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.

The digestive system is investigated in this learning activity to help participants learn how food is broken down and prepared for absorption, and list the components of the digestive system as well as their functions. Organs investigated include the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.

The digestive system is amazing: it takes the foods we eat and breaks them into smaller components that our body can use for energy, cell repair and growth. This lesson introduces students to the main parts of the digestive system and how they interact. In addition, students learn about some of the challenges astronauts face when trying to eat in outer space.

In this video we introduce the digestive system. We look at the two types of digestion: mechanical digestion and chemical digestion. We also look at the two subdivisions of the digestive system: the digestive tracts and the accessory structures.

"Digging for Fossils": A student laboratory activity

This lab activity is a paper fossil dig where students discover skeletal characteristics of humans, primates and hominids and are asked to make a short oral presentation to the class.

This is a study of the material life of information and its devices; of electronic waste in its physical and electronic incarnations; a cultural and material mapping of the spaces where electronics in the form of both hardware and information accumulate, break down, or are stowed away. Electronic waste occurs not just in the form of discarded computers but also as a scatter of information devices, software, and systems that are rendered obsolete and fail. Where other studies have addressed ""digital"" technology through a focus on its immateriality or virtual qualities, Gabrys traces the material, spatial, cultural, and political infrastructures that enable the emergence and dissolution of these technologies. In the course of her book, she explores five interrelated ""spaces"" where electronics fall apart: from Silicon Valley to Nasdaq, from containers bound for China to museums and archives that preserve obsolete electronics as cultural artifacts, to the landfill as material repository. All together, these sites stack up into a sedimentary record that forms the ""natural history"" of this study. Digital Rubbish: A Natural History of Electronics describes the materiality of electronics from a unique perspective, examining the multiple forms of waste that electronics create as evidence of the resources, labor, and imaginaries that are bundled into these machines. By drawing on the material analysis developed by Walter Benjamin, this natural history method allows for an inquiry into electronics that focuses neither on technological progression nor on great inventors but rather considers the ways in which electronic technologies fail and decay. Ranging across studies of media and technology, as well as environments, geography, and design, Jennifer Gabrys pulls together the far-reaching material and cultural processes that enable the making and breaking of these technologies.

An understanding of the microscale structure and composition of sedimentary rocks is of undiminished importance in diverse fields (e.g., microscale chemical analysis cannot proceed without petrography), yet the curriculum is no longer offering undergraduates the opportunity to develop sufficient expertise. In an effort to bolster the exposure of undergraduates to sedimentary petrology, the Tutorial Petrographic Image Atlas was created. The basic components of the tutorial are petrographic images that are viewed in a static mode (no rotation, no animation, no timed observation). Text boxes relating to identification of components within the image are attached to specific mapped regions of the image. Both the mapped regions and the text are invisible until the student points and clicks on an active region of the image. In essence, the student must 'ask', "What is that?" Information ranges from simple one word identifications to lengthy paragraphs explaining the finer points of why something is what it is.

This is a highly interactive digital product that attempts to recreate certain elements of the laboratory petrographic experience including: a sense of exploration; high-quality petrographic images; a visual field dominated by the image; multiple examples of features viewed in diverse contexts; rich content relating to the identification and significance of features; active, inquiry-based learning.

Unlike real-time laboratory experiences with the petrographic microscope, the digital tutorial can be used at any time and place that a computer is available, does not require the presence of a microscope or samples or an expert, can be viewed repeatedly, has the technical content integrated with the image, gives the student undivided "attention" (unlike the TA, it doesn't wander to the other side of the lab), and rarely gives answers unless "asked."

The purpose of this week's lab is to
- prepare calibration standards
- use a UV-Vis spectrometer to determine the spectral peaks for several dye solutions, and create a calibration curve
- calculate how much of each single-element standard solution is needed to make a multi-element stock solution

This is an online learning experience that transports learners around the world to different locations related to the Cretaceous -- Paleogene (K -- Pg) extinction event. Students will collect and analyze evidence to explain how natural events impact life on Earth.
The KPg extinction event, which occurred 66 mya, caused the mass extinction of nearly 75% of the plant and animal species on Earth, including the dinosaurs. It is marked by a thin layer of sediment which can be found throughout the world in marine and terrestrial rocks.

This activity illustrates the carbon cycle using an age-appropriate hook, and it includes thorough discussion and hands-on experimentation. Students learn about the geological (ancient) carbon cycle; they investigate the role of dinosaurs in the carbon cycle, and the eventual storage of carbon in the form of chalk. Students discover how the carbon cycle has been occurring for millions of years and is necessary for life on Earth. Finally, they may extend their knowledge to the concept of global warming and how engineers are working to understand the carbon cycle and reduce harmful carbon dioxide emissions.

Dr. Richard Butler speaks about heterodontosaurids, ornithischian dinosaurs, and new research into their breathing mechanisms.

Brian Engh, paleoartist, explains the process of paleoart and does a demonstration of creating a Stegosaurus. From skeleton to musculature to the possible colors of a Stegosaurus, follow along as Brian shows us what Sophie the Stegosaurus may have looked like. Warning Content Alert: This video contains brief discussion about dinosaur mating and may not be appropriate for all audiences.

In this classroom activity, middle school students explore the Greek and Latin root words used to create dinosaur names. The activity opens with background information for teachers about how dinosaurs are named. As a class, students explore the Greek and Latin roots of the words photograph, terrace and other familiar terms. Working individually, students complete a worksheet that challenges them to translate the meaning of seven dinosaurs' names. Then, working in pairs, students create their own dinosaur; name it; and describe how it moves, what it eats, how it raises it young, and how it behaves.
