatment processes that municipal water goes through before it comes from the tap, they learn about the still-present measurable contamination of drinking water due to anthropogenic (human-made) chemicals. Substances such as prescription medication, pesticides and hormones are detected in the drinking water supplies of American and European metropolitan cities. Using chlorine as a proxy for estrogen and other drugs found in water, student groups design and test prototype devices that remove the contamination as efficiently and effectively as possible. They use plastic tubing and assorted materials such as activated carbon, cotton balls, felt and cloth to create filters with the capability to regulate water flow to optimize the cleaning effect. They use water quality test strips to assess their success and redesign for improvement. They conclude by writing comprehensive summary design reports.

Students design and build their own model levees. Acting as engineers for their city, teams create sturdy barriers to prevent water from flooding a city in the event of a hurricane.

Students are introduced to the (hypothetical) task of developing an invisible (non-intrusive) security system to protect the school's treasured mummified troll! Solving the challenge depends on an understanding of the properties of light. After being introduced to the challenge question, students generate ideas and consider the knowledge required find solutions. They watch a portion of the "Mythbuster's Crimes and Myth-Demeanors" episode ($20), which helps direct their research and learning toward solving the challenge. They begin to study laser applications in security systems, coming to realize the role of lasers in today's society.

Students learn how biomedical engineers work with engineers and other professionals to develop dependable medical devices. Specifically, they learn about suction pumps, which are important devices to keep in good repair, especially when they are used in remote locations. Student teams brainstorm, sketch, design and create prototypes of suction pump protection devices to keep fluid from backing up and ruining the pump motors. Using a real suction pump, they conduct repeated trials to test their devices for reliability, making improvements as necessary.

A framework of public hygiene and epidemiology is given. Human pathology related to water and sanitation is dealt with, as well as the relation between health and society and environment.

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 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.

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.
