Scientists have been searching for alien life by honing in on the existence of liquid water, but we might be overlooking some types of life out there that doesn't need water at all.

Water can dissolve more substances than anything else on earth...so why doesn't it dissolve everything away?

As we keep pumping carbon dioxide into the atmosphere, more of it is dissolving in the oceans, leading to drastic changes in the water's chemistry. Triona McGrath researches this process, known as ocean acidification, and in this talk...

In this video students will observe that regardless of the type of change that occurs in heating, cooling, or mixing, the total weight of matter is conserved. A hands-on demonstration helps students set-up their own activity to prove...
