The Cloud Case

Condensing water warms the air around it. Young scholars consider this concept as they experiment with air temperature around evaporating and condensing water vapor. They simulate the formation of clouds to experience the associated...

What's the best way to record temperature over a long period of time? Scholars learn about collection of weather and temperature data by building thermistors in the fourth installment of the 10-part Discover Your Changing World series....

In collaborative groups, mini-meteorologists investigate the conditions that must be present for clouds to form: cooling air, water vapor, and condensation nuclei. In addition to procedures, a chart for observations and some follow-up...

Vapor pressure is the focus of this chemistry video. Sal explains that when molecules are "sticking together," a substance takes on a liquid or solid form. However, when kinetic energy increases, the molecules are forced apart, allowing...

Does it feel a little humid in here? Learners assume the role of water vapor in the atmosphere as they explore the differences between warm and cold air. They roll dice to determine their level of energy, which determines if they...

It is more than just blowing hot air. Pupils first build a hot air balloon out of tissue paper by cutting enough panels of tissue paper to form a balloon shape and glue the panels together. Using a hot air gun, individuals then inflate...

Blow your class away with a gust of humor as they watch this video about air pressure and wind. Along the way, they find that the density of air (as determined by temperature, altitude, and water vapor content) leads to air pressure...

Support science instruction with a combination of engaging activities and skills-based worksheets that focus on clouds. Learners take part in grand discussions, write an acrostic poem, complete graphic organizers, solve word...

Introuduce your scientists to the differences in air at varying altitudes with a colorful explanatory graph. After some discussion, they view unbelievable footage of mountain-climbing Leo Houlding and a narrative about how he might do...

Humans aren't the only species to build structures with air conditioning—we weren't even the first! The video explains how a variety of species that live under and above ground design their structures to allow for air circulation. It...
