"I Was More of a Citizen": A Puerto Rican Garment Worker Describes Discrimination in the 1920s
We generally think of Puerto Rican migration to the U.S. mainland as largely a post-World War II phenomenon, since more than 800,000 Puerto Ricans came to the United States between 1940 and 1969. But immigration actually started much earlier in the century; between 1915 and 1930 more than 50,000 Puerto Rican migrants headed for the United States--especially New York City. The new immigrants faced a mixed reception, particularly from immigrants from other countries. In this interview for the radi
Galaxy-Quasar Associations: Is the Big Bang Bung?
When we see a galaxy and a quasar near each other in the sky, it might be because they are really near each other, or it might be that they are far apart and just along the same line of sight. Tests performed by Alan Stockton (Astrophysical Journal 223:747-757, "The Nature of QSO Redshifts", 1978) on a sample of such pairs have shown that some galaxy-quasar pairs have the same redshift and so are accepted as being at the same distance. Other pairs with very different redshifts however have been

Imagine It's the Year 2020: Thinking About Genetics Now
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they take a look at some of the questions that go hand-in-hand with genetic cloning technologies. The site opens by telling kids that in the future, technologies like cloning may be very common and that some of the decisions we will need to make in coming years are hard. Then, they are asked to imagine that it is the year 2020 and to take a peek at what's on the minds of one futu
Discovery Collection: Marine Animals
Marine Animals is one of the AMNH Education Department's many collections of specimens and artifacts gathered the world over by explorers and scientists. In its online Discovery Collection form, Marine Animals includes an educator's Guide with suggestions for how to use the Marine Animals Discovery Collection in the classroom.
Who Are the Plants?
This online article, from Biodiversity Counts, offers a brief overview of the plant kingdom. Specifically, it covers: why plants have their own kingdom, Plantae; what separates the kingdom's two very basic categories; the plant kingdom's 10 divisions, including the number of species in each; and why some organisms that seem like plants belong instead to the kingdom Protista or the kingdom Fungi.
Kids in the Hall of Biodiversity
This biodiversity Web site for kids, part of the museum's Kids in Our Halls program, was produced by high school interns at the Museum. In includes these sections: What Do You Think About Extinction?, an interview with kids visiting the Hall of Biodiversity; Did You Know?, a collection of fun facts that includes challenges to be solved; a five-question interactive biodiversity quiz; a Q&A interview with the head of the museum's Ichthyology Department; brief articles about the origins of chocolat
You Decide: Do violent video games cause real violence in children?
This educational guide focuses on video games as a potential cause of violence in children Students are invited to examine the arguments on both sides of the debate, developing critical thinking skills as they work through the activities. Students will learn how to support their arguments with evidence and reason. It is expected that at the end of this guide students will determine where they stand on this controversial issue.

Photographs and text tell the story of rice and rural life in Southeast Asia, with an emphasis on the highlanders, or Montagnards.
Making a Contour Map
The purpose of this activity is to learn how contour maps can be made by hand. Students plot data from GLOBE schools on a map with latitude and longitude lines and draw contours based on the values plotted. A suggested extension and how to use this activity as an assessment is included.
Viscosity of the Mantle: Constraints from Post-glacial Rebound
In this lab, students determine the viscosity of a relatively viscous fluid by measuring the rate of rebound of a partially submerged object following a rapid decrease in its mass. This experiment is carried out in the context of an analysis of post-glacial rebound as a measurement of the viscosity of the mantle. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.
Using functions in an introductory geoscience course
This template and set of exercises is designed to help faculty increase the graphical literacy of their students. The template gives general guidelines for teaching students the relationship between functions and their graphical representation. The exercises help teach exponential growth and decay. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.
Experimentación en Biotecnología I (Grado en Biotecnología)
El objetivo general de la asignatura es el estudio termodinámico, desde un punto de vista experimental, de las disoluciones no ideales de electrolitos. En particular, se pretende estudiar la influencia de las sales disueltas en el agua de mar en las reacciones químicas que tienen lugar en ella. Para ello se presentan dos entornos de trabajo: uno centrado en un equilibrio heterogéneo (reacción de precipitación) y otro en uno homogéneo (reacción de formación de un complejo). La metodologí
La econometría se ha convertido en una herramienta fundamental en el análisis económico. Hace ya casi 90 años Joseph Schumpeter afirmaba que "todo economista, le guste o no, es un económetra, ya que necesita tratar de explicar sus argumentos con cifras" y desde entonces la popularidad de los modelos econométricos se ha ido incrementando gracias al aumento de la información estadística y al desarrollo de software estadístico-econométrico.En la actualidad los modelos econométricos son u
