There is water all over Earth in different forms. By far, most of the planet's water is in the oceans, but it is in other places as well. Sometimes water is a liquid, sometimes it is a solid, and sometimes it is a gas. These changes in the states of matter are the result of the water either gaining...

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...

A watershed is the area of land that water flows over to reach a river, lake, or a stream. Near the upslope edges of a watershed, small tributary streams (1st, 2nd and 3rd order) begin gathering water that flows downstream into larger rivers and eventually drains into a river, bay, or ocean. Some of...

Many things contribute to a healthy watershed. Certain land cover types like farm fields, cow pastures, sewage treatment plants and landfills are sources of nutrient and sediment pollution to streams. Rain falling on hot parking lots and rooftops in the summer delivers warm runoff water to streams....

A transit happens when a planet crosses in front of a star. From our perspective on Earth, we only ever see two planets transit the sun: Mercury and Venus. Both are pretty rare events. Transits of Mercury happen only about 13 times per century and the next transit of Venus won't happen until 2117!...
