Watch Earth's magnetic shield protect the planet from a pelting by the solar wind. See how the sun's energy drives a remarkable planetary engine, the climate. This video, originally created by NASA's Scientific Visualization Studio as...

Scientists say the increased melting of arctic freshwater is causing an imbalance in the salinity of seawater, and this could lead to plummeting temperatures in the northern hemisphere.

El Niño is a recurring climate pattern characterized by warmer than usual ocean temperatures in the equatorial Pacific. Two back-to-back 3-D visualizations track the changes in ocean temperatures and currents, respectively,...

This video is answering the question of what is a conductor.

MAVEN is the first spacecraft specifically designed to study the Mars upper atmosphere, in order to better understand the evolution of its climate. By measuring windspeed and direction near the top of the...

After being delayed over a year due to the pandemic, a NASA field campaign to study the role of small-scale whirlpools and ocean currents in climate change is taking flight and taking to the seas.

The video is a lecture presentation on the characteristics of the human eye. The presenter introduces an experiment conducted by Matt to investigate the relationship between the current through a fixed value resistor and potential...

A rip current is a strong channel that flows seaward from the shore. Rip currents are common to surf beaches, which are coastlines with breaking waves. Rip currents, commonly referred to by the misnomer riptide, cause more than 100...

Five years after NASA’s MAVEN spacecraft entered into orbit around Mars, data from the mission has led to the creation of a map of electric current systems in the Martian atmosphere....

Human caused climate change is rapidly melting arctic ice and disrupting ocean currents, which could make Western Europe cooler.

If you're looking to learn more about transistors, then this video is for you! In this video, we'll discuss what transistors are, what they do, and how they're used in modern day technology.

The video is a lecture presentation on VI characteristics, where the speaker demonstrates how to investigate the relationship between the current through a light bulb and the potential difference across it. The speaker shows how to...

With support from the National Science Foundation's (NSF) Emerging Frontiers of Research and Innovation (EFRI) program, bioengineer Gert Cauwenberghs, of the Jacobs School of Engineering and the Institute for Neural Computation at the...

The Ocean is essential to life on Earth. Most of Earth's water is stored in the ocean. Although 40 percent of Earth's population lives within, or near coastal regions- the ocean impacts people everywhere. Without the ocean, our planet...

This video explains the motor effect, which occurs when a current-carrying conductor is placed in a magnetic field, creating a force between the conductor and the magnet. The video discusses how to calculate the magnitude and direction...

This is a lecture video on the differences between direct and alternating potential difference. The video defines and explains the two types of current and provides examples of each. It also includes graphs that demonstrate how potential...

This nugget explains Ohm's law and its derivations for a system of cells in series and parallel.

This video explains the difference between series and parallel circuits in modern electronics, and introduces Kirchhoff's Laws to help understand the calculations involved. It also discusses how circuits can be combined and the...

A description of basic parallel circuit analysis with Arduino.

Watch a soda can rip itself apart in a fiery explosion at 11,000fps with a Phantom high speed camera. Running a current through a coil, produces an electromagnet. Turn up the voltage in this experiment, and make that current strong...

This video provides an overview of the world's oceans, their importance in regulating the environment, and how climate change is negatively impacting them. It explains ocean currents, the Gulf Stream, and the global conveyor belt,...

This nugget explains the forces of attraction and repulsion between two current carrying conductors. It also explains the working of Roget's spiral to illustrate these phenomena.

In this lesson, students will learn how to determine whether two events are independent or not. They will understand that independent events are not influenced by each other and that the probability remains the same regardless of...
