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.

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.

How does a lens form an image? See how light rays are refracted by a lens. Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen.

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 site features a report on the historic 1891 discovery of a giant Cretaceous fossil shark (Cretoxyrhina) and the recent excavation of a similar specimen from the chalk deposits of Gove County, Kansas. Several photos, illustrations, references and relevant links accompany this thorough account of the shark's discovery and excavation.

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.

In this lesson students will use information from articles about microorganisms and their prior knowledge to identify both the positive and negative aspects of microorganisms.

Grade 3 Life Science Module. In this module, students learn about inheritance, variation, and frog ponds. The Life Science Module represents three additional hours per week of instruction during the eight to nine weeks covered by Grade 3: Module 2 of the EL Education K-8 Language Arts Curriculum. Although the Life Science Modules can stand alone, each one connects with and complements Module 2 of the grade-level language arts module lessons in Grades 3-5. To learn more about the Language Arts curriculum and how the Life Science Modules align with the language arts content, visit https://eleducation.org/resources/k-5-language-arts-guidance-document.
