The Allergy Chronicles
Read the Fine Print
Rating

The purpose of this lesson, from Science NetLinks, is to use the Internet to explore how the immune system functions in a variety of allergic reactions. In middle school, students should have had experiences studying the healthy functioning of the human body. In high school, students should relate their knowledge of normal body functioning to situations in which functioning is impaired due to environmental or hereditary causes. Also at this level, students should try to find explanations for diseases in physiological, molecular, or system terms. Since the primary purpose of this lesson is to explore the role of immune responses in allergic reactions, students should already have a working knowledge of body systems, and the immune system in particular.

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 genetics and DNA research with six AMNH scientists' journals. The Humpback Whale Journal takes kids to Madagascar to meet this endangered species. The Spotted Owl Journal takes kids to California for a look at these birds who are at risk because their forest homes are being cut down. The Sumatran Tiger Journal takes kids to Indonesia for a look at this genetically unique tiger. The Ruffed Lemur Journal also takes kids to Madagascar, but this time they venture inland to meet the endangered primate. The Pacu Journal takes kids to Brazil to meet this vegetarian relative of the meat-eating piranha. The St. Vincent Parrot Journal takes kids to the West Indies to meet the rare, colorful birds that are further at risk because of smuggling.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Detecting Genetically Modified Food by PCR
Read the Fine Print
Educational Use
Rating

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 transgenes have been widely introduced into crop plants.  The Bt gene, from Bacillus thuringiensis, produces a toxin that protects against caterpillars, reducing applications of insecticides and increasing yields. The glyphosate resistance gene protects food plants against the broad-spectrum herbicide Roundup, which efficiently kills invasive weeds in the field. The major advantages of the "Roundup Ready®" system include better weed control, reduction of crop injury, higher yield, and lower environmental impact than traditional herbicide systems. Most Americans would probably be surprised to learn that more than 60% of fresh vegetables and processed foods sold in supermarkets today are genetically modified by gene transfer.  In 2004, approximately 85% of soy and 45% of corn grown in the U.S. were grown from Roundup Ready® seed.

Discovering Genes Associated with Diseases and Traits in Dogs
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating

In this video module, students learn how scientists use genetic information from dogs to find out which gene (out of all 20,000 dog genes) is associated with any specific trait or disease of interest. This method involves comparing hundreds of dogs with the trait to hundreds of dogs not displaying the trait, and examining which position on the dog DNA is correlated with the trait (i.e. has one DNA sequence in dogs with the trait but another DNA sequence in dogs not displaying the trait). Students will also learn something about the history of dog breeds and how this history helps us find genes.

Exclusion Mapping

A useful technique for narrowing down the location of a gene involves comparing the chromosomes of affected siblings. Two sisters with Rett syndrome allow researchers an opportunity to map the most likely location of the gene by excluding areas of the chromosome that are not alike. Includes audio narration.

This lesson for students in grades 9-12 introduces DNA, genes, chromosomes, the chemicals that make up DNA. After the basic information, students will do an experiment in which they will separate out DNA from peas. Knowing that DNA can be separated will give them a base of understanding for future lessons in biology, evolution, biotechnology, and health technology.
