"I Limited My Own Family": Memoir of a 1920s Birth Control Activist
Born in Forreston, Illinois, in 1868, Sylvie Thygeson taught and worked as a stenographer and typist before her marriage at the age of twenty-three. She and her husband, a lawyer, lived in St. Paul, Minnesota. An activist for women's rights, including suffrage and the legalization of contraception, Thygeson felt that birth control was both a crucial part of egalitarian marriage and a major political commitment.

Seeing the Invisible
Students will be instructed to make an observation of a flower (tulip) given the one stipulation that they will only be allowed to detect the parts of the plant that are green. Through observation and discussion, students will be led to understand that only seeing parts of the flower leads to an incomplete and even inaccurate understanding of its structure. Students will construct their own knowledge of the Sun emitting light above and below the visible spectrum by using UV beads to detect ultr

This work proposes a multicast hybrid satellite system capable of supporting advanced IRP collaboration, and evaluates its feasibility and applicability. Following a detailed IRP requirements study, we have developed a system which supports IRP collaboration through the employment of a hybrid satellite-terrestrial network, a prototype multicast version of wavelet based interactive communication

Tonto National Monument: Saving a National Treasure
tells the story of the Salado people, who thrived in the Arizona valley where Tonto Creek joins the Salt River (1050-1450 AD). The Salado culture combined customs of several American Indian groups. They channeled the river to create farmland in the desert. They built Pueblo-style buildings. They left no written records. This monument, established in December 1907, was among the first sites protected under the Antiquities Act of 1906.

What Can We Learn About Our Seasons?
The purpose of this resource is to have students develop a qualitative understanding of the characteristics and patterns of seasons and highlight the relationship of seasons to physical, biological and cultural markers. Students observe and record seasonal changes in their local study site. They establish that these phenomena follow annual cycles and conclude the activity by creating displays that illustrate the repeating pattern associated with the appearance and disappearance of seasonal marke

Conflict resolution: Working with perceptions
This unit deals with one of the "non-linear" dimensions of cooperative problem solving - perceptions. If we understand that each of us experiences the world differently, then we can use our different perceptions as sources of creativity and understanding, rather than as sources of dissent.
