The marine environment is unique and requires technologies that can use sound to gather information since there is little light underwater. The sea-floor is characterized using underwater sound and acoustical systems. Current technological innovations are allowing scientists to further understand and apply information about animal locations and habitat. Remote sensing and exploration with underwater vehicles allows scientists to map and understand the sea floor, and in some cases, the water column. In this lesson, the students will be shown benthic habitat images produced by GIS. These imaged will lead to a class discussion on why habitat mapping is useful and how current technology works to make bathymetry mapping possible. The teacher will then ask inquiry-based questions to have students brainstorm about the importance of bathymetry mapping.

This video provides a virtual tour of Hadrian's Villa using a 3D digital model of the villa created under the direction of Dr. Bernard Frischer. The ruins of Hadrian's Villa, in the town of Tivoli, near Rome, is spread over an area of approximately 250 acres. Many of the structures were designed by the Emperor Hadrian who ruled from 117 until his death in 138 C.E. This virual rendering is based on current archeological research and has been created in consultation with art historians, archaeologists, and museum curators with expertise in this area. Please note, a few features are necessarily assumptions based on the best available evidence.

This problem could be used as an introductory lesson to introduce group comparisons and to engage students in a question they may find amusing and interesting. More generally, the idea of the lesson could be used as a template for a project where students develop a questionnaire, sample students at their school and report on their findings.

This task involves fraction multiplication that can be solved with pictures or number lines.

This art history video discussion examines Frans Hals' "Singing Boy with Flute", c. 1623, oil on canvas (Gemaldegalerie, Staatliche Museen zu Berlin).

This art history video discussion examines Frans Hals's "Malle Babbe", c. 1633, oil on canvas, 78.50 x 66.20 cm (Gemaldegalerie, Staatliche Museen zu Berlin).

This lesson sensitizes students to the similarities and differences between cultures by comparing Shakespearean and Bunraku/Kabuki dramas. The focus of this comparison is the complex nature of revenge explored in The Tragedy of Hamlet, Prince of Denmark and Chushingura, or the Treasury of the Loyal Retainers.

In this activity students measure their hand span. A line graph is used to record the data from the glass.

In this group task students collect data and investigate whether there is a relationship between height and hand size among the students in the class.

Students explore the concept of similar right triangles and how they apply to trigonometric ratios. Use this lesson as a refresher of what trig ratios are and how they work. In addition to trigonometry, students explore a clinometer app on an Android® or iOS® device and how it can be used to test the mathematics underpinning trigonometry. This prepares student for the associated activity, during which groups each put a clinometer through its paces to better understand trigonometry.

This course introduces students to both passive and active electronic components (op-amps, 555 timers, TTL digital circuits). Basic analog and digital circuits and theory of operation are covered. The labs allow the students to master the use of electronic instruments and construct and/or solder several circuits. The labs also reinforce the concepts discussed in class with a hands-on approach and allow the students to gain significant experience with electrical instruments such as function generators, digital multimeters, oscilloscopes, logic analyzers and power supplies. In the last lab, the students build an electronic circuit that they can keep. The course is geared to freshmen and others who want an introduction to electronics circuits. This course is offered during the Independent Activities Period (IAP), which is a special 4-week term at MIT that runs from the first week of January until the end of the month.

Students learn about weight by building a spring scale and observing how it responds to objects with different masses.

This art history video discusses Hans Holbein the Younger's "Portrait of Henry VIII", 1540, oil on panel (Palazzo Barberini, Rome).

Students experience haptic (the sense of touch) feedback by using LEGO® MINDSTORMS® NXT robots and touch sensors to emulate touch feedback recognition. With four touch sensors connected to LEGO NXTs, they design sensor attachments that feel physically distinguishable from each another. Then students answer questions and communicate their answers to the NXT by pressing the touch sensor that is associated with the right multiple-choice answer letter. Haptics becomes essential when students must use the NXT sensors to answer the next set of questions without the aid of their vision. This challenges them to rely solely on the tactile feeling of each unique touch sensor attachment that they created in order to choose the correct peripheral slot. Students also learn about real-world applications of haptics technology.

Students engage in the second design challenge of the unit, which is an extension of the maze challenge they solved in the first lesson/activity of this unit. Students extend the ideas learned in the maze challenge with a focus more on the robot design. Gears are a very important part of any machine, particularly when it has a power source such as engine or motor. Specifically, students learn how to design the gear train from the LEGO MINDSTORMS(TM) NXT servomotor to the wheel to make the LEGO taskbot go faster or slower. A PowerPoint® presentation, pre/post quizzes and a worksheet are provided.

A continuation of Harmony and Counterpoint I, including chromatic harmony and modulation, a more extensive composition project, keyboard laboratory, and sight-singing laboratory.
