The Lawrence Textile Strike was a public protest mainly of immigrant workers from several countries, including Austria, Belgium, Cuba, Canada, France, England, Germany, Greece, Ireland, Italy, Lithuania, Netherlands, Norway, Poland, Portugal, Russia, Scotland, Spain, Syria, and Turkey. According to the 1910 census, 65% of mill workers (many of whom eventually struck) lived in the United States for less than 10 years; 47% for less than five years. Prompted by a wage cut, the walkout spread quickly from mill to mill across the city. Strikers defied the assumptions of conservative trade unions within the American Federation of Labor that immigrant, largely female and ethnically diverse workers could not be organized. The Lawrence strike is referred to as the åÒBread and RosesåÓ strike and åÒThe Strike for Three Loaves." The first known source to do so was a 1916 labor anthology, The Cry for Justice: An Anthology of the Literature of Social Protest by Upton Sinclair. Prior to that, the slogan, used as the title of a 1911 poem by James Oppenheim, had been attributed to åÔChicago Women Trade Unionists.åÕ It has also been attributed to socialist union organizer Rose Schneiderman. James Oppenheim claimed his seeing women strikers in Lawrence carrying a banner proclaiming åÒWe Want Bread and Roses TooåÓ inspired the poem, åÒBread and Roses.åÓ The poem, however, was written and published in 1911 prior to the strike. Later the poem was set to music by Caroline Kohlsaat and then by Mimi Farina. The song and slogan are now important parts of the labor movement and womenåÕs movement worldwide. This exhibition was made in collaboration with the Lawrence History Center and the University of Massachusetts Lowell History Department.

Bridges come in a wide variety of sizes, shapes, and lengths and are found all over the world. It is important that bridges are strong so they are safe to cross. Design and build a your own model bridge. Test your bridge for strength using a force sensor that measures how hard you pull on your bridge. By observing a graph of the force, determine the amount of force needed to make your bridge collapse.

Construct and measure the energy efficiency and solar heat gain of a cardboard model house. Use a light bulb heater to imitate a real furnace and a temperature sensor to monitor and regulate the internal temperature of the house. Use a bright bulb in a gooseneck lamp to model sunlight at different times of the year, and test the effectiveness of windows for passive solar heating.

A bungee jump involves jumping from a tall structure while connected to a large elastic cord. Design a bungee jump that is "safe" for a hard-boiled egg. Create a safety egg harness and connect it to a rubber band, which is your the "bungee cord." Finally, attach your bungee cord to a force sensor to measures the forces that push or pull your egg.

A zip line is a way to glide from one point to another while hanging from a cable. Design and create a zip line that is safe for a hard-boiled egg. After designing a safety egg harness, connect the harness to fishing line or wire connected between two chairs of different heights using a paper clip. Learn to improve your zip line based on data. Attach a motion sensor at the bottom of your zip line and display a graph to show how smooth a ride your egg had!

Earthquakes happen when forces in the Earth cause violent shaking of the ground. Earthquakes can be very destructive to buildings and other man-made structures. Design and build various types of buildings, then test your buildings for earthquake resistance using a shake table and a force sensor that measures how hard a force pushes or pulls your building.
