Covering some 70 percent of Earth's surface, clouds play a key role in our planet's well-being. But how do they form, why are there so many types, and what clues can they give us about the weather and climate to come? Try your hand at classifying clouds and investigating the role they play in severe...

Learn how to identify cloud types by using this flow chart from the International Cloud Atlas. Clouds are divided into 10 fundamental types known as genera, depending on their general form. The genera are then further subdivided based on a cloud's particular shape, structure and transparency; the...

What does up, must come down. Precipitation is the most commonly seen aspect of the hydrologic cycle. Students will learn how the water cycle works using 3-D paper craft activity. The students will see a demonstration of the concept of precipitation.

Barometers using mercury are heavy and fragile. The first working version of an aneroid (without water) barometer was built in 1843 by French scientist Lucien Vidie. This made the barometer very portable and it became a commonly used meteorological instrument. It was still calibrated to the...

The amount of air over us is constantly changing. As a result, the weight of that air, called pressure, is constantly changing. These changes in air pressure are indications of changes in our weather. We measure this change using a device called a barometer (bar-meter or measurer).

Pressure is not only a matter of altitude but also dependent upon the temperature. As the temperature increases so does the pressure. The molecules and atoms that comprise the air we breathe gain energy as they absorb heat. That increase in energy results in faster moving atoms which we observe as...

Bernoulli's principle states that in fluid flow, an increase in velocity occurs simultaneously with decrease in pressure. The students will discover that the faster air moves (air acting as a fluid), the lower the pressure beccomes within that air flow. They will see this effect blowing between two...

Students use prior knowledge, a photo gallery, and a video to discuss what they already know about extreme weather on Earth and brainstorm and categorize a list of weather-related words and phrases. Then they identify the necessary conditions for weather events to occur, and the factors that affect...

With this graph and accompanying lesson from Clue into Climate, produced by KQED, students will explore how the level of carbon dioxide has increased over time, hypothesize about why this is a concern, and begin to think about what can be done to slow or stop continued climate change.

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...

"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.

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...

We commonly experience the fact that in hot weather, lower humidity is more comfortable than higher humidity. Why? In this investigation, you will figure out how to condense water from your classroom air.
