Crystals are what happens when matter gets organized. Atoms, ions, or molecules line up in repeating patterns, building solid structures that can be seen with the naked eye or only under a microscope. This invisible order is what gives crystals their characteristic shapes, colors, and properties, whether they form deep underground, in a metal pot …
The formation of potholes. Water is one of the few liquid compounds that expands when it freezes, instead of contracting. The power of expansion packs a destructive punch. It is responsible for causing extensive damage to streets and roads all over the world. While the freezing and thawing of water is one of the driving …
Bismuth crystals.

All you need for this is a stove, a stainless steel pot, and a stainless steel spatula. Take a look …
More than 350 million years ago, warm, shallow seas covered many parts of North America, including much of the Midwest. During this time period, known as the Devonian era, these shallow waters were teaming with salt water marine life. Fish, mussels, crustaceans, and micro-organisms flourished in the region.

You’ve likely already heard about our planet’s oceans warming up, but what about the lakes? Well, those are heating up as well, according to UPI. A new study published in Geophysical Research Letters has found that the world’s lakes are increasing in temperature by an average rate of 0.61 degrees Fahrenheit each decade. This outpaces the ocean …
