Anemone at the California rocky intertidal zone
Anemones are carnivores and use their tentacles to move food into their mouths. Their tentacles contain stinging cells to kill prey. Sea anemones attach to rocks in lower and middle intertidal zones and are vulnerable to drying out.
Bivariate Uniform Experiment
This resource consists of a Java applet and expository text. The Java applet illustrates the bivariate uniform distribution on three types of regions: a square, a circle, and a triangle. Simulated points from the distribution are shown as dots in a scatterplot.
Saving the DNA and the viable cells of the world's endangered animals
The mission of the Frozen Ark Project is to collect, preserve and store tissue, gametes, viable cells and DNA from endangered animals. The project focuses on the thousands of animals that are threatened with extinction. Animal species are dying out at an unprecedented rate. The current round of extinctions is largely created by mankind, because of the increase in human populations and its effect on the planet's ecosystems. Global warming is a major contributor to this destruction. Despite t
DNA Profiling by Mutliplex PCR Amplification and Genotype Determination by Reverse Dot-Blot Hybridiz
Human DNA profiling has applications in paternity testing and forensics. This exercise provides students the opportunity to gain first-hand experience with procedures that are currently used to extract DNA from their own cells, quantify the DNA in the extract, perform a multiplex PCR amplification of several loci used in forensic analysis, and determine their own genotype at those loci. In addition, methods for analyzing results relative to existing population databases will be presented. The ex
What is the genome made of?
Genomes are composed of DNA, and a knowledge of the structure of DNA is essential to understand how it can function as hereditary material. DNA is remarkable, breathtakingly simple in its structure yet capable of directing all the living processes in a cell, the production of new cells and the development of a fertilized egg to an individual adult. DNA has three key properties: it is relatively stable; its structure suggests an obvious way in which the molecule can be duplicated, or replicated;
The Thin Blue Line-Forensic Scientists
This site draws on, and brings together, many scientific disciplines-identification of hairs and fibers, forensic psychology,DNA testing, photography, bloodstain pattern analysis, and computer forensics-that contribute to the integrated analysis of a crime and the physical evidence left at a crime scene.
Red Light, Green Light
Building upon their understanding of forces and Newton's laws of motion, students learn about the force of friction, specifically with respect to cars. They explore the friction between tires and the road to learn how it affects the movement of cars while driving. In an associated literacy activity, students explore the theme of conflict in literature, and the difference between internal and external conflict, and various types of conflicts. Stories are used to discuss methods of managing and re
Move Your Muscles!
This lesson covers the topic of muscles. Students learn about the three different types of muscles in the human body and the effects of microgravity on muscles. Students also learn how astronauts need to exercise in order to lessen muscle atrophy in space. Students discover what types of equipment engineers design to help the astronauts exercise while in space.

Students form expert engineering teams working for the (fictional) alternative energy consulting firm, Greenewables, Inc. Each team specializes in a form of renewable energy used to generate electrical power: passive solar, solar photovoltaic, wind power, low-impact hydropower, biomass, geothermal and (for more advanced students) hydrogen fuel cells. Teams produce poster presentations making a case for their technology and produce an accompanying PDF document using Adobe Acrobat that summarizes
The Reproductive Revolution - Have We Gone Too Far?
We are in the middle of a reproductive revolution that is changing the way we think about fertility and social aspects of families. We have also developed new technologies in stem cells that will affect regenerative medicine. Are our technologies in reproduction too far ahead of the social consequences and ethical decisions found in our society?
Widgets, gadgets and other health technologies: Using evidence, priorities and values to guide choic
All health care systems in the world “set priorities and make choices”, but how do we inform policy makers about which health care interventions should be supported or promoted? Increasing use is being made of health technology assessment, which evaluates the safety, effectiveness, and social and ethical implications of different types of health care to guide decisions about health care policy and practice in Australia and elsewhere.
Metal-containing molecules and DNA
PhD student, Adair Richards, and Professor Alison Rodger from the Molecular Organisation and Assembly in Cells Doctoral Training Centre (MOAC) talk about their work and recent article about binding metal-containing molecules to DNA. Length: 20 minutes
Internet Scout Project
From the USDA Forest Service's St. Paul Field Office, this website offers a collection of instructive, online publications (first mentioned in the January 21, 2005 NSDL Scout Report for Life Sciences) that "are written for homeowners, land managers and others who want to know more about how to care for trees." The publications provide information about dealing with a number of diseases and other threats to a variety of tree types including Jack Pine, Oak, White Pine, Aspen, Basswood, Sugar Maple
