Water covers over 70% of the Earth, cycling from the oceans and rivers to the clouds and back again. It even makes up about 60% of our bodies. But in the rest of the solar system, liquid water is almost impossible to find. So how did our planet end up with so much of this substance? And where did it...

An earthquake causes different types of energy to radiate from the epicenter. The P and S waves are the first two to arrive at any specific point. P and S waves have different motions and shake the earth differently as they travel through it. In this activity, students demonstrate the motions of S...

Just as air can have different densities, water can have different densities as well. As the salinity of water increases, the density increases as well. Fresh eggs will float in saltwater, but will sink in freshwater. This will show that as the salinity increases the density also increases.

We all know the oceans are salty but so are other sources of water. The oceans have a salinity (salt content) of 35%. The Dead Sea has an average salinity of 290%, almost nine times saltier than the oceans. But what actually does that mean? Just how salty tasting are these various bodies of water?...

There are three states of matter: gas, liquid, and solid. Water in our atmosphere exists in these three states constantly. As the temperature of water vapor (a gas) decreases, it will reach the point at which it turns into a liquid (called the dew point or the point at which dew forms). This change...
