Ideal for your electricity unit, especially with middle schoolers, this lesson plan gets engineers using multimeters in electrical circuits to explore the relationships among voltage, current, and resistance. Older learners may even plot...

Transform your classroom into a fully functioning weather station with this series of hands-on investigations. Covering the topics of temperature, precipitation, wind patterns, and cloud formation, these activities engage young...

It's hot today, but is that the weather or the climate? This colorful presentation isolates both concepts to allow for better understanding by covering the positioning of the planet, making comparisons of land versus water, and looking...

Four types of air masses interact in the atmosphere above the US. The collision of these air masses forms a front, which, in turn, creates our weather. Concepts are explained by Sam and RJ, thus preventing a snowball fight. Your class...

Introducing your class to weather concepts is a breeze with this fresh film! It differentiates between weather and climate, describes the factors that affect weather (temperature, air pressure and humidity), and displays Earth's climate...

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...

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...

The sun heats Earth's surface unevenly, causing crazy weather patterns around the globe.  A NOVA video describes the resulting changes in air pressure, temperature, humidity and their impacts on weather. It connects the concepts to...

It's amazing how easy it is to forget that every second of our lives we are being pushed on by an uncountable number air molecules. Explore with your class the concept of air pressure and how it affects our bodies, the earth's...

Introduce your class to air masses and how they affect the weather with a lesson that focuses on the differences between high and low air pressure systems. The class explores actual weather data using archived weather data.
