Cheer on the competitors in this zany science cook-off, where teachers compete before a live webcast audience for the sought-after title, "Iron Science Teacher." Recorded live at the Exploratorium 2015
An element for the modern age, lightweight lithium is commonly used in rechargeable batteries, fireworks, and medications for treating bipolar disorder. Lithium is highly reactive, and has served as a fuel source for nuclear weapons as well as a cooling agent in nuclear reactors. See its scarlet contributions to pyrotechnics, and discuss its divided reputation as being both restorative and potentially toxic to our health.

Zeke Kossover is a Teacher-in-Residence at the Exploratorium Teacher Institute, where he trains and supports coaches and mentors who work with novice science teachers in the classroom. For fun, he puts on physics circus shows that work as magic shows in reverse--making confusing things easy to understand. Recorded live at the Exploratorium 2015
Plumb the dark and dangerous worlds of commercial diving and marine construction with Thomas Belcher, President of Underwater Resources, Inc., and learn how helium enables deep-sea divers to safely breathe under pressure. Recorded live at the Exploratorium 2015
Helium is the second most abundant element in the universe. Then why is there a global helium shortage? Follow the trail of our spendthrift affair with this elusive noble gas, and find out why its future remains up in the air.
Learn about heliums many uses, from cooling magnets in MRI machines to enabling deep-sea divers to safely breathe under pressure.
Featuring: A People's History of the Periodic Table with Paul Stepahin Join us for a live webcast with senior scientist Paul Doherty to discuss breaking news about the Rosetta Mission!
The European Space Agencys Rosetta mission deployed its lander, Philae, to the surface of Comet 67P/ChuryumovGerasimenko on November 12. 2014. Philaes landing site, currently known as Site J, is located on the smaller of the comets two lobes, with a backup site on the larger lobe. The sites were selected just six weeks after Rosetta arrived at the comet on August 6, following its 10-year journey through the Solar System.
Join us for a live chat with educators and scientists aboard the Exploration Vessel
Nautilus, which is studying an active volcano beneath the Caribbean Sea. Learn about
the excitement of deep-sea exploration, and find out whether the researchers have had
to dodge any underwater volcanic eruptions. Join us as Rosetta moves ever closer to Comet 67P/Churyumov-Gerasimenkos nucleus to map potential sites for a November landing.
