Students become familiar with the engineering design process as they design, build and test chair prototypes. The miniature chairs must be sturdy and functional enough to hold a wooden, hinged artist model or a floppy stuffed animal. They use their prototypes to assess design strengths and weaknesses.
Students are introduced to the "Walk the Line" challenge question. They write journal responses to the question and brainstorm what information they need to answer the question. Ideas are shared with the class (or in pairs and then to the class, if class size is large). Then students read an interview with an engineer to gain a professional perspective on linear data sets and best-fit lines. Students brainstorm for additional ideas and add them to the list. With the teacher's guidance, students organize the ideas into logical categories of needed knowledge.
Students teams use a laparoscopic surgical trainer to perform simple laparoscopic surgery tasks (dissections, sutures) using laparoscopic tools. Just like in the operating room, where the purpose is to perform surgery carefully and quickly to minimize patient trauma, students' surgery time and mistakes are observed and recorded to quantify their performances. They learn about the engineering component of surgery.
At its core, the LEGO MINDSTORMS(TM) NXT product provides a programmable microprocessor. Students use the NXT processor to simulate an experiment involving thousands of uniformly random points placed within a unit square. Using the underlying geometry of the experimental model, as well as the geometric definition of the constant π (pi), students form an empirical ratio of areas to estimate a numerical value of π. Although typically used for numerical integration of irregular shapes, in this activity, students use a Monte Carlo simulation to estimate a common but rather complex analytical form the numerical value of the most famous irrational number, π.
Learn about the Chandra X-Ray Observatory's telescope system, science instruments, and spacecraft system in this interactive activity adapted from NASA.
This lesson begins with an activity in which students induce EMF in a coil of wire using magnetic fields. Then, demonstrations on Eddy currents show how a magnetic field can slow magnets just as Eddy currents are used to slow large trains. There is then a demonstration in which a loop "jumps" because of a changing magnetic field. Finally, formal lecture reviews the cross product with respect to magnetic force and introduces magnetic flux, Faraday's law of Induction, Lenz's Law, Eddy currents, motional EMF and Induced EMF.
Can we change the blueprints of life? This week we are exploring that question with genetic engineering. We’ll discuss how selective breeding can improve agricultural practices, and the potential DNA-level engineering could have on other fields of engineering. We’ll also look at how optogenetics and CRISPR have opened up new ways for genetic engineers to change the DNA inside living cells.
A couple of homework problems from Chapter 2, Walking.
Students use balloons to perform several simple experiments to explore static electricity and charge polarization.
In this video we show you how to craft the chassis for the Bit-zee using a $3 piece of Lexan and tap light housing. Created by Karl Wendt.
This video shows how Bit-zee's shell was modified to allow space for the bumper switches. Created by Karl Wendt.
This lesson introduces the concepts of wavelength and amplitude in transverse waves. In the associated activity, students will use ropes and their bodies to investigate different wavelengths and amplitudes.
Engineering, like life, could really use a lot more cheese. This week we are looking at a cheese factory in Toronto and what it can teach us about process control systems. We’ll explore feedforward and feedback systems, and see how integrating them both with the final check of cascade control creates a system made to handle uncertainty the world throws its way.

Short Description:
Chemical Engineering Separations: A Handbook for Students is intended for use by undergraduate students who are taking a course in chemical engineering separations. The handbook assumes that students have taken one or two semesters of chemical engineering thermodynamics, one semester of heat and mass transfer, and one semester of computational methods for chemical engineering.
Long Description:
The purpose of this handbook is to introduce students to chemical engineering separations in a way that most closely aligns with what most entry-level chemical engineers will do in the workplace. Most newly hired chemical engineers will be responsible for monitoring and troubleshooting existing processes and proposing modifications to improve process performance. For this reason, we have written the handbook to emphasize how to optimize process conditions, how to retrofit an existing unit to meet a given separation objective while not exceeding operating capacity, or how to select the best existing or pre-fabricated unit to meet a separation objective while maintaining safe operation at a reasonable cost.

This course aims to connect the principles, concepts, and laws/postulates of classical and statistical thermodynamics to applications that require quantitative knowledge of thermodynamic properties from a macroscopic to a molecular level. It covers their basic postulates of classical thermodynamics and their application to transient open and closed systems, criteria of stability and equilibria, as well as constitutive property models of pure materials and mixtures emphasizing molecular-level effects using the formalism of statistical mechanics. Phase and chemical equilibria of multicomponent systems are covered. Applications are emphasized through extensive problem work relating to practical cases.
This is an undergraduate introductory laboratory subject in ocean chemistry and measurement. There are three main elements to the course: oceanic chemical sampling and analysis, instrumentation development for the ocean environment, and the larger field of ocean science.
This course is offered through The MIT/WHOI Joint Program. The MIT/WHOI Joint Program is one of the premier marine science graduate programs in the world. It draws on the complementary strengths and approaches of two great institutions: the Massachusetts Institute of Technology (MIT) and the Woods Hole Oceanographic Institution (WHOI).
