Regional Differences

The climate at the equator is hotter than the climate at the poles, but why? The lesson goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong lamp,...

The three types of rock aren't classic, punk, and hard. The chapter covers everything scholars need to know about rocks. Pupils compare rocks, learn about their formation, see how rocks change, and follow every step of the rock cycle....

Animals have evolved to communicate in different frequencies so they can hear each other throughout the rainforest. The first lesson in a three-part series begins by exploring an interactive story map online about the Borneo rainforest....

Ten percent of the world's forest carbon stores exist on the 18 percent of land legally owned by indigenous people. The first lesson in a series of four discusses the way different groups of people treat the land and forests. Scholars...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Which is worse — drought or flooding? Neither is helpful to the environment, and both are increasing due to climate change. The 16th lesson in a series of 21 covers the average precipitation trends for two different climates within the...

At the age of 18, the human brain stops growing. �An informative video specifically focuses on the central nervous system. The narrator discusses its location, the function of our brain, and its development from embryo to adult. He also...

Students use real satellite data to determine the changes in near-surface air temperature at different times of the year over the Caribbean Sea. They discover how Earth's tilt causes seasonal differences in incoming solar energy. They...

Students use a NASA satellite data to contrast amounts of cloud coverage over different climate regions in Africa. They explore how Earth's major air circulations affect global weather patterns, and relate to local weather patterns.

Using NASA's Live Access Server, earth scientists compare the temperature, precipitation, and normalized difference vegetation index for four different locations. They use the data to identify the climate zone of each location using...
