Greenhouse in a Beaker

Carbon is naturally found in the atmosphere. Carbon dioxide, or CO2, itself is not considered a pollutant. The CO2 being released from burning fossil fuels was part of the atmosphere hundreds of millions of years ago before being captured by plants and sea organisms.

Groundwater Movement

Water that accumulates beneath the surface of the Earth is called groundwater. Contrary to popular belief, groundwater does not form underground "rivers," but is actually found in the small spaces and cracks between rocks and other material such as sand and gravel. The following activity involves learning how water moves through rock materials such as sand, gravel, and clay.

Grow Your Own Crystals

Most minerals happen naturally as crystals. Crystals are made of specific atoms or molecules joined to make distinctive repeating patterns. The crystals that make up many kinds
of minerals are formed deep underground through the interaction of fluid, pressure, and temperature. Some minerals form at or near the surface. You may have seen spectacular mineral samples in museums, but you might not be aware that minerals are everywhere, including in your body.
