This is an advanced course on modeling, design, integration and best practices for use of machine elements such as bearings, springs, gears, cams and mechanisms. Modeling and analysis of these elements is based upon extensive application of physics, mathematics and core mechanical engineering principles (solid mechanics, fluid mechanics, manufacturing, estimation, computer simulation, etc.). These principles are reinforced via (1) hands-on laboratory experiences wherein students conduct experiments and disassemble machines and (2) a substantial design project wherein students model, design, fabricate and characterize a mechanical system that is relevant to a real world application. Students master the materials via problems sets that are directly related to, and coordinated with, the deliverables of their project. Student assessment is based upon mastery of the course materials and the student's ability to synthesize, model and fabricate a mechanical device subject to engineering constraints (e.g. cost and time/schedule).

Under the "The Science Behind Harry Potter" theme, a succession of diverse complex scientific topics are presented to students through direct immersive interaction. Student interest is piqued by the incorporation of popular culture into the classroom via a series of interactive, hands-on Harry Potter/movie-themed lessons and activities. They learn about the basics of acid/base chemistry (invisible ink), genetics and trait prediction (parseltongue trait in families), and force and projectile motion (motion of the thrown remembrall). In each lesson and activity, students are also made aware of the engineering connections to these fields of scientific study.

This biomimetic engineering challenge introduces students to the fields of nanotechnology and biomimicry. Students explore how to modify surfaces such as wood or cotton fabric at the nanoscale. They create specialized materials with features such as waterproofing and stain resistance. The challenge starts with student teams identifying an intended user and developing scenarios for using their developed material. Students then design and create their specialized material using everyday materials. Each students test each design under specific testing constraints to determine the hydrophobicity of the material. After testing, teams iterate ways to improve their self-cleaning superhydrophobic modification technique for their design. After iterating and testing their designs, students present their final product and results to the class.
Students design a temporary habitat for a future classroom pet—a hingeback tortoise. …
Students design a temporary habitat for a future classroom pet—a hingeback tortoise. Based on their background research, students identify what type of environment this tortoise needs and how to recreate that environment in the classroom. The students divide into groups and investigate the features of a habitat for a hingeback tortoise. These features include how many holes a temporary habitat may need, the animal’s ideal type of bedding, and how much water is needed to create the necessary humidity level within the tortoise’s environment. Each group communicates and presents this information to the rest of the class after they research, brainstorm, collect and analyze data, and design their final plan.

This unit covers the broad spectrum of topics that make-up our very amazing human body. Students are introduced to the space environment and learn the major differences between the environment on Earth and that of outer space. The engineering challenges that arise because of these discrepancies are also discussed. Then, students dive into the different components that make up the human body: muscles, bones and joints, the digestive and circulatory systems, the nervous and endocrine systems, the urinary system, the respiratory system, and finally the immune system. Students learn about the different types of muscles in the human body and the effects of microgravity on muscles. Also, they learn about the skeleton, the number of and types of bones in the body, and how outer space affects astronauts' bones. In the lessons on the digestive, circulatory, nervous and endocrine systems, students learn how these vital system work and the challenges faced by astronauts whose systems are impacted by spaceflight. And lastly, advances in engineering technology are discussed through the lessons on the urinary, respiratory and immune systems while students learn how these systems work with all the other body components to help keep the human body healthy.

Students learn how healthy human heart valves function and the different diseases that can affect heart valves. They also learn about devices and procedures that biomedical engineers have designed to help people with damaged or diseased heart valves. Students learn about the pros and cons of different materials and how doctors choose which engineered artificial heart valves are appropriate for certain people.

Examines theories and practice of environmental justice, concerns about race, poverty, and the environment in both domestic and international contexts, exploring and critically analyzing philosophies, frameworks, and strategies underlying environmental justice movements. Examines case studies of environmental injustices, including: distribution of environmental quality and health, unequal enforcement of regulations, unequal access to resources to respond to environmental problems, and the broader political economy of decision-making around environmental issues. Explores how environmental justice movements relate to broader sustainable development goals and strategies. This class explores the foundations of the environmental justice movement, current and emerging issues, and the application of environmental justice analysis to environmental policy and planning. It examines claims made by diverse groups along with the policy and civil society responses that address perceived inequity and injustice. While focused mainly on the United States, international issues and perspectives are also considered.

Students explore the biosphere and its associated environments and ecosystems in the context of creating a model ecosystem, learning along the way about the animals and resources. Students investigate different types of ecosystems, learn new vocabulary, and consider why a solid understanding of one's environment and the interdependence of an ecosystem can inform the choices we make and the way we engineer our communities. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.
