All animals develop and grow over time. The animals in this video segment, however, undergo very dramatic changes on their way to adulthood -- a developmental process known as metamorphosis.

What is a city? What shapes it? How does its history influence future development? How do physical form and institutions vary from city to city and how are these differences significant? How are cities changing and what is their future? This course will explore these and other questions, with emphasis upon twentieth-century American cities. A major focus will be on the physical form of cities—from downtown and inner-city to suburb and edge city—and the processes that shape them.

These questions and more are explored through lectures, readings, workshops, field trips, and analysis of particular places, with the city itself as a primary text. In light of the 2016 centennial of MIT’s move from Boston to Cambridge, the 2015 iteration of the course focused on MIT’s original campus in Boston’s Back Bay, and the university’s current neighborhood in Cambridge. Short field assignments, culminating in a final project, will provide students opportunities to use, develop, and refine new skills in “reading” the city.

This article assembles free resources from the Polar Plants issue of the Beyond Penguins and Polar Bears cyberzine into a unit outline based on the 5E learning cycle framework. Outlines are provided for Grades K-2 and 3-5.

Using Avida-ED freeware, students control a few factors in an environment populated with digital organisms, and then compare how changing these factors affects population growth. They experiment by altering the environment size (similar to what is called carrying capacity, the maximum population size that an environment can normally sustain), the initial organism gestation rate, and the availability of resources. How systems function often depends on many different factors. By altering these factors one at a time, and observing the results, students are able to clearly see the effect of each one.

These discussion guides for Psychology present videos or readings for students to evaluate, compare, and respond to. Suitable for individual or group use, they include learning objectives, discussion questions, and evaluation tables. The guides cover Emerging Adulthood, Enhancing Memory, Schizophrenia, and Growth Mindset. The authors also provide a template for the creation of additional guides.

The Discussion Guides were authored by:

Students see and learn how crystallization and inhibition occur by making sugar crystals with and without additives in a supersaturation solution, testing to see how the additives may alter crystallization, such as by improving crystal growth by more or larger crystals. After three days, students analyze the differences between the control crystals and those grown with additives, researching and attempting to deduce why certain additives blocked crystallization, showed no change or improved growth. Students relate what they learn from the rock candy experimentation to engineering drug researchers who design medicines for targeted purposes in the human body. Conduct the first half of this activity one day before presenting the associated lesson, Body Full of Crystals. Then conduct the second half of the activity.
