In this video excerpt from NOVA, find out how the discovery of a gene defect has led to the development of a new drug to treat patients with cystic fibrosis.

This video segment describes the basics of the circulatory system: how the heart pumps the blood that carries oxygen and nutrients throughout the body.

This video segment adapted from NOVA scienceNOW shows how the common wood frog freezes solid every winter, an adaptation that allows the organism to survive the cold winter.

This is a field activity where students explore different types of gardens comparing how they are the same and different.

This problem challenges students to design experiments using techniques measuring gene expression (reverse transcriptase PCR, microarrays, in situ hybridization).

In this animation produced by WGBH and Digizyme, Inc., see how bacterial plasmids are engineered to clone or express genes that code for proteins such as human insulin.

This video segment from the Secret of Life School Video: "On the Brink: Portraits of Modern Science" explores the genetics of breast cancer.

The shared set of genes for body segments, possessed by all animals, are discussed in this video segment from Evolution: "Great Transformations."

In this video profile adapted from NOVA scienceNOW, learn about geneticist and rock musician Pardis Sabeti, whose innovative insights into natural selection demonstrated how beneficial mutations spread quickly through a population.

The Geniverse software is being developed as part of a five-year research project funded by the National Science Foundation. Still in its early stages, a Beta version of the software is currently being piloted in six schools throughout New England. We invite you to try the current Beta version, keeping in mind that you may encounter errors or pages that are not fully functional. If you encounter any problem, it may help to refresh or reload the web page.

In this lab activity students isolate genomic DNA from their cheek cells on the inside of their mouths. Students then remove the DNA from those cheek cells. It shows the DNA is in every cell in the body and can be extracted easily. Students use their DNA necklace which they proudly wear around school the rest of the day.

This article provides links to web sites about geologic time, fossils, and the archaeology and culture of the Arctic for elementary teachers.

This ZOOMSci video segment teaches you how to germinate seeds in a plastic bag and helps you understand some of the factors that influence the germination process.

This video segment, adapted from NOVA, chronicles the education of leading chemist Percy Julian. Although Julian began his elementary school years in the Deep South under Jim Crow laws, he became one of the few African Americans of his time to earn a Ph.D.

This video segment from Outdoor Nevada looks at the Gila monster's behavior, habitat, and unique adaptive characteristics.

Students are given a problem about a relatively new treatment for cancer, Gleevec, and asked to apply and synthesize what they have learned about cell signaling and the eukaryotic cell cycle to explain why this targeted treatment works to prevent cell division with fewer side effects than traditional chemotherapeutic agents.

In this video segment adapted from Spanner Films, visit the Alaska Native village of Shishmaref, and learn how an entire town may be forced to relocate because of warmer temperatures, melting sea ice, and coastal erosion.

Students will answer the Challenge Question and use the acquired learning from Lesson 1, "Fix the Hip Challenge" and Lesson 2, "Skeletal System Overview"to construct an informative brochure addressing osteoporosis and the role biomedical engineering plays in diagnosing and preventing this disease.

This activity gives kindergartners the chance to get outside collect, observe and sort leaves. They will also try to differentiate between MN native leaves and non-native leaves to MN.

Students collect protein electrophoresis data comparing goldenrod gall flies, analyze class data, and write a lab report in the format of a scientific paper.
