Paleontologists today look at more than just fossil evidence to learn about organisms that lived millions of years ago. In this episode, host Emily Graslie seeks to answer the question, "How did mammals develop their specialized movements?" Part of "The Brain Scoop" series.
With support from the National Science Foundation’s Human-Centered Computing Program (HCC), Stanford University mechanical engineer Mark Cutkosky and his team are using volunteer test subjects to find out if the way walk is wearing out their knees. One of the major problems at the root of knee pain is uneven wear and tear on the knee cartilage, which leads to arthritis. Cutkosky’s research, known as Movement Retraining, focuses on alleviating pain by analyzing and possibly changing a person's stride. The goal is to slow the rate at which arthritis progresses and thereby delay or even eliminate the need for surgery. Part of the National Science Foundation Series “Science Nation.”
New research led by scientists at the University of California, Berkeley, suggests that the shape of some animals' pupils could reveal whether one is hunter or hunted. An analysis of 214 species of land animals shows that a creature's ecological niche is a strong predictor of pupil shape. Species with pupils that are vertical slits are more likely to be ambush predators that are active both day and night. In contrast, those with horizontally elongated pupils are extremely likely to be plant-eating prey species with eyes on the sides of their heads.
Students will explore how molecular movement is related to temperature, and how temperature can be measured. Important terminology includes thermometer, thermal energy, kinetic energy, potential energy, energy conversion, molecules, and heat.
Vertebrates use their backbones to move in a variety of ways. Observes and comments on the movement of fish, moray eels, newts, salmon, cheetahs, dolphins, birds, and babies. Highlights the differences and similarities of their movement. Motorized models reveal precisely how some animals' backbones move.
Pinky and Petunia discuss light and electron microscopes. They also offer helpful hints on how to use a light microscope. Part of "The Amoeba Sisters" series.
Breakfast cereal was the birth of the health food movement. Before that, breakfast was usually a fatty and vein-clogging combination of bacon, fried eggs, flapjacks, and a mound of butter. The advent of corn flakes, oatmeal, and other quick-to-prepare breakfast foods changed the way people start their day. Part of the "Science to Go With Dr. Joe Schwarcz" series.
In this episode, host Emily Graslie discusses the anatomy of various mammals and how they move. Tetrapods generally use three different types of locomotion. Graslie highlights three groups of animals and the science behind their movements: plantigrade animals, digitigrade animals, and unguligrade animals. Part of "The Brain Scoop" series.
Part of the "A 3-D Demonstration" series. Explores the basic principles behind the operation of AC and DC motors. Explains how one or more fixed magnets, either permanent or electromagnetic, can cause linear movement or rotation of a current-carrying wire. A hand rule is developed to predict motor force. Motor torque is explained as a prelude to the practical design of a direct current motor. Specific modules include Motors and Magnets, Current and Magnet Interaction, Left-Hand Rule, Motor Force, Motor Torque, and DC Motors. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Discusses the various body structures that enable microorganisms to move and function in their habitats. One of nine segments in a series, with all nine available on a DVD.
Surveys soil's formation, composition, properties, types, and movement. Also identifies the five major plant communities: tundra, forests, scrublands, grasslands, and deserts. The connection between soils and vegetation affects where people live.
Part of the Project-Based Inquiry Science "Earth Science Content Videos" series. Modules include the following: "Mantle Simulation: Hot Water in Cup," "Mantle Simulation: Cold Water in Cup," "Mantle Simulation: Cardboard," and "Plate Interaction Animations."
While it may not always seem possible, Earth is continually changing. Students gain insight into geological processes such as the formation of land, erosion, and volcanic eruptions. Other Earth processes are also investigated.
The Earth has many land formations such as mountains, plateaus, hills, and plains. These formations are created by movement of the earth’s plates, volcanoes, weather, and erosion. Part of the Real World Science series.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. For this particular video, students will receive tips for being prepared in the event that an earthquake occurs. Part of the Science Video Vocab Series.
In this episode, scientist Steve Lord discusses the findings of astronomer Edmond Halley, and his discoveries related to the movement of stars. Halley used ancient Greek records to prove that stars move as they orbit within their galaxies. Part of the "Ask an Astronomer" series.
Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many scientific fields. Part of "The Amoeba Sisters" series.
A ball flying through the air, a deer walking in the woods, and a flowing river - these are all examples of moving objects. Students explore the characteristics of things in motion, and special attention is given to the forces that initiate and change their movement. Concepts and terminology discussed include: motion, push, pull, force, direction, and speed.
What are the differences between solids, liquids, and gases? In this program, students will investigate real-life examples of the various phases of matter. Colorful animations illustrate how these states differ based on the movement of particles. Other topics covered include plasma, crystalline and amorphous solids, viscosity, freezing, vaporization, evaporation, and condensation.
