This course focuses on one important engineering application of superconductors - the generation of large-scale and intense magnetic fields. It includes a review of electromagnetic theory; detailed treatment of magnet design and operational issues, including "usable" superconductors, field and stress analyses, magnet instabilities, ac losses and mechanical disturbances, quench and protection, experimental techniques, and cryogenics. The course also examines new high-temperature superconductors for magnets, as well as design and operational issues at high temperatures.

Students explore how pendulums work and why they are useful in everyday applications. In a hands-on activity, they experiment with string length, pendulum weight and angle of release. In an associated literacy activity, students explore the mechanical concept of rhythm, based on the principle of oscillation, in a broader biological and cultural context in dance and sports, poetry and other literary forms, and communication in general.

Upon successful completion of this course, students will be able to: * Create lumped parameter models (expressed as ODEs) of simple dynamic systems in the electrical and mechanical energy domains * Make quantitative estimates of model parameters from experimental measurements * Obtain the time-domain response of linear systems to initial conditions and/or common forcing functions (specifically; impulse, step and ramp input) by both analytical and computational methods * Obtain the frequency-domain response of linear systems to sinusoidal inputs * Compensate the transient response of dynamic systems using feedback techniques * Design, implement and test an active control system to achieve a desired performance measureMastery of these topics will be assessed via homework, quizzes/exams, and lab assignments.

In this activity, learners explore center of gravity, or balance point, of stacked blocks. Simple wooden blocks can be stacked so that the top block extends completely past the end of the bottom block, seemingly in a dramatic defiance of gravity. A mathematical pattern can be noted in the stacking.

Students measure different types of small-sized beams and calculate their respective moments of inertia. They compare the calculations to how much the beams bend when loads are placed on them, gaining insight into the ideal geometry and material for load-bearing beams.

Students conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. To learn the telltale marks of failure caused by these load types, they break foam insulation blocks by applying these five load types, carefully examine each type of fracture pattern (break in the material) and make drawings of the fracture patterns.

In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space. When the viewer tries to touch the lightbulb, they are attempting to touch an image. Their hand moves right through what seems to be a solid object! Learners will enjoy this illusion, while investigating principles of light and mirrors. In this version of a popular Exploratorium exhibit, a lightbulb is substituted for a spring.

The emergence of Western science: the systematization of natural knowledge in the ancient world, the transmission of the classical legacy to the Latin West, and the revolt from classical thought during the scientific revolution. Examines scientific concepts in light of their cultural and historical contexts.

Students learn about traffic lights and their importance in maintaining public safety and order. Using a Parallax® Basic Stamp 2 microcontroller, students work in teams on the engineering challenge to build a traffic light with a specific behavior. In the process, they learn about light-emitting diodes (LEDs), and how their use can save energy. Students also design their own requirements based on real-world observations as they learn about traffic safety and work towards an interesting goal within the realm of what is important in practice. Knowledge gained from the activity is directly transferrable to future activities, and skills learned are scalable to more ambitious class projects.

In this unit, students use what they’ve learned about forces and motion to design a protective cell phone case that meets criteria and constraints. Throughout the unit, students use hands-on experiences and systems modeling to explore properties of force and motion, while planning fair investigations for their cell phone case designs.
This unit has been reviewed by the NextGenScience (formerly Achieve) Science Peer Review Panel and has been identified as a quality example of NGSS design.

In this article, teachers find two unit plans (grades K-2 and 3-5) that use resources featured in the science and literacy articles in the magazine. The unit plans are modeled after the five key steps in the learning cycle: engage, explore, explain, expand, and assess, or evaluate. The plans are aligned with the science content standards of the National Science Education Standards and the English language arts standards of the National Council of Teachers of English and the International Reading Association. The plans appear in the free, online magazine Beyond Weather and the Water Cycle.

This video is meant to be a fun, hands-on session that gets students to think hard about how machines work. It teaches them the connection between the geometry that they study and the kinematics that engineers use -- explaining that kinematics is simply geometry in motion. In this lesson, geometry will be used in a way that students are not used to. Materials necessary for the hands-on activities include two options: pegboard, nails/screws and a small saw; or colored construction paper, thumbtacks and scissors. Some in-class activities for the breaks between the video segments include: exploring the role of geometry in a slider-crank mechanism; determining at which point to locate a joint or bearing in a mechanism; recognizing useful mechanisms in the students' communities that employ the same guided motion they have been studying.
