Malcolm X was a civil rights leader, a spokesperson for the Nation of Islam, and a leading black nationalist during the early 1960's. Viewing integration as an illusory solution to the problems of black Americans, Malcolm X advocated self-reliance, black pride, and unity. Malcolm's message became popular among Northern blacks as the Civil Rights movement failed to alleviate problems such as poverty, joblessness, police brutality, and de facto segregation. Although many Northern whites felt uncomfortable confronting racial inequities close to home, conditions for African Americans living in Northern and Western cities rivaled those of the South. In 1962 the Los Angeles Police Department, notorious in the Watts section of L.A. for harassing and brutalizing black youth, targeted the Nation of Islam in an act of violence. Malcolm X spoke out about the incident on WBAI radio.

Although the 15th Amendment, ratified in 1870, guaranteed citizens the right to vote regardless of race, by 1957 only 20 percent of eligible African Americans voted, due in part to intimidation and discriminatory state requirements such as poll taxes and literacy tests. Despite the passage of the landmark Civil Rights Act of 1964, which outlawed discrimination in employment and public accommodations based on race, religion, national origin, or sex, efforts to register African Americans as voters in the South were stymied. In 1965, following the murder of a voting rights activist by an Alabama sheriff's deputy and the subsequent attack by state troopers on a massive protest march in Selma, Alabama, President Lyndon B. Johnson pressed Congress in the following speech to pass a voting rights bill with teeth. As Majority Leader of the Senate, Johnson had helped weaken the 1957 Civil Rights Act. When he assumed the presidency following the assassination of John F. Kennedy in November 1963, however, Johnson called on Americans "to eliminate from this nation every trace of discrimination and oppression that is based upon race or color," and in the following speech adopted the "We Shall Overcome" slogan of civil rights activists. His rhetoric and subsequent efforts broke with past presidential precedents of opposition to or lukewarm support for strong civil rights legislation. Johnson signed the Voting Rights Act of 1965 into law on August 6.

Known best by his knack for moneymaking, turn-of-the-century steel magnate Andrew Carnegie nonetheless found a moment to pen a one-sided poetic tribute to the "eighth wonder" of the world--steel manufacturing in his Pittsburgh, Pennsylvania, plant. This brief poem reflected how he (and other contemporaries) viewed the monumental process of steelmaking. The poem was notable for its use of passive voice and the absence of workers--miners, railroad men, or blast furnace crews--from the process by which "one pound of solid steel" came to be.

The Andrew Jackson Papers collection documents Jackson's life in its several phases, including Jackson's military career in the War of 1812, the Creek War, and Florida; his transactions as a land-holder and Tennessee businessman; his personal and family life, including correspondence with his wife, Rachel Jackson, and other family members and wards associated with the Hermitage; and his controversies with associates and strangers, which sometimes came to confrontation. Prominent is documentation related to his complex two-term presidency, during which the nation debated issues of nullification, tariff rates, banking procedures, Indian policy, public improvements, and the relative power and sovereignty of the individual states in the Union in relation to the federal government. The collection also contains information on military orders and court martial proceedings, diplomatic and Indian treaty negotiations, and the experiences and/or opinions of those Jackson led in battle, collaborated with or opposed in politics, or trusted as cabinet members, allies and friends.

General George Washington and the patriot leaders faced an enormous challenge in mounting a military campaign against the British forces during the revolutionary war. For soldiers, they drew upon existing state militias and also raised a Continental army. But no such source for a naval force existed. Instead, Washington's officers acquired the services of American captains and sailors by commissioning them as privateers, or private citizens authorized to attack a military enemy. Colonists had long experience serving as privateers for the British forces during numerous eighteenth-century wars against Spain, France, and the Netherlands. They now turned their skills against Great Britain. Andrew Sherburne's memoirs capture the youth's enthusiastic desire to participate in the military campaign against the British; many others were less enthusiastic about their military service due to its infrequent pay and poor living conditions.

Students prepare for the associated activity in which they investigate acceleration by collecting acceleration vs. time data using the accelerometer of a sliding Android device. Based on the experimental set-up for the activity, students form hypotheses about the acceleration of the device. Students will investigate how the force on the device changes according to Newton's Second Law. Different types of acceleration, including average, instantaneous and constant acceleration, are introduced. Acceleration and force is described mathematically and in terms of processes and applications.

In the first of two sequential lessons, students create mobile apps that collect data from an Android device's accelerometer and then store that data to a database. This lesson provides practice with MIT's App Inventor software and culminates with students writing their own apps for measuring acceleration. In the second lesson, students are given an app for an Android device, which measures acceleration. They investigate acceleration by collecting acceleration vs. time data using the accelerometer of a sliding Android device. Then they use the data to create velocity vs. time graphs and approximate the maximum velocity of the device.

Students develop an app for an Android device that utilizes its built-in internal sensors, specifically the accelerometer. The goal of this activity is to teach programming design and skills using MIT's App Inventor software (free to download from the Internet) as the vehicle for learning. The activity should be exciting for students who are interested in applying what they learn to writing other applications for Android devices. Students learn the steps of the engineering design process as they identify the problem, develop solutions, select and implement a possible solution, test the solution and redesign, as needed, to accomplish the design requirements.

Students investigate the motion of a simple pendulum through direct observation and data collection using Android® devices. First, student groups create pendulums that hang from the classroom ceiling, using Android smartphones or tablets as the bobs, taking advantage of their built-in accelerometers. With the Android devices loaded with the (provided) AccelDataCapture app, groups explore the periodic motion of the pendulums, changing variables (amplitude, mass, length) to see what happens, by visual observation and via the app-generated graphs. Then teams conduct formal experiments to alter one variable while keeping all other parameters constant, performing numerous trials, identifying independent/dependent variables, collecting data and using the simple pendulum equation. Through these experiments, students investigate how pendulums move and the changing forces they experience, better understanding the relationship between a pendulum's motion and its amplitude, length and mass. They analyze the data, either on paper or by importing into a spreadsheet application. As an extension, students may also develop their own algorithms in a provided App Inventor framework in order to automatically note the time of each period.

This task provides a construction of the angle bisector of an angle by reducing it to the bisection of an angle to finding the midpoint of a line segment. It is worth observing the symmetry -- for both finding midpoints and bisecting angles, the goal is to cut an object into two equal parts. The conclusion of this task is that they are, in a sense, of exactly equivalent difficulty -- bisecting a segment allows us to bisect and angle (part a) and, conversely, bisecting an angle allows us to bisect a segment (part b). In addition to seeing how these two constructions are related, the task also provides an opportunity for students to use two different triangle congruence criteria: SSS and SAS.

In this activity, learners use a hand-made protractor to measure angles they find in playground equipment. Learners will observe that angle measurements do not change with distance, because they are distance invariant, or constant. Note: The "Pocket Protractor" activity should be done ahead as a separate activity (see related resource), but a standard protractor can be used as a substitute.

Find out how angles and symmetry come into play in the game of pool in this video adapted from Annenberg Learner’s Learning Math: Measurement.

Angles is an annual online magazine of exemplary writing by MIT students. All of the works published in Angles since its first edition in 2008 were written by students in the introductory writing courses. These courses, designated as CI-HW (Communications-Intensive Humanities Writing) subjects, bring together students who love to write, students who struggle with writing, students who thrive in seminar-style classes, and students who just want a chance to develop their English skills. These students prosper together and produce some remarkable work. Angles has provided them with a public outlet for that work. It also provides the CI-HW instructors with material that inspires and guides their current students.

In these classes, students learn to read more critically, to address specific audiences for particular purposes, to construct effective arguments and narratives, and to use and cite source material properly. Students in these courses write a great deal; they prewrite, write, revise, and edit their work for content, clarity, tone, and grammar and receive detailed feedback from instructors and classmates. Assigned readings are related to the thematic focus of each course, and are used as demonstrations of writing techniques. The pieces in Angles may be used as teaching tools and practical examples for other students and self-learners to emulate.

After using the historical development of concepts of conserved motion to develop introductory understanding, students are directed to a series of activities to gain a better understanding of momentum, conservation of momenta, angular momentum, and conservation of angular momenta.

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.

Students will create animals that have adaptations that would enable them to survive in environments that evolve after they have learned about Classification and the Animal Kingdom.

The animal alphabet is a series of slides that introduces students to Wisconsin wildlife species and other basic ecology vocabulary. Each slide has a letter of the alphabet and associated animal or ecology term. Educators can use this as a daily activity, introducing one slide each day, or present all in one sitting. The activity utilizes photographs from Snapshot Wisconsin trail cameras (except where noted) and can be used to assist in introducing the Snapshot Wisconsin program.

Most of the major categories of adaptive behavior can be seen in all animals. This course begins with the evolution of behavior, the driver of nervous system evolution, reviewed using concepts developed in ethology, sociobiology, other comparative studies, and in studies of brain evolution. The roles of various types of plasticity are considered, as well as foraging and feeding, defensive and aggressive behavior, courtship and reproduction, migration and navigation, social activities and communication, with contributions of inherited patterns and cognitive abilities. Both field and laboratory based studies are reviewed; and finally, human behavior is considered within the context of primate studies.

Students will participate in an activity that will teach them about animal adaptations.

This resource is a full tutorial on the organelles of an animal cell. The online animation includes interaction with the organelles. As you click on the organelles their function and definition pop up along with relevant animations. After completing the organelle tutorial the site offers an animal cell organelle game to check a student's understanding along with a quiz. 

This resource could be used as a precursor to direct instruction allowing student's to explore the organelles and their function prior to a formal teacher led lesson. This could also supplement students who may have been absent during the organelle lesson or are in need of further individualized instruction on the organelles. This tutorial could also be used as a culminating review for students to check their understanding of the organelles, their function, location and definition.
