Human Genetic Variation
This curriculum supplement offers activities exploring how genes and the environment influence human diversity, what role DNA sequences play in genetic differences, and more. Students are invited to assume the role of employees at a pharmaceutical company developing new drugs. A game helps show the links between genetic variation, environmental factors, and disease prevention. A family's case study on genetic variation testing exemplifies difficult moral and social questions for society.
The Brain: Understanding Neurobiology Through the Study of Addiction
This site helps students discover the fundamentals of neurobiology and how drugs change the brain. Among the topics: functions of specific brain areas; anatomy of the neuron; neurotransmission; drug action on neurons; genetic, behavioral, and environmental influences on drug addiction; and addiction as a chronic disease.
Art and Ecology
Artists are often particularly keen observers and precise recorders of the physical conditions of the natural world. As a result, paintings can be good resources for learning about ecology. Teachers can use this lesson to examine with students the interrelationship of geography, natural resources, and climate and their effects on daily life. It also addresses the roles students can take in caring for the environment. Students will look at paintings that represent cool temperate, warm temperate,
Global Warming WebQuest
Global warming has become one of the most pressing issues facing the United States and the world. The following webquest, based on the Koshland Science Museum's exhibit Global Warming: Facts and Our Future, was designed primarily to introduce high school and middle school students to the complicated issues surrounding global warming and climate change. Through participating in a fictitious scenario, students will take an active role in determining how and why climate is changing and how humans m

Environmental Catalyst Module
In the Environmental Catalysis Module, a joint project with the Institute for Environmental Catalysis at Northwestern University, students learn what a catalyst is and become aware of the use of catalysis to promote environmental protection. Besides introducing the concept of catalysis, the module also focuses other issues such as catalytic selectivity, specificity, poisoning, condition optimization, and waste minimization. The first activity of the module introduces the concept of catalysis in
Mike Durant discusses the Battle of Mogadishu
Retired Chief Warrant Officer 4 Mike Durant, a Black Hawk helicopter pilot who was shot down and held captive in Mogadishu, Somalia in 1993 spoke at the Army War College Feb. 15 about the events leading up to the battle and how it affected him personally and professionally.
Digging Up the Dirt on Soil Microbes
This hands-on exercise introduces students, grades K-8, to the idea of soil as a habitat for many different organisms, links between the biological adaptation of an organism and the physical demands of its habitat, and identification of soil and aquatic organisms. The activity includes objectives, standards addressed, materials needed, teaching tips, procedure, questions with potential answers, summary of learned material, and additional resources. The exercise was a product of the Soil and Envi
Where Do We Grow From Here?
This package of resources and lesson plans was developed to support social studies and science teachers in integrating these topics within the regular curriculum. Government, policy and planning, economics, geography, and a myriad of environmental issues are encompassed with the Smart Growth concept, and Smart Growth provides a rich source of topics for classroom investigations. Our goal is to facilitate the involvement of teachers and students in authentic government and environmental issues. T
Berkeley Lab's Environmental Energy Technologies Division develops technology that uses, converts and stores energy more efficiently and with less environmental impact, and studies the link between energy use and the environment. An important outcome of its work is the development of technologies and processes to mitigate the environmental effects of energy use.
GLOBE 1987 Global Patterns Poster
The purpose of the ESS activities associated with the GLOBE 1987 Global Patterns Poster is to help students understand the broader global context for local GLOBE measurements. Students discover patterns in global maps of environmental data, interpret those patterns, and draw conclusions and make predictions based on them; communicate those interpretations and predictions; and develop an understanding that the components of the Earth system interact. By completing this activity, students will gai
AP Environmental Science Course Material
One of the most rewarding and challenging aspects of teaching an advanced placement environmental science course is finding enriching field and lab activities for your students. These labs have been developed by an experienced team of environmental science educators in partnership with the Environmental Literacy Council. Each lab has been the subject of an extensive peer review by a number of experienced environmental science educators. The content of this initial collection is varied, and APES
Detecting Genetically Modified Food by PCR
Genetic engineering is responsible for the so-called "second green revolution." Genes that encode herbicide resistance, insect resistance, drought tolerance, frost tolerance, and other traits have been added to many plants of commercial importance. In 2003, 167 million acres of farmland worldwide were planted in genetically modified (GM) crops equal to one fourth of total land under cultivation. The most widely planted GM crops are soybeans, corn, cotton, canola, and papaya. Two important tr
HazDat, the Agency for Toxic Substances and Disease Registry's (ATSDR) Hazardous Substance Release/Health Effects Database, is the scientific and administrative database developed to provide access to information on the release of hazardous substances from Superfund sites or from emergency events and on the effects of hazardous substances on the health of human populations. The following information is included in HazDat: site characteristics, activities and site events, contaminants found, cont
COSEE Great Lakes Workshops
These asynchronous workshops focus on environmental topics related to the Great Lakes region. Subjects covered include: The solid earth system; The bedrock and formation of the Great Lakes; Life and Rocks: Current geological processes; Human impacts [vice-versa!]; and Ocean/lake deep exploration (sink holes, underwater archeology, NOAA's exploration book) studying the bottom, characteristics of the water at depth.
Cyanobacteria Health Page
This Centers for Disease Control and Prevention (CDC) Health Studies page focuses on cyanobacteria, single-celled organisms thought to be the origin of plants. Cyanobacteria live in fresh, brackish, or marine water and are of concern to the CDC and Environmental Protection Agency (EPA) because some can form harmful blooms that deplete the oxygen and block sunlight that other organisms need to live. They can also produce powerful toxins that affect the brain and liver of animals and humans. This
Hands on the Land Teaching Materials
Hands on the Land (HOL) is a network of field classrooms stretching across America from Alaska to Florida. HOL is sponsored by Partners in Resource Education, a collaboration of five Federal agencies, a non-profit foundation, schools, and other private sector partners. Public lands comprise approximately one-third of the acreage of the U.S., and you'll soon see they are rich in historical, archaeological and environmental learning opportunities. Through the HOL network of field classrooms, Feder
Digital Filter Structures and Quantization Error Analysis
Practical implementations of digital filters introduce errors due to finite-precision data and arithmetic. Many different structures, both for FIR and IIR filters, offer different trade-offs between computational complexity, memory use, precision, and error. Approximating the errors as additive noise provides fairly accurate estimates of the resulting quantization noise levels, which can be used both to predict the performance of a chosen implementation and to determine the precision needed to m
