One of the key things to know, in deciding how to motivate your people is 'what is your Psychological Distance?' As a Project Leader, one of your critical jobs is keeping your team motivated. We all learn about motivation - some more...

We deal with light on a daily basis, and it has wave-like characteristics that are essential to many natural and technological processes. The wave nature of light aids in the explanation of a number of important optical phenomena,...

In this experiment, our Testers compare the problem-solving abilities of ants and children. With the help of Audrey Dussotour from CNRS, they set up a test to see if a colony of ants can find the shortest path to food faster than a group...

The Automated Transfer Vehicle (ATV) is a spacecraft developed by the European Space Agency for resupplying the International Space Station. It carries essential supplies such as water, food, and experimental equipment. After docking...

This video highlights the incredible discoveries made by the Cassini spacecraft during its mission at Saturn. From capturing exquisite views of the ringed planet and its moons to uncovering new radiation belts and studying the internal...

The Automated Transfer Vehicle (ATV) is a spacecraft developed by the European Space Agency to resupply the International Space Station. With a payload capacity of 20 tons, the ATV carries essential supplies including water, food, and...

In this fun engineering challenge, your students will build rubber band-powered cars using the engineering design process and compete to see how far they can go.

This video serves two purposes: it introduces us to a structure for problem solving and gives some example Ideal Mechanical Advantage problems. This video is intended for Engineering students at Arsenal Tech HS.

In this video we review some practice problems about Actual Mechanical Advantage and Efficiency. This video is intended for Engineering students at Arsenal Tech HS.

In this video, you will learn about Friends functional notation with our distance program. This clip is from the chapter "Module 3" of the series "Fundamentals of Object-Oriented Programming - C++".In this section, you will learn about...

Bohr's model of the atom says that an electron's energy is set by its orbit around the nucleus. Bohr said that electrons have specific, quantised levels of energy, and that the size of the orbit affects the energy level. An electron's...

Jim Steinmeyer designs magic tricks that other magicians use. He knows the ins and outs of illusion. He's written several books on the subject and, in one, he claims, "Magicians don’t protect their secrets from the audience, they protect...

This video helps students understand the nature of waves, and enables them to create their own waves. Through experimenting with waves students will identify the various features of waves, and what makes waves different from each other....

Traffic is one of the biggest problems plaguing cities today. Idling cars cause increased emissions, more traffic means more accidents, and it is, of course, annoying. Meet traffic scientist, Dr. Alex Bayen who is working to solve...

How the universe works: a black hole is surprisingly hard to fall into.

Insane (for the time) Voyager engineering.

Almost everything you could want to know about Callisto.

The journey of Voyager I and II beyond the orbit of Neptune.

Hubble's images of Icarus, Earendel and HD1.

Almost everything you could want to know about New Horizon's visit to Arrokoth.

The Halley Armada, Giotto, Vega 1 and 2, Suisei and Sakigake, all visited Halley's Comet at roughly the same time in 1986. What did they discover? Why was this such a groundbreaking mission?
