This presentation was developed by a member of MIT's electric vehicle team and provides a basic overview of electric and hybrid electric vehicle (EV and HEV) history, operation, challenges, and advantages. Discussed is EV/HEV history dating from 1830- 2010, the operation of EV/HEV systems (networking and sourcing of power throughout components), challenges (ranges, energy equivalence, consumer acceptance, charge time, grid integration, and cost), advantages (energy efficiency, fuel cost, and emissions), meeting challenges (convenient charging and improving technology), EV/HEV vehicles today (Chevrolet Volt, Tesla Roadster, and Fisker Karma), and MIT's electric vehicle team (projects, awards, and competitions).

This module describes the current and ongoing dependence on oil fueled transportation and the alternatives being considered to solve the need for sustainable energy. The following topics are discussed in the module: the rising global dependence on oil and the need for new technologies to fuel transportation,emerging technologies being highly considered to replace oil such as electric, hybrid electric, and hydrogen fuel cell vehicles, the advantages and disadvantages of each technology, and a comparison of the carbon footprint of each technology in writing and charts.Four review questions are supplied to test students on their knowledge of the material and to provide critical thinking as to their ideas for the future and solution for sustainable energy transportation.

The grand challenge for this legacy cycle unit is for students to design a way to help a recycler separate aluminum from steel scrap metal. In previous lessons, they have looked at how magnetism might be utilized. In this lesson, students think about how they might use magnets and how they might confront the problem of turning the magnetic field off. Through the accompanying activity students explore the nature of an electrically induced magnetic field and its applicability to the needed magnet.

This simple demonstration shows the interaction between electricity and magnetism. Two coils of wire are held close to each other, but not touching. One is attached to a music source, such as a small radio or iPod, and the other is attached to an external speaker. Students can hear the music through the speaker even though there is no direct connection.

Students are presented with a hypothetical scenario that delivers the unit's Grand Challenge Question: To apply an understanding of nanoparticles to treat, detect and protect against skin cancer. Towards finding a solution, they begin the research phase by investigating the first research question: What is electromagnetic energy? Students learn about the electromagnetic spectrum, ultraviolet radiation (including UVA, UVB and UVC rays), photon energy, the relationship between wave frequency and energy (c = λν), as well as about the Earth's ozone-layer protection and that nanoparticles are being used for medical applications. The lecture material also includes information on photo energy and the dual particle/wave model of light. Students complete a problem set to calculate frequency and energy.

In this activity, the students will complete the grand challenge and design an electromagnet to separate steel from aluminum for the recycler. In order to do this, students compare the induced magnetic field of an electric current with the magnetic field of a permanent magnet and must make the former look like the latter. They discover that looping the current produces the desired effect and find ways to further strengthen the magnetic field.

In this electrochemistry activity, learners will explore two examples of electroplating. In Part 1, zinc from a galvanized nail (an iron nail which has been coated with zinc by dipping it in molten zinc) will be plated onto a copper penny. In Part 2, copper from a penny will be plated onto a nickel.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water. The plastic will attract the surface of the water into a visible bump.

Use a series of interactive models and games to explore electrostatics. Learn about the effects positive and negative charges have on one another, and investigate these effects further through games. Learn about Coulomb's law and the concept that both the distance between the charges and the difference in the charges affect the strength of the force. Explore polarization at an atomic level, and learn how a material that does not hold any net charge can be attracted to a charged object. Students will be able to:

El presente artículo presenta los resultados de una investigación que analiza el nivel de calidad reflexiva de los profesores, en el marco de un programa innovador de formación docente que introduce la práctica reflexiva, mediada y gestionada a través de un portafolio digital. Aporta a la discusión sobre nuevos usos de un portafolio digital para mejorar los procesos de reflexión por parte del profesorado y sobre modelos alternativos de formación docente; analiza los diferentes niveles de reflexión de los participantes, e identifica los obstáculos para lograr niveles de mayor profundidad. La metodología de investigación adoptada ha sidoun estudio instrumental de caso, en el marco de un programa de formación del profesorado universitario. Los resultados obtenidos muestran que el proceso reflexivo contribuye a una percepción positiva sobre la mejora de su desempeño, la planificación de sus clases y una mejor interacción con los alumnos, y que el uso del portafolio digital ha sido bien valorado para el desarrollo del proceso reflexivo propuesto. Asimismo, se identifican carencias, sobre todo en relación con los niveles de profundidad de la reflexión docente. Por último, se presenta una propuesta de indicadores para impulsar y evaluar el desarrollo reflexivo, basada en los hallazgos del estudio.

In this activity, students are divided into a group of hormones and a group of receptors. The hormones have to find their matching receptors, and the pair, once matched, perform a given action. This activity helps students learn about the specificity of hormone-receptor interactions within the endocrine system.

Students learn to apply the principles and concepts associated with energy and the transfer of energy in an engineering context by designing and making musical instruments. They choose from a variety of provided supplies to make instruments capable of producing three different tones. After completing their designs, students explain the energy transfer mechanism in detail and describe how they could make their instruments better.

Students search for clues of energy around them. They use what they find to create their own definition of energy. They also relate their energy clues to the engineering products they encounter every day.
