Household Energy Conservation and Efficiency
Students complete three different activities to evaluate the energy consumption in a household and explore potential ways to reduce that consumption. The focus is on conservation and energy efficient electrical devices and appliances. The lesson reinforces the relationship between power and energy and associated measurements and calculations required to evaluate energy consumption. The lesson provides the students with more concrete information for completing their culminating unit assignment.
Designing Bridges
Students learn about the types of possible loads, how to calculate ultimate load combinations, and investigate the different sizes for the beams (girders) and columns (piers) of simple bridge design. Students learn the steps that engineers use to design bridges: understanding the problem, determining the potential bridge loads, calculating the highest possible load, and calculating the amount of material needed to resist the loads.
You're a Pushover!
The purpose of this activity is to demonstrate Newton's 3rd Law of Motion, which is the physical law that governs thrust in aircraft. The students will do several activities that show that for every action there is an equal and opposite reaction.
Bubbling Plants
Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determine the measures of
Snow Cover over North America during the Winter of 2001-2002 (WMS)
The amount of snow covering the land has both short and long term effects on the environment. From season to season, snow coverage and depth affect soil moisture and water availability, which directly influence agriculture, wildfire occurrences, and drought. In the long term, the part of the Earths surface covered by snow reflects up to 80 or 90 percent of the incoming solar radiation as opposed to the 10 or 20 percent that uncovered land reflects, and this has important consequences for the Ear
Traditional Chinese Paper
This 1:48 video shows how one Chinese town still makes paper the traditional way. The students will learn how the bamboo is harvested, turned into pulp, and made into paper.

"Such Cases of Outrageous Unspeakable Abuse...": A Puerto Rican Migrant Protests Labor Conditions Du
In 1917 the United States declared the inhabitants of Puerto Rico, a U.S. possession since 1898, to be citizens of the United States--a "gift" that many Puerto Ricans resented. Seeing an untapped source of inexpensive labor, the U.S. Labor Department worked with industry to facilitate the migration of Puerto Rican workers to America. During the First World War the War Department agreed to transport Puerto Rican workers to labor camps in the United States where they would be housed and fed while
South Boston High School, tape 1
African American students board buses at South Boston High School. Boston Police officers are stationed near the school. Police cruisers escort buses to and from the school. Jerome Wynegar (Headmaster, South Boston High School) stands in the schoolyard. White students exit the school after the buses depart. A passerby tells the camera crew that their presence causes a disturbance.
UMass Amherst protest ends
A group of minority students exit the New Africa House on the campus of the University of Massachusetts at Amherst. The students hold a press conference in front of the media and a group of supporters. An African American male student reads a prepared statement, announcing the end of the occupation of the New Africa House. The student says that the protesters are pleased that the New Africa House will be restored as a cultural center for African American and third world students. He adds that th
2.2 Size and shape
In the 18th and 19th century evolutionary biologists, including Darwin, emphasised the similarities between natural evolution and artificial ‘ improvement’ of livestock under domestication. They believed that studying domesticated animals and plants could illuminate the mechanisms of natural evolution.
