Uses primary sources to explore the impacts World War I had on the struggle for civil rights in Connecticut and America.
In this activity, students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also learn several things that engineers are doing to reduce the effects of acid rain.
How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?
Students conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.
Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them.
Students play and record the “Mary Had a Little Lamb” song using musical instruments and analyze the intensity of the sound using free audio editing and recording software. Then they use hollow Styrofoam half-spheres as acoustic mirrors (devices that reflect and focus sound), determine the radius of curvature of the mirror and calculate its focal length. Students place a microphone at the acoustic mirror focal point, re-record their songs, and compare the sound intensity on plot spectrums generated from their recordings both with and without the acoustic mirrors. A worksheet and KWL chart are provided.
Provides acoustical background necessary to understand the role of sound in speech communication. Analyzes constraints imposed by the properties of sound and human anatomy on speech production (sound production from airflow and filtering by the vocal tract); auditory physiology (transformation of acoustical waves in the air to mechanical vibrations of cochlear structures); and sound perception (spatial hearing, masking, and auditory frequency selectivity). The Acoustics of Speech and Hearing is an H-Level graduate course that reviews the physical processes involved in the production, propagation and reception of human speech. Particular attention is paid to how the acoustics and mechanics of the speech and auditory system define what sounds we are capable of producing and what sounds we can sense. Areas of discussion include: 1. the acoustic cues used in determining the direction of a sound source, 2. the acoustic and mechanical mechanisms involved in speech production and 3. the acoustic and mechanical mechanism used to transduce and analyze sounds in the ear
Students construct rockets from balloons propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket.
Students make rockets that travel along a string.
Active Calculus is different from most existing calculus texts in at least the following ways: the text is free for download by students and instructors in .pdf format; in the electronic format, graphics are in full color and there are live html links to java applets; the text is open source, and interested instructors can gain access to the original source files upon request; the style of the text requires students to be active learners — there are very few worked examples in the text, with there instead being 3-4 activities per section that engage students in connecting ideas, solving problems, and developing understanding of key calculus concepts; each section begins with motivating questions, a brief introduction, and a preview activity, all of which are designed to be read and completed prior to class; the exercises are few in number and challenging in nature.
Active Calculus Multivariable is the continuation of Active Calculus to multivariable functions. The Active Calculus texts are different from most existing calculus texts in at least the following ways: the texts are free for download by students and instructors in .pdf format; in the electronic format, graphics are in full color and there are live html links to java applets; the texts are open source, and interested instructors can gain access to the original source files upon request; the style of the texts requires students to be active learners — there are very few worked examples in the texts, with there instead being 3-4 activities per section that engage students in connecting ideas, solving problems, and developing understanding of key calculus concepts; each section begins with motivating questions, a brief introduction, and a preview activity, all of which are designed to be read and completed prior to class; the exercises are few in number and challenging in nature.
In this activity, students watch a short clip from the ASHP documentary 1877: The Grand Army of Starvationto learn about the impact of railroad expansion on Americans and the nation as a whole. After watching the clip, students complete the “Technological Turning Points and their Impact” worksheet in order to examine the positive and negative effects of the railroad.
PBS American Experience’s Abraham and Mary Lincoln: A House Dividedis a 6 episode mini-series available as a 3 DVD set. The following activity focuses on the causes and consequences of Lincoln’s Emancipation Proclamation through an active viewing of Episode 4: The Dearest of All Things(Disc 2). There is a companion website to the series, The Time of the Lincolns, that contains a Teacher’s Guide, primary sources, and episode transcripts.
In this activity, students watch short clips of the PBS/A Bill Moyers Special production ofBecoming American: The Chinese Experience(2003). The documentary clips and accompanying materials cover the arrival of Chinese in California, their work on the transcontinental railroad, the passage of the 1882 Chinese Exclusion Act, and the Angel Island immigration facility. At the end of the activity, students complete a short writing task on whether not to immigrate to the United States from the perspective of a young Chinese man.
In this activity, students watch short clips of the ASHP documentary Daughters of Free Mento learn about the experiences of Lowell mill girls in the 1830s. Students follow the life of Lucy, a young girl working in Lowell in 1836. After each clip, students reflect on what they have just learned and predict what Lucy will do next.
In this activity students analyze the reasons why the Montgomery Bus Boycott lasted so long and was successful. Students watch a short clip from the PBS documentary Eyes on the Prizeabout the Montgomery Bus Boycott. Then students analyze primary sources to determine who participated in the boycott, who organized it, and what challenges boycott supporters faced. The teacher will need access to the filmEyes on the Prize, which is widely available in school and public libraries.
In this activity, students watch the documentary Heaven Will Protect the Working Girlin sections, with documents and exercises designed to support and reinforce the film's key concepts: workers challenging the effects of industrial capitalism, the impact on immigrant families of young women earning money in the garment industry, and the methods used by women to improve working conditions in factories during the Progressive Era.
This activity is designed to help students understand key ideas from the documentary film Savage Acts: Wars, Fairs, and Empire 1898-1904. The film is divided into short segments with suggested viewing strategies and questions to keep students focused.
In this activity, students watch film clips from the documentary The Life and Times of Rosie the Riveter, decode a propaganda poster, and analyze statistics about working women during World War II. Parts of this activity can be completed without the film.
In this activity, students watch the ASHP documentary Up South: African-American Migration in the Era of the Great Warwith documents and exercises designed to support and reinforce the documentary's key concepts of Jim Crow, lynching, sharecropping, migration, and life in northern cities. At the end of the activity, students complete a short writing task on how life changed and how it stayed the same for migrants, and how they tried to improve their lives in the North.
