Phones, TVs, solar panels, and electric car batteries are all made of some rare and unusual elements. As our modern world creates more and more of these technologies, will things go from "rare" to "nonexistent" and what will we do then?

This week we’re headed out to sea for some marine engineering. How do we design ships to handle aquatic environments? How do we deal with marine life and corrosion and all of the other problems that come with engineering in the ocean?...

The welding process usually involves pretty extreme levels of heat. But it turns out that in the cold vacuum of space, metals can weld together... automatically.

Population III stars were the very first stars in our universe and far larger than any we can see today. Where are they now?

Gems are more than just pretty rocks!

Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of the...

In this video Paul Andersen explains how metallic solids form when delocalized electrons hold the positive nuclei in an electron sea. This model helps to explain the properties of metals like conductivity, shiny appearance,...

In this video Paul Andersen explains how metallic bonding structure creates the different properties of metals. The electron sea model explains how the positive nuclei are locked into a negative sea of delocalized electrons. This...

In this video Paul Andersen explains how humans are impacting the Earth through farming, mining, pollution and climate change. According to the NGSS wise management can reduce impacts on the planet. This will become more important as...

Even an empty lunch sack is useful to science. You can examine it and come up with some traits. In this episode, Sabrina chats about things like malleability, hardness, conductivity, and magnetism. And all with lunch! This first series...

The planets in our solar system have a very specific order. But have you wondered why they have the order they do?

Mr. Andersen describes the major groups on the periodic table.

In this video Paul Andersen explains how the resistivity of a material opposes the flow of charge. Conductors (like metal) will have a low resistivity and insulators will have a high resistivity. Semiconductors will have a moderate...

High in the Andes, lies the world's largest reserves of the mineral lithium which is likely to help power the electric and hybrid vehicles of the future. The lithium is locked in the brine of Salar de Uyuni, the largest salt flats in the...

A common complaint that math teachers hear is, "When am I going to need this in the real world?" When you're sitting in algebra class, it's easy to feel like it's all theoretical–a bunch of imaginary numbers and rules dreamed up by...

Howcast - Learn how to pick welding rods from sculptor DeWitt Godfrey in this Howcast video.

Howcast - Learn what solder is from expert Jeff Koskulics in this Howcast video.

If you like things shiny and bright, you're probably a fan of chromium, a metal used to plate other metals, commonly known as chrome.

Welcome back to the Fluctus Channel for a special episode on the ship recycling industry. This episode will highlight the beaching method employed by the world's largest ship-breaking yards in India, Bangladesh, and Pakistan,...

Deep sea mining, seafloor vents, underwater drones, bioluminescent sharks, and the disturbing effects of ocean acidification highlight the near future of oceanographic discovery.

A covalent compound forms when electrons are shared and this will happen when you have 2 nonmetals, or 2 anions, bonding together. The reason these elements share their electrons is because they have a small difference in...

This video explores the layers of the Earth, from the crust to the inner core, comparing it to the layers of a sandwich. They discuss the composition and characteristics of each layer, highlighting the unique properties of the mantle,...

Electrical conductivity varies from metals to insulators. Solids can be divided into three categories: conductors, insulators, and semiconductors. Conductors are solids through which electricity can flow to a large extent, classified as...

Explore the Core Building at The Eden Project, designed based on the Fibonacci sequence and built with sustainably sourced materials. Learn how the rainforest biome, home to nearly 2,000 plant species, is maintained by a dedicated team...
