Gulf Coast Geology
This website is part of the Environmental Protection Agency's Gulf of Mexico Program. The program includes projects encompassing everything from improving septic systems to planting seagrass to protecting habitats. All projects aim to improve the ecological and economical health of the region. The site provides information about Gulf Coast geology as well as links to information about the Ice Age.
Water Sourcebooks
The Water Sourcebooks contain 324 activities for grades K-12 divided into four sections: K-2, 3-5, 5-8, and 9-12. Each section is divided into five chapters: Introduction to Water, Drinking Water and Wastewater Treatment, Surface Water Resources, Ground Water Resources, and Wetlands and Coastal Waters. This environmental education program explains the water management cycle using a balanced approach showing how it affects all aspects of the environment. All activities contain hands-on investigat

Calisphere Themed Collection - 1950s-1970s: Social Reform: Everyday Life
The images in this topic provide a glimpse into the daily lives and changing lifestyles of Californians during the 1950s, 60s, and 70s, as the country moved from postwar to protest. From birthday parties and family meals to homecoming rallies and political protests, these photographs reflect how life looked during those years. Two images show Californians interacting with political figures who shaped those decades.
Calisphere Themed Collection - 1929-1939: The Great Depression: Everyday Life in Hard Times
The images in this topic provide a look at the everyday lives of Californians during the decade of the 1930s. Although many people struggled to survive during the Great Depression, these photographs also show that some still found employment, and many managed to enjoy themselves despite the hard economic times.
Regulation of Blood Glucose Levels in Normal and Diabetic Rats
This exercise demonstrates the crucial role insulin plays in blood glucose homeostasis in mammals. Three pairs of fasted rats are tested in each of three different regimes; one rat of each pair is normal and the other is diabetic. The first pair is administered an oral glucose load and a placebo injection of saline. The second pair is administered an oral glucose load and an insulin injection. The third pair is administered an oral placebo of water and a placebo injection of saline. The blood gl
California juniper tree
The juniper tree is a gymnosperm from the phylum of conifers. The cone is the reproductive structure of conifers. The berry-like structures are actually cones where reproduction occurs.
Animal Defenses: Zebra
Zebras generally stay in herds together. Zebras standing together may tend to look like one very large animal to predators. Also, predatory attacks send the zebras running in every direction. The stripes could confuse the attacker as to which animal it is chasing after, leaving it without any food in the end.
Learning to classify land plants
There are four main groups of land plants: bryophytes, seedless vascular plants, angiosperms (flowering), and gymnosperms (cone-producing). The four groups are distinguished by structural and reproductive traits.
Root behavior
Roots can grow in multiple directions. Just because this plant was in a cup didn't stop the roots from growing longer and creating individual branches.

Numerical Simulation of Magnetic Flux Emerging Through a Model Solar Atmosphere: Density, Magnetic F
This animation is one of a series depicting the results of a two-dimensional ideal magneto-hydrodynamic simulation of magnetic flux emerging through a solar atmosphere. The simulation has a resolution of 300x500 cells and a length scale of 16 Mm x 6.8 Mm. The simulation depicts 1730 seconds in the evolution of the model.
El Nino-La Nina Sea Surface Temp and Height Anomaly 3D Isometric View: December 1997 through April 2
Isomorphic view of El Nino. Sea surface temperature anomalies are colors, with red being warmer than normal and blue being colder than normal, and sea surface height anomalies are exaggerated heights.

Clouds over Florida from GOES-11: August 4, 2000
This animation is one of a series showing the first data from GOES-11. The data shown was taken at one-minute intervals.
Critical Analysis of Popular Diets and Dietary Supplements
There is much controversy and anecdotal information about popular diets and dietary supplements, but all too often little scientific or controlled clinical data. We examine the science behind normal mechanisms of weight control, and how weight loss diets are constructed and work. The aim of the course is to acquire the knowledge to critically appraise a weight control diet or dietary supplement and choose the best plan for success, both in the short-term and the long run. Students taking the act
Understanding Cost-Effectiveness Analysis in Health Care
The primary objective of this content is to prepare students to read and interpret cost-effectiveness studies. The students will first be introduced to basic economic concepts that are needed in order to understand the recommendations from the United States Panel on Cost Effectiveness in Health and Medicine. One example is the distinction between opportunity costs and budgetary costs. The recommendations will then be reviewed, particularly as they apply to what students should expect to read in
Family Planning Policies and Programs
Introduces issues and programmatic strategies related to the development, organization, and management of family planning programs, especially those in developing countries. Topics include social, economic, health, and human rights rationale for family planning; identifying and measuring populations in need of family planning services; social, cultural, political, and ethical barriers; contraceptive methods and their programmatic requirements; strategic alternatives, including integrated and ver
Analog Integrated Circuit Design
An introductory course in analog circuit synthesis for microelectronic designers. Topics include: Review of analog design basics; linear and non-linear analog building blocks: harmonic oscillators, (static and dynamic) translinear circuits, wideband amplifiers, filters; physical layout for robust analog circuits; design of voltage sources ranging from simple voltage dividers to high-performance bandgaps, and current source implementations from a single resistor to high-quality references based o
