At this point in the unit, students have learned about Pascal's law, Archimedes' principle, Bernoulli's principle, and why above-ground storage tanks are of major concern in the Houston Ship Channel and other coastal areas. In this culminating activity, student groups act as engineering design teams to derive equations to determine the stability of specific above-ground storage tank scenarios with given tank specifications and liquid contents. With their floatation analyses completed and the stability determined, students analyze the tank stability in specific storm conditions. Then, teams are challenged to come up with improved storage tank designs to make them less vulnerable to uplift, displacement and buckling in storm conditions. Teams present their analyses and design ideas in short class presentations.

Students learn about linear programming (also called linear optimization) to solve engineering design problems. As they work through a word problem as a class, they learn about the ideas of constraints, feasibility and optimization related to graphing linear equalities. Then they apply this information to solve two practice engineering design problems related to optimizing materials and cost by graphing inequalities, determining coordinates and equations from their graphs, and solving their equations. It is suggested that students conduct the associated activity, Optimizing Pencils in a Tray, before this lesson, although either order is acceptable.
This materials have been compiled to support an introductory Biotechnology course for high school students.
Students use a tension-compression machine (or an alternative bone-breaking setup) to see how different bones fracture differently and with different amounts of force, depending on their body locations. Teams determine bone mass and volume, calculate bone density, and predict fracture force. Then they each test a small animal bone (chicken, turkey, cat) to failure, examining the break to analyze the fracture type. Groups conduct research about biomedical challenges, materials and repair methods, and design repair treatment plans specific to their bones and fracture types, presenting their design recommendations to the class.
Students learn about the role engineers and engineering play in repairing severe bone fractures. They acquire knowledge about the design and development of implant rods, pins, plates, screws and bone grafts. They learn about materials science, biocompatibility and minimally-invasive surgery.
Students design, build and test reflectors to measure the effect of solar reflectance on the efficiency of solar PV panels. They use a small PV panel, a multimeter, cardboard and foil to build and test their reflectors in preparation for a class competition. Then they graph and discuss their results with the class. Complete this activity as part of the Photovoltaic Efficiency unit and in conjunction with the Concentrated Solar Power lesson.
Students are introduced to the idea of improving efficiency by examining a setting that is familiar to many teenagers fast food restaurants. More specifically, they learn about the concepts of trade-offs, constraints, increasing efficiency and systems thinking. They consider how to improve efficiency in a struggling restaurant through delegating tasks, restructuring employee responsibilities and revising a floor plan, all while working within limitations and requirements. Finally, students summarize and defend their suggested changes in argumentative essays.
In this project, students take on the role of an industrial engineer and learn about user-centered product design. They will go through all of the steps of James Dyson’s design process to design a gift that other students would want to buy for one of their adult family members. Students then vote to choose two final designs to move into production and will also create marketing materials for selling the product at school or another appropriate venue.
Students are introduced to the biomechanical characteristics of helmets, and are challenged to incorporate them into designs for helmets used for various applications. By doing this, they come to understand the role of enginering associated with saftey products. The use of bicycle helmets helps to protect the brain and neck in the event of a crash. To do this effectively, helmets must have some sort of crushable material to absorb the collision forces and a strap system to make sure the protection stays in place. The exact design of a helmet depends on the needs and specifications of the user.
The Challenge Question of the Legacy Cycle draws the student into considering the engineering ingenuity of nature. It will force him to analyze, appreciate and understand the wisdom of these designs as the student team focuses on meeting each of the challenge's requirements. The student is asked, with his team members, to envision a sustainable design for a future guest village within the Saguaro National Park, outside of Tucson, Arizona. What issues need to be addressed to support the comforts of park visitors without compromising the natural resources or endangering the endemic species of the area? A deeper scope of application will reveal extensions of this design in the incorporation of urban planning and systems design. It also strengthens the concept of manufacturing and building without producing waste or pollution.
In this service-learning engineering project, students follow the steps of the engineering design process to design an assistive eating device for a client. More specifically, they design a prototype device to help a young girl who has a medical condition that restricts the motion of her joints. Her wish is to eat her favorite food, pizza, without getting her nose wet. Students learn about arthrogryposis and how it affects the human body as they act as engineers to find a solution to this open-ended design challenge and build a working prototype. This project works even better if you arrange for a client in your own community.
Students will design and build a machine to lift "barrels" of volatile chemicals from a "dangerous" spill area to a "safe" area.
During the associated lesson, students have learned about Newton's three laws of motion and free-body diagrams and have identified the forces of thrust, drag and gravity. As students begin to understand the physics behind thrust, drag and gravity and how these relate these to Newton's three laws of motion, groups assemble and launch the rockets that they designed in the associated lesson. The height of the rockets, after constructed and launched, are measured and compared to the theoretical values calculated during the rocket lesson. Effective teamwork and attention to detail is key for successful launches.
Students learn how forces affect the human skeletal system through fractures and why certain bones are more likely to break than others depending on their design and use in the body. They learn how engineers and doctors collaborate to design effective treatments with consideration for the location, fracture severity and patient age, as well as the use of biocompatible materials. Learning the lesson content prepares students for the associated activity in which they test small animal bones to failure and then design treatment repair plans.
In 2008, Dr. Michelle Soupir joined the Agriculture and Biosystems Engineering department at Iowa State University. The goal of Dr. Soupir’s research program is to conduct basic research to move us toward more sustainable water systems. Dr. Soupir uses lab- and field-based research projects to monitor the occurrence, fate and movement of nutrients and microorganisms in surface and drainage water.The information, activities and assessments included in these curriculum modules aim to tell a story. This storyline will help students learn the basics of denitrification and the nitrogen cycle to make sense of our anchor phenomenon - the Gulf Dead Zone. Students will learn that local conditions and actions can have a significant impact on global issues. The activities with which students will engage constitute a meaningful pathway to understanding and are not intended to be used in isolation. As you make plans for how these modules will be used, carefully consider the connections and interdependence of the activities, which make it difficult to separate the activities and is not advised.Each module consists of two or three activities. Each activity provides opportunities to develop and use specific elements of the Next Generation Science Standards (NGSS) science and engineering skills and practice(s) to make sense of phenomena and/or to design solutions to problems. They also provide students with the chance to use conceptual understanding that spans scientific disciplines and develop deep understanding of core ideas and content.
The purpose of the resource is to introduce students to Landsat images and how to identify the land cover types within those images.
The ocean's resources are slowly being depleted. This curriculum examines the issue of overfishing and its impact on both the environment and human life. In developing sustainable solutions, the students address the driving question: "How can we as youth, sustain the future of the world's ocean through our actions today?"
The Wasted: Don't Trash the Earth curriculum asks students to examine the impact of the waste we locally and globally produce and seek creative solutions to reduce this wastefulness by answering the driving question: "How can we, as youth, rethink waste?"
Students apply their mathematics and team building skills to explore the concept of rocketry. They learn about design issues faced by aerospace engineers when trying to launch rocketships or satellites in order to land them safely in the ocean, for example. Students learn the value of designing within constraints while brainstorming a rocketry system using provided materials and a specified project budget. Throughout the design process, teamwork is emphasized since the most successful launches occur when groups work effectively to generate creative ideas and solutions to the rocket challenge.
Students learn how roadways are designed and constructed, and discuss the advantages and limitations of the current roadway construction process. They look at current practices of roadway monitoring, discuss the limitations, and consider ways to further road monitoring research. To conclude, student groups compete to design smooth, cost-efficient and sound model road bases using gravel, sand, water and rubber (representing asphalt). This lesson prepares students for the associated activity in which they act as civil engineers hired by USDOT to research through their own model experimentation how to best use piezoelectric materials to detect road damage by showing how piezoelectric transducers can indicate road damage.
