Students act as if they are biological engineers following the steps of the engineering design process to design and create protein models to replace the defective proteins in a child’s body. Jumping off from a basic understanding of DNA and its transcription and translation processes, students learn about the many different proteins types and what happens if protein mutations occur. Then they focus on structural, transport and defense proteins during three challenges posed by the R&D; bio-engineering hypothetical scenario. Using common classroom supplies such as paper, tape and craft sticks, student pairs design, sketch, build, test and improve their own protein models to meet specific functional requirements: to strengthen bones (collagen), to capture oxygen molecules (hemoglobin) and to capture bacteria (antibody). By designing and testing physical models to accomplish certain functional requirements, students come to understand the relationship between protein structure and function. They graph and analyze the class data, then share and compare results across all teams to determine which models were the most successful. Includes a quiz, three worksheets and a reference sheet.
Every cell in your body needs to take in nutrients, oxygen, and raw materials and export wastes and other substances—but it’s not just a random traffic jam! A cell membrane (also called a plasma membrane) regulates what comes in and what goes out. Explore the properties of soap films and relate them to the properties of plasma membranes and the mechanics of transport across membranes.
By tracing the movement of radiation released during an accident at the Chernobyl nuclear power plant, students see how air pollution, like particulate matter, can become a global issue.

Students explore methods employing simple machines likely used in ancient pyramid building, as well as common modern-day material transportation. They learn about the wheel and axle as a means to transport materials from rock quarry to construction site. They also learn about different types and uses of a lever for purposes of transport. In an open-ended design activity, students choose from everyday materials to engineer a small-scale cart and lever system to convey pyramid-building materials.
Students are introduced to the structure, function and purpose of locks and dams, which involves an introduction to Pascal's law, water pressure and gravity.
The real structure of cell membrane is so dynamic & it not only allows the cells to move but also has constant movement & fluidity. Therefore, an animation would be great for teaching the dynamic movement of phospholipids & proteins in cell membrane. This LO also helps students to understand the movement of material across the membrane. I prefer students watch it at least twice.
In a class demonstration, students observe a simple water cycle model to better understand its role in pollutant transport. This activity shows one way in which pollution is affected by the water cycle; it simulates a point source of pollution in a lake and the resulting environmental consequences.
Infrastructures for energy, water, transport, information and communications services create the conditions for livability and economic development. They are the backbone of our society. Similar to our arteries and neural systems that sustain our human bodies, most people however take infrastructures for granted. That is, until they break down or service levels go down.
In many countries around the globe infrastructures are ageing. They require substantial investments to meet the challenges of increasing population, urbanization, resource scarcity, congestion, pollution, and so on. Infrastructures are vulnerable to extreme weather events, and therewith to climate change.
Technological innovations, such as new technologies to harvest renewable energy, are one part of the solution. The other part comes from infrastructure restructuring. Market design and regulation, for example, have a high impact on the functioning and performance of infrastructures.
Looking at models and maps, students explore different pathways and consequences of pollutant transport via the weather and water cycles. In an associated literacy activity, students develop skills of observation, recording and reporting as they follow the weather forecast and produce their own weather report for the class.

"New technologies for enhancing electronics and photonics are crucial for emerging applications in energy, sensing, artificial intelligence, and countless other areas. But these technologies are hard to come by using traditional semiconductors. Over the past decade, so-called third-generation semiconductors have proved to be a boon to materials science and engineering, giving researchers increased versatility in boosting device performance. Among the most promising properties of these materials is piezoelectricity—the ability to convert mechanical energy to electrical energy and vice versa. The December 2018 issue of the MRS Bulletin takes a look at how researchers are exploiting piezoelectricity in semiconductors to enhance electronic and photonic devices like never before, providing a glimpse into the world of piezotronics and piezo-phototronics. In 2006, Zhong Lin Wang’s group at Georgia Tech discovered that piezoelectricity in zinc oxide nanowires exerts a gating effect like that in transistors..."

Students learn that engineers develop different polymers to serve various functions and are introduced to selectively permeable membranes. In a warm-up activity, they construct models of selectively permeable membranes using common household materials, and are reminded about simple diffusion and passive transport. In the main activity, student pairs test and compare the selective permeability of everyday polymer materials engineered for food storage (including plastic grocery bags, zipper sandwich bags, and plastic wrap) with various in-solution molecules (iodine, corn starch, food coloring, marker dye), assess how the polymer’s permeability relates to its function/purpose, and compare that to the permeability of dialysis tubing (which simulates a cell membrane).
Working as if they were engineers, students design and construct model solar sails made of aluminum foil to move cardboard tube satellites through “space” on a string. Working in teams, they follow the engineering design thinking steps—empathize, define, ideate, prototype, test, redesign—to design and test small-scale solar sails for satellites and space probes. During the process, learn about Newton’s laws of motion and the transfer of energy from wave energy to mechanical energy. A student activity worksheet is provided.
Life in the city relies on the smooth operation of urban logistics. Everything from retail to services, construction to waste collection rely on an efficient and reliable freight transport system. However, with the increasing pressures of urbanization, this has to be balanced with the environmental and social impacts caused by transport activity. This is the challenge of City Logistics, a field of study that has significant practical implications for the world and the cities we live in. It is not merely a question of what is involved, but what can be done about urban freight transport to improve it for the sake of economic efficiency, quality of life, and sustainability.
From a systematic scientific foundation of the field, this course will take you on a journey to learn how city logistics is understood and practiced in cities around the world. Our instructors, members of a renowned global expert network, will teach you the basics of this highly complex social system. Using their experience in real-world projects, they will illustrate how the knowledge learnt in this course is applied across industry and the public sector.
This course caters primarily to university students or professionals working in urban transport infrastructure planning or logistics management.
