This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"A new addition to the International Space Station marks the beginning of exciting new explorations of exotic matter. This is BECCAL, the Bose-Einstein Condensate and Cold Atom Laboratory. A joint venture between NASA and the German Aerospace Center, BECCAL will enable scientists across the globe to eliminate one pesky force that plagues earthbound experiments: gravity. A Bose-Einstein condensate is a state of matter formed by cooling a gas of extremely low density to just above absolute zero. Systems like this enable scientists to study aspects of quantum mechanics on a relatively big scale, and could hold the key to bridging quantum mechanics to general relativity. Methods for generating Bose-Einstein condensates vary according to how they trap atoms, using either optics or magnets to do the trick. But typical experiments are hampered by the force of gravity. In a standard setup, gravity deforms optical and magnetic traps..."

Student groups compete to design a process that removes the most iron from fortified cereal. Students experiment with different materials using what they know about iron, magnets and forces to design the best process for removing iron from the cereal samples.

Short video on electrolyte balance with regard to potassium for anatomy and physiology.

In this lesson, students will learn that minerals are a necessary part of our diet. They will learn that different minerals have different functions in the body. More specifically, they will discover that iron is necessary to carry oxygen around the body. In the associated activity, students will design a process that removes the most iron from the cereal.

Working through a calculation for K-Ar dating (good to have some prior experience with e and logarithms). Created by Sal Khan.

"Plant diversity is quickly dwindling across the world. That’s put our planet’s pollinators in danger. Pollen contains a variety of nutritional elements that are key to life itself. Not only are global changes affecting pollen amounts, they’re also affecting pollen varieties. This means that many pollinators, including bees, aren’t eating the best-balanced diet they need to survive. Understanding how the elemental ingredients in pollen affect different traits in bees, such as their survival, body mass, and ability to protect themselves, could help scientists determine whether and how the scarcity of specific nutrients affects them. And it could lead to new ways of conserving pollinators and the critical roles they play in many ecosystems. For their part, researchers from Jagiellonian University in Poland examined the effects of an inadequate supply of potassium, sodium, and zinc in pollen on _Osmia bicornis_, the red mason bee..."
