Angular Velocity: Sweet Wheels
Conditions of Use:
Read the Fine Print
Rating

Students analyze the relationship between wheel radius, linear velocity and angular velocity by using LEGO(TM) MINDSTORMS(TM) NXT robots. Given various robots with different wheel sizes and fixed motor speeds, they predict which has the fastest linear velocity. Then student teams collect and graph data to analyze the relationships between wheel size and linear velocity and find the angular velocity of the robot given its motor speed. Students explore other ways to increase linear velocity by changing motor speeds, and discuss and evaluate the optimal wheel size and desired linear velocities on vehicles.

Atomic Spectra and the Bohr Model
Conditions of Use:

Rating

Students view continuous spectra from incandescent and fluorescent lights and line spectra of selected elements. Students relate energy to frequency of light seen in the spectra. The presence of only certain lines in atomic spectra is related to Bohr's model of the atom. In a second experiment, students determine electron energies in the hydrogen atom.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Bouncing Ball Experiment
Conditions of Use:
Remix and Share
Rating

In this experiment students should be in groups of 3. Students will drop a ball from different heights and measure the corresponding bounce. Since each group will use a different ball, they will generate different sets of data. They will be asked to discuss and compare their linear function with that of their classmates. They should practice measuring the ball bounce before they begin to collect data.

Developing Musical Structures, Fall 2002
Conditions of Use:
Remix and Share
Rating

What are the roles of analysis, description and performance in developing musical perception and understanding? How are units of perception different from units of description? Bamberger's text "Developing Musical Intuitions" and the accompanying software "Impromptu" are used as environments for composing melodies and percussion pieces. These, in turn, serve as the basis for students to interrogate their musical intuitions so as to expand and develop them. Term projects involve learning to perform a new composition or an experiment in musical perception, or designing multiple representations for appropriate analysis of a significant work. The goal of this class is practical: to interrogate, make explicit, and thus to develop the powerful musical intuitions that are at work as you make sense of the music all around you. Reflecting, we will ask how this knowledge develops in ordinary and extraordinary ways.

English Romantic Poetry
Conditions of Use:

Rating

In this course, the student will examine the revolutionary energy, fascination with nature, desire to create art for the masses, and inward-facing focus of the Romantic period. First, the student will look at the broader socio-historical and literary context in which English Romantic poetry thrived, then examine the Romantic poet and the outer world, the Romantic poet and the inner world, and the poetry that bridges the gap between the two, attempting to understand what makes each poem 'Romantic.' Upon completion of this course, students will be able to: provide an account of Romanticism as both an historical period as well as a movement in art and literature; identify and explain Romanticism in terms of its relation to the French Revolution; describe the new views of society and social relations that arose during this era; explain the significance of industrialization, the rise of the working class, the expansion of British Empire, the heightening of British nationalism, and the rise of the press; explain Romanticism's relationship to Neo-Classicism; list and describe the major tenets of Romanticism, including the movement's interests in the natural world, supernaturalism, revolution, morality, ethics, exoticism, urbanization, mindscapes, moods, imagination, and interiority; provide an account of the nature and function of the Romantic craft of authorship.

Gears: Determining Angular Velocity
Conditions of Use:
Read the Fine Print
Rating

Students work as engineers and learn to conduct controlled experiments by changing one experimental variable at a time to study its effect on the experiment outcome. Specifically, they conduct experiments to determine the angular velocity for a gear train with varying gear ratios and lengths. Student groups assemble LEGO MINDSTORMS(TM) NXT robots with variously sized gears in a gear train and then design programs using the NXT software to cause the motor to rotate all the gears in the gear train. They use the LEGO data logging program and light sensors to set up experiments. They run the program with the motor and the light sensor at the same time and analyze the resulting plot in order to determine the angular velocity using the provided physics-based equations. Finally, students manipulate the gear train with different gears and different lengths in order to analyze all these factors and figure out which manipulation has a higher angular velocity. They use the equations for circumference of a circle and angular velocity; and convert units between radians and degrees.

Student teams design and conduct quality-control experiments to test the reliability of several ultraviolet protection factors. Students use UV-detecting beads in their experimental designs to test the effectiveness of various types of sunscreens and sunblock. For example, they might examine zinc oxide nanoparticles versus traditional organic sun protection factors. UV intensity is quantitatively measured by UVA and UVB Vernier sensors, and students record and graph their results. By designing and conducting this experiment, students compare various substances, while learning about quality control.

Students continue the research begun in the associated lesson as if they were biomedical engineers working for a pharmaceutical company. Groups each perform a simple chemical reaction (to precipitate solid calcium out of solution) to observe what may occur when Osteopontin levels drop in the body. With this additional research, students determine potential health complications that might arise from a new drug that could reduce inflammatory pain in many patients, improving their quality of life. The goal of this activity is to illustrate biomedical engineering as medical problem solving, as well as emphasize the importance of maintaining normal body chemistry.

Introduction to Sociology 2e adheres to the scope and sequence of a typical, one-semester introductory sociology course. It offers comprehensive coverage of core concepts, foundational scholars, and emerging theories, which are supported by a wealth of engaging learning materials. The textbook presents detailed section reviews with rich questions, discussions that help students apply their knowledge, and features that draw learners into the discipline in meaningful ways. The second edition retains the book’s conceptual organization, aligning to most courses, and has been significantly updated to reflect the latest research and provide examples most relevant to today’s students. In order to help instructors transition to the revised version, the 2e changes are described within the preface.
