Squeak is a modern open-source development environment for the classic Smalltalk-80 programming language. Despite being the first purely object-oriented language and environment, Smalltalk is in many ways still far ahead of its successors in promoting a vision of an environment where everything is an object, and anything can change at run-time.

Through hands-on group projects, students learn about the force of compression and how it acts on structural components. Using everyday materials, such as paper, toothpicks and tape, they construct structures designed to (hopefully) support the weight of a cinder block for 30 seconds.

Students analyze and begin to design a pyramid. Working in engineering teams, they perform calculations to determine the area of the pyramid base, stone block volumes, and the number of blocks required for their pyramid base. They make a scaled drawing of the pyramid using graph paper.

To get a better understanding of complex networks, students create their own, real social network example by interacting with their peers in the classroom and documenting the interactions. They represent the interaction data as a graph, calculate two mathematical quantities associated with the graph—the degree of each node and the degree distribution of the graph—and analyze how these quantities can be used to infer properties of the social network at hand.

Students act as chemical engineers and use LEGO® MINDSTORMS® NXT robotics to record temperatures and learn about the three states of matter. Properties of matter can be measured in various ways, including volume, mass, density and temperature. Students measure the temperature of water in its solid state (ice) as it is melted and then evaporated.

This hands-on activity explores the concept of static electricity. Students attract an O-shaped piece of cereal to a charged comb and watch the cereal jump away when it touches the comb. Students also observe Styrofoam pellets pulling towards a charged comb, then leaping back to the table.

Statica is de leer van mechanisch evenwicht.
Een lichaam beweegt niet (of is in een éénparige rechtlijnige beweging) als de som van de krachten die op dat lichaam werken nul is. Als ook de som van de momenten die op dat lichaam werken nul is, dan roteert het lichaam ook niet. De consequentie van deze twee evenwichtsvoorwaarden (som van krachten =0 en som van momenten =0), is dat voor een lichaam waarop een aantal bekende krachten werken de (onbekende) reactiekrachten bepaald kunnen worden . Dit is van groot belang omdat de grootte van de reactiekrachten de dimensionering en materiaalkeuze van toe te passen componenten bepalen. Binnen het vak “Statica” wordt in detail ingegaan op de verschillende mechanische belastingen, vaak voorkomende constructies en hoe te rekenen met de diverse belastingen.

Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. While learning how a magnifying glass works, students see how the orientation of an image changes with the distance of the lens from its focal point. They also discover how a prism works by refracting light and making rainbows. And, students investigate the polar nature of light using sunglasses and polarized light film.
Students learn about the strength of bones and methods of helping to …
Students learn about the strength of bones and methods of helping to mend fractured bones. During a class demonstration, a chicken bone is broken by applying a load until it reaches a point of failure (fracture). Then, working as biomedical engineers, students teams design their own splint or cast to help repair a fractured bone, learning about the strength of materials used.

Fundamentals of detection and estimation for signal processing, communications, and control. Vector spaces of random variables. Bayesian and Neyman-Pearson hypothesis testing. Bayesian and nonrandom parameter estimation. Minimum-variance unbiased estimators and the Cramer-Rao bounds. Representations for stochastic processes; shaping and whitening filters; Karhunen-Loeve expansions. Detection and estimation from waveform observations. Advanced topics: linear prediction and spectral estimation; Wiener and Kalman filters.

Students engineer a working pair of shin guards for soccer or similar contact sport from everyday materials. Since many factors go into the design of a shin guard, students follow the Engineering Design Process to create a prototype. Along the way, students keep a notebook documenting each stage of the process and reflect on what their learned during the design.

Students learn about composite materials, tension as a force and how they act on structural components through the design and testing of strips of plastic chair webbing.

Students work through an online tutorial on MIT's App Inventor to learn how to create Android applications. Using those skills, they create their own applications and use them to collect data from an Android device accelerometer and store that data to databases. NOTE: Teachers and students must have a working knowledge of basic programming and App Inventor to complete this lesson. This lesson is not an introduction to MIT's App Inventor and is not recommended for use without prior knowledge of App Inventor to produce an end product. This lesson is an application for App Inventor that allows for the storage of persistent data (data that remains in memory even if an app is closed). This required prior knowledge can come from other experiences with the App Inventor. Also, many additional resources are available, such as tutorials from MIT. This lesson could also be used as an enrichment project for students who are self-motivated to learn the App Inventor software.

Students learn that wind and storms can form at the boundaries of interacting high and low pressure air masses. They learn the distinguishing features of the four main types of weather fronts (warm fronts, cold fronts, stationary fronts and occluded fronts) and how those fronts are depicted on a surface weather analysis, or weather map. Students also learn several different ways that engineers help with storm prediction, analysis and protection.

12.103 explores the role of scientific knowledge, discovery, method, and argument in environmental policymaking from both idealistic and realistic perspectives. The course will use case studies of science-intensive environmental controversies to study how science was used and abused in the policymaking process. Case studies include: global warming, biodiversity loss, and nuclear waste disposal siting. Subject includes intensive practice in the writing and presentation of "position statements" on environmental science issues.

Examines the fundamental concepts of strategic planning and management in the context of the real estate, design, and construction industry. Discusses the basic business relationships among firms in the design and construction value chain. Specific topics include: industry analysis; strategic planning models; information technology strategy; strategy in fragmented industries; negotiation; and macro trends shaping the industry as a whole. Case method of instruction is used, and supplemented by extensive readings. From the course home page: This course provides an overview of key concepts in strategic management in the construction, real estate, and architecture industries. Topics include supply chain analysis, market segmentation, vertical integration, competitive advantage, and industry transformation. This course is of interest to students seeking more understanding of the business dynamics of real estate and construction; seeking to provide value in firms which they may join; or seeking to build a foundation for their own entrepreneurial pursuits.

Working as engineering teams, students design and create model beam bridges using plastic drinking straws and tape as their construction materials. Their goal is to build the strongest bridge with a truss pattern of their own design, while meeting the design criteria and constraints. They experiment with different geometric shapes and determine how shapes affect the strength of materials. Let the competition begin!
