Bird nest
Most birds make homes called nests. They are built out of twigs, hair, bits of trash, mud, and many other items. Many birds build these nests in tree branches, but they can also be built on the ground or on buildings such as rooftops.
Bee on flower
Bees visit flowering plants to collect nectar so they can store it as honey back at their hives. As a bee visits one flower after another, pollen collects on its entire body and especially on the legs. Bees help pollinate flowers while they collect nectar. This is a mutualistic behavior.
Basic Needs: U.S. currency
Humans need to feel financially safe and stable.
Arm muscles
Human arm muscles are connected to the bones by things called tendons. Tendons are rope-like fibers that join muscles to bones and allow movement.
Arabidopsis gravitropism
Gravitropism is the turning or growing in a different direction of a plant in response to gravity. This plant's shoots grow upward and exhibit negative gravitropism because they are growing away from gravity's pull.
Apple Screen 1
The apple has just fallen from the tree and rests on the ground.
A 3-Dimensional Model of the Magnetosphere (WMS)
The earths magnetosphere protects the earth from high-energy charged particles coming from the sun. Some charged particles are deflected by the magnetosphere, while others become trapped and produce the aurora. This presentation shows a 3-dimensional model of the magnetosphere. The features that it highlights are flat ribbons representing the paths of charged particles deflected by the magnetosphere, triangular ribbons representing magnetic field lines, and colored surfaces representing constant

Progression of Hurricane Jeanne, 2004 (WMS)
Hurricane Jeanne was the fourth hurricane to hit Florida during the 2004 hurricane season. This set of images shows the progression of the hurricane as it approached Florida from the Atlantic Ocean and the Caribbean Sea. When it hit the Florida coast on September 26, Jeanne was a Category 3 storm with sustained winds near 115 miles per hour.
Selected Topics in Architecture: Architecture from 1750 to the Present, Fall 2004
General study of modern architecture as a response to important technological, cultural, environmental, aesthetic, and theoretical challenges after the European Enlightenment. Focus on the theoretical, historiographic, and design approaches to architectural problems encountered in the age of industrial and post-industrial expansion across the globe, with specific attention to the dominance of European modernism in setting the agenda for the discourse of a global modernity at large. Explores mode

Statistical Reasoning II
Statistical Reasoning in Public Health II provides an introduction to selected important topics in biostatistical concepts and reasoning through lectures, exercises, and bulletin board discussions. The course builds on the material in Statistical Reasoning in Public Health I , extending the statistical procedures discussed in that course to the multivariate realm, via multiple regression methods. New topics, such as methods for clinical diagnostic testing, and univariate, bivariate, and multivar
Statistical Reasoning I
Statistical Reasoning in Public Health provides an introduction to selected important topics in biostatistical concepts and reasoning through lectures, exercises, and bulletin board discussions. It represents an introduction to the field and provides a survey of data and data types. Specific topics include tools for describing central tendency and variability in data; methods for performing inference on population means and proportions via sample data; statistical hypothesis testing and its appl
Problem Solving for Immunization Programs
Countries around the world - even those at war - are collaborating to ensure that children under the age of five don't die from diseases for which vaccines are available. In the past twenty years, global vaccine coverage has surpassed eighty percent, and a second disease, polio, is nearly eradicated. In the United States, coverage rates are even higher, and vaccine-preventable diseases are now rare. Never have so many resources been focused on immunization - yet problems remain. Additional, high
