This video segment from Outdoor Nevada examines threats to the desert tortoise population.
Students will be assessed for the unit on plants by designing a angiosperm, and creating a field guide for it.
This lesson plan is a cumulative activity for SEED 4.1.1Construct an explanation from evidence that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.Students create and write about a unique creature with a focus on structures leading to its survival.

This video from Nature offers a description of desirable traits in beef and dairy cattle.
In this video segment from Nature, scientists question how animals mysteriously survive natural disasters.
This video segment from Greater Boston examines whether environmental toxins may be to blame for a rare skin disease.
In this video segment from Nature, learn about six different breeds of cattle.
Mix two gases to explore diffusion! Experiment with concentration, temperature, mass, and radius and determine how these factors affect the rate of diffusion.
This informational text introduces students to the dinosaurs found near the polar regions and discusses the adaptations that allowed these dinosaurs to survive in a dark and cold environment. The text is written at a kindergarten through grade one reading level. This version is a full-color PDF that can be printed, cut and folded to form a book. Each book contains color photographs and illustrations.
The disappearance of bees will have tremendous impact upon the way we live according to scientists in this segment from Nature.
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.
Scientists who are working to discover new medicines often use robots to prepare samples of cells, allowing them to test chemicals to identify those that might be used to treat diseases. Students will meet a scientist who works to identify new medicines. She created free software that ''looks'' at images of cells and determines which images show cells that have responded to the potential medicines. Students will learn about how this technology is currently enabling research to identify new antibiotics to treat tuberculosis. Students will complete hands-on activities that demonstrate how new medicines can be discovered using robots and computer software, starring the student as ''the computer.'' In the process, the students learn about experimental design, including positive and negative controls.
Students learn about memory by doing a memory-writing exercise, studying the brain to understand how it affects memory, reading Li-Young Lee's poem "Mnemonic," and creating projects to demonstrate their understanding.
This student-centered Exploration Routine can be used in many different ecosystems and provides a way for students to search for, observe, research, and share discoveries about organisms. It can be used with any type of organism or phenomenon you choose for students to focus on, such as macro-invertebrates in streams or ponds, under-log organisms, insects caught with nets, or plants.
This video segment adapted from A Science Odyssey tells the story of researcher Sir Alexander Fleming, whose luck and scientific reasoning led to the groundbreaking discovery of penicillin.
In this video segment from NatureScene, observe some methods of plant identification with regards to the diversity of hardwoods at the Congaree Swamp.
This video segment from the Science and Technology Chat series focuses on dolphin pregnancy, birth, and care of the young, and features Atlantic bottlenose dolphins living in captivity at the Mirage Resort Dolphin Habitat.
Dr. Stephen O'Brien of the National Cancer Institute discovers a 700-year-old mutation that makes a person resistant to HIV infection. From Evolution: "Evolutionary Arms Race."
This video segment from Kentucky Life explains the differences between dragonflies and damselflies and explores their habitats.
This class is a multidisciplinary introduction to pharmacology, neurotransmitters, drug mechanisms, and brain diseases from addiction to schizophrenia.
