Magnetic Resonance Imaging
This lesson ties the preceding lessons together and brings students back to the grand challenge question on MRI safety. During this lesson, students focus on the logistics of magnetic resonance imaging as well as the MRI hardware. Students can then integrate this knowledge with their acquired knowledge on magnetic fields to solve the challenge question.
This lesson discusses solenoids. Students learn how to calculate the magnetic field along the axis of a solenoid and complete an activity exploring the magnetic field of a metal slinky. Solenoids form the basis for the magnet of an MRI. Exploring the properties of this solenoid helps students understand the MRI machine.
Thrown for a Loop
In this lesson, students begin to focus on the torque associated with a current carrying loop in a magnetic field. Students are prompted with example problems and use diagrams to visualize the vector product. In addition, students learn to calculate the energy of this loop in the magnetic field. Several example problems are included and completed as a class. A homework assignment is also attached as a means of student assessment.
Cuttlefish have the ability to change their skin coloring and pattern to match their surroundings. The cuttlefish uses this ability to camouflage, or hide, itself against its background and also to communicate with other ocean dwellers.

Gauguin, Cézanne, Matisse: Visions of Arcadia
June 20, 2012 - September 3, 2012: The theme of an earthly paradise, or Arcadia, has been popular in theater, poetry, music, and art since antiquity. This exhibition explores the theme in three such paintings of the time: Paul Gauguin’s Where Do We Come From? What Are We? Where Are We Going? (1898), Paul Cézanne’s The Large Bathers (1906), and Henri Matisse’s Bathers by a River (1909-17).

21L.448J Darwin and Design (MIT)
Humans are social animals; social demands, both cooperative and competitive, structure our development, our brain and our mind. This course covers social development, social behaviour, social cognition and social neuroscience, in both human and non-human social animals. Topics include altruism, empathy, communication, theory of mind, aggression, power, groups, mating, and morality. Methods include evolutionary biology, neuroscience, cognitive science, social psychology and anthropology.
Koch's Crickets: A Study in Etiology
Students apply Koch's Postulates in an attempt to discover the causative agent of "Pink Plague" a disease that has struck a group of commercially raised crickets. During the course of this exercise the students will isolate the suspected pathogen from one of a group of infected crickets. They will then characterize the isolated organism and use it to infect a new group of crickets to see if they can reproduce the same symptoms in the newly infected group. Reisolation of the suspected pathogen fr
Shimi: Georgia Tech's New Robotic Musician
Shimi, a musical companion developed by Georgia Tech's Center for Music Technology, recommends songs, dances to the beat and keeps the music pumping based on listener feedback. The smartphone-enabled, one-foot-tall robot is billed as an interactive "musical buddy." For more information, visit http://www.gatech.edu/newsroom/release.html?nid=137351 and http://tovbot.com/.
Introductions to Equations with Uncommon Denominators
In this pre-algreba tutorial video, students will learn how to solve equations with uncommon denominators. This is a great resource to introduce and/or to re-teach this important skill in the classroom. (2:48)

Light-Induced Phenotypic Plasticity in Plants
Phenotypic plasticity is the ability of an individual organism to alter its physiology or morphology in response to changes in environmental conditions. This ability is particularly important for the non-motile vascular plants that are unable to move when environmental conditions become unfavourable. This exercise compares morphological and anatomical characteristics of two plant species after 6 weeks of growth under two differing levels of irradiation. Measurements of leaf area, weight, thickne
Laboratory Safety Principles
This workshop will cover major principles and regulations pertinent to working in laboratories with hazardous materials. It will be divided into 45 minute segments dealing with: Radioactive Materials (Staiger); Toxic, Reactive, Carcinogenic, and Teratogenic Chemicals (Carlson); Infectious Agents (Laver); and Fire Safety Concepts and Physical Hazards (Arnston).
