This wiki page documents the Projection Investigation Activity done during San Francisco Unified School District's SLANT workshop on January 29, 2011. Projection information, Julia Marshall's 5 Ways to Integrate, and links are provided, as well as the introductory Improv Activity "Advertising Team" which stretches the imagination to design something for the future. The Projection Investigation Activity begins with research around a scientific theme, then brainstorming and prototyping design ideas around that theme, and finally writing a narrative to present the prototype.
Students are introduced to the (hypothetical) task of developing an invisible (non-intrusive) security system to protect the school's treasured mummified troll! Solving the challenge depends on an understanding of the properties of light. After being introduced to the challenge question, students generate ideas and consider the knowledge required find solutions. They watch a portion of the "Mythbuster's Crimes and Myth-Demeanors" episode ($20), which helps direct their research and learning toward solving the challenge. They begin to study laser applications in security systems, coming to realize the role of lasers in today's society.
Students learn how simple machines, including wedges, were used in building both ancient pyramids and present-day skyscrapers. In a hands-on activity, students test a variety of wedges on different materials (wax, soap, clay, foam). Students gain an understanding of how simple machines are used in engineering applications to make our lives and work easier.
The topic of this video is energy in general, and specifically the ways we can quantify it. In order to make the concepts accessible to a broad audience, this video focuses on everyday things and events. How is it that energy plays a part in a child riding a scooter? How is the energy we consume in playing related to the energy on the food we eat? This video poses these questions to the class and challenges them to put a list of five such items into an ordering from most energy to least.

Explore the properties of quantum "particles" bound in potential wells. See how the wave functions and probability densities that describe them evolve (or don't evolve) over time.
The revered quantum physicist Richard Feynman once quipped, ̢ĺŰĺĎI think I can safely say that nobody understands quantum mechanics.̢ĺŰĺ And yet, the study of quantum mechanics has given birth to the laser, the microchip, and the electron microscope. What̢ĺŰĺŞs going on here? You can find out by taking Quantum Physics I, a completely free online class from MIT. The Syllabus is a great way to get situated with the course offerings and the Readings section offers links to help purchase the necessary books. When ready, strap yourself into your office chair and launch into the 24 one-hour-long Lecture Videos. Don̢ĺŰĺŞt forget the Lecture Notes (you̢ĺŰĺŞll need those!), as well as Assignments, Exams, and Study Materials. If you have ever longed to understand the Higgs Boson or wondered how a photon can act as either a particle or a wave, this incredible, knowledge packed course from one of the top scientific universities in the world is for you.
Together, this course and 8.06 Quantum Physics III cover quantum physics with applications drawn from modern physics. Topics covered in this course include the general formalism of quantum mechanics, harmonic oscillator, quantum mechanics in three-dimensions, angular momentum, spin, and addition of angular momentum.
8.06 is the third course in the three-sequence physics undergraduate Quantum Mechanics curriculum. By the end of this course, you will be able to interpret and analyze a wide range of quantum mechanical systems using both exact analytic techniques and various approximation methods. This course will introduce some of the important model systems studied in contemporary physics, including two-dimensional electron systems, the fine structure of Hydrogen, lasers, and particle scattering.
This course is a continuation of 8.05 Quantum Physics II. It introduces some of the important model systems studied in contemporary physics, including two-dimensional electron systems, the fine structure of hydrogen, lasers, and particle scattering.
A two-semester subject on quantum theory, stressing principles: uncertainty relation, observables, eigenstates, eigenvalues, probabilities of the results of measurement, transformation theory, equations of motion, and constants of motion. Symmetry in quantum mechanics, representations of symmetry groups. Variational and perturbation approximations. Systems of identical particles and applications. Time-dependent perturbation theory. Scattering theory: phase shifts, Born approximation. The quantum theory of radiation. Second quantization and many-body theory. Relativistic quantum mechanics of one electron. This is the second semester of a two-semester subject on quantum theory, stressing principles. Topics covered include: time-dependent perturbation theory and applications to radiation, quantization of EM radiation field, adiabatic theorem and Berry's phase, symmetries in QM, many-particle systems, scattering theory, relativistic quantum mechanics, and Dirac equation.
Watch quantum "particles" tunnel through barriers. Explore the properties of the wave functions that describe these particles.
When do photons, electrons, and atoms behave like particles and when do they behave like waves? Watch waves spread out and interfere as they pass through a double slit, then get detected on a screen as tiny dots. Use quantum detectors to explore how measurements change the waves and the patterns they produce on the screen.
This article from Beyond Weather and the Water Cycle provides ideas on how school librarians can work with elementary teachers to teach about the Sun's impact on weather and climate. The author introduces the Standards for the 21st Century Learner, developed by the American Association of School Librarians. The author focuses on Standard 1, which calls for students to inquire, think critically, and gain knowledge through developing and refining questions, investigating answers, seeking divergent perspectives in information, and assessing whether the information found answers the questions posed. The free, online magazine draws its themes from the Seven Essential Principles of Climate Literacy, with each issue focusing on one of the seven principles.

The electric field lines from a point charge evolve in time as the charge moves. Watch radiation propagate outward at the speed of light as you wiggle the charge. Stop a moving charge to see bremsstrahlung (braking) radiation. Explore the radiation patterns as the charge moves with sinusoidal, circular, or linear motion. You can move the charge any way you like, as long as you don’t exceed the speed of light.
Laboratory or field work in earth, atmospheric, and planetary sciences. To be arranged with department faculty. Consult with department Education Office. This course introduces fundamentals of radon physics, geology, radiation biology; provides hands on experience of measurement of radon in MIT environments, and discusses current radon research in the fields of geology, environment, building and construction, medicine and health physics.
Explore forces, energy and work as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet. Graphs show forces, energy and work.
