In this activity, students discover the relationship between an object's mass and the amount of space it takes up (its volume). Students learn about the concept of displacement and how an object can float if it displaces enough water, and the concept of density and its relationship to mass and volume.

Students will consider the difference what is shared online and what might be going unshared. What you see is not always what is real. This lesson is part of a media unit curated at our Digital Citizenship website, "Who Am I Online?".

This course presents a top-down approach to communications system design. The course will cover communication theory, algorithms and implementation architectures for essential blocks in modern physical-layer communication systems (coders and decoders, filters, multi-tone modulation, synchronization sub-systems). The course is hands-on, with a project component serving as a vehicle for study of different communication techniques, architectures and implementations. This year, the project is focused on WLAN transceivers. At the end of the course, students will have gone through the complete WLAN System-On-a-Chip design process, from communication theory, through algorithm and architecture all the way to the synthesized standard-cell RTL chip representation.

6.334 examines the application of electronics to energy conversion and control. Topics covered include: modeling, analysis, and control techniques; design of power circuits including inverters, rectifiers, and DC-DC converters; analysis and design of magnetic components and filters; and characteristics of power semiconductor devices. Numerous application examples will be presented such as motion control systems, power supplies, and radio-frequency power amplifiers. The course is worth 6 engineering design points.

You can build a wide range of practical electronic devices if you understand a few basic electronics concepts and follow some simple rules. These devices include light-activated and sound-activated toys and appliances, remote controls, timers and clocks, and motorized devices. The subject begins with an overview of the fundamental concepts, followed by a series of laboratory exercises that demonstrate the basic rules, and a final project.
