Water in its liquid state is visible, as ponds, streams, water in bottles, and wet surfaces. You can also see water in its solid form , ice and snow. Water as a gas in the air, also called water vapor, is invisible. The process of visible liquid water turning into invisible gaseous water is called...

Earth's temperature is set, in part, by a balance between incoming radiation energy from the Sun and outgoing radiation energy into space. If more energy comes in than leaves, Earth's temperature will rise, and vice versa. The atmosphere plays a big role in this balance. In this activity, you will...

The greenhouse effect is the name scientists use to describe how heat accumulates in Earth's atmosphere. A majority of the energy from the Sun arrives at Earth as visible radiation. This energy passes through our atmosphere and warms Earth's surface. The warmed surface re-emits invisible infrared...

"Some days it feels """"""""dry"""""""" and some days it feels """"""""muggy-"""""""" even though the temperature is the same. This is due to differing amounts of water vapor in the air. In this activity, you will measure relative humidity in the air using just a temperature sensor, by comparing the...

There is always some water vapor in the air. For the most part we can't see it directly, but we can measure its presence with a relative humidity sensor. In this activity, you will use a relative humidity sensor and a soda bottle to measure humidity near surfaces, such as over a leaf or above an ice...

Much of the water cycle is visible, both in the form of liquid water (oceans, rivers, lakes, and precipitation such as rain) and in the form of solid water (ice, snow, and precipitation such as falling snow or hail). However, some of the water in the water cycle is invisible because water is also...
