In this video, we explore the fascinating discoveries of Hans Orsted in the mid 1800s regarding electricity and magnetism. We learn how electric current flowing through a wire produces a magnetic field and how the strength of this field...

Paving the way for modern democratic society, the ancient Mediterranean world traded goods and ideas across three continents over thousands of years.

This video English lesson looks at idioms and expressions associated with the word hammer. Idioms can be tricky for students to learn, but through the use of appropriate visual imagery, this video helps students to quickly learn and use...

Metal-eating bacteria are turning the giant wreck into dust, but for a king’s ransom you can still dive down to see it.

The video is a tutorial on how to balance chemical equations. The instructor goes through three different equations, counting the number of elements present on each side and then adjusting the coefficients to balance the equation. The...

Why are we ignorant of the archaeology left behind in West Africa? Are West Africans going to rediscover their history and will there be a demand of giving back physical objects from foreign museums in aiding that rediscovery? West...

Dr. Kyle Huff explains what is Scientific Management

1) Theory behind the triple sugar iron (TSI) in microbiology. 2) How to identify A/A, K/K, and K/A reactions. 3) How to identify production of gas and/or hydrogen sulfide (H2S).

A new international study has measured the densities of the seven Earth-size planets around TRAPPIST-1 with extreme precision

Whatever is inside the earth is very hot. The trail of clues leads to the model of a metallic core surrounded by a rocky mantle. Huge, slow convection currents rise up, often resulting in earthquakes and volcanoes.

The video is a lecture presentation on the extraction of metals. The presenter begins by discussing how the method used to extract a metal from its ore depends on the metal's reactivity. The lecture then covers the extraction of iron...
