Lab experiments demonstrate a variety of ways to detect carbon and hydrogen in organic substances. Burns hexane, benzene, cyclohexane, and naphthalene; shows properties of a propane-butane mixture.
Experiments show the production and properties of carbon dioxide and its use as a fire extinguisher. The second part demonstrates the effect of surface area, temperature, and concentration on chemical reaction rates.
Experiments feature: (1) halogens as oxidizing agents, (2) bromine reacting with potassium, (3) detecting bromine in compounds, (4) combustion of sulphur and the formation of sulfuric acid, (5) properties of phosphorus, and (6) spontaneous ignition of white phosphorus.
An amusement park provides the opportunity to study oscillatory systems and the variables associated with mechanical oscillation. After making observations at the park, a team heads back to the lab and creates experiments based on their observations. Part of Invisible Science and Technology Surrounding Series.
In this episode, Dr. Fus from Ohio State University discusses some of his science experiments. He also explains the chemistry behind some chemical reactions. As a finale, Dr. Fus demonstrates his "elephant toothpaste" experiment.
Science lab experiments demonstrate what happens visibly and at a molecular level with the Group 1 highly reactive metals and the Group 17 highly reactive halogens from the periodic table. Experiments also illustrate the range of reactivity among metals. Video has three 5-minute segments for convenience.
Scientists conduct experiments to measure the amount of starch in foods. They also show the way to measure the wind through an experiment with kites. Part of the House of Science Series.
Yana and Egbert are trying to guess what is in a mysterious box. But Izzie the Ostrich points out a potential experiment, which causes Yana and Egbert to abandon their wild guesses. This episode discusses experiments and hypothesis. Part of the "Yana & Egbert" series.
Experiments demonstrate the electrolysis of copper sulfate and the factors leading to corrosion. Other demonstrations focus on the chemical reactions of iron nails in water, sulfuric acid, sodium hydroxide, sodium chloride, and air.
Students replicate a repeated measure design experiment, called the Stroop effect, to learn about how it helps control variables in experiments. Part of the "Core Concepts in Psychology" series.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on procedures for conducting experiments in a science lab. These procedures ensure a safe environment for everyone. Part of the Science Video Vocab series.
What is a lab notebook? In this episode, host Alex Dainis explains how she uses lab notebook when conducting research. These notebooks are the primary record of research, and researchers use them to document their hypotheses, experiments, and analysis of experiments.
Experiments illustrate the presence and properties of: 1) saccharides (glucose and starch) in fruits and vegetables; 2) lipids (fats) in nuts and vegetable oils; and 3) proteins in eggs, meat, and milk. Emphasizes that chemistry is all around us.
Scientists try to find out how long it takes worms to become flies. Does the time it takes them to become flies depend on their age or on the kind of worm? The scientists also conduct experiments with balloons and lasers. Part of the House of Science Series.
A team conducts different experiments with food substances to show the chemical reactions that take place when exposed to air, heat, or extreme cold. They provide a close up on cooking technology and food chemistry from the kitchen of a restaurant. Part of Invisible Science and Technology Surrounding Series.
In this episode, host Dianna Cowern meets with math experts to discuss the phenomenon of "wine tears." They conduct experiments with various types of liquids to try and uncover the science behind this mystery. Part of the "Physics Girl" series. Please note this title uses alcoholic beverages as the basis for the experiments.
What does detergent do? The scientists research its qualities with an experiment. In this chapter, they will also conduct experiments in 2D and 3D to determine how vision works with different dimensions. The scientists will also explain the phases of the moon. Part of the House of Science Series.
Debris flows are hazardous flows of rock, sediment, and water that surge down mountain slopes and into adjacent valleys. Hydrologist Richard Iverson describes the nature of debris-flow research and explains how debris flow experiments are conducted at the United States Geological Survey (USGS) Debris Flow Flume in Oregon.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on the correct steps of preparing a microscope slide when conducting experiments in a lab. Part of the Science Video Vocab series.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on how to appropriately dress when conducting experiments in a science lab. For example, students should always wear personal protective equipment. This includes aprons, safety glasses, and gloves. Part of the Science Video Vocab series.
