Cultivating stakeholders is a critical part of event management. This application activity covers the following four-stage process for involving stakeholders in an event: identification of stakeholders, classifying stakeholders, assessing stakeholders, and maintaining stakeholders. A case study is provided for students to apply to cultivating stakeholders in an industry example.
In the market segmentation of festival attendees application activity, students will review a mini-lecture material related to market segmentation, target marketing, and event positioning. Students will then apply the concepts of marketing segmentation, target marketing, and event positioning by analyzing data collected from an international music festival to establish the target market of the international music festival.
Risk management is a critical part of event management. This worksheet covers definitions of the key aspects of risk management and the steps taken by event management in creating a risk management plan. A case study is provided for students to apply the risk management process in an industry example.
Sponsorship management is activities that an event organization engages in to secure support from sponsors and manage the interests of sponsors at the event. The organizer and sponsor are jointly interested in successfully operating events for their mutual benefit. This section provides an overview of sponsorship management for events. The differences between sponsorship and advertising were compared for their strengths and weaknesses. The sponsorship management of a social event was discussed from the prospective from the perspective of organizers and sponsors. A case study on an LGBT+ event provided a case problem for how to construct a social media sponsorship package.
Students learn that economic forces have an impact beyond the financial world. First, they learn that Progressive Era public health reforms inspired a commercial response to the growing demand for sanitation through the rapid increase in bathroom-fixture production. Students then use FRED, economic data from Federal Reserve Bank of St. Louis, to analyze how bathroom-fixture production changed throughout the 1920s. They examine primary documents—1920s advertising—to see how companies fused the Progressive Era with the new consumer culture. Finally, students complete the lesson by responding to AP U.S. History-style short-answer questions.
The Evidence Based Medicine (EBM) Guide is designed to assist health care professionals and students become effective and efficient users of the medical literature. The guide provides an introduction to EBM and its core concepts. Topics include Levels of Evidence, Asking Clinical Questions, Searching PubMed, Clinical Filters, Additional Searching Techniques, Search Examples, Appraisal, and Pre-Appraised Summaries.
In this activity, students make and manipulate physical shoreline models to discover the features of resilient shorelines and to critically evaluate the impacts of rising seas. Students will use NOAA's Sea Level Rise Viewer to observe a coastal area of interest and predict the consequences of sea level rise on people, the environment, and the economy. Though the curriculum references North Carolina, this lesson will work for all coastal areas.
The lump of labor fallacy holds that there is a fixed amount of work to be done, which determines the number of jobs in an economy. If this were true, new jobs could not be generated, just reallocated. This essay provides some clear thinking about the role of labor in an economy.

In this unit, students wonder about the physical drivers of ocean movement, explore density differences, and take a look at some tiny creatures who struggle to keep their place in the water column in the midst of all that ocean motion.
Each unit of the Explore the Salish Sea curriculum contains a detailed unit plan, a slideshow, student journal, and assessments. All elements are adaptable and can be tailored to your local community.
In this unit, students will solve a mystery about changes in oyster larvae in the Salish Sea, causing oyster farmers to send their larvae to Hawaii until they grow stronger. They will look for clues in:
• activities and games, articles, and films that introduce the concepts of habitat and ecosystem
• structures and behaviors for survival in intertidal zone habitats
• the Earth-moon-sun interactions that drive the tides
• the importance of First Foods of the intertidal to first nations communities;
• how intertidal organisms interact across the Salish Sea food web
Afterward, they will arrive at the importance of a balanced carbon cycle in the health of the ocean and use a full scientific investigation to test if their local waters have a healthy pH for oyster larvae and other shelled creatures. Clear pathways of hope are woven into this complex issue, so students know that scientists and leaders are working to solve this problem - and kids can help!
In this activity, students use authentic Arctic climate data to explore albedo and its relationship to seasonal snowmelt as a self-reinforcing feedback mechanism, which is then applied to large scale global climate change.
Through this lesson and its series of hands-on mini-activities, students answer the question: How can we investigate and measure the inside of an object or its structure if we cannot take it apart? Unlike the destructive nuclear weapon test (!), nondestructive evaluation (NDE) methods are able to accomplish this. After an introductory slide presentation, small groups rotate through five mini-activity stations: 1) applying Maxwell’s equations, 2) generating currents, 3) creating magnetic fields, 4) solving a system of equations, and 5) understanding why the finite element method (FEM) is important. Through the short experiments, students become familiar with the science and physics being used and make the mathematical connections. They explore components of NDE and see how engineers find unseen flaws and cracks in materials that make aircraft. A pre/post quiz, slide presentation and worksheet are included.
This activity introduces students to the Arctic and Arctic climate. Through a virtual exploration of the geography of the Arctic students become familiar with the region. They are then introduced to meteorological parameters that Arctic research teams use.
This is an activity about the solar activity cycle. Learners will construct a graph to identify a pattern of the number of observed sunspots and the number of coronal mass ejections emitted by the Sun over a fifteen year time span. A graphing calculator is recommended, but not required, for this activity. This is the second activity in the Solar Storms and You: Exploring the Wind from the Sun educator guide.
This video explores what scientists know about how changes in global climate and increasing temperatures affect different extreme weather events.
Introduction to extreme shots and angles.
