In this lesson, students will investigate error. As shown in earlier activities from navigation lessons 1 through 3, without an understanding of how errors can affect your position, you cannot navigate well. Introducing accuracy and precision will develop these concepts further. Also, students will learn how computers can help in navigation. Often, the calculations needed to navigate accurately are time consuming and complex. By using the power of computers to do calculations and repetitive tasks, one can quickly see how changing parameters likes angles and distances and introducing errors will affect their overall result.

This case examines the integrated physiological response to dehydration and starvation from the real-life report of a girl discovered 15 days after an earthquake devastated Port Au-Prince, Haiti, in January 2010. From the meager scientifically relevant facts reported by the newspaper accounts of the girl's condition, students are asked to work through the pathways of water loss from dehydration as they examine the multiple systems involved in homeostatic responses, and then are asked to calculate whether it is possible for a human to withstand 15 days without water. The case also gives the instructor the opportunity to differentiate between the general adaptive response to a stressor and the specialized adaptive responses exhibited by well-acclimated natives. The case was designed for an upper division comparative or human physiology course or possibly a graduate level medical physiology course.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes. By observing these changes, learners show that dark materials absorb and reemit the energy contained in light more readily than light-colored materials. Learners can also distinguish energy absorbed and reemited by radiation, convection, and conduction by comparing the behavior of black, white, and silver objects. This resource guide includes detailed explanation of the phenomenon and background information about liquid crystals.

This "clicker case" begins by assessing students' impressions of global climate change and the role that human activities play in recent global warming trends. Students assume the role of an intern working for a U.S. senator. They need to understand the scientific evidence for human impact on climate change so that they can advise the senator on future policy decisions. The case was designed for use in a one-semester introductory biology course taken primarily by freshmen and sophomores to fulfill a general education requirement, but could be used in any introductory biology course or in an ecology or environmental science course. It consists of a PowerPoint presentation (~1.6MB) presented in class that is punctuated by multiple-choice questions students respond to using personal response systems ("clickers"). The case can be adapted for use without these technologies.

This "clicker case" is a continuation of another case in our collection, "Global Climate Change: Evidence and Causes," in which students assumed the role of an intern working for a U.S. senator so that they could advise the senator on future policy decisions. In this case, students learn about the impact and effects of global climate change as well as technologies and practices available to remediate the impact of climate effects. The case was designed for use in a one-semester introductory biology course taken primarily by freshmen and sophomores to fulfill a general education requirement, but could be used in any introductory biology course or in an ecology or environmental science course. It consists of a PowerPoint presentation (~2.2MB) presented in class that is punctuated by multiple-choice questions students respond to using personal response systems, or "clickers." The case can be adapted for use without these technologies.

Students use graph theory to create social graphs for their own social networks and apply what learn to create a graph representing the social dynamics found in a dramatic text. Students then derive meaning based on what they know about the text from the graphs they created. Students learn graph theory vocabulary, as well as engineering applications of graph theory.

Students analyze their social networks using graph theory. They gather data on their own social relationships, either from Facebook interactions or the interactions they have throughout the course of a day, recording it in Microsoft Excel and using Cytoscape (a free, downloadable application) to generate social network graphs that visually illustrate the key persons (nodes) and connections between them (edges). The nodes in the Cytoscape graphs are color-coded and sized according to the importance of the node (in this activity, nodes are people in students' social networks). After the analysis, the graphs are further examined to see what can be learned from the visual representation. Students gain practice with graph theory vocabulary, including node, edge, betweeness centrality and degree on interaction, and learn about a range of engineering applications of graph theory.

This PowerPoint case (~2.4 MB) was developed for an undergraduate, non-majors course in conservation biology. It explores the controversy surrounding land purchases in the Patagonia region of Chile and Argentina. According to local indigenous peoples, wealthy individuals are purchasing their ancestral land and then forcing them to leave. Individual landowners and international environmental groups wish to preserve the pristine ecosystems that remain in Patagonia. This case serves as an introduction to stakeholder controversy, the international dimensions of environmental policy, public versus private ownership for environmental protection, and conflict resolution.

This activity requires students to design an experiment to determine the best conditions for growing crystals. Students then are asked to conclude what the ideal conditions may be, how this information is useful, and who may want to know it. It is a great way to continue using scientific process skills within a Geology unit.

The marine environment is unique and requires technologies that can use sound to gather information since there is little light underwater. The sea-floor is characterized using underwater sound and acoustical systems. Current technological innovations are allowing scientists to further understand and apply information about animal locations and habitat. Remote sensing and exploration with underwater vehicles allows scientists to map and understand the sea floor, and in some cases, the water column. In this lesson, the students will be shown benthic habitat images produced by GIS. These imaged will lead to a class discussion on why habitat mapping is useful and how current technology works to make bathymetry mapping possible. The teacher will then ask inquiry-based questions to have students brainstorm about the importance of bathymetry mapping.
