In Australia, scientists have found dolphins using tools to find food. The bottlenose dolphin has been observed covering their beaks with basket sponges as they forage for food. The sponge helps them uncover fish hiding in the sandy sea bottom and protects their snouts from scrapes and stings. Part of the "News of the Day" series.
With support from the National Science Foundation, device engineer Jason Heikenfeld of the University of Cincinnati and a multidisciplinary team are developing new technologies to take sweat biosensors to the next level. Their wearable patches allow tiny amounts of sweat to be captured and analyzed quickly and accurately with strong correlation to blood data. The researchers envision a day when data from continuous sweat monitoring will be an essential tool in health care, like blood tests. Part of the "Science Nation" series.
Northwestern University Mechanical Engineering professor Todd Murphey and his team are engineering robots to mimic humans. With support from the National Science Foundation, the team is using algorithms to enhance a robot’s ability to adapt to human behaviors. Part of the "Science Nation" series.
Though tool use is not unique to humans, their sophistication and degree of reliance upon them is unique, and sets humans apart from other species. So when did human tool-making begin, and why? And what does the use of tools reveal about the evolution of human ancestors? Paleoanthropologist Tim White reveals the answers in this short video.
With help from the National Science Foundation, physicists at MIT have created 35 “Fab Labs.” They can bring relatively sophisticated design and manufacturing capability to people around the world with four simply tools. At last count, they were in use on three different continents, helping to create everything from critical infrastructure to simple art work.
Everyday people do work, and most of the time they use tools to help them. First, students gain an understanding of work. Next they explore the relationship between work and energy. Common examples of tools used to make work easier are highlighted. Concepts and terminology discussed include: work, energy, machine, simple machine, wedge, wheel and axle, and lever.
Students will learn how to measure length and distance using common tools. Concepts and terminology include metric ruler, meter, centimeter, and kilometer.
A donkey is born blue, and his owner hates him. The owner decides to paint the donkey grey. From the Kool Books series narrated by Hector Bonilla.
Uses practical examples to help students understand and use the components of the scientific method. Concepts and terminology: hypothesis, experiment, measuring, data, analysis, and conclusion.
Demonstrates how to observe and record scientific observations. Concepts and terminology: observation, data, recording, data table, tools, safety, measuring, and graphs.
In this episode, host Alex Dainis takes viewers on a tour of her lab. She points out important equipment and tools and explains their purpose in the conducting scientific experiments.
Hundreds of tools exist for the production of audiovisual products and when properly used excellent quality and beauty is delivered through image and sound. The host, Nerdo Cavernas, talks with experts and takes viewers into the world of audiovisuals.
Follow a structural engineer through a busy day of working with sophisticated design tools. He is tasked with creating safe, long-lasting structures. Part of the "Career Connections" series.
Magnets are unusual and fun tools that serve many useful purposes. Students learn the characteristics and behavior of magnets. Special emphasis is given to electromagnets and the importance of magnets in generating electricity. Concepts and terminology include bar magnet, pole, magnetism, magnetic field, repel, attract, and compass.
Students explore the relationship between observations and measuring things in science. Specific ways of measuring length, mass, volume, and temperature are demonstrated using tools common to the classroom. Other terminology includes unit of measurement, meter stick, metric ruler, balance, graduated cylinder, and thermometer.
In this episode, host Emily Graslie highlights the suckermouth armored catfish, dinosaur fossils, and a group of parasitic ants. Part of the "Natural News From The Field Museum" series.
Sea otters, the ultimate surf bum, are the crucial element for kelp forests and their diverse ecology. Reviews the history of otters on the Pacific coast and their near extermination. Describes the otters' habitat, physical characteristics, behaviors, diet, and use of "tools." This member of the weasel family has the lushest fur in the world.
NASA aerospace engineer Victoria Garcia describes how she uses virtual-reality tools to design living and work spaces for astronauts. She also talks about not allowing deafness to be a barrier in her life. Part of the "Design Squad Nation" series.
Professional remodeler Danny Lipford offers practical home improvement information to homeowners. Discusses products and ideas for saving money on energy bills: caulking, expandable foam sealant, weather stripping, thresholds, insulated socket sealers, attic and window insulation, water heater blankets, and compact fluorescent light bulbs. Looks at using a flexible wheelbarrow screen for sifting rocks from soil. Talks about Dremel cordless tools. Gives reasons why homeowners should use mulch.
Explains how scientists learn about dinosaurs. Paleontologists use detective techniques to uncover fossils. They deduce how dinosaurs lived, what they ate, how they moved, and how they cared for their families. Visit a dig and learn how fossils are preserved for study. Watch a skeleton be reconstructed. Leslie Nielson hosts this live-action/animated presentation.
