To reinforce students' understanding of the human digestion process, the functions of several stomach and small intestine fluids are analyzed, and the concept of simulation is introduced through a short, introductory demonstration of how these fluids work. Students learn what simulation means and how it relates to the engineering process, particularly in biomedical engineering. The teacher demo requires vinegar, baking soda, water and aspirin.

This course will guide graduate students through the process of using rapid prototyping and CAD/CAM devices in a studio environment. The class has a theoretical focus on machine use within the process of design. Each student is expected to have completed one graduate level of design computing with a full understanding of solid modeling in CAD. Students are also expected to have completed at least one graduate design studio.

In this activity, students investigate different methods (aeration and filtering) for removing pollutants from water. They will design and build their own water filters.

This activity is a field investigation where students will observe three areas with high sensitivity to pollution, and test water quality in two of the locations.

In this quantitative field activity, students collect field data on channel geometry, flow velocity, and bed materials. Using these data, they apply flow resistance equations and sediment transport relations to estimate the bankfull discharge and to determine if the flow is sufficient to mobilize the bed.

Watershed Awareness using Technology and Environmental Research for Sustainability (WATERS)

The WATERS project is developing and researching a student-centered, place-based, and accessible curriculum for teaching watershed concepts and water career awareness for students in the middle grades. This 10-lesson unit includes online, classroom, and field activities. Students use a professional-grade online GIS modeling resource, simulations, sensors, and other interactive resources to collect environmental data and analyze their local watershed issues. The WATERS project is paving a path to increased access to research-based, open access curricula that hold the potential to significantly increase awareness of and engagement with watershed concepts and career pathways in learners nationwide.

I find that when assigning lengthy readings for in-class discussion, it is extremely helpful to guide students' preparation with specific questions, and incorporate these in worksheets that explicitly call for students to write out their responses before entering the classroom. These worksheets can provide some added structure for whole-class discussion, or can provide a specific agenda for review of the readings in small groups. Because these readings are more than a few years old, I have also found it useful to assign small groups of students to give brief reports that expand on and update the issues raised in the readings.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Microbial interactions play a crucial role in the functioning and biogeochemical cycling of Earth's ecosystem. But these connections are highly dynamic and poorly understood. A clear picture of how microbes interact over time could help gain insight into processes that influence nutrient cycling, productivity, and the overall health of marine ecosystems. Researchers investigated microbial dynamics in the Mediterranean Sea on a monthly basis over 10 years. To pinpoint persistent, seasonal, and temporary microbial associations, the researchers identified a temporal network capturing the interactomes of each sample. This network followed an annual cycle that collapsed and reassembled with changes in water temperature. And microbial associations were more repeatable in colder versus warmer months. However, only 16 associations could be validated in the literature, underlining a serious knowledge gap in marine microbial ecological interactions..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

The cartoonist mocks the opportunism evident in Winfield Scott's endorsement of both the abolitionist cause and the Missouri Compromise. Scott, in military uniform, is seated at a table with a plate of soup before him. He lifts his spoon from the plate and finds in it a kneeling black man, with arms outstretched saying, "Dis poor nigger am like Jonah, when de men would'nt let him stay in de Ship; and de whale would'nt let him stay in de water." Scott observes, "Here's a predicament! first I shall have to swallow this nigger to please the north & then take a compromise emetic and deliver him up to please the south. Faugh! what a dose of Ginger, but I am anxious to serve the country at $25,000 pr Annum so down he goes." Appearing from out of the steam is a Southern planter who remarks, "I should think from the flavor of the Generals last plate of Soup that my darkey had tumbled into it. I've heard of 'Green Turtle' and 'Mock Turtle' but that would be a pretty Strong dish of 'Black Turtle." For the origin of the perennial joke about Scott's "hasty plate of soup," see "Distinguished Military Operations" (no. 1846-15). The style of "A Dish of Black Turtle" is similar to that of John L. Magee's "A Magnificent Offer to a Magnificent Officer" (no. 1852-27), and is probably by the same artist.|For sale No. 2 Spruce St. N.Y.|Probably drawn by John L. Magee.|Pub. by P.

This task asks students to find a linear function that models something in the real world. After finding the equation of the linear relationship between the depth of the water and the distance across the channel, students have to verbalize the meaning of the slope and intercept of the line in the context of this situation.

Through a teacher-led discussion, students realize that the food energy plants obtain comes from sunlight via the plant process of photosynthesis. They learn what photosynthesis is, at an age-appropriate level of detail and vocabulary, and then begin to question how we know that photosynthesis occurs, if we can't see it happening. Elodea is a common water plant that students can use to directly observe evidence of photosynthesis. When Elodea is placed in a glass beaker near a good light source, bubbles of oxygen will be released as products of photosynthesis. By counting the number of bubbles that rise to the surface in a five-minute period, students can compare the photosynthetic activity of Elodea in the presence of high and low light levels.

This activity is a guided inquiry where students will investigate if water molecules have any space between them.

Students work with specified materials to create aqueduct components that can transport two liters of water across a short distance in their classroom. The design challenge is to create an aqueduct that can supply Aqueductis, a (hypothetical) Roman city, with clean water for private homes, public baths and fountains as well as crop irrigation.

Students gain a basic understanding of the properties of media soil, sand, compost, gravel and how these materials affect the movement of water (infiltration/percolation) into and below the surface of the ground. They learn about permeability, porosity, particle size, surface area, capillary action, storage capacity and field capacity, and how the characteristics of the materials that compose the media layer ultimately affect the recharging of groundwater tables. They test each type of material, determining storage capacity, field capacity and infiltration rates, seeing the effect of media size on infiltration rate and storage. Then teams apply the testing results to the design their own material mixes that best meet the design requirements. To conclude, they talk about how engineers apply what students learned in the activity about the infiltration rates of different soil materials to the design of stormwater management systems.

Jim O'Toole, senior fellow in business ethics, Markkula Center for Applied Ethics, interviews Carson Block, research director, Muddywaters, (a company whose name is taken from Chinese proverb - "Muddy waters make it easy to catch fish.") Block handles fraudulent companies and investigations, and his business focuses primarily on Chinese companies doing business in the U.S. His business model - not without controversy- is to short sell company stock for businesses on the brink. The company's reports and research are released to the public. Many companies, including those in China, can appear too good to be true, and they often are. On the other hand, investors need to take responsibility for their investments.

How does infrastructure meet our needs? What happens when we are cut off from that supporting infrastructure? As a class, students brainstorm, identify and explore the pathways where their food, water and energy originate, and where wastewater and solid waste go. After creating a diagram that maps a neighborhood's inputs and waste outputs, closed and open system concepts are introduced by imagining the neighborhood enclosed in a giant dome, cut off from its infrastructure systems. Students consider the implications and the importance of sustainable resource and waste management. They learn that resources are interdependent and that recycling wastes into resources is key to sustain a closed system.

This resource has students role-play an Indigenous climate summit. It includes handouts about each Indigenous group and their concerns about climate change.

Students see how surface tension can enable light objects (paper clips, peppercorns) to float on an island of oil in water, and subsequently sink when the surface tension of the oil/water interface is reduced by the addition of a surfactant; such as ordinary dish soap.
