This lesson focuses on the process of pollination. The learning objectives include learning the anatomy and physiology of flowers, the ecology of pollination, and a focus on plants as essential players in the natural world. There are no prerequisites for the lesson. The lesson will take 1½ hours, or 2 class periods or more -- depending on the areas teachers want to spend more time on or how far in depth they want their students to go. Materials needed are colored modeling clay, 8 or more assorted fresh flowers or pictures of flowers, preferably native to the local ecosystem. Dissecting microscopes or magnifying glasses are great for examining the fresh flowers, but not necessary. Additionally, pictures of different subjects/objects amongst plants are needed for the last activity. Activities for the breaks include assessing student knowledge of flowers by model building, and examining flowers to determine and distinguish between the pollination anatomy of different flowers.

Microeconomics with Ethics is an introductory college-level textbook that will enable students to understand current controversies about how to best organize an economic system. The approach emphasizes economic model development and how to interpret their results. The textbook first introduces an Edgeworth box to explain the gains from trade and comparative advantage. We then introduce market complexity, stepwise, by introducing monopoly, oligopoly, and finally perfect competition with supply and demand. Government policy is analyzed under perfect competition and in the presence of market imperfections such as externalities, public goods and common resources. Students will learn why some economic models support limited government while others support a much larger role for government. The textbook diverges only slightly from traditional neoclassical textbooks by demonstrating why individual self-interest must be constrained by ethical behavior to achieve economically efficient outcomes. For example, the acceptance of theft, equivalent to a violation of property rights, may more readily satisfy someone’s self-interest, but would nonetheless undermine the development of markets involving mutually voluntary exchange. Other unethical behaviors examined include deceptive business practices, efforts to undermine free competition, the unwillingness to consider community well-being, and economic disloyalties. Lastly, the text highlights how both private institutions, such as religions, and public institutions, such as criminal justice systems, can constrain unethical behaviors and thereby promote economic efficiency. Students will come away from this course with a rich understanding of the modern economic system and a clearer perspective on the different opinions across the economic and political spectrum about how to best organize an economy.

Introduces the major concepts and principles of public health and the determinants of health status in communities. Emphasizes the ecological model that focuses on the linkages and relationships among multiple natural and social determinants affecting health. Course may be offered online.

Doctoral level seminar in system dynamics modeling with a focus on social, economic and technical systems. The course covers classic works in dynamic modeling from various disciplines and current research problems and papers. Participants critique theories and models, often including replication, testing, and improvement of various models.

This Mini Lecture explores the smallest building blocks of matter. It introduces to Muray Gell-Man’s quark model, the Higgs mechanism named after British physicist Peter Higgs as well as the experiments done at the research center CERN.

Statistical thinking is a way of understanding a complex world by describing it in relatively simple terms that nonetheless capture essential aspects of its structure, and that also provide us some idea of how uncertain we are about our knowledge. The foundations of statistical thinking come primarily from mathematics and statistics, but also from computer science, psychology, and other fields of study.

Students build a model of the Sun-Earth-Moon system, exploring how the Moon revolves around the Earth, and the Earth around the Sun. Students play a memory game and learn some characteristics about the three objects.

This course presents a comparison of different proposed architectures for the syntax module of grammar. The subject traces several themes across a wide variety of approaches, with emphasis on testable differences among models. Models discussed include ancient and medieval proposals, structuralism, early generative grammar, generative semantics, government-binding theory/minimalism, LFG, HPSG, TAG, functionalist perspectives and others.

Continuation of 15.871, emphasizing tools and methods needed to apply systems thinking and simulation modeling successfully in complex real-world settings. Uses simulation models, management flight simulators, and case studies to deepen the conceptual and modeling skills introduced in 15.871. Through models and case studies of successful applications students learn how to use qualitative and quantitative data to formulate and test models, and how to work effectively with senior executives to implement change successfully.

This course provides a series of strategic frameworks for managing high-technology businesses. The emphasis throughout the course is on the development and application of conceptual models which clarify the interactions between competition, patterns of technological and market change, and the structure and development of organizational capabilities.
This is not a course in how to manage product or process development. The main focus is on the acquisition of a set of powerful analytical tools which are critical for the development of a technology strategy as an integral part of business strategy. These tools can provide the framework for deciding which technologies to invest in, how to structure those investments and how to anticipate and respond to the behavior of competitors, suppliers, and customers. The course should be of particular interest to those interested in managing a business for which technology is likely to play a major role, and to those interested in consulting or venture capital.

There is a 40% chance that the lower ⅓ of the of the Cascadia subduction zone will rupture in the next 50 years, generating a large earthquake and ensuing tsunami. In this project, students will work collaboratively to design and test a model of a vertical evacuation structure. They will evaluate the performance of their models and propose further modifications to improve their design. Students will then make a scale drawing and a model to apply math concepts of scale to designing and creating an ideal model of a vertical evacuation structure. Finally, students will present their findings and proposed final design to their peers and an adult audience. The entire process takes about 2 weeks, and was expanded to include more information and activities with earthquake/tsunami prediction and application of scale. The unit is a great fit for standards within Earth Science (specifically plate tectonics and human mitigation) as well as Engineering and Design standards.

The basic objective of Unified Engineering is to give a solid understanding of the fundamental disciplines of aerospace engineering, as well as their interrelationships and applications. These disciplines are Materials and Structures (M); Computers and Programming (C); Fluid Mechanics (F); Thermodynamics (T); Propulsion (P); and Signals and Systems (S). In choosing to teach these subjects in a unified manner, the instructors seek to explain the common intellectual threads in these disciplines, as well as their combined application to solve engineering Systems Problems (SP). Throughout the year, the instructors emphasize the connections among the disciplines.

Students explore the increase in atmospheric carbon dioxide over the past 40 years with an interactive online model. They use the model and observations to estimate present emission rates and emission growth rates. The model is then used to estimate future levels of carbon dioxide using different future emission scenarios. These different scenarios are then linked by students to climate model predictions also used by the Intergovernmental Panel on Climate Change.

This activity is a hands-on guided inquiry activity designed to highlight the role of an ice shelf on slowing the movement of continental ice sheets in Antarctica. Students build a model of Antarctica and both continental glaciers and ice shelves using paper models of the land and slime for glaciers and ice. Students use their model to explore the impact of recent and potential ice shelf melting and break-up.

Every step we take is in a watershed. Let's learn more about them! Check out the Stream Restoration Coordinator video to learn how scientists help improve stream health. Then, in the Discovery Challenge video, observe, investigate, and record information about your watershed from a distance and then really close up . Then, after learning a little more about watersheds, we will create models of watersheds and use those models to investigate how soil and chemicals might move through our watersheds.
