In this lesson, students learn about echolocation: what it is and how engineers use it to "see" things in the dark, or deep underwater. Also, they learn how animals use echolocation to catch their dinner and travel the ocean waters and skies without running into things.

Poets achieve popular acclaim only when they express clear and widely shared emotions with a forceful, distinctive, and memorable voice. But what is meant by voice in poetry, and what qualities have made the voice of Langston Hughes a favorite for so many people?

To develop an understanding of modern industrial technologies that clean up and prevent air pollution, students build and observe a variety of simple models of engineering pollutant recovery methods: scrubber, electrostatic precipitator, cyclone and baghouse. In an associated literacy activity, students become more aware of global environmental problems and play a part in their solution by writing environmental action campaign letters.

This lesson is the second of two that explore cellular respiration and population growth in yeasts. In the first lesson, students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Based on questions that arose during the first lesson and its associated activity, in this lesson students work in small groups to design experiments that will determine how environmental factors affect yeast population growth.

Students observe four different classroom setups with objects in motion (using toy cars, a ball on an incline, and a dynamics cart). At the first observation of each scenario, students sketch predicted position vs. time and velocity vs. time graphs. Then the classroom scenarios are conducted again with a motion detector and accompanying tools to produce position vs. time and velocity vs. time graphs for each scenario. Students compare their predictions with the graphs generated by technology and discuss their findings. This lesson requires assorted classroom supplies, as well as motion detector technology.

Students continue to explore the story of building a pyramid, learning about the simple machine called a pulley. They learn how a pulley can be used to change the direction of applied forces and move/lift extremely heavy objects, and the powerful mechanical advantages of using a multiple-pulley system. Students perform a simple demonstration to see the mechanical advantage of using a pulley, and they identify modern day engineering applications of pulleys. In a hands-on activity, they see how a pulley can change the direction of a force, the difference between fixed and movable pulleys, and the mechanical advantage gained with multiple / combined pulleys. They also learn the many ways engineers use pulleys for everyday purposes.

This lesson provides students with an overview of the electric power industry in the United States. Students also become familiar with the environmental impacts associated with a variety of energy sources.

The Preamble is the introduction to the United States Constitution, and it serves two central purposes. First, it states the source from which the Constitution derives its authority: the sovereign people of the United States. Second, it sets forth the ends that the Constitution and the government that it establishes are meant to serve.

Students will learn how the Preamble to the U.S. Constitution was shaped by historical events and how it reflected the fundamental values and principles of a newly independent nation.

This course will cover families of trigonometric functions, their inverses, properties, graphs, and applications. Additionally we will study trigonometric equations and identities, the laws of sines and cosines, polar coordinates and graphs, parametric equations and elementary vector operations.Login: guest_oclPassword: ocl

This course will cover families of functions, their properties, graphs and applications. These functions include: polynomial, rational, exponential, logarithmic functions and combinations of these. We will solve related equations and inequalities and conduct data analysis, introductory mathematical modeling and develop competency with a graphing calculator.Login: guest_oclPassword: ocl

A course designed to improve the student's writing ability for entrance into ENGL 101. Coursework focuses on critical reading and analytic writing in response to readings, with emphasis on organization, unity, coherence, and adequate development; an introduction to the expository essays; and a review of the rules and conventions of standard written English.Login: guest_oclPassword: ocl

This lesson culminates the unit with the Go Public phase of the legacy cycle. In the associated activity, students depict a tumor amidst healthy body tissue using a Microsoft Excel® graph. In addition, students design a brochure for both patients and doctors advertising a new form of painless yet reliable breast cancer detection. Together, the in-class activity and the take-home assignment function as an assessment of what students have learned throughout the unit.

Through these lessons, students learn to identify and describe the various roles and responsibilities of the President of the United States and their own roles as citizens of a democracy.

In order to become informed participants in a democracy, students must learn about the women and men who make decisions concerning their lives, their country, and the world. The President of the United States is one such leader. As a nation, we place no greater responsibility on any one individual than we do on the president. Through these lessons, students learn about the roles and responsibilities of the president and their own roles as citizens of a democracy.

Use this lesson to help students distinguish between primary and secondary sources and use them in them in the appropriate context.

This course is an introduction to the fundamentals of financial accounting and the first of a two-part sequence. In this course students explore the framework for all accounting processes. Students will learn to record economic events and follow a business process through the steps of the accounting cycle. Service and merchandising businesses will be covered and communication of the conclusions to decision-makers will be emphasized. This is a required class for business majors planning to transfer to a 4-year business programs in the state of Washington.Login: guest_ocl Password: ocl

This course provides an introduction to the chemistry of biological, inorganic, and organic molecules.ĺĘTheĺĘemphasis isĺĘon basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. In an effort to illuminate connections between chemistry and biology, a list of the biology-, medicine-, and MIT research-related examples used in 5.111 is provided in Biology-Related Examples. Acknowledgements Development and implementation of the biology-related materials in this course were funded through an HHMI Professors grant to Prof. Catherine L. Drennan.

Students are introduced to a systematic procedure for solving problems through a demonstration and then the application of the method to an everyday activity. The unit project is introduced to provide relevance to subsequent lessons.
